Problems solved by technology

But it has the following disadvantages: when the piston rod is moved backwards, if you want to continue to suck sputum, you need to push the piston rod forward to the initial position. During the forward pushing process, the previously sucked gas will be pushed back to the sputum collection container , which in turn may push the sputum sucked in the suction tube and hose back into the patient's body, which will affect the suction efficiency and cause discomfort to the patient
But it has the following disadvantages: the adoption cost of the one-way valve is relatively high, and a direct connection relationship between the sputum suction tube and the negative pressure generating device is established, and the one-way valve is arranged at the outlet end of the sputum suction tube and the above-mentioned sputum suction tube and negative pressure generating device. The connection of the pressure generating device, the one-way valve has been contaminated, and the internal structure of the one-way valve is relatively complicated, which makes the cleaning work of the one-way valve very heavy, which in turn affects the secondary application of the sputum suction device

Embodiment 1

[0029] An emergency sputum suction device for respiratory medicine, comprising a sputum collection container 1 and a sputum suction tube 2 and an air suction tube 3 located above the sputum collection container 1 and respectively connected to the inner cavity of the sputum collection container 1, the sputum suction tube 2 is The port is connected with a sputum suction hose 4, the other end of the sputum suction hose 4 is provided with a sputum suction head 5, and the upper port of the suction pipe 3 is connected with a piston type suction device 6;

[0030] Between the air extraction pipe 3 and the piston type air extraction device 6, a sealed chamber 7 communicating with the air extraction pipe 3 and the piston type air extraction device 6 is provided, and the air extraction pipe 3 and the piston type air extraction device 6 are arranged in the sealed chamber 7 On the opposite sides, the side of the sealed chamber 7 connected to the piston-type air extraction device 6 is provi...

Embodiment 2

[0037] The difference between this embodiment and embodiment 1 is:

[0038] In this example, if figure 1 As shown, the air release port 8 and the upper port of the exhaust pipe 3 are respectively located at the upper and lower ends of the sealed cavity 7, the connecting rod 11 is "Z" shaped, and the push rod 12 is connected to the "Z" shaped connecting rod 11 middle part. Because the "Z" shaped connecting rod 11 is symmetrical about its center, the stability when the connecting rod 11 is pushed by the push rod 12 is better, but the matching installation of the connecting rod 11 with the upper port of the exhaust pipe 3 and the air discharge port 8 is relatively inconvenient.

[0039] Others are the same as embodiment 1.

[0040] The specific application process of the above-mentioned emergency sputum suction device in respiratory medicine is as follows:

[0041] (1) After inserting the sputum suction head 5 into the patient's sputum site, first pull the push handle 13 along...

Abstract

The invention discloses an emergency sputum suction device for respiratory internal medicine, which belongs to the field of medical equipment, and comprises a sputum suction head, a sputum suction hose, a sputum suction tube, a sputum collection container and a piston-type suction device connected in sequence, the suction tube and the piston There is a sealing cavity between the type air extraction devices, the side of the sealing cavity connected to the piston type air extraction device is provided with an air release port, and a moving switch component is arranged in the sealing cavity, and the moving switch component includes respectively used to block the upper port of the suction pipe and the The first plugging sleeve and the second plugging sleeve of the air release port are connected with a connecting rod between the first plugging sleeve and the second sealing sleeve, and the connecting rod is fixedly connected to the push rod, and the free end of the push rod is provided with a push handle; the central axis of the piston body There is a moving groove for the push rod to pass through, and the piston rod surface of the piston body is also provided with a perforation for the push handle to move, and the perforation is parallel to the moving groove and communicates with the moving groove. The invention can realize the function of continuously performing sputum suction operation, and has the advantages of low cost and convenient cleaning.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to an emergency sputum suction device for respiratory medicine. Background technique [0002] Aspirator is an indispensable and important tool to prevent and treat airway obstruction of patients and rescue suffocation. As a device for treating patients' pharynx, it is widely used. Therefore, aspirator in respiratory medicine is an important medical device. A general sputum suction device includes a sputum suction head, a sputum suction hose, a sputum suction tube, a sputum collection container, and a negative pressure generating device connected in sequence. , so that the inner cavity forms a negative pressure to generate suction on the suction tube, so that the sputum is sucked from the suction head, and then enters the sputum collection container along the suction hose and suction tube to realize the sputum suction function. [0003] At present, the negative pressure generating d...
