Description

Technical Field

[0001] The present disclosure belongs to the field of medical devices, and particularly relates to an intensive care ventilator. Background Art

[0002] As a commonly used rescue method in first aid, endotracheal intubation is one of the most widely used, effective, and rapid means in airway management, and is a basic skill that medical staff must master proficiently. Literature reports that the incidence of difficult endotracheal intubation is between 1.5% and 13%, and difficult intubation is more likely to occur in suboptimal environments outside the operating room, such as the emergency room, intensive care unit (ICU), patient ward, or even outside the hospital. Nasotracheal intubation under local anesthesia is the most effective method for dealing with difficult airways;

[0003] For example, Chinese Patent with the publication number CN210020718U discloses an oropharyngeal airway with a sputum suction function, which overcomes the problems that still need to be improved in the clinical management of the oropharyngeal airway. The utility model includes an oropharyngeal airway tube, a sputum suction tube, a bite block, a protruding flange, and a flange fixing hole. A sputum suction tube is provided on the side wall of the oropharyngeal airway tube. The oropharyngeal airway tube is divided into an external interface part, a bite block part, an oral cavity part, and a pharyngeal cavity part. The sputum suction tube is divided into an external interface part, an oral cavity part, and a pharyngeal cavity part. A ventilator connection port is provided at the external interface part of the oropharyngeal airway tube. A bite block is sleeved on the inner tube wall of the bite block part. Multiple ventilation holes are provided in the pharyngeal cavity part. A suction device connection port is provided at the external interface part of the sputum suction tube. Multiple saliva drainage holes are provided in the pharyngeal cavity part. A protruding flange is provided at the joint of the external interface part and the bite block part of the oropharyngeal airway tube. This technology sucks away the sputum and saliva of the patient through the saliva drainage holes in the pharyngeal cavity part of the sputum suction tube, avoiding the phenomena of saliva flowing randomly, poor breathing, or even suffocation caused by oral secretions in the patient.

[0004] However, during the actual use process, when the oropharyngeal airway tube and the sputum suction tube are inserted into the patient's pharynx, since both the oropharyngeal airway tube and the sputum suction tube are directly facing the sputum in the pharynx, some sputum will directly enter the interior of the oropharyngeal airway tube during the insertion process. When oxygen is subsequently delivered to the patient's body through the ventilator and the oropharyngeal airway tube, the sputum that has entered the interior of the oropharyngeal airway tube will be sprayed deeper into the pharynx, causing discomfort to the patient or causing blockage deeper inside; Therefore, when the airway tube and the sputum suction tube in the prior art are inserted into the patient's pharynx, sputum is likely to directly enter the airway tube, and there is a problem that the sputum in the airway tube will be sprayed deeper into the patient's pharynx during subsequent oxygen delivery and ventilation, thereby causing discomfort to the patient or the sputum being sprayed deeper and causing blockage again. Utility Model Content

[0005] In view of the deficiencies of the prior art, the purpose of the present disclosure is to provide an intensive care ventilator, which solves the problem that when the tracheal tube and the sputum suction tube are inserted into the patient's pharynx in the prior art, sputum is likely to directly enter the tracheal tube, and there is a problem that when oxygen is supplied and ventilation is carried out subsequently, the sputum in the tracheal tube is sprayed into the deeper part of the patient's pharynx, thereby causing discomfort to the patient or the sputum is sprayed into the deeper part and blocked again.

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present disclosure with reference to the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present disclosure.

[0034] Herein, in combination with Figures 1 to 5Describe an embodiment of an intensive care ventilator. Specifically, the intensive care ventilator is configured as a split structure, which has components such as a first hose 100, a vacuum pump 200, an oxygen cylinder 300, a second hose 400, etc. The end of the first hose 100 away from the vacuum pump 200 is inserted into the patient's pharynx. By turning on the vacuum pump 200, a negative pressure environment is created inside the first hose 100, and the sputum accumulated in the patient's pharynx is sucked by the negative pressure, so that the sputum is inhaled into the first hose 100; when the sputum enters the first hose 100, the oxygen cylinder 300 can be turned on, and oxygen is introduced into the patient's pharynx through the second hose 400 to facilitate timely oxygen supply to the patient;

[0035] At the same time, the end of the second hose 400 away from the oxygen cylinder 300 is bent by 180°, which can prevent sputum from entering the second hose 400 when the second hose 400 is inserted into the patient's pharynx, and avoid spraying the sputum in the second hose 400 into the deeper part of the patient's pharynx when supplying oxygen to the patient through the oxygen cylinder 300 and the second hose 400.

[0036] Please refer to Figures 1 to 5 , an intensive care ventilator, including a first hose 100;

[0037] Both ends of the first hose 100 are open, and one end of the first hose 100 is connected to a vacuum pump 200;

[0038] A mounting block is fixed on the peripheral wall of the first hose 100 near the vacuum pump 200 end, and an oxygen cylinder 300 is fixed on the mounting block;

[0039] A second hose 400 is arranged inside the first hose 100. The second hose 400 is fixed on the inner wall of the first hose 100. One end of the second hose 400 passes through the peripheral wall of the first hose 100 and is connected to the output end of the oxygen cylinder 300. The other end of the second hose 400 extends out from the end of the first hose 100 away from the vacuum pump 200, and the end of the second hose 400 away from the oxygen cylinder 300 is bent 180° towards the central axis end of the first hose 100, and the nozzle of the end of the second hose 400 away from the oxygen cylinder 300 faces inside the first hose 100.

[0040] The first hose 100 is usually made of soft materials such as medical-grade silicone or polyvinyl chloride (PVC) to ensure safety and comfort; its diameter and length can be customized according to specific requirements to meet the usage requirements of different medical scenarios.

