[0024] Please refer to Figures 1-5 .

[0025] The present application provides a kind of blood sampling protective sleeve technical scheme: a kind of blood sampling protective sleeve, including combination blood sampling needle 1 of being composed of communication pipe 101, blood sampling needle head 102, connecting column 103 and collection needle 104, still include: the protective assembly 2 of being arranged at the one end of collection needle 104, including the protective sleeve 201 of being set in the one end of connecting column 103 and the annular sleeve 202 of being set in the outer lateral wall of collection needle 104 and the buckle 203 of being symmetrically arranged in the outer lateral wall of annular sleeve 202, to protect collection needle 104 and ensure that it does not deviate when being connected with blood sampling test tube.

[0026] The communication pipe 101, the blood sampling needle head 102, the connecting column 103 and the collection needle head 104 are in communication with each other, and this arrangement is a common technical means of the combined blood sampling needle 1 in the prior art, which will not be described in detail here; by arranging the protective sleeve 201, the annular sleeve 202 and the buckle 203, the protective sleeve 201 is used to protect the collection needle head 104 from being damaged by external factors, the annular sleeve 202 is used to ensure that the collection needle head 104 will not be offset when it is connected with the blood sampling tube, the buckle 203 is used to stably connect the blood sampling tube and the collection needle head 104, which will not easily be separated by external force, effectively improving the safety and stability of the combined blood sampling needle 1 in actual clinical use, and ensuring the safety of medical staff during use.

[0027] In an embodiment, the protective sleeve 201 is cylindrically arranged and one end thereof is fixedly arranged at one end of the connecting column 103, and the inner side wall of the protective sleeve 201 is provided with symmetrically arranged grooves.

[0028] In this way, the protective sleeve 201 is arranged to protect the collection needle head 104 from the one end of the connecting column 103, and the length of the protective sleeve 201 is the same as the length of the blood sampling tube for collecting blood, so that the collection needle head 104 and the blood sampling tube can be protected at the same time, and the grooves are arranged to enable the buckle 203 to slide up and down in the grooves and to slightly rotate in the grooves.

[0029] In an embodiment, the inner side wall of the annular sleeve 202 is in sliding contact with the outer side wall of the collection needle head 104, the outer side wall of the annular sleeve 202 is fixedly provided with symmetrically arranged protrusions, one end of the buckle 203 is rotatably arranged on the protrusions of the annular sleeve 202, and a torsion spring 204 is fixedly arranged between one end of the buckle 203 and the protrusions of the annular sleeve 202.

[0030] In this way, the annular sleeve 202 is sleeved on the outer wall of the collection needle 104. When it is required to insert one end of the collection needle 104 into the blood collection tube, first, the end of the blood collection tube is aligned with the lower end of the protective sleeve 201, and then the side wall of the protective sleeve 201 is pinched and pressed downward to move. At this time, the slope surface on the hook portion of the lower end of the buckle 203 will first contact the cover on the blood collection tube, and the cover will be extruded to make the buckle 203 deviate in the direction away from each other, and at the same time, the collection needle 104 will also be inserted into the blood collection tube. At this time, the annular sleeve 202 will be moved to one end by the end surface of the blood collection tube. When it is moved to the end of one end, the blood collection tube is completely inserted into the protective sleeve 201, and the annular sleeve 202 cannot continue to move to one end. After the cover of the blood collection tube slides to the bottom end of the cover, the buckle 203 loses the contact between the cover, and at this time, the buckle 203 will restore to the initial vertical position under the action of the counterforce of the torsion spring 204. At this time, one end of the buckle 203 will clamp the cover of one end of the blood collection tube, so that it cannot be pulled out from the other end at will.

[0031] In an embodiment, the upper end of the protective sleeve 201 is slidably provided with a moving column 206 symmetrically arranged and penetrating through the side wall thereof. One end of the moving column 206 is fixedly provided with a pressing block 205. One side surface of the pressing block 205 is fixedly provided with a telescopic spring 207 symmetrically arranged. The other end of the telescopic spring 207 is fixedly arranged on the outer side wall of the protective sleeve 201. One end of the buckle 203 close to the annular sleeve 202 is fixedly provided with a protrusion 208. The other end of the buckle 203 away from the annular sleeve 202 is provided with a hook. One side surface of the buckle 203 is matched with a groove opened in the inner side wall of the protective sleeve 201.

[0032] In this way, when it is required to release the connection between the end of the collection needle 104 and the blood collection tube, the pressing block 205 is pressed at the same time. The pressing block 205 will drive the moving column 206 at one end to move in the direction of approaching each other. At this time, the telescopic spring 207 is contracted. When the moving column 206 moves to contact the protrusion 208 at one end of the buckle 203, the pressing block 205 is continuously pressed, and the pressing block 205 continuously moves to drive the moving column 206 to continuously move. At this time, the moving column 206 will drive the buckle 203 to slightly overturn by contacting the protrusion 208. At this time, the distance between the hook portion at the other end of the buckle 203 and the outer side wall of the blood collection tube is increased. The buckle 203 will not clamp the cover portion of the blood collection tube. At this time, the blood collection tube and the collection needle 104 can be quickly separated.

[0033] It is apparent for a person skilled in the art that the present application is not limited to the details of the above-described exemplary embodiments, but that it can be implemented in other concrete forms without departing from the spirit or the essential characteristics of the present application. Therefore, the embodiments should be considered in all respects as illustrative and not restrictive, the scope of the present application being defined by the appended claims rather than the above description, and all changes coming within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
