Patent Description:
Generally, a patient who has difficulty in spontaneous breathing relies on a ventilator to breathe. In addition, medication may be prescribed according to a decision of a doctor, and the medication may be included in air conditioned in a ventilator and then provided to a patient. Various medications may be used according to a patient's physical condition and, for example, medication that helps a lung function may be used when a patient's lung function is bad.

Conventionally, in order to inject medication, a T-tube is disposed on a tube that is connected to a mask or a mouthpiece from a ventilator, a medication case is mounted on one side of an inlet of the T-tube, and the medication is injected into the medication case. In addition, an open portion of the medication case is covered with a lid so as to prevent contamination.

The T-tube is provided with a medication vaporizing apparatus, and the medication is vaporized using the medication vaporizing apparatus and the vaporized medication is included in conditioned air, and then the vaporized medication is provided to a patient.

However, as described above, a conventional technology has problems such as contamination, labor, cost, and so on. More specifically, although a timing of medication injection varies according to a prescription of a doctor, the timing may be set such that medication is injected approximately two to four times a day, and the lid is then removed and closed each time. In this process, there are problems in that a time for which the medication case is exposed is prolonged inevitably, the possibility of contamination may increase, there is the hassle of opening and closing the lid, and the cost increases since a tube replacement cycle is fast as the possibility of contamination is high.

Meanwhile, the ventilator is configured to purify air, to heat the air to the temperature similar to body temperature, to appropriately adjust the pressure of the air, and to provide the air that is conditioned to a patient. However, the temperature of the conditioned air may be changed while the conditioned air is moved along the tube, and there is a problem that the air having a low temperature is provided to a patient's respiratory organs.

Some prior art medication injection structures for use in ventilation systems are known from the documents <CIT>, <CIT>, <CIT> and <CIT>.

The document <CIT>, for example, discloses a drug administering endotracheal respiration system for administering vital life-saving drugs into the lungs of a victim while maintaining the flow of life-supporting gas thereto via ventilation apparatus comprising in combination: a gas supply; a tube for establishing gas flow exchange between the lungs of the victim and the gas supply, the tube having a proximal end and a distal end for insertion into the trachea of the victim; and a connector for coupling the proximal end of the tube to the gas supply, the connector being formed as a cylinder with a gas input end and a gas discharge end and a linear main axial passageway therebetween, the connector having a first port adapted for injecting vital life-saving drugs in liquid form into the passageway and then into the distal end of the tube intermixed with the gas, the first port having a portion integrally formed with the connector and a portion separable therefrom, the connector further having a second port adapted for injecting vital life-saving drugs in liquid form into the passageway and then into the distal end of the tube intermixed with the gas, the second port having a portion integrally formed with the connector and a portion separable therefrom, the main axial passageway adapted for atomizing and intermixing of the flow of life-saving drugs with the life-supporting gas.

Hereinafter, referring to <FIG>, a ventilator medication injection structure according to an embodiment of the present disclosure will be described. <FIG> are views illustrating a ventilator medication injection structure according to an embodiment of the present disclosure, in which <FIG> is a view illustrating an external appearance of the ventilator medication injection structure, <FIG> is an exploded cross-sectional view in which elements of the ventilator medication injection structure are disassembled, and <FIG> is a cross-sectional view in which the elements are assembled. <FIG> is a view illustrating a cover in the ventilator medication injection structure according to an embodiment of the present disclosure.

A ventilator medication injection structure according to an embodiment of the present disclosure may include a T-tube <NUM>, a cover <NUM>, and a packing closure <NUM>.

As illustrated in <FIG>, in the T-tube <NUM>, a tube body extends from an inlet <NUM> to an outlet <NUM>, and a branch tube <NUM> is formed on one side of the tube body.

As illustrated in <FIG>, in the cover <NUM>, a first tube body <NUM> is formed below a flange <NUM>, and a second tube body <NUM> is formed inside the first tube body <NUM> such that the second tube body <NUM> penetrates the flange <NUM>. A male screw <NUM> is formed on an outer peripheral surface of the second tube body <NUM>.

