Description

Technical Field

[0001] The utility model belongs to the technical field of medical appliances, and in particular relates to a device for removing a cap from a blood collection tube used in a laboratory. Background Art

[0002] The laboratory department is a bridge between clinical medicine and basic medicine. It is a comprehensive laboratory diagnosis department that integrates medical testing, teaching, and scientific research. It can only mainly test patient specimens collected by various departments. However, due to the influence of many factors, the laboratory department is also one of the departments with a high incidence of hospital infections. For example: when the laboratory staff tests blood specimens, they need to remove the tube cap on the blood collection tube and then draw blood for testing. In the process of removing the tube cap, the laboratory staff may directly contact the blood, resulting in cross infection, threatening the life and health of the laboratory staff.

[0003] According to the Chinese patent document with announcement number CN221141163U, a blood collection tube cap removal device for a laboratory department comprises a base arranged at the bottom and a vertical plate arranged at one end of the base, and also comprises a clamping tube, a slot, a tube slot, a cap slot and a cap removal slot, a clamping tube is fixed on the top of one end of the base, a plurality of slots are opened on the top of the clamping tube, an external thread is opened on the outer side of the top of the clamping tube, a fastening threaded tube is screwed on the external thread, and a plurality of rotating rods are fixed on the surface of the fastening threaded tube; a groove is opened in the middle of the vertical plate, a lever is installed in the middle of the groove through a rotating shaft, a grip is arranged at one end of the lever, a ferrule is fixed at the other end of the lever, a tube slot is opened in the middle of the bottom end of the ferrule, and a cap slot is opened on the ferrule above the tube slot. The utility model has a novel structure and an ingenious conception, is suitable for the inspection of a large number of blood samples in the laboratory department, avoids direct contact between the operator's hands and the blood sample, and causes the risk of cross infection, and secondly, saves time and effort when removing the cap, which is convenient for use.

[0004] Based on the search of the above patents and in combination with the equipment in the prior art, it is found that when the above equipment is used, although the tube caps on each blood collection tube can be removed by using the lever principle, when the lever is pushed toward each tube cap in turn and all the tube caps are located inside the cap groove, the front end of the lever will contact all the tube caps in turn, and the front end of the inner top wall of the cap removal groove will also contact the upper ends of all the tube caps in turn, which may contaminate other blood collection tubes during the movement of the lever. There may also be potential infection risks. Cross-contamination will spread pathogens and pose a potential infection risk to personnel who subsequently contact the samples. Moreover, when the tube caps on multiple blood collection tubes are removed by using the lever principle, since the movement of the lever is an arc-shaped rotation with the lever point as the midpoint, the removal force on the multiple tube caps may be uneven, and some tube caps may not be successfully removed, and may even damage the blood collection tube or cause internal sample leakage.

[0005] Therefore, it is urgent to improve the cap-removing device for blood collection tubes used in the laboratory to solve the above-mentioned problems. Utility Model Content

[0006] In view of the above problems, the purpose of the utility model is to provide a blood collection tube cap removal device for laboratory use, which can avoid contact between blood collection tubes during sample testing, reduce the possibility of cross contamination, and can smoothly remove multiple tube caps.

[0007] To achieve the above objectives, the utility model adopts the following technical solution: a blood collection tube cap removal device for a laboratory, comprising a telescopic detection frame and a cap removal ring, a plurality of tube insertion grooves being equidistantly provided on an inner bottom surface of the telescopic detection frame, the tube insertion grooves being used to place blood collection tubes, a fixing assembly being provided on the telescopic detection frame for clamping and fixing the blood collection tubes, the cap removal ring being provided at the upper end of the telescopic detection frame, the top of the cap removal ring extending to the outside of the telescopic detection frame, the number of the cap removal rings being multiple, the multiple cap removal rings being arranged in one-to-one correspondence with the positions of the multiple tube insertion grooves, the circumferential inner diameter of the cap removal ring being larger than the circumferential outer diameter of the tube cover, at least one slide groove being provided on the inner wall of the cap removal ring, a limit block being slidably connected in the slide groove, and a spring being connected between the limit block and the inner wall of the slide groove.

[0008] The beneficial effects of the utility model are as follows: by placing a plurality of blood collection tubes into a plurality of separate tube insertion slots respectively, and then clamping the blood collection tubes with a fixing assembly to keep them in a vertical state and fix them, the telescopic detection frame moves downward, and the tube cover squeezes the limit block to enter the slide slot; when the bottom of the tube cover is located above the limit block, the telescopic detection frame moves upward, and the tube cover is pulled off under the limiting action of the limit block, thereby avoiding contact between the blood collection tubes, reducing the possibility of cross contamination, and multiple tube covers can be pulled out smoothly.