[0041] The vacuum pump 200 is one of the devices used to create a negative pressure environment. Such pumps can adopt various technologies, including rotary vane, scroll or screw designs, to provide different powers and suction speeds; they can also be selected as electric or manual types according to actual needs. The electric vacuum pump 200 provides convenient automatic operation functions, while the manual vacuum pump 200 allows more precise control.

[0042] The oxygen cylinder 300 is a compressed gas container used for supplying oxygen. It is usually made of steel or aluminum alloy, and its common specifications include 5 liters, 10 liters, etc., to meet the needs of different usage scenarios. In addition, the oxygen cylinder 300 is also equipped with devices such as a pressure gauge or a flow meter to monitor the oxygen storage situation and adjust the flow rate of the output oxygen to ensure that patients receive the accurate oxygen concentration and flow rate.

[0043] During use, the end of the first hose 100 far from the vacuum pump 200 is inserted into the patient's pharynx. By turning on the vacuum pump 200, a negative pressure environment is created inside the first hose 100, and the sputum accumulated in the patient's pharynx is aspirated through the negative pressure, causing the sputum to be inhaled into the first hose 100. When the sputum enters the first hose 100, the oxygen cylinder 300 can be turned on, and oxygen is introduced into the patient's pharynx through the second hose 400 to facilitate timely oxygen supply to the patient.

[0044] At the same time, the end of the second hose 400 far from the oxygen cylinder 300 is bent by 180°, which can prevent sputum from entering the second hose 400 when the second hose 400 is inserted into the patient's pharynx, and avoid spraying the sputum in the second hose 400 into the deeper part of the patient's pharynx when supplying oxygen to the patient through the oxygen cylinder 300 and the second hose 400.

[0045] To improve the sealing performance between the outer peripheral wall of the first hose 100 and the pharyngeal cavity, and avoid air leakage during the negative pressure sputum suction process, an annular airbag 500 is fixed on the outer peripheral wall of the end of the first hose 100 far from the vacuum pump 200. Through the elastic deformation of the annular airbag 500, the outer side wall of the annular airbag 500 is closely attached to the inner wall of the pharyngeal cavity.

[0046] To facilitate the insertion of the annular airbag 500 into the pharyngeal cavity and at the same time facilitate the use by a variety of patients with different pharyngeal cavities, an air inlet pipe is provided on the annular airbag 500. The air inlet pipe passes through the side wall of the first hose 100 and is connected to the inside of the second hose 400 in a through manner. A first electromagnetic valve is provided on the air inlet pipe, and a second electromagnetic valve 401 is provided on the second hose 400. The second electromagnetic valve 401 is located on the side of the air inlet pipe far from the oxygen cylinder 300. Initially, the second electromagnetic valve 401 is closed and the first electromagnetic valve is open. At the same time, the annular airbag 500 is in a deflated state. At this time, it is convenient to insert the annular airbag 500 and the first hose 100 into the patient's pharynx. When inserted to the required position, gas is supplied through the oxygen cylinder 300, causing the annular airbag 500 to expand and closely adhere to the inner wall of the pharyngeal cavity. At the same time, according to the different diameters of the patient's pharyngeal cavity, the amount of gas input into the annular airbag 500 can be controlled to make the annular airbag 500 expand to different degrees.

[0047] When the annular airbag 500 expands to the required size, close the first electromagnetic valve and open the second electromagnetic valve 401, and the oxygen can be delivered to the patient's body.

[0048] In order to facilitate the collection and treatment of the sputum aspirated into the first hose 100, a sputum discharge groove 101 is formed on the peripheral wall of the first hose 100 near the end close to the vacuum pump 200. A sputum collection box 600 is connected to the peripheral wall of the first hose 100. The end of the sputum collection box 600 close to the peripheral wall of the first hose 100 is open, and the open end of the sputum collection box 600 completely covers the sputum discharge groove 101. During use, the first hose 100 near the end close to the vacuum pump 200 is placed horizontally, and the sputum discharge groove 101 is placed downward. The aspirated sputum can flow into the first hose 100 and then to the sputum discharge groove 101, and finally fall into the sputum collection box 600.

[0049] In order to facilitate the timely replacement of the sputum collection box 600, the sputum collection box 600 and the first hose 100 are detachably connected, which is convenient for removing the sputum collection box 600 that is full or needs to be cleaned and replacing it with a new one.

[0050] In order to facilitate the disassembly between the sputum collection box 600 and the first hose 100, a pair of symmetrically placed first ear plates 700 are fixed on the outer side wall of the first hose 100. A pair of second ear plates 701 are fixedly connected to the sputum collection box 600. The first ear plates 700 and the second ear plates 701 correspond one by one. Screws 702 facing the second ear plates 701 are fixed on the first ear plates 700. Circular through holes coaxial with the screws 702 are formed on the second ear plates 701. The diameter of the circular through holes is larger than the maximum diameter of the screws 702. The screws 702 all pass through the circular through holes. Locking nuts 703 are sleeved on the screws 702 in a threaded connection. The locking nuts 703 are all located on the side of the second ear plates 701 away from the first ear plates 700. By rotating the locking nuts 703, the sputum collection box 600 can be stably installed on the outer side of the first hose 100. When the locking nuts 703 are removed from the screws 702, the sputum collection box 600 and the first hose 100 can be detachably separated.

[0051] In order to facilitate the subsequent cleaning of the first hose 100, a connector 102 is provided at the end of the first hose 100 close to the vacuum pump 200. Threaded teeth are provided on the outer peripheral wall of the connector 102. A threaded groove adapted thereto is provided at the output end of the vacuum pump 200, thereby realizing the detachable connection between the first hose 100 and the vacuum pump 200 and facilitating the subsequent disassembly and cleaning of the first hose 100.
