Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a fungal sampling device. Background Technique

[0002] Dermatology is a branch of medicine that focuses on the diagnosis, treatment, and prevention of skin diseases and related problems. This includes common skin problems such as eczema, acne, rashes, skin infections, and more serious diseases such as skin cancer. For patients with skin diseases caused by fungal infections, sampling tests are required to confirm the cause and avoid misdiagnosis.

[0003] Currently, when sampling the skin, a scraper is usually used to scrape the skin in the infected area. During the scraping process, skin debris is not easy to collect and is prone to falling off, which not only affects the sampling efficiency, but also if others come into contact with the fallen debris, it is easy to cause skin infections, increasing the risk of disease transmission. Content of the Utility Model

[0004] The purpose of the utility model is to provide a fungal sampling device that is convenient for collecting skin samples and avoids the falling of samples.

[0005] To achieve the above purpose, the technical solution of the utility model is as follows.

[0006] A fungal sampling device includes a handle and a collection bottle. An installation groove is opened at the bottom of the handle, an installation block is arranged inside the installation groove, a scraper is installed on the outer surface of the installation block, a jack is opened on the side surface of the installation block, and an installation mechanism capable of being inserted and matched with the jack is arranged on the outer surface of the handle. A groove is opened on one side surface of the handle away from the installation mechanism, a negative pressure tube is arranged inside the groove, a sector-shaped suction nozzle is installed at one end of the negative pressure tube, and the sector-shaped suction nozzle is arranged outside the cutting edge of the scraper. A connection end is installed at the other end of the negative pressure tube, and the connection end is adapted to the upper end of the collection bottle. A connection tube is installed at the lower end of the collection bottle, a filter screen is arranged inside the connection tube, and an exhaust fan is installed on the outer surface of the handle through a lifting mechanism, and the upper end of the exhaust fan is adapted to the connection tube.

[0007] It can be seen that through the setting of the installation mechanism, it is convenient to replace the scraper, thus avoiding the situation of cross-infection caused by the repeated use of the scraper. By generating suction with the exhaust fan and acting on the sector-shaped suction nozzle, the skin sample debris scraped by the scraper can be sucked into the collection bottle for collection, which not only improves the sampling efficiency, but also avoids the situation of infecting others due to the falling of the sample. Through the setting of the lifting mechanism, after sampling, the exhaust fan can be driven to move downward, which is convenient for removing the collection bottle and taking it to the inspection department for inspection.

[0008] Further, the installation mechanism includes an inner groove opened inside the handle. A plug rod is inserted into the inner groove. A shoulder is provided on the outer surface of the plug rod. A spring is sleeved on the outer surface of the plug rod, and both ends of the spring abut against the shoulder and the inner wall of the inner groove respectively.

[0009] When replacing the scraper, first pull the plug rod outwards to extract its end from the jack, and then the scraper can be removed. When installing the scraper, first pull the plug rod to drive the contraction of its end, then insert the installation block into the installation groove. When the jack is aligned with the plug rod, the plug rod can be released. Under the elastic force of the spring, the plug rod is inserted into the jack to fix the installation block, thereby realizing the quick replacement of the scraper.

[0010] Further, the lifting mechanism includes two side grooves opened on both side surfaces of the handle. Threaded rods are rotatably installed inside the two side grooves. A nut seat is installed on the outer surface of the threaded rod. An L-shaped connecting plate is installed on the outer surface of the nut seat, and the end of the L-shaped connecting plate is connected to the outer surface of the exhaust fan.

[0011] When sampling a patient, first insert the connecting pipe at the bottom of the collection bottle into the upper end of the exhaust fan, then rotate the threaded rod to drive the nut seat to rise, and drive the exhaust fan to rise through the connection of the L-shaped connecting plate. The exhaust fan drives the collection bottle to rise and makes its upper end insert into the connection end and abut tightly. At this time, both the upper and lower ends of the collection bottle are sealed. Then start the exhaust fan. The suction generated by the exhaust fan can act on the fan-shaped suction nozzle through the collection bottle and the negative pressure pipe, and achieve the purpose of sucking skin sample debris.

