Abstract

The invention provides a suction device, and relates to the technical field of medical instruments. The suction device comprises a test tube, a sealing plug, a suction tube, a first valve and a needle head; the sealing plug is used for sealing a tube opening of the test tube, and the interior of the test tube is in a negative pressure state; one end of the suction tube is connected with the needle head, and the other end of the suction tube penetrates through the sealing plug and is located in the test tube; and the first valve is arranged on the suction tube, and the first valve is located outside the test tube. According to the suction device, the test tube is arranged to be a sealed tube body, structures such as a piston rod are not arranged, the interior of the suction device is in the negative pressure state, and when puncture suction is carried out, the suction tube can be controlled to be in a switch-on or switch-off state only by one medical worker; when the suction tube is in the switch-on state, due to the fact that the interior of the test tube is in the negative pressure state, under the action of the pressure difference, the test tube can automatically suck tissue fluid such as the testis, the suction of the testis tissue fluid can be realized by one person, the fear and worry of a patient are relieved to a certain extent, the comfort degree of the patient is improved, and the working efficiency of the medical worker is improved.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a suction device. Background technique [0002] In the field of men's health treatment, when a man has infertility symptoms, it is necessary to perform a testicular puncture in the outpatient clinic, and use a testicular tissue suction device to extract the testicular tissue in the testis to better assist doctors in disease detection and treatment. [0003] Existing testicular suction devices mostly use a syringe, which is connected to a needle at the front end of the syringe, and the needle is inserted into the testis of the patient, and the tissue fluid is extracted from the testis of the patient by pulling the piston rod of the syringe so that the interior of the syringe is under negative pressure . [0004] However, when extracting the existing syringe, two hands are required to operate, one hand holds the syringe body, and the other hand gradually pulls the piston...
