To maintain the following description of the embodiments of the present disclosure clear and concise, a detailed description of known functions and known components have been omitted from the present disclosure.

Referring to fig. 1-4, a stool sampling device for hospital clinical laboratory includes: a sampling component 1, an air bag block 2 and a tail tube 3. And the sampling component 1 is assembled and disassembled in a threaded connection mode with the tail pipe 3 through the base 11 so as to complete the transfer after the sample collection.

Further referring to fig. 2, the present invention further provides a technical solution, wherein the sampling assembly 1 comprises a guide rod 10, a base 11, four push-pull plates 12 and an outer hollow rod 13.

Specifically, a connecting block 14 is connected to a port in the bottom of the base 11 through a thread, the bottom of the connecting block 14 is connected to a top of the outer hollow rod 13 through a thread, the guide rod 10 penetrates through the base 11 and extends into the outer hollow rod 13, a spring 18 is movably sleeved at one end inside the outer hollow rod 13, one end of the spring 18 contacts with a spring seat 19 arranged on the guide rod 10, the other end of the spring contacts with a top wall inside the outer hollow rod 13, a guide rail groove 15 with an inner side movably inserted into the push-pull plate 12 is arranged on the outer hollow rod 13, a round rectangular groove 16 is arranged on an inner wall on one side of the guide rail groove 15, a round rod 17 located in the round rectangular groove 16 is arranged on an outer wall of an adjacent tail end of the guide rod 10, a hook ring is arranged at the top end of the push-pull plate 12 and is sleeved on the round rod 17, that is, when a button block 31 at, thereby drive four push-and-pull boards 12 through four round bar 17, upwards remove along the direction of guide rail groove 15 to open overcoat hollow rod 13 lower extreme, insert the overcoat hollow rod 13 in the excrement this moment, excrement and urine can get into the inside of overcoat hollow rod 13, pull out overcoat hollow rod 13, then unclamp the button piece 31, make guide bar 10 automatic re-setting under the effect of spring 18, and push-and-pull board 12 is sealed along with reseing, stays the excrement and urine sample in overcoat hollow rod 13.

Furthermore, when the stool is liquid-like, after the outer hollow rod 13 is inserted into the stool, the knob block 31 is released, so that the guide rod 10 automatically returns under the action of the spring 18, and the push-pull plate 12 is sealed along with the return, so that the stool sample is left in the outer hollow rod 13.

How the push-pull plate 12 seals the outer sleeve hollow rod 13 is because the bottom end of the push-pull plate 12 is provided with the rubber convex edge and is inserted into the clamping groove at the bottom end of the through groove of the outer sleeve hollow rod 13 to realize sealing.

Furthermore, referring to fig. 3, in order to reduce the stool adhered to the surface of the hollow rod 13, the solution is specifically that the top of the air bag block 2 is adhered to the bottom of the hollow rod 13, the adhesion is reduced by glue, and the outer wall is provided with a film coat 30 and wrapped on the outer wall of the hollow rod 13, when the hollow rod 13 is coated, the air bag block 2 is adhered to the stool and the film coat 30 is taken away from the hollow rod 13, but if the stool is similar to liquid, medical tweezers are needed to assist in the process.

It should be noted that, when the sampling assembly 1 is used, the depth of the outer hollow rod 13 inserted into the feces is not more than the guard ring 34 sleeved on the central axis of the outer wall

As shown in fig. 2, the button block 31 is engaged with a rubber seat 32 fixedly installed in the top port of the base 11.

As shown in fig. 2, a sealing block 33 is fixedly mounted on the inner wall of the outer hollow rod 13 and is located in the middle of the outer hollow rod 13, so that one part of the outer hollow rod 13 is separated into two parts to form a sample chamber.

As shown in fig. 2, the length of the four push-pull plates 12 is half of the length of the outer hollow rod 13.

It will be appreciated by those skilled in the art that other similar connecting means, such as welding, bonding or screwing, may also be used to implement the present invention.

The above embodiments are merely exemplary embodiments of the present invention, which is not intended to limit the present invention, and the scope of the present invention is defined by the appended claims. Various modifications and equivalents may be made by those skilled in the art to the present invention without departing from the spirit and scope of the invention, and such modifications and equivalents should be considered to be within the scope of the invention.
