An integrated rhinitis recovery and care device having a magnetization function comprises a bottle body, a medicine liquid nozzle (1), a medicine liquid duct (2), a recycle duct (3), a pump-out mechanism (4), and a nasal cavity bionic plate (5). The bottle body comprises a medicine liquid chamber (6) and a recycle chamber (7). A liquid leakage hole (8) is formed in the lower end of the nasal cavity bionic plate (5), and a nose wing-shaped protrusion (9) is disposed at the upper end of the nasal cavity bionic plate (5). The pump-out mechanism (4) is in communication with the medicine liquid chamber (6) by means of the medicine liquid duct (2), and the medicine liquid nozzle (1) is in communication with the medicine liquid duct (2) by means of the pump-out mechanism (4); the liquid leakage hole (8) is in communication with the recycle chamber (7) by means of the recycle duct (3), and the recycle duct (3) is in communication with the liquid leakage hole (8) by means of a second liquid one-way valve(12). A magnet (10) used for cutting medicine liquid molecules by magnetic force is disposed at the bottom of the medicine liquid chamber (6). The device is convenient to carry and use, and can enhance the medicine liquid absorption effect by cutting medicine liquid molecules by magnetization and can enhance the medicine liquid absorption effect by hot gas.
A: A medical device, the medical device comprising a joint (1), a catheter (2), and a guide wire (3). The medical device further comprises: an elastic part (4) sleeved on the other end of the guide wire (3); and a protruding part (5) sleeved on the outer circumference of the guide wire (3). The protruding part (5) is connected between the elastic part (4) and the catheter (2); the diameter of the protruding part (5) is larger than the diameters of the catheter (2) and the elastic part (4). When the catheter (2) is drawn inside a blood vessel, the protruding part (5) can not only prevent damage to the medical device, but also effectively lower the risk in catheter-directed thrombolysis, and can also break and clean thrombi in advance, so as to increase the contact area of a liquid medicine during medication, thereby accelerating absorption of the liquid medicine and improving treatment effect.
B: A medication preparation device and method for a vial. The device comprises a control system and a double head syringe (2) provided on a base (1). A catheter I (22) and a catheter II (23) connected to the syringe (2) are connected to a needle I (3) for being inserted into a vial (01) and a needle II (4) for being inserted into an infusion bag (02), respectively. The catheter I (22) is provided with a clasp member I (5). The catheter II (23) is provided with a clasp member II (6). The control system is communicatively connected to a linear reciprocating motion mechanism I (11), the clasp member I (5), and the clasp member II (6). Compared with the low efficiency of the method in the prior art of manually holding a syringe to suck the medicinal liquid or powder contained in a vial, and then manually holding an infusion bag to insert the syringe into the infusion bag and inject the medicinal liquid therein, and the potential danger of the method in the prior art to a medical staff who operates, the device is simple in structure, occupies small space, and is simple to operate; the invention automates and facilitates preparation and injection of the medicinal liquid or powder in the vial, effectively avoids backflow of the medicinal liquid, effectively reduces the labor intensity, has high medication preparation efficiency, and is secure.
C: Disclosed is a nasal cavity irrigation device, comprising: a water supply assembly, a catheter (7) used to transfer cleaning fluid and a nozzle (2). An end of the catheter (7) for fluid flowing in is connected to the water supply assembly and an end for fluid flowing out is connected to the nozzle (2). A camera module (3) is located at the front end of the nozzle (2), and the camera module (3) is connected to a display assembly though a data channel (6). The camera module (3) located at the front end of the nozzle of the nasal cavity irrigation device can achieve the effect of visualization. During use, a patient is able to irrigate the nasal cavity accurately and effectively by themselves under the guidance of the images captured by the camera module (3), and flush out the foreign bodies in the nasal cavity thoroughly. The nasal cavity irrigation device is simple in structure, convenient to carry, and suitable for self-irrigation of the nasal cavity by patients at home or while travelling, thereby decreasing the cost of treatment and nurses.
D: A manual multi-bottle infusion apparatus. Same is provided with a manual medicine-changing apparatus (7). The manual medicine-changing apparatus (7) comprises multiple penetrating connectors (8) and a medicine-changing valve (9). The medicine-changing valve (9) comprises a valve base (10) and a valve core (11). The valve base (10) is provided with a sliding cavity (12), a solution-collecting chamber (13), and multiple solution-infusing connectors (14). Each solution-infusing connector (14) corresponds to a solution outlet (15). The valve core (11) is provided with a solution-guiding hole (16), multiple orientation positioning holes (17) corresponding to every solution-infusing connector (14), and a pusher (22). The pusher is used for pushing the valve core (11). The solution-guiding hole (16) of the valve core (11) is utilized to connect the different solution-infusing connectors (14) to the solution outlets (15) corresponding thereto. When a patient needs infusion of multiple medicinal solutions, a nurse connects multiple medicinal solution bottles (23) to the manual medicine-changing apparatus (7). When the medicinal solution of the first medicinal solution bottle (23) is depleted, the patient or an accompanying person presses with hand the pusher (22) of the manual medicine-changing apparatus (7) to connect the medicinal solution of the next medicinal solution bottle (23) to a solution-infusing apparatus (1), thus solving the problem of nurse shortage.
