Patent Description:
A plasma adsorption process refers to separating visible components (blood cells and blood platelets) of blood from plasma as the blood is extracted to a plasma separator, conveying the visible components back into the body of a patient, feeding the plasma into a plasma adsorber to adsorb and eliminate some special substances in the plasma by using an adsorbent, and finally conveying the adsorbed plasma back again to the body of the patient. As far as a conventional plasma adsorber is concerned, the liquid flow such as plasma or a buffer solution passing through the adsorbent medium will generate a pressure difference thereby forming a column pressure, such that the filter part is subjected to a traction force along the direction of the liquid flow and tends to break of fall off. As a result, the adsorbent enters into the body of the patient along with the liquid flow and leads to a severe medical accident. <CIT> discloses an adsorbent packed column. The column includes: a casing for filling the adsorbent, the casing having a cylindrical shape, an open end, and a stepped portion; a cap fixed at an end of the casing; a filter positioned in contact with the stepped portion to prevent leakage of the adsorbent; and an O-ring disposed between the cap and the filter. <CIT> recites a low-density lipoprotein adsorption column. The adsorption column includes a container, and an adsorbent filled in the container. The container includes a blood inlet, a blood outlet, and a filter net that prevents the leakage of the adsorbent.

The disclosure provides a plasma adsorber and a packaging structure of an adsorbent of the plasma adsorber. The packaging structure of the adsorbent can prevent the filter part from being broken or falling off and prevent the adsorbent from entering into the body of the patient, such that potential safety hazards are eliminated. Thus, the plasma adsorber adopting the packaging structure of the adsorbent can complete the plasma adsorption process safely and reliably.

The following technical solution are adopted.

On the one hand, the disclosure provides a packaging structure of the adsorbent, comprising an adsorption body, a filter part and a first cover body; the adsorption body comprises an adsorption cavity which is used for accommodating the adsorbent and comprises an opening; the first cover body comprises an abutting surface disposed toward the filter part and is hermetically matchable with the opening to abut the abutting surface with the filter part; or the filter part is disposed on the abutting surface, and the filter part is attached to the abutting surface.

When the packaging structure of the adsorbent is used, the adsorption cavity is filled with the adsorbent which is packaged in the adsorption cavity by using the filter part, and the filter part and the adsorption body are kept relatively fixed by hermetic fit of the first cover body and the opening of the adsorption body. When the liquid flow flows through, the filter part can be kept stably, such that the adsorbent does not flow out along with flowing of the liquid flow reliably. Meanwhile, when the first cover body is hermetically matched with the opening of the adsorption body, the abutting surface of the first cover body is abutted against and attached to the filter part or the filter part is disposed on the abutting surface, such that the filter part is disposed by being attached to the abutting surface, and then the first cover body is hermetically matched with the opening of the adsorption body. Therefore, even though the filter part is subjected to the traction force along the direction of the liquid flow, the abutting surface further can support the filter part, such that the traction force to the filter part can be counteracted or alleviated, the filter part can be prevented from being broken or falling off and the adsorbent is prevented from entering into the body of the patient, such that potential safety hazards are eliminated.

The technical schemes are further described as follows.

In one of embodiments, the first cover body is further provided with a blood nozzle communicating with the adsorption cavity, and the abutting surface is provided with a diversion channel communicating with the blood nozzle. Thus, liquid flows in the parts on the abutting surface are guided to the blood nozzle via the diversion channel, such that the liquid flows can flow in or out smoothly via the blood nozzle.

In one of embodiments, the abutting surface is provided with at least two oppositely disposed diversion parts at intervals; adjacent two diversion parts are matched to form a runner, the runners communicate with each other to form the diversion channel, and the diversion part abuts against the filter part when the first cover body is hermetically matched with the adsorption body. Thus, the liquid flows are drained to the blood nozzle via the diversion channel formed by the runners communicating with each other.

In one of embodiments, the diversion part comprises a diversion seat disposed on the abutting surface and a diversion section disposed on the diversion seat. Thus, adjacent diversion seats are matched with corresponding adjacent diversion sections to form the runners.

In one of embodiments, the diversion part is used for abutting against the filter part and the diversion part is in linear contact with the filter part. Thus, the contact area between the diversion part and the filter part can be reduced and the risk that the liquid flows are left in a dead angle of a gap is reduced.

In one of embodiments, the packaging structure of the adsorbent further comprises a second cover body which is hermetically matched with the first cover body and seals the blood nozzle. Thus, the blood nozzle is sealed by using the second cover body and is prevented from being in contact with external air or foreign matters in a non-used state, thereby preventing the adsorbent from being polluted.

