Abstract

A disposable adjustable negative pressure aspirator tube is characterized by comprising a suction tube, a small connector, a large connector and a pressure regulating valve. One end of the suction tube is connected with the small connector, and the other end of the suction tube is connected with the large connector, and meanwhile the small connector can be connected with a common aspirator head or an electrotome aspirator head, and the large connector is connected with an aspirator bottle. Meanwhile, the pressure regulating valve is arranged on the suction tube, the regulating valve is a sliding pressure valve, and the distance of the pressure regulating valve and the small connector is 2 cm. The disposable adjustable negative pressure aspirator tube has the advantages that the structure of the disposable adjustable negative pressure aspirator tube can well enable working of instruments to be smooth, suction pressure can be adjusted accurately at any time in using process, the working amount of a user is reduced, and meanwhile disposable using can better guarantee the sanitation and the health of a patient.

Description

Disposable adjustable negative pressure suction tube

technical field

The utility model relates to a disposable adjustable negative pressure suction tube, which belongs to the field of medical equipment.

Background technique

The suction device is used to suck the contents of bleeding, exudate, pus, and chest viscera during the operation, so as to make the operation clear and reduce the chance of contamination. The principle of the aspirator is very simple. It is to create the negative pressure state of the suction head through a certain method, so that the atmospheric pressure will squeeze the material outside the suction head to the suction head, thereby completing the "suction" effect, but the negative pressure at this stage The suction device is just a round tube with the same diameter, which is easy to be blocked by suction, and the pressure cannot be adjusted. As a medical product, its repeated use cannot better protect the health of patients.

Utility model content

The purpose of the utility model is to provide a one-time adjustable negative pressure suction tube to overcome the defects that the current suction tube cannot regulate the pressure well and can be used repeatedly.

In order to solve the problems of the technologies described above, the utility model adopts the following technical solutions:

The disposable adjustable negative pressure suction tube is characterized in that it includes a suction tube, a small connector, a large connector and a pressure regulating valve. One end of the suction tube is connected to the small connector, and the other end is connected to the large connector. The suction head or the electric knife suction head is connected, and the Dalian street is connected to the suction bottle. The structure of the small front end and the large rear end can prevent the suction tube from stopping due to the blockage of the suctioned material during the working process.

At the same time, a pressure regulating valve is set on the suction pipe, and the pressure regulating valve is a sliding regulating valve, with a distance of 2cm from the small connector. The sliding regulating valve allows the user to more conveniently and accurately regulate the pressure as needed.

The beneficial effects of the utility model are: the structure of the one-time adjustable negative pressure suction tube provided by the utility model can ensure the smooth operation of the device, and the suction pressure can be adjusted accurately at any time according to the needs during use. The size reduces the workload of the user, and at the same time, the one-time use can better protect the health of the patient.

Detailed ways

The utility model is described below in conjunction with specific embodiment:

As shown in Figure 1, the utility model provides a disposable adjustable negative pressure suction tube, which includes a suction tube 1, a small connector 2, Dalian Street 3 and a pressure regulating valve 4, and the small connector is connected to one end of the suction tube 1 The other end is connected to the large connector 3, and at the same time, a pressure regulating valve 4 is set at a distance of 2 cm from the small connector 2 on the suction tube 1. The small connector 2 can be connected to the head of an ordinary suction device or an electric knife suction device. Dalian Street 4 is connected to the suction bottle. During use, the suction pressure can be weakened with the opening of the pressure regulating valve 4, and the suction pressure can be increased by closing the pressure regulating valve 4. The pressure regulating valve 4 can control the suction pressure by sliding , to meet the needs of users.