[0009] In order to clamp and fix the blood collection tube;

[0011] The beneficial effect of this improvement is that after the blood collection tube is inserted into the tube insertion slot, the telescopic detection frame is prevented from pulling out the blood collection tube as a whole when the tube cover is removed. By starting the motor, the output end of the motor drives the rotating rod to rotate, and the rotation of the rotating rod drives the gear to rotate. The gear drives the two gear rods to move in relative directions or opposite directions. At the same time, one end of the gear rod slides on one of the connecting rods, and the other end of the gear rod drives the other connecting rod fixedly connected to it to move inside the slide rail, thereby driving the clamping part to move. At this time, the two clamping parts clamp and fix the blood collection tube in relative directions at the same time, or loosen the blood collection tube in opposite directions. When the blood collection tube is clamped and fixed, the blood collection tube can be prevented from being pulled out as a whole when the tube cover is removed, and the blood collection tube can be conveniently taken out of the blood collection tube from the tube insertion slot.

DETAILED DESCRIPTION

[0034] In order to enable those skilled in the art to better understand the technical solution of the utility model, the utility model is described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the protection scope of the utility model.

[0035] like Figure 1-6 As shown, a capping device for blood collection tubes used in a laboratory comprises a telescopic detection frame and a capping ring 4. A plurality of tube insertion grooves 2 are equidistantly provided on the inner bottom surface of the telescopic detection frame, and the tube insertion grooves 2 are used to place blood collection tubes 3. A fixing assembly for clamping and fixing the blood collection tubes 3 is provided on the telescopic detection frame. The capping ring 4 is provided at the upper end of the telescopic detection frame, and the top of the capping ring 4 extends to the outside of the telescopic detection frame. There are a plurality of capping rings 4, and the plurality of capping rings 4 are arranged in a one-to-one correspondence with the positions of the plurality of tube insertion grooves 2. The circumferential inner diameter of the capping ring 4 is larger than the circumferential outer diameter of the tube cover. At least one slide groove 5 is provided on the inner wall of the capping ring 4, and a limit block 6 is slidably connected in the slide groove 5. A spring 7 is connected between the limit block 6 and the inner wall of the slide groove 5.

[0036] When the tube cover 3 is in the bottle, the bottle cap 3 is put into the bottle and the bottle cap is put into the bottle.

[0037] Preferably, the fixing assembly includes two symmetrically arranged clamping parts 801, two moving rods 802, two connecting rods 803, two symmetrically arranged toothed rods 804, and a gear 805. A receiving groove 9 is provided at the bottom of the telescopic detection frame, and a plurality of symmetrically arranged slide rails 10 are provided at the lower end of the telescopic detection frame. The plurality of slide rails 10 are respectively located on both sides of the intubation groove 2 and are connected to the receiving groove 9. The clamping part 801 is located on the inner top surface of the telescopic detection frame, the bottom of the clamping part 801 is connected to the moving rod 802, the moving rod 802 is slidably connected to the inside of the slide rail 10, the bottom of the moving rod 802 extends to the inside of the receiving groove 9 and is connected to the connecting rod 803, one end of the two toothed rods 804 is respectively slidably connected to the two connecting rods 803, the other ends of the two toothed rods 804 are respectively connected to the two connecting rods 803, the gear 805 is meshed between the two toothed rods 804, and the gear A rotating rod 11 is provided at the bottom of 805, and a motor 12 is connected to the bottom of the rotating rod 11. When the blood collection tube 3 is inserted into the tube insertion slot 2, the telescopic detection frame is prevented from pulling out the blood collection tube 3 as a whole when the tube cover is removed. By starting the motor 12, the output end of the motor 12 drives the rotating rod 11 to rotate, and the rotation of the rotating rod 11 drives the gear 805 to rotate. The gear 805 drives the two gear rods 804 to move in relative directions or opposite directions. At the same time, one end of the gear rod 804 slides on one of the connecting rods 803, and the other end of the gear rod 804 drives the other connecting rod 803 fixedly connected to it to move inside the slide rail 10, thereby driving the clamping part 801 to move. At this time, the two clamping parts 801 clamp and fix the blood collection tube 3 in relative directions at the same time, or loosen the blood collection tube 3 in opposite directions. When the blood collection tube 3 is clamped and fixed, the blood collection tube 3 can be prevented from being pulled out as a whole when the tube cover is removed, and the blood collection tube 3 can be conveniently taken out of the tube insertion slot 2.