[0012] Further, the upper ends of both threaded rods penetrate to the outside of the handle and are provided with a pulley group in a transmission manner. A knob is installed at the upper end of one of the threaded rods.

[0013] Through the setting of the pulley group, when the knob is turned, both threaded rods can be driven to rotate simultaneously, and then the exhaust fan can be driven to lift and lower simultaneously through the two L-shaped connecting plates, improving the stability of the exhaust fan when lifting and lowering.

[0014] Further, a positioning groove is opened inside the installation block, and a positioning rod is installed inside the installation groove, and the positioning rod is adapted to the positioning groove.

[0015] Through the setting of the positioning groove and the positioning rod, when installing the scraper, the installation block can be positioned, thereby improving the accuracy of the docking between the plug rod and the jack.

[0016] Further, a pull block is installed at the end of the plug rod away from the jack, and an anti-slip pad is provided on the outer surface of the pull block.

[0017] Through the setting of the pull block and the anti-slip pad, it is convenient to pull the plug rod outwards and avoid the situation of hand slipping. Description of the Drawings

A groove 105 is formed on one side surface of the handle 100 away from the mounting mechanism 200. A negative pressure pipe 106 is arranged inside the groove 105. One end of the negative pressure pipe 106 is provided with a fan-shaped suction nozzle 112, and the fan-shaped suction nozzle 112 is arranged outside the cutting edge of the scraper 103. The other end of the negative pressure pipe 106 is provided with a connecting end 107, and the connecting end 107 is adapted to the upper end of the collection bottle 108. A connecting pipe 109 is installed at the lower end of the collection bottle 108. A filter screen 111 is arranged inside the connecting pipe 109. An exhaust fan 110 is installed on the outer surface of the handle 100 through a lifting mechanism 300, and the upper end of the exhaust fan 110 is adapted to the connecting pipe 109.

[0026] When in use, the doctor first inserts the connecting tube 109 at the bottom of the collection bottle 108 into the upper end of the exhaust fan 110, and then drives the exhaust fan 110 to rise through the lifting mechanism 300. The exhaust fan 110 drives the collection bottle 108 to rise and inserts the upper end of the collection bottle 108 into the connecting terminal 107. At this time, the upper and lower ends of the collection bottle 108 are sealed to avoid air leakage. Then the exhaust fan 110 is started, and the suction force generated by the exhaust fan 110 acts on the fan-shaped suction nozzle 112. Then the doctor can hold the handle 100 and use the scraper 103 to scrape the patient's skin, and the scraped Skin debris can be sucked into the negative pressure tube 106 through the fan-shaped suction nozzle 112, and then enter the collecting bottle 108 through the negative pressure tube 106, and the filter 111 can intercept the skin debris, so that the skin debris can be collected in the collecting bottle 108. When the sampling is completed, the exhaust fan 110 can be driven down by the lifting mechanism 300 to make the upper end of the collecting bottle 108 be drawn out from the connecting end 107, and then the connecting tube 109 at the bottom of the collecting bottle 108 is drawn out from the upper end of the exhaust fan 110, and then the collecting bottle 108 can be directly taken to the laboratory for inspection.

[0027] Since fungal skin infections are highly contagious, in order to avoid cross infection between patients, the scraper 103 is a disposable item. After sampling the patient, it can be quickly replaced through the installation mechanism 200 to ensure the safety of each patient during sampling.

[0028] Specifically, the mounting mechanism 200 includes an inner groove 201 opened inside the handle 100, a rod 202 is inserted inside the inner groove 201, a shoulder 203 is provided on the outer surface of the rod 202, a spring 204 is sleeved on the outer surface of the rod 202, and the two ends of the spring 204 are respectively in contact with the shoulder 203 and the inner wall of the inner groove 201. When replacing the scraper 103, the rod 202 is first pulled outward to pull its end out of the socket 104, and then the scraper 103 can be removed. When installing the scraper 103, the rod 202 is first pulled to drive its end to contract, and then the mounting block 102 is inserted into the mounting groove 101. When the socket 104 is aligned with the rod 202, the rod 202 can be loosened. Under the elastic force of the spring 204, the rod 202 is inserted into the socket 104 to fix the mounting block 102, thereby realizing the rapid replacement of the scraper 103.
