The fixing clamp body 10 is connected with a first limiting structure 20 and a second limiting structure 30 at one end for clamping an object, the first limiting structure 20 comprises a first clamping rod 21 installed on the first clamping plate 11 and a second clamping rod 22 installed on the second clamping plate 12, the second limiting structure 30 comprises a third clamping rod 31 installed on the first clamping plate 11 and a fourth clamping rod 32 installed on the second clamping plate 12, when the fixing clamp body 10 clamps, the first clamping rod 21 and the second clamping rod 22 form a first clamping ring 23, the third clamping rod 31 and the fourth clamping rod 32 form a second clamping ring 33, and the size of the second clamping ring 33 is larger than that of the first clamping ring 23. Further, the four sides of the first clamping rod 21, the second clamping rod 22, the third clamping rod 31 and the fourth clamping rod 32 are respectively provided with anti-slip patterns, the anti-slip patterns are used for improving friction force between the first clamping ring 23 and the second clamping ring 33, and the sides of the first clamping rod 21, the second clamping rod 22, the third clamping rod 31 and the fourth clamping rod 32 are chamfered.
It should be noted that, the size of the first clamping ring 23 is close to the size of the infusion tube carrying the blood taking needle, the size of the second clamping ring 33 is close to the size of the blood taking bottle, so that when the fixing clamp body 10 is clamped, the first clamping ring 23 clamps the infusion tube carrying the blood taking needle, and the second clamping ring 33 clamps the blood taking bottle, because the first clamping ring 23 and the second clamping ring 33 are connected on the same fixing clamp body 10, the blood taking bottle and the blood taking needle can be limited together, the separation of the blood taking bottle and the blood taking needle is prevented, a nurse can conveniently take other things, and the blood taking needle can not pop out to take the blood taking tube, thereby improving the probability of successful blood taking.
In particular, when the needle is inserted into the blood collection bottle, the medical staff can press the first clamping plate 11 and the second clamping plate 12 at this time, so that the first clamping plate 11 and the second clamping plate 12 rotate in the direction away from each other around the rotating shaft 14, one end of the fixing clamp body 10 for clamping the object is opened, the torsion spring 15 is pressed at this time, and simultaneously, the first limiting structure 20 and the second limiting structure 30 rotate to open along with the first clamping plate 11 and the second clamping plate 12, so that the first clamping ring 23 and the second clamping ring 33 are opened, then the infusion tube carrying the blood collection needle enters the first clamping ring 23 through the opening of the first clamping ring 23, and simultaneously, the blood collection bottle enters the second clamping ring 33 through the opening of the second clamping ring 33, then, the first clamping plate 11 and the second clamping plate 12 are stopped being pressed, at this time, the first clamping plate 11 and the second clamping plate 12 are rotated in the direction approaching to each other by the elastic force recovered by the torsion spring 15, so that the first clamping ring 23 and the second clamping ring 33 are closed, the first clamping ring 23 and the second clamping ring 33 respectively clamp the infusion tube and the blood collection bottle, and the first clamping ring 23 and the second clamping ring 33 are connected to the same fixing clamp body 10, so that the blood collection bottle and the blood collection needle are limited together, separation of the two is prevented, the blood collection needle is prevented from being automatically ejected out, and a medical staff can also make hands to assist a patient difficult to collect blood, such as the patient repeatedly squeeze and adjust blood collection limbs. It will be appreciated that when the first clamping ring 23 and the second clamping ring 33 clamp the infusion tube and the blood collection bottle respectively, the torsion spring 15 is still in a compressed state, so that the torsion spring still has a restoring elastic force, and the first clamping ring 23 and the second clamping ring 33 clamp the infusion tube and the blood collection bottle respectively more tightly, and further the blood collection bottle and the blood collection needle are more stably limited together.
As shown in fig. 3, each of the first clamping plate 11 and the second clamping plate 12 includes a base plate 16, a handle 17, and a clamping portion 18, wherein the handle 17 extends on one end surface of the base plate 16, the clamping portion 18 extends on the other end surface of the base plate 16, the clamping portion 18 is inclined away from the base plate 16, and the handle 17 and the base plate 16 form a step shape.

The handle 17 is shaped like a pan, and the size of the handle 17 is larger than the size of the base plate 16, so that the handle 17 can be conveniently pressed by the arrangement of the pan, and the pressing area of the handle 17 is increased by the arrangement of the size of the handle 17 larger than the size of the base plate 16. The handle 17 is provided with a through hole 171. By providing the through hole 171, on the one hand, friction force can be increased, and on the other hand, the fixing clip for blood collection can be hung up.
As shown in fig. 1, when the first clamping plate 11 and the second clamping plate 12 are connected together, the connecting plates 13 opposite to each other are abutted together in pairs, and the two connecting plates 13 on the first clamping plate 11 and the second clamping plate 12 are always placed one inside the other outside, wherein the connecting plates 13 on the inside are connected with the connecting plates 13 on the outside through the rotating shaft 14.
Further, the second clamping ring 33 has a size of 13mm to 17mm, and the first clamping ring 23 has a size of 3mm to 7mm. In this embodiment, the second clamping ring has a size of 15mm, and the first clamping ring has a size of 5mm. The second clamping ring 33 and the first clamping ring 23 are oval.
In summary, in the fixing clip for blood collection according to the above embodiment of the present utility model, the first clamping plate 11 and the second clamping plate 12 are rotated in the direction approaching to each other by the elastic force recovered by the torsion spring 15, so that the first clamping ring 23 and the second clamping ring 33 are closed, and the first clamping ring 23 and the second clamping ring 33 respectively clamp the infusion tube and the blood collection bottle, and since the first clamping ring 23 and the second clamping ring 33 are connected to the same fixing clip body 10, the blood collection bottle and the blood collection needle can be limited together, the separation of the two can be prevented, the nurse can conveniently take other things, and the blood collection tube can not be ejected by the blood collection needle, thereby improving the probability of successful blood collection.
The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model.
