Compared with the prior art, the utility model discloses the beneficial effect who has as follows: the whole device is light and small, is convenient to carry and place, and does not occupy space; the sputum collection device has the advantages that the sputum to be collected can be guided out to the liquid storage bottle through the sputum suction pipe and the transition bin in the whole reciprocating process due to the fact that the sputum extrusion spring is driven to reciprocate by the sputum suction pipe, the sputum collection device is provided with the uneven bottom plate, sputum can conveniently and smoothly enter the transition bin, sputum samples can be collected by medical staff conveniently, and stability and sealing performance of the whole device in the using process are improved due to the fact that the silica gel layer is sleeved on the periphery of the piston; the closed circular ring is arranged at the handle, so that the comfort of hands is improved; because the bottom plate is slightly convex, when sputum is instantly sucked, the sputum can quickly flow from the bottom plate to the transition bin, so that backflow is prevented; the joint of the handle and the pull rod cylinder adopts a sealing device, so that the handle slides on the pull rod cylinder to form a closed structure; because the sliding plug is arranged at the lower end of the pull rod barrel, the tightness of the pull rod barrel can be guaranteed, and when the handle compresses the spring backwards, the sliding plug moves backwards as well, so that the whole space is closed.

Drawings

In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings required to be used in the technical description of the embodiments will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.

Fig. 1 is a schematic structural diagram of the present invention.

FIG. 2 is a schematic view of the handle and pull rod barrel connection.

Wherein, the device comprises 1-a pull rod cylinder, 2-a pull rod, 3-a piston, 4-a handle, 5-a spring, 6-a liquid storage bottle, 7-a transition bin, 8-a nozzle, 9-a bottom plate, 10-a sputum suction pipe and 11-a sliding plug.

Detailed Description

The technical solutions in the embodiments of the present invention are clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1-2, the sputum sample collection device comprises a pull rod barrel 1, a pull rod 2, a piston 3, a liquid storage bottle 6 and a handle 4, wherein the front end of the pull rod barrel 1 is sequentially connected with a transition bin 7 and a nozzle 8, the piston 3 is arranged in the pull rod barrel 1, the piston 3 is connected with the pull rod 2, the handle 4 for handheld pushing is arranged on the pull rod 2, and the rear end of the handle 4 is connected with a spring 5; the lower end of the transition bin 7 is communicated with a liquid storage bottle 6.

Preferably, the transition bin 7 is communicated with the storage bottle 6 through a threaded pipe, and the storage bottle 6 is screwed on the threaded pipe.

Preferably, an uneven bottom plate 9 is arranged in the nozzle 8.

Preferably, the inner wall of the connector 8 is threaded, so that the sputum suction tube 10 can be conveniently and fixedly connected.
