[0034] As Figures 1 to 5As shown in the figure, an embodiment of the present utility model provides a connection fixing clip for a scalp needle and a heparin cap, which includes an upper fixing clip 3 and a lower fixing clip 4. The materials of the upper fixing clip 3 and the lower fixing clip 4 are both transparent plastic materials. One side of the upper fixing clip 3 and the lower fixing clip 4 are both fixedly connected with a pressing plate 10. A fixing groove is formed on the pressing plate 10, and a plurality of reinforcing rods are fixedly connected in the fixing groove. The middle positions of a pair of pressing plates 10 are both rotatably connected with the same connecting shaft 11. A snap spring 12 is sleeved on the connecting shaft 11, and the two ends of the snap spring 12 are respectively abutted against the opposite sides of the pair of pressing plates 10. One side of the upper fixing clip 3 is fixedly connected with a first protective sleeve 5, and one side of the lower fixing clip 4 is fixedly connected with a second protective sleeve 6. The inner walls of the first protective sleeve 5 and the second protective sleeve 6 are both abutted against the indwelling needle tube. A pair of support plates 7 are fixedly connected to the inner wall of the lower fixing clip 4, and a placement sleeve 8 is fixedly connected to the top of the pair of support plates 7. The heparin cap 1 is placed on the placement sleeve 8. The inner wall size of the placement sleeve 8 is adapted to the outer wall size of the heparin cap 1. A plurality of tube sleeves 9 are fixedly connected to one side of the lower fixing clip 4 and one side of the upper fixing clip 3. The scalp needle 2 is placed on the tube sleeves 9; a limiting component, which is used to prevent the scalp needle 2 from being accidentally touched and pulled out during the use of the scalp needle 2, and the limiting component is connected to the lower fixing clip 4.

[0035] With the upper fixing clip 3 and the lower fixing clip 4 provided, during use, after the indwelling needle is fixed, the scalp needle 2 needs to be connected to the scalp needle 2 fixed on the indwelling needle to pump medicine for the patient. After connecting the scalp needle 2 to the heparin cap 1, the operator can press a pair of pressing plates 10. The pressing plates 10 are provided with fixing grooves, and a plurality of reinforcing rods are fixedly connected in the fixing grooves, which not only strengthens the structural strength of the pressing plates 10 but also facilitates the operator to press the pressing plates 10. When pressing the pressing plates 10, the pressing plates 10 can rotate along the connecting shaft 11, synchronously driving the upper fixing clip 3 to rotate, so that the upper fixing clip 3 and the lower fixing clip 4 are opened. At this time, the operator can place the heparin cap 1 on the placing sleeve 8, so that one side of the heparin cap 1 abuts against one side of the inner wall of the lower fixing clip 4. The indwelling needle tube connected to the heparin cap 1 abuts against the second protective sleeve 6, and the needle handle of the scalp needle 2 can abut against the limiting component, preventing the scalp needle 2 from being accidentally pulled and separated from the heparin cap 1 during use. The connecting tube of the scalp needle 2 can be placed on the tube sleeve 9. At this time, the operator releases the pressing of the pressing plates 10. Under the action of the snap spring 12, the upper fixing clip 3 and the lower fixing clip 4 are closed. Thus, both the heparin cap 1 and the scalp needle 2 are received in the upper fixing clip 3 and the lower fixing clip 4, playing a protective role in the connection part of the heparin cap 1 and the scalp needle 2, so that the heparin cap 1 and the scalp needle 2 will not be separated under external force. Moreover, the upper fixing clip 3 and the lower fixing clip 4 are in a cylindrical shape and will not catch other items on the bed, effectively avoiding accidental scratching. At the same time, the plurality of tube sleeves 9 provided can achieve the effect of protecting the connection parts of multiple scalp needles 2 and the heparin cap 1 when multiple scalp needles 2 are inserted into the heparin cap 1 for use at the same time. The materials of the upper fixing clip 3 and the lower fixing clip 4 are both transparent plastic materials, enabling medical staff to observe the docking situation of the heparin cap 1 and the scalp needle 2 at any time. The utility model has the advantages of simple structure, convenient operation, low production cost and strong practicability.

