Technical Field

[0001] The utility model relates to the technical field of medical devices, and more specifically, the utility model relates to a sample sampling device for medical detection. Background Art

[0002] Medical detection is a science that conducts tests on materials taken from the human body in aspects such as microbiology, immunology, biochemistry, genetics, hematology, biology, cytology, etc., so as to provide information for the prevention, diagnosis, and treatment of human diseases and the evaluation of human health. Medical devices refer to instruments, equipment, appliances, materials, or other articles used alone or in combination on the human body, and also include the required software. Medical devices are the most basic elements for medical treatment, scientific research, teaching, institutions, and clinical disciplines, including both professional medical devices and household medical devices.

[0003] After collecting the samples that need to be detected from patients, medical staff need to conduct tests on the collected samples. During the testing process, the samples need to be taken out for testing. Currently, generally, sampling is carried out through a dropper. This method of sampling through a dropper is prone to dripping during the sampling process and is not convenient for people to use. After sampling is completed, it is impossible to ensure that it is at room temperature and the temperature is likely to change, which may affect the test results. Summary of the Utility Model

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a sample sampling device for medical detection, which has the advantages that the sample is not easy to drip and can be stored at room temperature.

[0005] To achieve the above object, the present utility model provides the following technical solutions: A sample sampling device for medical detection, including a housing main body. Inside the housing main body, there is a collection cylinder. At the central position inside the collection cylinder, there is a push rod. A piston is fixedly connected to the lower surface of the push rod. The lower surface of the collection cylinder is fixedly connected to a conical cylinder.

A heat conducting sheet 22 is fixedly installed on the lower part of the inner surface of the housing main body 1.

[0023] Through the mutual cooperation of the first thread groove 9 and the adjustment assembly 8, the adjustment assembly 8 can adjust its position by moving up and down in a threaded manner.

[0024] Among them, the adjustment assembly 8 includes a first nut 801. The first nut 801 is threadedly connected to the first thread groove 9. An equal number of first springs 802 are fixedly connected to the lower surface of the first nut 801. A gasket 803 is fixedly connected to the lower surface of the first spring 802.

[0025] By moving the adjustment assembly 8 up and down, the collection cylinder 2 is pushed to move up and down, thereby opening and closing the conical cylinder 5.

[0026] Among them, the piston 4 is arranged inside the collection cylinder 2. The outer side of the piston 4 is made of silica gel.

[0027] The sample can be sampled by the up and down movement of the piston 4. The outer material of the piston 4 is silica gel, which can closely adhere to the inner wall of the collection cylinder 2 to prevent air leakage.

[0036] The working principle and usage process of the present utility model:

[0037] When the medical test sample sampling device is in use, when sampling is required, by adjusting the third adjusting nut 19, it is disengaged from the card slot 16 and enters the sliding slot 18. Through the up and down adjustment of the adjusting component 8, the collection cylinder 2 is pushed to move up and down. When the adjusting component 8 moves downward, the collection cylinder 2 moves downward, and the outer shell main body 1 drives the mounting column 13 and the tapered block 12 to move upward through the L-shaped rod 15, and the second spring 14 is compressed. The tapered cylinder 5 opens for sampling. Pull the push rod 3 to drive the piston 4 to move upward, and the sample enters the collection cylinder 2 through the suction force from the feed pipe 6. When the sampling is completed, the adjusting component 8 moves upward, the second spring 14 resets, the outer shell main body 1 drives the mounting column 13 and the tapered block 12 to move downward through the L-shaped rod 15, and the tapered cylinder 5 closes. Adjust the third adjusting nut 19 to fix it in the card slot 16, which prevents the possibility of sample dripping after sampling and is convenient for people to use. At the same time, to prevent the sample temperature from changing too much, turn on the constant temperature heating device 20 to perform a constant temperature treatment on the inside of the collection cylinder 2 through the heat conduction sheet 22, so as to prevent the sample temperature from changing and perform a constant temperature treatment, and prevent the problem of inaccurate test results caused by the sample temperature problem.
