Description

A disposable sputum suction device

technical field

The utility model relates to the field of medical equipment, in particular to a disposable phlegm suction device.

Background technique

The function of the sputum suction device is to effectively clean the airway and more sputum secretions, or to inhale the vomit in the airway by mistake. The main principle is to smoothly suck out the secretions in the airway through negative pressure, relieve airway obstruction and restore breathing. patency.

Existing medical sputum suction devices usually include a reusable sputum suction tank and a disposable sputum suction liner. Before patients use the sputum aspirator, the medical staff need to install the disposable sputum aspirator liner, connect the sputum suction tube and the negative pressure tube, and then use the sputum aspirator to the patient. When the respiratory secretions in the sputum suction liner reach a certain storage capacity, the medical staff not only need to replace the sputum suction liner, but also need to clean and disinfect the sputum suction tank. The entire replacement and cleaning process is time-consuming and laborious, which not only reduces the work efficiency of medical staff, but also during the entire process of cleaning and disinfecting the inner liner of the sputum suction tank, although medical staff wear protective equipment, they may still come into contact with respiratory secretions. Suffering from infectious diseases at the same time will greatly increase the risk of infection. Later, for the convenience of nursing, a disposable sputum suction device was invented, which combined the sputum suction tank and inner tank into one, which greatly simplified the work of nursing staff.

However, it is found in actual work that there are still some criminals who illegally recycle used disposable sputum suction devices, sterilize them and repack them for use, especially in some remote areas with underdeveloped medical and health conditions. phenomenon is more common.

Because the sputum suction device often contains a large amount of respiratory secretions discharged by the human body, which is mixed with a large number of bacteria, it is difficult to completely remove it even after high-temperature disinfection, and the respiratory tract of patients who need to use such medical equipment is usually more fragile than ordinary people, so If such illegally recovered disposable sputum aspirators are put into use again, it will cause unpredictable risks and harm to the health of patients, so a disposable sputum aspirator with self-destruct function is manufactured to avoid illegal It is imperative that the molecules are reused.

Utility model content

In order to solve the above problems, the purpose of this utility model is to provide a disposable sputum aspirator, which solves the technical problem that the disposable sputum aspirator is illegally reused.

In order to achieve the above object, the utility model adopts the following technical scheme: the scheme includes a cylindrical sputum suction tank, the upper end surface of the sputum suction tank is respectively provided with a sputum suction tube and a negative pressure tube connected with the sputum suction tank in parallel, The fixing hoop on the outer peripheral wall of the middle part of the sputum suction tank body is provided with a fixed collar for fixing the sputum suction tank, and a three-claw limit buckle is embedded in the mouth of the sputum suction tube and the negative pressure tube; the sputum suction tube and The top of the negative pressure tube wall is fixedly connected with a connecting belt, and the movable end of the connecting belt is fixedly connected with a sealing plug for closing the sputum suction tube and the negative pressure tube. Sealing rings that match the nozzles of the pressure tubes.

Further, the left side wall and the right side wall of the fixing collar are respectively hinged with adhesive suction cups and hooks for fixing the use position of the sputum suction tank, and the hinges of the fixing collar and the adhesive suction cups and hooks All are provided with a locking device for locking the use direction of the sticky suction cup and the hook.

Further, the locking device includes a locking nut and a locking bolt.

The utility model has the following beneficial effects:

The utility model is designed to use a sealing plug, and the sealing plug cannot be pulled out after the sputum suction tube and the negative pressure tube are blocked, so that the sputum suction tank cannot be used again, and the medical hidden danger of the second use of the sputum suction device is reduced.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail:

Referring to Figures 1-4, this embodiment includes a white transparent sputum suction tank 1 with a cylindrical main body, and the middle part of the upper end surface of the sputum suction tank 1 is connected in parallel and fixedly provided with a sputum suction tube 2 and a negative pressure tube 3; The volume range of tank 1 is 2500-3000M.

The side wall of the tank body 11 of the sputum suction tank 1 is fixed with a fixed collar 4 for fixing the use position of the sputum suction tank 1; The adhesive suction cup 42 and the hook 41 in the use position, the hinge of the fixed collar 4 and the adhesive suction cup 42 and the hook 41 is provided with a locking device for locking the use direction of the adhesive suction cup 42 and the hook 41 43. The locking device 43 includes a locking bolt 432 and a locking nut 431 . When using the sputum suction tank 1, you can use the hook 41 to hang the sputum suction tank 1 on the bed rail, table top, etc. or use the adhesive suction cup 42 to attach the sputum suction tank 1 to the plane, and choose a suitable position to place the sputum suction The tank 1 is convenient for nurses to carry out treatment; when the sputum suction tank 1 is not in use, the adhesive suction cup 42 and the hook 41 can be rotated left and right to facilitate the storage of the sputum suction tank 1 .

The mouth of the sputum suction tube 2 and the negative pressure tube 3 is embedded with a three-claw limit buckle 6; the top of the tube wall of the sputum suction tube 2 and the negative pressure tube 3 is fixedly connected with a connecting belt 51, and the movement of the connecting belt 51 The end is fixedly connected with a sealing plug 5 for sealing the sputum suction tube 2 and the negative pressure tube 3 pipelines _. The connecting belt 51 is fixedly provided with a sealing ring 52 for sealing the mouth of the mouth of the sputum suction pipe 2 and the negative pressure pipe 3, so that the human respiratory secretions stored in the sputum suction tank 1 will not leakage. Both the sealing plug 5 and the three-claw limit buckle 51 are made of plastic material.

The working principle is roughly as follows: see Figure 3, in the initial state, the sealing plug 5 is not inserted into the tube of the suction tube 2 and the negative pressure tube 3, and the corresponding tubes are respectively connected to the suction tube 2 and the negative pressure tube 3 Start treatment. As shown in Figure 4, when the treatment ends or the storage capacity of the sputum suction tank 1 reaches the upper limit, insert the arc-shaped sealing plug 5 into the tube of the sputum suction tube 2 and the negative pressure tube 3, and pass the three-claw limit buckle 6 The setting of the inserted sputum suction tube 2 and the sealing plug 5 in the tube of the negative pressure tube 3 are clamped. At this time, people cannot operate from the tube, push out the sealing plug 5 and the external force cannot pull the sealing plug 5 out of the tube. The sealing plug 5 cannot be disengaged. Therefore, the sputum suction tube 2 and the negative pressure tube 3 are blocked to prevent secondary use of the sputum suction tank 1 and reduce potential safety hazards.

The above is only the specific implementation of the utility model, and does not limit the patent scope of the utility model. Any equivalent structural transformation made by using the utility model specification and accompanying drawings, or directly or indirectly used in other related technologies Fields are all included in the scope of patent protection of the utility model in the same way.