[0038] Preferably, a limiting ring 13 is provided above the capping ring 4, and the circumferential inner diameter of the limiting ring 13 is smaller than the circumferential outer diameter of the tube cover. A tension spring 14 is connected between the limiting ring 13 and the capping ring 4. When the tube cover is removed, the tube cover may bounce up due to the sudden release of pressure inside the test tube. When the tube cover is located inside the capping ring 4, the limiting ring 13 conflicts with the tube cover. When the tube cover bounces up, the tube cover is limited inside the capping ring 4 under the limiting action of the limiting ring 13. When the tube cover is taken out, the limiting ring 13 is pulled up. At this time, the tension spring 14 is deformed, and the distance between the limiting ring 13 and the capping ring 4 is increased, which facilitates the removal of the tube cover from the distance between the two. In addition, since the limiting ring 13 is an annular structure, the contact area with the tube cover can be reduced, thereby reducing contamination to the limiting ring 13.

[0039] Preferably, a splash-proof ring 15 is provided at the bottom of the capping ring 4. When the tube cover is pulled out, due to the pressure inside the blood sampling tube 3 or a small amount of blood remaining on the inner wall of the tube cover, a small amount of blood may splash out, thereby contaminating other external objects. At this time, the provision of the splash-proof ring 15 can avoid blood splashing in advance, reducing the possibility of contamination.

[0040] Preferably, the capping ring 4 is detachably connected to the upper end of the telescopic detection frame, wherein the capping ring 4 and the telescopic detection frame can be connected by means of threads, clamping, etc. After the specimen inspection in the blood collection tube 3 is completed, the capping ring 4 can be removed from the telescopic detection frame. At this time, the capping ring 4, the limit ring 13 and the splash-proof ring 15 are all removed together, and then cleaned and disinfected, and then the capping ring 4 is installed for next use.

[0041] Preferably, a friction ring 16 is provided on the inner wall of the tube insertion groove 2, wherein the friction ring 16 can be made of rubber, silicone or other materials. After the blood collection tube 3 enters the tube insertion groove 2, the blood collection tube 3 is kept in a vertical state under the squeezing action of the friction ring 16, so that when the tube cover is pulled out, the tube cover can accurately enter the splash-proof ring 15 and then enter the interior of the cover removal ring 4.

[0042] Preferably, the telescopic detection frame includes a base 101, telescopic legs 102 connected to the upper end of the base 101, and a top plate 103 connected to the top of the telescopic legs 102, wherein the telescopic legs 102 can be electric telescopic rods, hydraulic telescopic rods, etc., and the base 101 provides a certain stability for the whole. The telescopic legs 102 can be telescoped up and down, driving the top plate 103 to telescope up and down, which is convenient for pulling out the pipe cover and facilitating the use of the device.

[0043] The working principle and use process of the utility model are as follows: when using the device, firstly, a plurality of blood collection tubes 3 are respectively placed into a plurality of cannula slots 2. At this time, the friction ring 16 squeezes and fixes the blood collection tubes 3 to keep the blood collection tubes 3 in a vertical state, and then the motor 12 is started, and the output end of the motor 12 drives the rotating rod 11 to rotate, and the rotation of the rotating rod 11 drives the gear 805 to rotate, and the gear 805 drives the two gear rods 804 to move in relative directions or opposite directions. At the same time, one end of the gear rod 804 slides on one of the connecting rods 803, and the other end of the gear rod 804 drives the other connecting rod 803 fixedly connected thereto to move inside the slide rail 10, thereby driving the clamping part 801 to move. At this time, the two clamping parts 801 clamp and fix the blood collection tubes 3 in relative directions at the same time, or loosen the blood collection tubes 3 in opposite directions. After the blood collection tubes 3 are clamped and fixed, the telescopic legs 102 drive The top plate 103 moves downward, allowing the tube covers to enter the splash guard in turn, and squeezes the inclined surface of the limit block 6 to squeeze the limit block 6 into the inside of the slide groove 5. When the tube cover completely enters the inside of the capping ring 4, the plane on the limit block 6 contacts the tube cover under the elastic action of the spring 7, and the tube cover is limited. Then the telescopic legs 102 drive the top plate 103 to move upward to pull out the tube cover. At the same time, the limit ring 13 and the splash guard ring 15 respectively avoid splash pollution of the tube cover and blood. Finally, the limit ring 13 is pulled up, and the tension spring 14 is deformed at this time. The distance between the limit ring 13 and the capping ring 4 is increased, which is convenient for taking out the tube cover from the distance between the two. In addition, the limit ring 13, due to its annular structure, can reduce the contact area with the tube cover, reduce the pollution of the limit ring 13, and avoid contact between the blood collection tubes 3 during sample testing, reduce the possibility of cross contamination, and can smoothly pull out multiple tube covers.
