Description

A retractable cylindrical sputum suction device

technical field

The invention relates to a medical device, in particular to a retractable cylindrical sputum suction device.

Background technique

Sputum suction devices can be divided into manual and electric ones. The existing manual sputum suction devices are usually designed to be larger due to the need to generate sufficient suction, which can increase the stroke of the piston, but it is very difficult to carry and place. It is inconvenient; and the usual manual sputum suction device needs to install a sputum storage bottle at the front end. Since the position of the sputum storage bottle is not fixed, it needs to be placed in a fixed position or held by hand, which is very inconvenient to use.

Preferably, an air suction hole is also provided at the center of the isolation plate.

Preferably, the side wall of the outer cylinder and the right side wall of the inner cylinder are provided with sockets, and detachable pins are installed in the sockets.

Preferably, a spring is further arranged on the piston rod.

Beneficial effect: the present invention has the following advantages compared with the existing technical solutions:

(1) When the present invention is in use, after the outer cylinder is pulled apart, a plug is inserted into the jack to fix the position of the outer cylinder, the handle is held by hand, and the suction force is generated by hooking the fingers on the pull rod and pulling the piston, thereby enabling Inhale the sputum, and when not in use, the outer cylinder can insert the inner cylinder into the body, and then fix the position through the bolt, so that the overall structure becomes smaller, the volume becomes smaller, and it is easier to carry and place;

(2) The present invention replaces the traditional sputum storage bottle by installing a sputum storage cylinder, which is installed at the left end of the inner cylinder body. When sucking sputum, the suction generated by the piston is transmitted to the sputum storage cylinder through the suction hole, and the sputum storage cylinder The sputum canister sucks sputum into the sputum storage box through the suction tube, and the sucked sputum can be placed in the sputum storage box, and the sputum storage box can be disassembled for easy cleaning and pouring out the sputum inside, and the outer diameter of the sputum storage box is larger , can store more sputum, very convenient to use.

detailed description

The present invention will be further illustrated below in conjunction with the accompanying drawings and specific embodiments. This embodiment is implemented on the premise of the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

As shown in Figure 1, a telescopic cylindrical sputum suction device includes an inner cylinder 1, an outer cylinder 2, a piston 3, a piston rod 4, a pull rod 5, a handle 6, a separation plate 7 and a sputum storage cylinder 8; The outer diameter of the sputum storage tube 8 is larger than the outer diameter of the inner cylinder 1 and is detachably installed on the left end outer wall of the inner cylinder 1, the outer cylinder 2 is set on the right end outer wall of the inner cylinder 1, and the outer cylinder The body 2 can move on the inner cylinder 1, and the handle 6 is installed on the right end of the outer cylinder 1; the piston 3 is arranged in the inner cylinder 1, and one end of the piston rod 4 is connected to the piston 2, and the other end is connected with the inner cylinder. The right end of the body 1 protrudes and is connected with the pull rod 5, the pull rod 5 is installed vertically and protrudes to the outside of the outer cylinder 2 to cooperate with the handle 6, and the isolation plate 7 is installed at the left end of the inner cylinder 1 .

Wherein, the outer diameter of the sputum storage tube 8 is twice the outer diameter of the inner cylinder body 1, and an internal thread connector 9 is arranged on the position matching the outer diameter of the inner cylinder body 1 on the sputum storage tube 8, and the inner The outer wall of the left end of the cylinder body 1 is provided with an external thread 10 used in conjunction with the internal thread connector 9 , and the sputum storage tube 8 is also provided with an air suction pipe 11 .