As illustrated in <FIG>, the first tube body <NUM> is fitted and assembled to the branch tube <NUM>.

In the packing closure <NUM>, a third tube body <NUM> is formed at a center of a body <NUM> such that the third tube body <NUM> is fitted inside the second tube body <NUM>. A fourth tube body <NUM> is formed on an outside of the third tube body <NUM>, and a female screw <NUM> is formed on the fourth tube body <NUM>. As illustrated in <FIG>, the female screw <NUM> is fastened to the male screw <NUM>.

In addition, a pocket <NUM> is formed inside the body <NUM>, and the pocket <NUM> may be densely filled with a packing <NUM>.

The packing <NUM> has elasticity. More specifically, the packing <NUM> may be formed of soft rubber. Accordingly, when a syringe needle pierces the packing <NUM>, the syringe needle may penetrate the packing <NUM>. Furthermore, when the syringe needle is pulled out, a piercing made by the syringe needle is immediately filled by the elasticity of the packing <NUM>.

Medication may be injected inside the T-tube <NUM> with a syringe by piercing the packing <NUM> with the syringe needle and passing the syringe needle through the third tube body <NUM>.

In the ventilator medication injection structure according to an embodiment of the present disclosure, medication is capable of being injected into the T-tube <NUM> while a syringe needle is inserted into the packing <NUM>, and the packing <NUM> is configured such that a space through which the syringe needle was passed is blocked when the syringe needle is removed from the packing <NUM>, so that an inner portion of the T-tube <NUM> is capable of being fundamentally prevented from being exposed.

Accordingly, in the ventilator medication injection structure according to an embodiment of the present disclosure, the exposure of the inner portion of the T-tube <NUM> that serves as a medication case may be minimized or the medication case may be fundamentally blocked from being exposed, so that contamination of the medication case is prevented. Furthermore, a patient can live in a more strictly clean environment.

In addition, by preventing the exposure of the inner portion of the T-tube <NUM>, an entire section of the tube connected from the ventilator to a mask or a mouthpiece may be strictly prevented from being exposed to the outside.

Meanwhile, as illustrated in <FIG>, the first tube body <NUM> may be provided in a tapered shape having a narrow lower side, and may be formed of a material having elasticity. Accordingly, as illustrated in <FIG> and <FIG>, when the ventilator medication injection structure in a disassembled state is assembled, the cover <NUM> is capable of being fitted and assembled in a straight direction without rotating the cover <NUM>.

Since the first tube body <NUM> is provided in the tapered shape, the first tube body <NUM> is easily assembled due to a large diameter difference at the beginning of assembly when the first tube body <NUM> is inserted into the branch tube <NUM>, and the first tube body <NUM> may be assembled more and more tightly as the assembly progresses.

In addition, since the first tube body <NUM> has an elastic property, the first tube body <NUM> is in close contact with an entire of inner peripheral surface of the branch tube <NUM>, so that contaminants from the outside may be fundamentally prevented from being introduced into the inner portion of the T-tube <NUM>.

On the other hand, as illustrated in <FIG>, a power connector <NUM> to which an external power source is capable of being connected is disposed on one side of the T-tube <NUM>.

As illustrated in <FIG> and <FIG>, a heating wire <NUM> may be disposed inside the T-tube <NUM>, the heating wire <NUM> may generate heat by being connected to the external power source, and air conditioned as described above may be heated by the heat.

Therefore, in the ventilator medication injection structure according to an embodiment of the present disclosure, even when the temperature of conditioned air to be provided to a patient is low, the conditioned air is capable of being reheated, and the patient can always breathe the conditioned air at an appropriate temperature.

Although an exemplary embodiment of the present disclosure was described above with reference to the accompanying drawings, those skilled in the art would understand that the present disclosure may be implemented in various ways without departing from the scope of the prevent disclosure.

Therefore, it should be understood that the embodiment described above is not limitative, but only an example in all respects, the scope of the present disclosure is expressed by claims described below, not the detailed description, and it should be construed that all of changes and modifications achieved from the meanings and scope of claims and equivalent concept are included in the scope of the present disclosure.