In one of embodiments, the first cover body comprises a first mounting cavity, a bottom wall of the first mounting cavity is provided with the blood nozzle and connectors oppositely disposed on the outer wall of the blood nozzle at intervals, and the connectors are matched with the outer wall of the blood nozzle to form a second mounting cavity where the second cover body is mounted. Thus, the second cover body and the first cover body can be matched to seal the blood nozzle.

In one of embodiments, the packaging structure of the adsorbent further comprises a sealing part, the sealing part is disposed in the adsorption cavity, and the sealing part, the first cover body and the filter part are matchable with each other to form a sealing structure for sealing the opening. Thus, the sealing performance of the packaging structure is further improved by using the sealing structure, so that the adsorbent is prevented from being polluted.

In one of embodiments, an outer wall of the first cover body is provided with a first locking portion, and an inner wall of the adsorption cavity is provided with a second locking portion in locking fit with the first locking portion. Thus, the first cover body can be prevented from rotating or axially playing relative to the adsorption body during use.

On the other hand, the disclosure discloses a plasma adsorber, comprising the packaging structure of the adsorbent.

When the plasma adsorber is used, the adsorption cavity is filled with the adsorbent which is packaged in the adsorption cavity by using the filter part, and the filter part and the adsorption body are kept relatively fixed by hermetic fit of the first cover body and the opening of the adsorption body. When the liquid flow flows through, the filter part can be kept stably, such that the adsorbent does not flow out along with flowing of the liquid flow reliably. Meanwhile, when the first cover body is hermetically matched with the opening of the adsorption body, the abutting surface of the first cover body is abutted against and attached to the filter part or the filter part is disposed on the abutting surface, such that the filter part is disposed by being attached to the abutting surface, and then the first cover body is hermetically matched with the opening of the adsorption body. Therefore, even though the filter part is subjected to the traction force along the direction of the liquid flow, the abutting surface further can support the filter part, such that the traction force to the filter part can be counteracted or alleviated, the filter part can be prevented from being broken or falling off and the adsorbent is prevented from entering into the body of the patient, such that potential safety hazards are eliminated. Therefore, the plasma adsorber can complete the plasma adsorption process safely and reliably.

As shown in <FIG>, in an embodiment, the disclosure provides a packaging structure of an adsorbent, comprising an adsorption body <NUM>, a filter part <NUM> and a first cover body <NUM>; the adsorption body <NUM> comprises an adsorption cavity <NUM> which is used for accommodating the adsorbent and comprises an opening <NUM>; the first cover body <NUM> comprises an abutting surface <NUM> disposed toward the filter part <NUM> and is hermetically matchable with the opening <NUM> to abut the abutting surface <NUM> with the filter part <NUM>; or the filter part <NUM> is disposed on the abutting surface <NUM>, and the filter part <NUM> is attached to the abutting surface <NUM>.

When the packaging structure of the adsorbent of the embodiment is used, the adsorption cavity <NUM> is filled with the adsorbent which is packaged in the adsorption cavity <NUM> by using the filter part <NUM>, and the filter part <NUM> and the adsorption body <NUM> are kept relatively fixed by hermetic fit of the first cover body <NUM> and the opening <NUM> of the adsorption body <NUM>. When the liquid flow flows through, the filter part <NUM> can be kept stably, such that the adsorbent does not flow out along with flowing of the liquid flow reliably. Meanwhile, when the first cover body <NUM> is hermetically matched with the opening <NUM> of the adsorption body <NUM>, the abutting surface <NUM> of the first cover body <NUM> is abutted against and attached to the filter part <NUM> or the filter part <NUM> is disposed on the abutting surface <NUM>, such that the filter part <NUM> is disposed by being attached to the abutting surface <NUM>, and then the first cover body <NUM> is hermetically matched with the opening <NUM> of the adsorption body <NUM>. Therefore, even though the filter part <NUM> is subjected to the traction force along the direction of the liquid flow, the abutting surface <NUM> further can support the filter part <NUM>, such that the traction force to the filter part <NUM> can be counteracted or alleviated, the filter part <NUM> can be prevented from being broken or falling off and the adsorbent is prevented from entering into the body of the patient, such that potential safety hazards are eliminated.

