Description

Technical Field

[0001] The utility model relates to the field of medical auxiliary equipment, in particular to a test tube cap removal device. Background Art

[0002] Orsendo's fully automatic blood type analyzer is a commonly used blood transfusion compatibility test instrument in the domestic blood transfusion department. Its sample requirements are usually 3ml EDTA anticoagulant blood vessels (vacuum test tubes). After the vacuum test tubes are sampled and centrifuged, they will be placed on Orsendo's special test tube rack and then tested on the machine. During this operation, medical staff are often required to manually remove the caps. When there are a large number of vacuum test tubes, the cap removal process is troublesome, time-consuming and laborious. The existing cap removal instruments have relatively high costs and are not economical; and the vacuum test tubes have a small volume (3ml). After the centrifuge caps are removed and placed on the test tube rack, it is easy to cause the specimen to splash, which poses a certain biosafety risk. Utility Model Content

[0029] The embodiments of the present utility model will be further described below in conjunction with the accompanying drawings.

[0030] Example:

[0031] A test tube cap removal device, comprising:

[0032] The fixing plate 10, such as Figure 1 and Figure 5 As shown, eight clamping strips 11 are arranged in sequence on one side of the fixing plate 10, the two clamping strips 11 located on the outermost sides are short strips, and a clamping space 12 is formed between two adjacent clamping strips 11. The width of the clamping space 12 is slightly smaller than the outer diameter of the test tube body 32, and is used to clamp the test tube body 32;

[0033] The cap removal plate 20, such as Figure 2 and Figure 6 As shown, eight uncapping strips 21 are arranged in sequence on one side of the uncapping plate 20, and the eight uncapping strips 21 correspond to the eight clamping strips 11 one by one. A uncapping space 22 is formed between two adjacent uncapping strips 21, and the width of the uncapping space 22 is greater than the outer diameter of the test tube body 32 and smaller than the outer diameter of the test tube cap 31.

[0034] In another embodiment, if Figure 5 and Figure 6As shown, a positioning slide post 13 is provided on the top of the fixed plate 10, and a positioning hole 23 cooperating with the positioning slide post 13 is provided on the cap removal plate 20. Through the cooperation between the positioning slide post 13 and the positioning hole 23, it is convenient to quickly complete the alignment and positioning between the fixed plate 10 and the cap removal plate 20.

[0035] In another embodiment, if Figure 2 and Figure 6 As shown, a handle 24 is provided on the top of the uncapping plate 20 to facilitate lifting the uncapping plate 20 for uncapping operations.

[0036] In another embodiment, if Figure 1 and Figure 5 As shown, a handle 14 is provided on one side of the fixing plate 10 away from the clamping strip 11 . The handle 14 is a movable structure, which facilitates pulling out the fixing plate 10 after the cap removal operation is completed.

[0037] In another embodiment, if Figure 6 As shown, the thickness of the uncapping strip 21 gradually decreases from its rear end to the front end, which makes it easy to insert the uncapping plate 20 and the fixing plate 10 into the gap between the test tube cap 31 and the top surface of the test tube rack, and the test tube cap 31 can be pre-tilted for uncapping (at the same time, the length of the clamping strip 11 can be set longer than the length of the uncapping strip 21, so as to achieve clamping first and then tilting, and avoid the vacuum test tube 30 being tilted as a whole), making the entire uncapping process smoother.

[0038] In another embodiment, if Figure 4 As shown, a splint 25 is provided at the uncapping point of each uncapping space 22 on the uncapping plate 20. The splint 25 is an arc-shaped open-loop structure. The splint 25 is made of elastic material. The inner diameter of the splint 25 is adapted to the outer diameter of the test tube cap 31. The opening width of the splint 25 is slightly smaller than the outer diameter of the test tube cap 31. When the uncapping plate 20 is inserted, the test tube cap 31 can be clamped by utilizing the elastic deformation of the splint 25. After the uncapping plate 20 is lifted to complete the uncapping operation, the test tube cap 31 will be clamped in the splint 25, which is convenient for resetting and capping multiple test tube caps 31 at one time, thereby improving the operating efficiency and avoiding the mismatching of the test tube caps 31 after being randomly placed.

[0039] In another embodiment, if Figure 1As shown, the two clamping strips 11 constituting the even-numbered clamping spaces 12 (the 2nd, 4th, and 6th clamping spaces 12) are arranged tilted toward each other. Since the vacuum test tubes 30 on the Osendo test tube rack are arranged in two rows staggered front and back, the odd-numbered clamping spaces 12 clamp the vacuum test tubes 30 in the outer row, and the clamping point is located at the rear end of the clamping strip 11, and the even-numbered clamping spaces 12 clamp the vacuum test tubes 30 in the inner row, and the clamping point is located at the rear end of the clamping strip 11. The front end of the inner row of vacuum test tubes 30 is tilted toward each other, so that the two clamping strips 11 for clamping the inner row of vacuum test tubes 30 are arranged to be more conducive to clamping the vacuum test tubes 30. At the same time, since the two rows of vacuum test tubes 30 on the Orsendo test tube rack are staggered front and back, after the fixing plate 10 is inserted into place and the clamping operation is completed, the same clamping strip 11 will be subjected to the opposite forces of the inner row of vacuum test tubes 30 and the outer row of vacuum test tubes 30 on both sides thereof, which is more conducive to the clamping operation of all vacuum test tubes 30.

[0040] The test tube uncapping device of the utility model can be specially used for the uncapping operation of the vacuum test tubes 30 stored on the test tube rack of the Orsendo fully automatic blood type analyzer, and its uncapping principle is the same as that of the existing uncapping plate 20. Specifically, when in use, firstly, the uncapping plate 20 is fitted with the fixed plate 10 through the cooperation and positioning of the positioning hole 23 on the uncapping plate 20 and the positioning slide column 13 on the fixed plate 10, and then the clamping space 12 of the fixed plate 10 (the uncapping space 22 of the uncapping plate 20) is aligned with each vacuum test tube 30 on the Orsendo test tube rack, and the fitted uncapping plate 20 and the fixed plate 10 are inserted into the gap between the bottom surface of the test tube cap 31 of the vacuum test tube 30 and the top surface of the Orsendo test tube rack. After being inserted into place, each group of clamping strips 11 of the fixed plate 10 can clamp and fix the test tube body 32 of each vacuum test tube 30 respectively. At this time, the state is as follows: Figure 3 As shown, the cap-removing plate 20 is lifted by the handle 24, and the cap-removing strip 21 on the cap-removing plate 20 is used to remove the test tube caps 31. Multiple vacuum test tubes 30 can be removed at the same time in one operation, which effectively improves the operation efficiency. The cap-removing process is shown in FIG. Figure 7 and Figure 8 In addition, the clamping plate 25 on the cap removal plate 20 can clamp the test tube caps 31, so as to facilitate the reset and capping of multiple test tube caps 31 at one time, thereby improving the operation efficiency and avoiding the mismatching of the test tube caps 31 after they are randomly placed.

[0041] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
