Technical Field

[0001] The present application relates to the field of anesthesia devices, and in particular to an inhalation anesthesia device. Background Art

[0002] Patients with high risk of difficult airway often need to be intubated while maintaining spontaneous breathing and awake. During this process, the throat and tracheal mucosal surface need to be fully anesthetized. The key to the anesthesia operation of the throat and tracheal mucosal surface is the atomization and delivery of local anesthetics.

[0003] Existing anesthetic drug atomizers usually require a large amount of local anesthetic drugs to be poured into the glass bottle of the anesthesia atomizer in advance, so that the liquid anesthetic can be mixed with the gas source gas in the atomization airflow pipeline, and then transported to the atomization nozzle to act on the patient's throat and tracheal mucosa. However, in the process of pouring the local anesthetic drug into the glass bottle of the anesthesia atomizer, there is a certain risk of contamination, and it is also easy to cause waste of local anesthetic drugs, and it is impossible to accurately control the dosage of the drug.

[0022] The preferred embodiments of the present application are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present application and are not used to limit the present application.

[0023] The meaning of "inside" and "outside" mentioned in this application refers to the direction from the outer wall of the bottle to the center of the internal medicine containing space of the anesthetic agent containing bottle as inside, and vice versa as outside; it is not a specific limitation on the device mechanism of this application.

[0024] The meaning of "left and right" in this application refers to that when the user is facing the universal bottle cap, the direction from the air source to the atomizing nozzle is right, and the opposite direction is left, rather than a specific limitation on the device mechanism of this application.

[0025] The term “connection” as used in this application may mean a direct connection between components or an indirect connection between components via other components.

[0026] The meaning of "up" and "down" in this application refers to that when the user is facing the universal bottle cap in a connected state, the direction from the bottom of the siphon tube to the connecting tube interface is up, and the opposite direction is down, rather than a specific limitation on the device mechanism of this application.

[0027] The inhalation anesthesia device provided in this application can be used according to Figure 1 The method shown is arranged between the gas source and the atomizing nozzle, directly connected to the bottle of anesthetic agent, using the nozzle and the nozzle to form an atomizing structure, connecting the siphon tube to the liquid inlet so as to directly extract the agent from the opening of the medicine bottle and transport it to the nozzle for atomization under the action of the airflow, thereby reducing the potential pollution risk.

[0028] Specifically, the present application utilizes a universal bottle cap 1 to connect an anesthetic agent bottle, and a connecting pipe 5 connecting an atomizing nozzle and an air source is provided on the top of the universal bottle cap 1. The connecting pipe 5 is provided through the interior of the universal bottle cap, and is connected to a siphon tube 4 at the bottom of the universal bottle cap, forming a three-way structure. The siphon tube 4 is longitudinally provided in the universal bottle cap, and is used to connect an anesthetic agent containing bottle, and extends from the bottom of the universal bottle cap to the bottom of the anesthetic agent containing bottle to obtain the agent.

[0029] In order to adapt to anesthetic bottles of different calibers, the present application connects an elastic airbag 6 under the universal bottle cap, and arranges a plurality of hard fan-shaped pieces 2 on the side walls of the elastic airbag 6 to achieve a sealed connection with the medicine bottle through the threads 3 arranged on the fan-shaped pieces 2.

[0030] Specifically, when the universal bottle cap 1 is connected to the anesthetic agent containing bottle, the elastic airbag 6 can be inflated to expand through the inflation port arranged on the top of the bottle cap and interconnected with the elastic airbag 6, thereby utilizing the deformation of the elastic airbag 6 to drive the sector piece 2 to fit tightly against the bottle mouth of the anesthetic agent containing bottle, so that the thread 3 can be tightly overlapped with the bottle mouth structure of the anesthetic agent containing bottle to achieve sealing, or, when the thread spacings of the two match each other, directly tightened with the thread of the bottle mouth of the medicine bottle to achieve a sealed connection.

[0031] The connecting tube 5 of the present application can be a hard tube interface protruding from the universal bottle cap, and can be connected to the gas source and the nozzle through a connecting hose, or can be directly connected to the gas source through an integrally formed hose. The gas from the gas source is mixed with the liquid in the siphon input pipe to form a gas-liquid mixture, and the mixture enters the atomizing nozzle through the pipe to atomize and output the gas-liquid mixture through the atomizing nozzle. The atomizing nozzle can directly adopt the existing detachable nozzle structure, or it can be integrated into the end of the hose of the present application.

[0032] In the present application, the gas source of the inhalation anesthesia device can be a small fan, a rubber balloon, etc.; when medical conditions permit, a conventional ventilator or an existing oxygen supply pipeline in the ward or other medical equipment that can generate pressurized airflow can be used to continuously or intermittently supply gas to the atomizing nozzle.

