Description

Technical Field

[0001] The utility model relates to the field of anesthesia atomization, in particular to an anesthesia atomization medicine cup. Background Art

[0002] Patients undergoing general anesthesia may suffer from airway damage caused by endotracheal intubation or laryngeal mask insertion, which may lead to coughing, pain, and even airway spasm. For some asthma patients, airway irritation may induce asthma, seriously affecting the patient's comfort and even threatening their life. Pediatric airway surgery may cause severe choking and coughing, and young children are more likely to suffer from airway spasm, with serious consequences and endangering their life. The commonly used clinical solution is postoperative nebulized inhalation of hormones and bronchodilators to relieve the symptoms. In order to prevent or treat this complication, we need to nebulize inhaled drugs during general anesthesia to minimize adverse reactions, improve comfort, and ensure patient safety. There is currently no nebulizer device suitable for general anesthesia on the market, so this device was developed to meet the nebulization requirements during anesthesia.

[0003] Existing patent documents have proposed a method of combining atomization and humidification by modifying the atomizer itself. For example, a medical anesthesia atomizer disclosed in publication number CN114748759A has a relatively complex internal structure and is difficult to clean, making it unsuitable for reuse and easily leading to contamination of the drug solution and even cross infection. Utility Model Content

[0004] In view of the above situation, in order to overcome the defects of the existing technology, the utility model adopts an anesthetic atomization medicine cup to solve the problem of difficulty in achieving synchronous atomization during anesthesia in the existing technology and the airway dryness caused by the existing atomization process.

[0005] The technical solution is to provide an anesthetic atomization medicine cup, comprising a medicine cup, which is a cylindrical shell with openings at both ends, a nozzle fixed at the lower opening of the medicine cup, and a vertical tube provided at the upper opening of the medicine cup. The lower end of the vertical tube is placed in the medicine cup cavity and the outer edge surface of the upper end is connected to the upper opening of the medicine cup by a thread. A one-way valve is provided at the opening position of the upper end of the vertical tube, and the one-way valve can only take in air in one direction to the lower side of the vertical tube. The middle part of the lower end of the vertical tube is located above the upper opening of the nozzle and is fixed with a spacer through a connecting rod. The lower end of the vertical tube is located on the outer side of the nozzle and is fixed with a sleeve, and the sleeve and the nozzle have a gap fitted. An air outlet and an air inlet are respectively provided on the left and right sides of the outer edge surface of the medicine cup, and a humidifying chamber connected to the air inlet is provided at the outer end of the air inlet. The right end of the humidifying chamber is open and a cover is provided at the opening position. The cover can open or close the humidifying chamber, and an air inlet pipe is fixed in the middle of the cover. A water-absorbing sponge is provided in the middle of the humidifying chamber, which divides the humidifying chamber into left and right parts.

[0006] Furthermore, the cover plate is connected to the right side opening of the humidification chamber through a threaded connection, a retaining ring is provided on the inner wall of the humidification chamber on the left side of the water-absorbing sponge, and a pressure ring is provided on the right side of the water-absorbing sponge. The pressure ring is fixedly connected to the cover plate through a connecting rod. When the cover plate blocks the right side opening of the humidification chamber, the pressure ring and the retaining ring can fix the position of the water-absorbing sponge.

[0007] Furthermore, the one-way valve on the vertical pipe is a hinged plate, which can block the upper opening of the vertical pipe when it remains in a horizontal state. A block is provided at the upper end of the hinged plate, which can prevent the hinged plate from swinging upward from the horizontal. A torsion spring is provided at the hinged position of the hinged plate, which keeps the hinged plate in a horizontal state at all times.

[0008] Furthermore, the thickness of the middle portion of the water-absorbing sponge is greater than the thickness of the outer edge, and a support ring is fixed to the outer edge surface of the water-absorbing sponge, and the retaining ring and the pressure ring are in contact with the left and right end surfaces of the support ring respectively.

[0009] A transfer tube is fixed at the opening position on the lower side of the medicine cup, and a one-way valve is arranged in the transfer tube. The one-way valve allows the transfer tube to only take air into the medicine cup in one direction.

[0010] Compared with the prior art, the present invention has the following advantages:

[0011] 1. Connecting the atomizer cup and the humidifier in series can provide continuous drug atomization treatment to the patient while anesthetizing the patient. This simplifies the anesthesia and atomization treatment steps and ensures the humidity of the atomization airflow, giving the patient a better treatment experience.

[0012] 2. It solves the existing problem of difficulty in performing anesthesia and atomization at the same time, and avoids infection caused by the contact of the drug solution with the outside world during the replacement of anesthesia and atomization equipment;

[0013] 3. The easy-to-disassemble vertical pipe and cover facilitate the quick replacement of the atomizer component and the water-absorbing sponge, making it easier to deal with emergencies during surgery;

[0014] 4. By setting the water-absorbing sponge with a thickness in the middle greater than that at the outer edge, the humidification effect can be ensured to be more lasting;

[0015] 5. By installing a one-way valve in the transfer tube, the pressurized gas from the anesthesia machine can be prevented from entering the nebulizer in reverse. BRIEF DESCRIPTION OF THE DRAWINGS

A one-way valve is provided at the upper opening of the vertical pipe 3. The one-way valve can only intake air in one direction to the lower side of the vertical pipe 3. The middle of the lower end of the vertical pipe 3 is located above the upper opening of the nozzle 2 and is fixed with a spacer 4 through a connecting rod. The lower end of the vertical pipe 3 is located A sleeve 5 is fixed on the outside of the nozzle 2, and the sleeve 5 is loosely fitted with the nozzle 2; an air outlet 6 and an air inlet 7 are respectively provided on the left and right sides of the outer edge of the medicine cup 1, and a humidifying chamber 8 connected to the air inlet 7 is provided at the outer end of the air inlet 7. The right end of the humidifying chamber 8 is open and a cover plate 9 is provided at the opening position. The cover plate 9 can open or close the humidifying chamber 8. An air inlet pipe 10 is fixed in the middle of the cover plate 9, and a water-absorbing sponge 11 is provided in the middle of the humidifying chamber 8. The water-absorbing sponge 11 divides the humidifying chamber 8 into two parts, left and right.

[0022] The cover plate 9 is connected to the right side opening of the humidification chamber 8 through a threaded connection. A retaining ring 12 is provided on the inner wall of the humidification chamber 8 on the left side of the water-absorbing sponge 11. A pressure ring 13 is provided on the right side of the water-absorbing sponge 11. The pressure ring 13 is fixedly connected to the cover plate 9 through a connecting rod. When the cover plate 9 blocks the right side opening of the humidification chamber 8, the pressure ring 13 and the retaining ring 12 can fix the position of the water-absorbing sponge 19.

[0023] The one-way valve is a hinged plate, which can block the upper opening of the vertical pipe 3 when it remains in a horizontal state. A block is provided at the upper end of the hinged plate, which can prevent the hinged plate from swinging upward from the horizontal. A torsion spring is provided at the hinged position of the hinged plate, which keeps the hinged plate in a horizontal state at all times.

[0024] The thickness of the middle portion of the water-absorbing sponge 11 is greater than the thickness of the outer edge, and a support ring 14 is fixed to the outer edge of the water-absorbing sponge 11 , and the retaining ring 12 and the pressure ring 13 are in contact with the left and right end surfaces of the support ring 14 respectively.

[0025] A transfer tube 15 is fixed to the lower opening of the medicine cup 1 , and a one-way valve is provided in the transfer tube 15 , so that the one-way valve allows the transfer tube 15 to only allow air to flow into the medicine cup in one direction.
