Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a portable disposable negative pressure sputum aspirator for respiratory internal medicine nursing. Background Art

[0002] Many critically ill, elderly, and comatose patients have problems with weak coughs, slow cough reflexes, or incomplete swallowing function. They often cannot clear respiratory secretions by themselves, and will experience symptoms such as breath holding, chest tightness, and dyspnea. If sputum cannot be cleared in the respiratory tract for a long time, it will also lead to lung infection. A sputum aspirator is a device that uses negative pressure suction to suck out sputum in the human body. Currently, sputum aspirators are mainly electric multifunctional negative pressure sputum aspirators and simple manual sputum aspirators. The electric type uses the negative pressure principle to suction sputum and oral care, and is used for routine sputum suction, tracheotomy, and other treatments for patients. The existing sputum aspirator connects two liquid collection bottles through a catheter to form a negative pressure sputum suction device, and places the liquid collection bottle on a special fixed base to achieve the sputum suction function. However, in clinical use, the assembly of the suction device takes a certain amount of time, delaying the time for rescuing patients; secondly, the fixed base, catheter and liquid collection bottle need to be cleaned after use, which not only increases the risk of medical staff coming into contact with the patient's body fluids and getting infected, but also increases the workload of medical staff; in addition, the connection between the catheter and the liquid collection bottle is not airtight enough and is easy to loosen, thus affecting treatment. Therefore, a portable disposable negative pressure suction device for respiratory medicine nursing is needed.

[0025] like Figure 1-5 As shown, a portable disposable negative pressure sputum suction device for respiratory medicine nursing includes an adhesive sheet 1, which plays a role of fixing a liquid storage mechanism 2. The upper end of the adhesive sheet 1 is fixedly connected to the liquid storage mechanism 2, and a sleeve 6 is slidably connected to the upper right side of the liquid storage mechanism 2. A hose 5 is fixedly connected to the upper end of the sleeve 6, which plays a role of connecting the sputum suction mechanism 3 and the liquid storage mechanism 2, so that the sputum sucked out by the sputum suction mechanism 3 enters the liquid storage mechanism 2, and the end of the hose 5 away from the sleeve 6 is fixedly connected to the sputum suction mechanism 3, and the outer surface of the hose 5 close to the sputum suction mechanism 3 is slidably connected to an adhesive sliding sleeve 4, which plays a role of fixing the hose 5.

[0026] It should be noted that the utility model also needs to be used in conjunction with an external vacuum device (not shown in the utility model), wherein the external vacuum device includes a negative pressure pump, which is a pump that works on the principle of negative pressure and is usually used to transport gas or liquid. In the negative pressure pump, there is a suction chamber and a compression chamber, and the pressure in the suction chamber is lower than the atmospheric pressure, so that the gas or liquid is sucked in and compressed, and then discharged through the discharge pipe. In the portable disposable negative pressure suction device for respiratory medicine nursing, the function of the negative pressure pump is to generate negative pressure suction to suck secretions such as sputum out of the respiratory tract. Negative pressure suction can effectively absorb secretions such as sputum, keep the respiratory tract unobstructed, and relieve symptoms such as dyspnea.

[0027] In order to achieve the purpose of storing sputum, Figure 4 As shown, the liquid storage mechanism 2 includes a liquid storage tank 21, a partition plate 22 is fixedly connected to the middle of the inner cavity of the liquid storage tank 21, an upper cover assembly 23 is fixedly connected to the upper end of the liquid storage tank 21 and the upper end of the partition plate 22, and the lower end of the liquid storage tank 21 is fixedly connected to the upper end of the adhesive sheet 1.

[0028] In detail, first, the liquid storage tank 21 is pasted at a suitable position through the adhesive sheet 1, and then connected to the external vacuum device through the upper cover group 23 (not shown in the present utility model), the sucked sputum is collected by the liquid storage tank 21, and the inner cavity of the liquid storage tank 21 is separated by the partition plate 22, and the upper cover group 23 is used to prevent harmful substances in the sputum from contaminating the external vacuum device, thereby achieving the purpose of storing the sputum.

[0029] Further explanation, such as Figure 5 As shown, the upper cover group 23 includes an upper cover plate 231, and a connecting pipe 234 is symmetrically fixedly connected to the middle of the upper end of the upper cover plate 231, and a circular sleeve 232 is fixedly connected to the left middle part of the lower end of the upper cover plate 231, and the circular sleeve 232 is located directly below the connecting pipe 234 on the left, and a filter plate 233 is fixedly connected to the inner cavity of the circular sleeve 232, and the upper end of the liquid storage tank 21 and the upper end of the partition plate 22 are fixedly connected to the lower end of the upper cover plate 231.

[0030] First, the upper cover 231 is fixedly connected to the liquid storage tank 21 and the partition plate 22, and the two connecting pipes 234 on the upper part of the upper cover 231 are respectively connected to the sleeve 6 and the external air extraction device to form a closed space to achieve good sealing and connectivity. The filter sheet 233 installed in the inner cavity of the circular sleeve 232 is used to filter the gas containing harmful substances in sputum in the liquid storage tank 21 to prevent the harmful substances in the sputum from contaminating the external air extraction device.

[0031] In order to achieve the purpose of suctioning the patient's sputum, Figure 2 and Figure 3As shown, the sputum suction mechanism 3 includes a sputum suction tube 31, a bite prevention group 32 is slidably connected to the middle of the outer surface of the sputum suction tube 31, a gas blocking valve 33 is fixedly connected to the left end of the sputum suction tube 31, and the left end of the gas blocking valve 33 is fixedly connected to the end of the hose 5 away from the sleeve 6;

[0032] The anti-bite group 32 includes a bite block 322, a through hole 321 is opened in the middle of the right arc surface of the bite block 322, a push tube 323 is fixedly connected to the middle of the left arc surface of the bite block 322, and the inner cavity of the through hole 321 is communicated with the inner cavity of the push tube 323, and the inner cavity of the through hole 321 and the inner cavity of the push tube 323 are jointly slidably connected to the middle of the outer surface of the suction tube 31.

[0033] By pushing the push tube 323, the patient's teeth bite on the bite block 322, which protects the suction tube 31 and prevents the teeth from biting the suction tube 31, causing the suction tube 31 to be blocked and affecting the suction effect. The liquid storage tank 21 is made to slide in the through hole 321 and the inner cavity of the push tube 323 into the phlegm congestion in the patient's throat. The external vacuum device cooperates with the liquid storage mechanism 2, the sleeve 6 and the hose 5 to close the air blocking valve 33, so that the suction tube can absorb the phlegm, thereby achieving the purpose of absorbing the patient's sputum.
