Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a portable suction device for critical care. Background Technology

[0002] Currently, many critically ill patients experience difficulty in suctioning sputum, requiring assistance from medical staff to remove the sputum and maintain smooth breathing. Excessive accumulation of thick sputum and viscous fluid not only affects the patient's breathing but also hinders the patient's ability to take oral medications, increasing the burden on medical staff in treating patients and, in severe cases, even leading to death.

[0003] Furthermore, many respiratory diseases are infectious. When using existing suction devices, the sputum is stored in a storage container, and once it is full, it is directly discharged. This process carries the risk of further leakage of pathogens from the sputum, leading to infection. Therefore, there is an urgent need for a new type of suction device, especially for critically ill patients with infectious diseases, that can provide convenient suction while also avoiding unnecessary infection through storage. Utility Model Content

[0004] The purpose of this invention is to provide a novel portable suction device for critically ill patients, so as to achieve suctioning of sputum for critically ill patients and to minimize the risk of infection caused by leakage to a certain extent.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A portable suction device for severe cases includes:

[0007] A sputum storage structure includes a ventilator, an interface mounting seat is fixedly installed on the upper side of the ventilator, an internal pipe is snapped into the top of the interface mounting seat, a tank cover is fixedly installed at the bottom of the ventilator, and a sputum storage tank is screwed onto the bottom side of the tank cover.

[0008] An extraction structure, one end of which is connected to one side of the gas-releasing chamber;

[0009] The insertion tube structure has one end connected to the upper side of the interface mounting base.

[0010] Furthermore, the sputum storage structure also includes:

[0011] An air extraction port is fixedly installed on one side of the air venting chamber;

[0012] An inner tube mounting groove is interposed at the top of the interface mounting base;

[0013] A rotary connector is snapped into the opening on the inner tube mounting groove.

[0014] A suction port, which is fixedly installed on the upper side of the rotary port;

[0015] A swivel joint is engaged with the lower opening of the inner tube mounting groove.

[0016] Furthermore, the screw-on base and the screw-on interface are screwed together, and an internal pipe is fixedly installed at the bottom of the screw-on base. The lower end of the internal pipe extends into the sputum storage container. The sputum storage container is used to store sputum and add disinfectant. Before each use after cleaning, the container can be unscrewed and an appropriate amount of disinfectant can be added.

[0017] Furthermore, the extraction structure includes:

[0018] An air extraction connector is inserted into an air extraction port.

[0019] An air extraction pipe, one end of which is fixedly connected to an air extraction connector;

[0020] An air extraction port is fixedly connected to the other end of an air extraction pipe.

[0021] The base has an air extraction port on one side;

[0022] An air pump, which is fixedly installed on the other side of the base;

[0023] The exhaust port is located on the upper side of the air pump head.

[0024] Furthermore, the extraction structure also includes:

[0025] A handle is fixedly installed on the bottom side of the base, and a rechargeable battery is embedded inside the handle;

[0026] A charging interface is embedded in the lower end of the handle.

[0027] Furthermore, the cannulation structure also includes:

[0028] A catheter connector, which is sleeved with a suction port;

[0029] The cannula body, one end of which is fixedly connected to the cannula connector;

[0030] A sputum suction head is fixedly installed at the other end of the intubation tube body.

[0031] Compared with the prior art, the beneficial effects of this utility model are:

[0032] 1. Select a suitable disinfectant solvent and fill it into the sputum collection container. Insert the intubation device into the patient's respiratory system and activate the suction device to begin suctioning. This creates a negative pressure space in the sputum collection container, allowing air from the internal tubing and intubation device to enter the container and rise as bubbles to balance the air pressure in the relaxation chamber. This creates a negative pressure environment within the intubation device to suction sputum from the patient's respiratory system. Disinfectant solvent can be added to the sputum collection container, and the sputum will directly enter the solvent, achieving direct disinfection of pathogens. After suctioning, the sputum collection container and intubation device can be removed and discarded. Other components can be disinfected and reused, effectively reducing the probability of infectious patients' sputum becoming a source of infection.

[0033] 2. The suction port and internal tube, which come into direct contact with sputum, are designed to be detachable for easy and thorough disinfection. They can also be used as disposable items and discarded after use, further increasing ease of use. Attached Figure Description

Detailed Implementation

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] Please see Figures 1-5 In this embodiment of the present invention, a portable sputum suction device for severe cases includes a sputum storage structure 1, an extraction structure 2, and an insertion structure 3. It includes a relief chamber 101, an interface mounting base 102 fixedly installed on the upper side of the relief chamber 101, an internal pipe 108 snapped into the top of the interface mounting base 102, a canister cap 109 fixedly installed at the bottom of the relief chamber 101, and a sputum storage canister 110 screwed onto the bottom side of the canister cap 109. One end of the extraction structure 2 is connected to one side of the relief chamber 101; one end of the insertion structure 3 is connected to the upper side of the interface mounting base 102.