It should be noted that the filter part <NUM> of the embodiment can be a filter screen, a filter membrane or other elements capable of filtering the adsorbent, so that the adsorbent does not flow out of the adsorption cavity <NUM> along with the liquid flows. Meanwhile, a bore diameter of a filter hole of the filter part <NUM> is smaller than a grain size of adsorbent filler. In order to fill the adsorption cavity <NUM> with the adsorbent, a filler hole <NUM> communicating with the adsorption cavity <NUM> can be further formed in a side wall of the adsorption body <NUM>, and the filler hole <NUM> is sealed by using a sealing part such as a screw cap after filling. After the filter part <NUM> is disposed in the adsorption cavity <NUM> first, the first cover body <NUM> is hermetically matched with the opening <NUM>, such that the abutting surface <NUM> abuts against the filter part <NUM> to support the filter part <NUM>; the filter part <NUM> can be also directly disposed on the abutting surface <NUM>, for example, the filter part <NUM> is attached to the abutting surface <NUM> in a bonding or clamping mode, such that the filter part <NUM> can be supported by the abutting surface <NUM>, and then the first cover body <NUM>, together with the filter part <NUM>, is assembled with the adsorption body <NUM> and assembly and installation are achieved by hermetically matching the first cover body <NUM> with the opening <NUM>.

As shown in <FIG>, the filter part <NUM> is disposed in the adsorption cavity <NUM>, and the filter part <NUM> can be directly connected with the inner wall of the adsorption cavity <NUM>; and the filter part <NUM> can be also disposed in the adsorption cavity <NUM> after being disposed in a frame. In an embodiment, the filter part <NUM> is disposed as the filter screen, the filter screen is welded in the net rack <NUM> by way of rubber coating injection molding, ultrasonic or hot melting, and the inner wall of the adsorption cavity <NUM> is provided with the groove or the step groove where the net rack <NUM> is mounted. Thus, the filter part <NUM> can be simply and conveniently disposed in the adsorption cavity <NUM>.

As shown in <FIG> and <FIG>, the first cover body <NUM> is hermetically matched with the adsorption body <NUM>, which can be achieved by either a clamping fit manner or a threaded fit manner. In an embodiment, the outer wall of the first cover body <NUM> is provided with an external thread, an internal thread is correspondingly disposed on the inner wall of the adsorption cavity <NUM>, and the first cover body <NUM> is screwed into the adsorption cavity <NUM> by threaded fit of the external thread and the internal thread to achieve hermetic fit of the first cover body <NUM> and the adsorption body <NUM>, such that the abutting surface <NUM> of the first cover body <NUM> can be attached to the filter part <NUM> to provide a supporting force to the filter part <NUM>, thereby avoiding the problem that the filter part <NUM> is broken or falls off.

In an embodiment, the outer wall of the first cover body <NUM> is provided with the first locking portion (not shown), and the inner wall of the adsorption cavity <NUM> is provided with the second locking portion (not shown) in locking fit with the first locking portion. Thus, the first cover body <NUM> and the adsorption body <NUM> can be kept relatively fixed stably by means of locking fit between the first locking portion and the second locking portion to prevent the first cover body <NUM> from rotating or axially playing relative to the adsorption body <NUM> in a using process, such that the filter screen is prevented from moving, a gap between the filter screen and the adsorption cavity <NUM> is prevented, and the adsorbent is prevented from flowing out from the adsorption cavity <NUM>. Locking fit between the first locking portion and the second locking portion can be realized in a clamping manner, for example, the external thread is disposed on the outer wall of the first cover body <NUM>, the internal thread is correspondingly disposed on the inner wall of the adsorption cavity <NUM>, the first locking portion is conFIGured as a protrusion which protrudes toward the outer wall of the first cover body <NUM>, a groove where the protrusion extends in is further correspondingly formed in the inner wall of the adsorption cavity <NUM>, and when the first cover body <NUM> is screwed into the adsorption cavity <NUM> and the abutting surface <NUM> abuts against the filter part <NUM>, the protrusion is clamped into the groove, thereby achieving locking between the first cover body <NUM> and the adsorption body <NUM>; and when the first cover body <NUM> is screwed out of the adsorption cavity <NUM>, the protrusion is separated from the groove.

As shown in <FIG> and <FIG>, based on any one embodiment, the first cover body <NUM> is further provided with the blood nozzle <NUM> communicating with the adsorption cavity <NUM>, and the abutting surface <NUM> is provided with the diversion channel <NUM> communicating with the blood nozzle <NUM>. Thus, the liquid flows in the adsorption cavity <NUM> can be uniformly drained to the blood nozzle <NUM> via the diversion channel <NUM>, thereby reducing the cavity volumes at two ends of the adsorption body <NUM> and distributing the liquid flows well. The liquid flows can flow through the adsorbent in the adsorption cavity <NUM> uniformly without dead angles.

