Description

Technical Field

[0001] The utility model relates to the technical field of medical appliances, in particular to a fecal sampler which is leak-proof after puncture. Background Art

[0002] Clinical stool examination is one of the three major routine tests for clinical laboratory examinations in medical institutions, namely, blood test, stool test, and urine test. Throughout history, there has been no strict requirement for the sampler for stool. Early containers included matchboxes and paper boxes, and now mostly plastic boxes or cups of various shapes and sizes. When taking samples, the sampler uses bamboo or wooden sticks to pick out samples with a plastic spoon. Then, the medical inspection staff uses the same method to pick a small amount of sample from the container of the suspected part, and add a drop of physiological saline or buffer solution to prepare a microscopic examination or other verification. Adopting the above-mentioned sampling and detection method has the following disadvantages: large pollution, difficult to control the sampling amount, disputes and disputes arise about the size of the sampling amount, and medical staff are exposed to the air most of the time during the stool sampling process, which not only makes the indoor odor stronger and less hygienic, but also makes the stool sample very easily contaminated during the inspection process, making it impossible to ensure the authenticity and accuracy of the routine stool test results.

[0003] Currently, a Chinese patent application with publication number CN108303282A discloses a stool collector capable of controlling the amount of feces collected. However, the patent uses an aluminum foil sealing film, so leakage may occur during detection due to multiple punctures of the aluminum foil sealing film.

[0004] Therefore, the applicant has found a solution to the above-mentioned problem through beneficial exploration and research. The technical solution to be introduced below is produced in this context. Utility Model Content

[0005] The technical problem to be solved by the present invention is to provide a urine sampling device that prevents leakage after puncture in order to solve the above problems.

[0006] The technical problem to be solved by the present invention can be achieved by adopting the following technical solutions:

[0007] A feces collector that prevents leakage after puncture, comprising a cylinder and a feces collector, characterized in that the inner wall of one end of the cylinder is provided with an internal thread that cooperates with the thread of the feces collector, the other end of the cylinder is provided with a detachable sealing member, the middle part of the cylinder is provided with an inner convex ring, the inner convex ring divides the inner cavity of the cylinder into two independent first cavity and second cavity, the second cavity is provided with a dissolving liquid, one end of the feces collector is provided with a threaded cap that cooperates with the internal thread, and the other end of the feces collector is provided with a collection head that passes through the inner convex ring and extends into the second cavity and has a thorn-shaped structure.

[0008] In a preferred embodiment of the present invention, a sealing tube is provided in the first cavity to prevent the dissolving liquid in the second cavity from entering.

[0009] In a preferred embodiment of the present invention, a filter is provided in the second cavity, and the filter divides the second cavity into two independent dilution chambers and a sampling chamber.

[0010] In a preferred embodiment of the present invention, the filter is a filter mesh.

[0011] In a preferred embodiment of the present invention, the sealing member is a rubber stopper.

[0012] Due to the adoption of the above technical solution, the beneficial effect of the present invention is that: the present invention has good sealing performance and meets the requirements of the puncture performance of the equipment by adopting the design structure of the rubber stopper, which can solve the problem of leakage of the aluminum foil seal after multiple punctures during testing, and can effectively reduce the pollution of the air environment in the testing room. In addition, when the equipment fails, the tester can also easily remove the rubber stopper and take out the dissolving liquid for testing. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the following briefly introduces the drawings required for use in the embodiments or the description of the prior art. Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative work.

[0014] Figure 1 It is a structural diagram of the present utility model. DETAILED DESCRIPTION

[0015] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0016] See also Figure 1 The feces collecting device shown in the figure is leak-proof after puncture and comprises a barrel 100 and a feces collecting device 200 .

[0017] The inner wall of one end of the barrel 100 is provided with an internal thread 100a that threads into the feces sampling device 200. The other end of the barrel 100 is provided with a removable seal 300. The middle portion of the barrel 100 is provided with an inner convex ring 110, which divides the inner cavity of the barrel 100 into two independent first and second cavities 120 and 130. The second cavity 130 is provided with a dissolving solution. The seal 300 in this embodiment is preferably a rubber stopper.

[0018] One end of the fecal sampler 200 is provided with a threaded cap 210 that matches the internal thread 100a. The threaded cap 210 is connected to the barrel 100 through threads. This structure not only effectively improves the stability between the sampling rod 200 and the barrel 100, but also effectively prevents liquid leakage.

[0019] A collecting head 220 is provided at the other end of the feces collector 200. The collecting head 220 has a thorn-like structure and passes through the inner convex ring 300 and extends into the second cavity 130. This structure can effectively control the amount of feces collected, which is convenient for quantitative detection of clinically related diseases or diagnostic markers.

[0020] A sealing tube 400 is provided in the first mold cavity 120 to prevent the dissolving liquid in the second mold cavity 130 from entering. Specifically, the sealing tube 400 is sleeved on the feces sampler 200 and is close to the side of the inner convex ring 110. The sealing tube 400 is installed in the middle diameter reducing portion of the feces sampler to prevent the dissolving liquid from entering the other mold cavity.

[0021] A filter 500 is provided in the second cavity 130, and the filter 500 divides the second cavity 130 into two independent dilution chambers 131 and sampling chambers 132. The filter 500 in this embodiment is preferably a filter mesh.

[0022] The working principle of this utility model is as follows:

[0023] When sampling and testing the patient's stool, the threaded cap 210 is rotated and removed from the barrel 100, and then the thorn-shaped collection head 220 of the sampling rod 200 is used to sample. After the sampling is completed, the collection head 220 is inserted into the dilution chamber 131 through the inner convex ring 110, and the threaded cap 210 is rotated and locked on the barrel 100 through the threaded connection. After the stool is diluted in the dilution chamber 131, it flows into the sampling chamber 132 through the filter 500. When the medical staff conducts the test, they only need to remove the rubber stopper 300 for sampling and testing.

[0024] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in this invention is defined by the appended claims and their equivalents.