[0042] Specifically, the extraction structure 2, the intubation structure 3, and the sputum storage structure 1 are interconnected. The intubation structure 3 and the sputum storage container 110 are disposable. A suitable disinfectant is selected according to the patient's condition and placed into the sputum storage container 110. The intubation structure 3 is inserted into the patient's respiratory system, and the extraction structure 2 is activated to perform suction, creating a negative pressure space in the sputum storage container 110. Air from the internal tube 108 and the intubation structure 3 enters the sputum storage container 110 and enters the top of the sputum storage container 110 in the form of bubbles to balance the air pressure in the relief chamber 101. This creates a negative pressure environment in the intubation structure 3 to extract sputum from the patient's respiratory system. The sputum directly enters the sputum storage container 110 and comes into contact with the disinfectant that has been added, directly achieving sterilization. After suctioning, the sputum storage container 110 and the intubation structure 3 are removed and discarded. Other components are disinfected and reused, effectively reducing the probability that infectious patient sputum may become a source of infection. Example 1

[0043] like Figure 1 As shown, in this embodiment, the extraction structure 2 includes a base 201, an air pump 202, an exhaust port 203, an extraction port 204, an extraction pipe 205, an extraction connector 206, a handle 207, and a charging interface 208. The extraction connector 206 and the extraction interface 103 are plugged into each other. One end of the extraction pipe 205 is fixedly connected to the extraction connector 206. The extraction port 204 is fixedly connected to the other end of the extraction pipe 205. An extraction port 204 is provided on one side of the base 201. The air pump 202 is fixedly installed on the other side of the base 201. The exhaust port 203 is provided on the upper side of the pump head of the air pump 202. The handle 207 is fixedly installed on the bottom side of the base 201, and a rechargeable battery is embedded inside the handle 207. The charging interface 208 is embedded in the lower end of the handle 207.

[0044] In this embodiment, by holding the handle 207 and using battery power, the air pump 202 is started, drawing air into the pump head of the air pump 202 from the air extraction pipe 205 and expelling it from the exhaust port 203, thus achieving the air extraction effect.

[0045] like Figures 4-5 As shown, in this embodiment, the intubation structure 3 also includes an intubation body 301, a sputum suction head 302, and an intubation connector 303. The intubation connector 303 is sleeved with the sputum suction interface 105. One end of the intubation body 301 is fixedly connected to the intubation connector 303. The sputum suction head 302 is fixedly installed on the other end of the intubation body 301.

[0046] In practice, the intubation body 301 is designed to be detachable. It is installed by interlocking the intubation connector 303 with the suction port 105. The appropriate type of intubation body 301 and sputum suction head 302 structure can be selected according to the condition of the critically ill patient. Ordinary patients use ordinary intubation body 301, while patients who need open laryngoscopy can choose a thinner intubation body 301 and sputum suction head 302 to avoid secondary damage to the larynx opening. Example 2

[0047] Based on Example 1, in order to compensate for the fact that when sputum is drawn into the sputum storage container 110 in Example 1, the sputum will come into direct contact with the suction port 105 and the internal pipe 108, and the internal pipe 108 is installed inside the air venting chamber 101 and the port mounting base 102, the disinfection of the suction port 105 and the internal pipe 108 is inconvenient.

[0048] like Figure 5 As shown, in this embodiment, the sputum storage structure 1 further includes an air suction port 103, an inner tube mounting groove 104, a suction port 105, a swivel port 106, and a swivel seat 107. The air suction port 103 is fixedly installed on one side of the air venting chamber 101; the inner tube mounting groove 104 is inserted into the top of the port mounting seat 102; the swivel port 106 is snapped into the upper opening of the inner tube mounting groove 104; the suction port 105 is fixedly installed on the upper side of the swivel port 106; the swivel seat 107 is snapped into the lower opening of the inner tube mounting groove 104; the swivel seat 107 and the swivel port 106 are screwed together; an internal pipe 108 is fixedly installed at the bottom of the swivel seat 107, and the lower end of the internal pipe 108 extends into the sputum storage container 110.

[0049] In practice, the suction port 105 and the internal tube 108, which come into direct contact with sputum, are designed to be detachable for easy and thorough disinfection. They can also be used as disposable items and discarded after use, further increasing ease of use.