The diversion channel <NUM> can be formed by either forming the division groove in the abutting surface <NUM> toward the abutting surface <NUM> or arranging a partition plate outside the abutting surface <NUM> on the abutting surface <NUM>. In an embodiment, the abutting surface <NUM> is provided with at least two diversion parts <NUM> oppositely disposed at an interval, adjacent two diversion parts <NUM> are matched to form a runner, the runners communicate with each other to form a diversion channel <NUM>, and the diversion part <NUM> abuts against the filter part <NUM> when the first cover body <NUM> is hermetically matched with the adsorption body <NUM>. Thus, the runner is formed between at least two diversion parts <NUM> protruding out of the abutting surface <NUM>, and the runners communicate with each other to drain the liquid flows uniformly to the blood nozzle <NUM>. Meanwhile, the diversion part <NUM> is in contact with the filter part <NUM>, thereby providing a supporting force to the filter part <NUM>.

in an embodiment, the abutting surface <NUM> is provided with four annularly disposed diversion parts <NUM> at intervals, each diversion part <NUM> is disposed around the blood nozzle <NUM> and abuts against the filter part <NUM>, the adjacent two diversion parts <NUM> are matched to form three runners, and each runner is provided with the notches <NUM>, such that the three runners communicate one another to form the diversion channel <NUM> communicating with the blood nozzle <NUM>. Thus, the three runners distribute the liquid flows uniformly and guide the flow liquids to the blood nozzle <NUM>, and thereby, the liquid flows flow smoothly.

In an embodiment, the diversion part <NUM> comprises the diversion seat <NUM> disposed on the abutting surface <NUM> and the diversion section <NUM> disposed on the diversion seat <NUM>. Thus, the adjacent two diversion seats <NUM> and the adjacent two diversion sections <NUM> form runners, thereby draining the liquid flows. Further, a projection of the diversion section <NUM> on the abutting surface <NUM> falls into a projection of the diversion seat <NUM> on the abutting surface <NUM>, i.e., a gap between the adjacent two diversion seats <NUM> is smaller than a gap between the adjacent two diversion sections <NUM>, such that a flow rate of a part, close to diversion seat <NUM>, of the liquid flow is higher than that of a part, close to the diversion section <NUM>, of the liquid flow, such that the liquid flow can flush the bottom of the runner, thereby preventing the liquid flow from being blocked in the runner.

In an embodiment, the diversion part <NUM> is used for abutting against the filter part <NUM> and the diversion part <NUM> is in linear contact with the filter part <NUM>. Thus, in order to decrease the contact area between the diversion part <NUM> and the filter part <NUM> and prevent the liquid flow from being left in a contact gap between the diversion part <NUM> and the filter part <NUM>, such that the liquid flow can flow out or in smoothly. A contact part between the diversion part <NUM> and the filter part <NUM> is disposed in a curved surface or a cambered surface, for example, the diversion section <NUM> is disposed cylindrically, such that the diversion part <NUM> is in linear contact with the filter part <NUM>.

Thus, the second cover body <NUM> is mounted in the second mounting cavity <NUM>, thereby isolating the blood nozzle <NUM> hermetically by the second cover body <NUM>.

As shown in <FIG> and <FIG>, in an embodiment, the connector <NUM> is disposed as a flange, the first thread is disposed on the outer wall, facing the second mounting cavity <NUM>, of the flange, the second cover body <NUM> is disposed as a first sealing body <NUM> provided with the first sealing cavity <NUM>, the outer wall of the first sealing body <NUM> is provided with a second thread in threaded fit with the first thread, and it is only needed to screw the first sealing body <NUM> into the second mounting cavity <NUM>, such that the blood nozzle <NUM> extends into the first mounting cavity <NUM> to seal the blood nozzle <NUM>.

Further on, a seal ring can be further additionally disposed between the flange and the second sealing cavity <NUM> or a space between the flange and the second sealing cavity <NUM> can be further filled with a sealing medium, such that the blood nozzle <NUM> can be further prevented from being polluted.

As shown in <FIG>, based on any one embodiment, the reinforcing rib <NUM> is further disposed on the inner wall of the first mounting cavity <NUM>. Thus, the structural performance of the first cover body <NUM> can be improved and it is further convenient to screw the first cover body <NUM> into the adsorption cavity <NUM>.