[0036] As Figures 3 to 5 shown, the limiting component includes a pair of baffles 13 fixedly connected to the inner wall of the lower fixing clip 4. The baffles 13 include a connected guiding plate 14, a rectangular plate 15 and an elastic plate 16. The elastic plate 16 is an elastic arc structure. The guiding plate 14 is inclined towards the bottom of the lower fixing clip 4. The bottom of the elastic plate 16 is fixedly connected to the inner wall of the lower fixing clip 4 through a fixing plate. A protective pad 17 is fixedly connected to one side of the rectangular plate 15. A protective pad 17 is fixedly connected to one side of the baffle 13. A plurality of abutting blocks 18 are fixedly connected to one side of the protective pad 17. The abutting blocks 18 abut against one side of the scalp needle 2. The materials of the protective pad 17 and the abutting blocks 18 are both rubber materials. The abutting blocks 18 are in a triangular structure and are inclined towards the bottom of the protective pad 17.

[0037] Through the provided limit component, during use, when the heparin cap 1 and the scalp needle 2 are received into the upper fixing clip 3 and the lower fixing clip 4, the protective pad 17 provided on one side of the baffle 13 abuts against the needle handle of the scalp needle 2, further limiting the scalp needle 2. It is achieved that during the use of the upper fixing clip 3 and the lower fixing clip 4, under the pulling of external force, the protective pad 17 effectively limits the scalp needle 2, so that the scalp needle 2 will not be separated from the heparin cap 1. Thus, the docking condition at the connection between the scalp needle 2 and the heparin cap 1 is more stable, improving the protection effect of the upper fixing clip 3 and the lower fixing clip 4 on the connection between the heparin cap 1 and the scalp needle 2. The baffle 13 includes a connected guide plate 14, a rectangular plate 15, and an elastic plate 16. Among them, the elastic plate 16 is in an elastic arc structure, and the guide plate 14 is inclined towards the bottom of the lower fixing clip 4. When the heparin cap 1 and the scalp needle 2 are received into the upper fixing clip 3 and the lower fixing clip 4, the needle handle of the scalp needle 2 can move downward along the guidance of the guide plate 14, and under the action of the elastic force of the elastic plate 16, it drives the rectangular plate 15 and the protective pad 17 fixedly connected to one side of the rectangular plate 15 to abut against the needle handle of the scalp needle 2, realizing the limitation of the scalp needle 2. A plurality of abutting blocks 18 inclined towards the bottom of the protective pad 17 are fixedly connected to one side of the provided protective pad 17. The abutting blocks 18 are in a triangular structure and do not hinder the downward movement of the handle of the scalp needle 2. Moreover, both the protective pad 17 and the abutting blocks 18 are made of rubber material with a relatively high softness, which can protect the scalp needle 2 and at the same time increase the friction between the scalp needle 2 and the protective pad 17, making the limiting effect of the protective pad 17 on the scalp needle 2 better.

[0038] The working principle of the technical solution provided by the present utility model is as follows:

[0039] During use, after the indwelling needle is fixed, the scalp needle 2 needs to be connected to the fixed scalp needle 2 on the indwelling needle to pump medicine for the patient. After connecting the scalp needle 2 to the heparin cap 1, the operator can press a pair of pressing plates 10. The pressing plates 10 can rotate along the connecting shaft 11, synchronously driving the upper fixing clip 3 to rotate, so that the upper fixing clip 3 and the lower fixing clip 4 are opened. At this time, the operator can place the heparin cap 1 on the placing sleeve 8, so that one side of the heparin cap 1 abuts against one side of the inner wall of the lower fixing clip 4, and the indwelling needle tube connected to the heparin cap 1 abuts against the second protective sleeve 6. The protective pad 17 provided on one side of the baffle 13 abuts against the needle handle of the scalp needle 2. The baffle 13 includes a connected guide plate 14, a rectangular plate 15 and an elastic plate 16. When the heparin cap 1 and the scalp needle 2 are received into the upper fixing clip 3 and the lower fixing clip 4, the needle handle of the scalp needle 2 can move downward along the guide of the guide plate 14, and drive the rectangular plate 15 and the protective pad 17 fixedly connected to one side of the rectangular plate 15 to abut against the needle handle of the scalp needle 2 under the action of the elastic force of the elastic plate 16, realizing the limitation of the scalp needle 2. The connecting tube of the scalp needle 2 can be placed on the tube sleeve 9. At this time, the operator releases the pressing of the pressing plate 10, and under the action of the snap spring 12, the upper fixing clip 3 and the lower fixing clip 4 are closed, so that the heparin cap 1 and the scalp needle 2 are both received into the upper fixing clip 3 and the lower fixing clip 4, playing a protective role in the connection part of the heparin cap 1 and the scalp needle 2, so that the heparin cap 1 and the scalp needle 2 will not be separated under the action of external force.