[0033] In order to match the thread of the anesthetic bottle mouth, in the present application, the thread 3 structure between each sector 2 can be connected layer by layer. Figure 2 In this way, a thinner side wall is provided between each sector piece 2, so that the elastic airbag 6 can expand outwards between the sector pieces 2 and fit the side wall of the medicine bottle to assist in sealing. In this process, since the airbag wall between the sector pieces 2 is thin, it can provide a certain deflection amount for each sector piece 2 in accordance with the thread direction, so that the thread on the sector piece 2 can be slightly tilted so as to be adjusted to a state matching the rotation angle of the thread on the medicine bottle.

[0034] For medicine bottles without threads, the thinner airbag sidewalls of each sector piece 2 can be closely attached to the sidewalls of the bottle mouth, and the airbag can be directly used to achieve sealing. At this time, the threads on each sector piece 2 can fit the bottle mouth accordingly, providing greater friction, so that the universal bottle cap 1 of the present application can be more tightly connected to the bottle mouth.

[0035] For medicine bottles that are sealed by internal threads, the present application generally arranges the sector pieces 2 circumferentially on the outer wall of the elastic airbag 6, arranges the sector pieces around the universal bottle cap, and arranges the threads 3 as external threads protruding from the outer wall of the sector pieces 2, so that the external threads can cooperate with the internal threads of the bottle mouth of the anesthetic agent containing bottle. In the case where the thread pitches of the two do not match, the sector pieces, threads, and the outer wall of the elastic airbag 6 and the inner wall of the bottle mouth of the anesthetic agent containing bottle can also be directly abutted against each other to achieve sealing.

[0036] In order to facilitate the guidance of the threads on each sector piece 2, the present application also preferably extends the threads 3 on the above-mentioned sector pieces 2 outward along the circumference of the universal bottle cap, so that the ends of each thread 3 respectively exceed the boundary of the sector piece 2, and thins its ends to provide guidance along the bottle mouth threads, so that each layer of threads on the bottle cap can smoothly enter the gap between the bottle mouth threads to achieve sealing.

[0037] For medicine bottles that are sealed by external threads, the present application generally adds a circle of larger diameter limit ring at the bottom of the universal bottle cap, so that the limit ring can surround the outer circumference of the mouth of the medicine bottle and provide support at the bottom of the universal bottle cap to limit the inflation deformation direction of the elastic airbag 6. The elastic airbag 6 is arranged in the limit ring, so that the outer wall of the airbag can fit with the inner circumference of the limit ring when inflated to limit the outward expansion of the airbag. At this time, the fan-shaped piece 2 can be arranged circumferentially on the inner wall of the elastic airbag 6 and arranged around the universal bottle cap. Therefore, the present application can achieve sealing by tightening the internal thread protruding from the inner wall of the fan-shaped piece 2 and the external thread of the mouth of the anesthetic agent holding bottle, or, when the spacing between the two does not match, directly use the elastic airbag 6 to achieve sealing by fitting the internal thread with the outer wall of the mouth of the anesthetic agent holding bottle.

[0038] In this state, since the radius of the bottle body thread is uncertain, it is preferred that the threads 3 on each sector piece 2 are respectively contracted along the center of the universal bottle cap circumferential sector piece 2, and the ends of each thread 3 are set not to exceed the boundary of the sector piece 2. Therefore, when the radius of the bottle body thread is small, the gaps formed by the ends of the threads can be further contracted inward to form a smaller inner diameter structure. At this time, the bottle cap can be fixed to the bottle body only by connecting the threads in the middle of the sector structure.

[0039] In this state, the ends of the threads 3 between the sector pieces 2 can also be slightly thinned to form transition surfaces 31, so that the threads can be guided by the transition surfaces into the gaps between the thread structures of the bottle mouth, and seal can be achieved with the expansion of the airbag.

[0040] In order to match the different telescopic states of the airbag, the present application preferably sets the transition surface 31 of the end of the thread 3 between two adjacent sector pieces 2 to have mutually matching and mutually parallel inclination angles. In this way, the adjacent threads can be plugged into each other to adapt to the smaller diameter of the medicine bottle.

[0041] In specific practice, the transition surface 31 at the end of the thread 3 between the sector pieces 2 is generally set to be wedge-shaped, or set to be Figure 1 In the manner shown, the transition is made by tilting the side with a lower spiral position upward.

[0042] In order to prevent the air bag from being deflated and affecting the seal, the inhalation anesthesia device described in the present application is further provided with an air valve on the inflation port of the elastic air bag 6 to realize inflation and deflation control.

[0043] Therefore, when the medicine bottle needs to be replaced, the present application can directly deflate the airbag to make it thinner and cancel the seal on the existing bottle body. After the siphon is inserted into the replaced medicine bottle, the air can be inflated through the inflation port accordingly, so that the universal bottle cap is sealed and connected to the new medicine bottle again.

[0044] Those skilled in the art can understand that the above description is only a preferred embodiment of the present application and is not intended to limit the present application. Although the present application is described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions recorded in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
