When in use, the mounting base column on the handle is fixed to the patient by the fixing tape; it is ensured that the needle will not fall off or shift during the blood collection process, thereby improving the comfort and satisfaction of the patient.

[0024] The disposable blood collection needle has a simple structure and an ingenious design. The fixing tape is stored in a tape storage cavity in the handle, which not only can separate the fixing tape from the infusion tube, but also hide the fixing tape in the handle of the blood collection needle, thereby reducing the area exposed to the air and avoiding the risk of cross infection during blood collection. Before blood collection, medical staff do not need to spend time arranging the fixing tape. After the blood collection needle is inserted into the vein, the medical staff only needs to pull out the fixing tape to unfold the fixing tape for use, thereby reducing the number of operating steps, and can promptly fix the blood collection needle on the patient. The blood collection needle will not easily slip or move, thereby improving the success rate and efficiency of blood collection and being easy to use.

[0025] Furthermore, the fixing tape 20 includes a first base film 21 and a release film 22; the front end of the lower surface of the first base film 21 is provided with a first adhesive layer connected to the handle 14, and the tail end is fixedly connected to the connecting piece; wherein the connecting piece can be a glue fixing layer, or a fixing block that fixes the tail end of the fixing tape to the inner bottom surface of the tape storage cavity; the connecting piece is fixedly arranged in the tape storage cavity 141; the first base film 21 is located between the first adhesive layer and the connecting piece and is also provided with a second adhesive layer; the release film 22 is connected to the first base film 21 through the second adhesive layer, and the release film 22 can be connected to the second The first adhesive layer 22 is removed from the second adhesive layer; when the fixing tape 20 is in the storage state, the front end of the fixing tape 20 is fixed to the outside of the handle, the rear end is fixed to the tape fixing cavity in the handle, and the middle part is folded and stored in the tape fixing cavity; when the fixing tape 20 is in use, just tear off the front end of the fixing tape 20 and pull it outwards, so that the fixing tape 20 gradually unfolds outwards from the handle until the fixing tape 20 is straightened, and then tear off the release film 22 on the fixing tape 20, and the blood collection needle can be fixed on the patient by installing the fixing tapes on both sides of the base column; it is easy to use, clean and hygienic. It is worth noting that the first adhesive layer and the second adhesive layer are both adhesive materials commonly used in the prior art.

[0026] Furthermore, the middle part of the fixing tape 20 is folded in sequence along the height direction of the handle 14, placed neatly, and the folds of the fixing tape 20 are not messy; optionally, the overall length of the fixing tape 20 is not less than twice the length of the handle for easy fixation.

[0027] In order to protect the needle, the blood collection needle also includes a needle tube protective sleeve 16 that is detachably connected to the mounting base 11 or the handle 14; the needle is located in the needle tube protective sleeve 16; wherein, the needle tube protective sleeve can adopt a connection structure in the prior art, for example, a plug-in groove is provided on the mounting base or the handle, and the needle tube protective sleeve can be plugged and fixed in the plug-in groove.

[0028] Furthermore, the outward expansion direction of the fixing tape 20 is perpendicular to the length direction of the mounting base column 11, and the connection is stable.

[0029] Embodiment 2:

[0030] The utility model also provides a disposable blood collection needle, which is the same as the first embodiment and is not described in detail. Figure 4 As shown, the fixing tape 20 is rolled up or folded and stored in the tape receiving cavity 141; the connecting member is a rotating shaft 15 rotatably arranged in the tape receiving cavity; the rotating shaft 15 is parallel to the needle tube 12; the fixing tape 20 includes a second base film 23; the lower surface of the second base film 23 is provided with a third adhesive layer, and its connection principle is the same as that of the medical cloth tape in the prior art; the front end of the second base film 23 passes through the through hole 142 and is bonded to the outer surface of the handle 14, and the end is fixedly connected to the rotating shaft 15; the middle part of the fixing tape 20 is rolled up on the rotating shaft 15 with the rotating shaft 15 as the center of the circle.

[0031] When in use, the front end of the fixing tape 20 is torn off and pulled outward, so that the fixing tape 20 moves outward from the handle while driving the shaft to rotate until the shaft stops rotating, and the fixing tape can be used to fix the blood collection needle on the patient, which is easy to operate. It is worth noting that the third adhesive layer can be any adhesive material commonly used in the prior art.

[0032] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the claims attached to the utility model.
