[0023] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0025] Embodiment 1, as Figure 1 As shown, a device for fixing a needle plug of an indwelling needle for intensive blood collection includes a fixing plate 1. The fixing plate 1 is a basic component for fixing and is responsible for providing structural support. The fixing plate 1 can be used to firmly fix the needle plug of the indwelling needle on the subject.

[0026] The fixing plate 1 is provided with strap holes 2 at the four corners, and straps 3 are passed through the strap holes 2. The strap holes 2 are used to pass the straps 3, and the straps 3 are used to fix the fixing plate 1 on the subject. The straps can be adjusted as needed and are generally fixed on the arm to ensure the stability of the indwelling needle plug. The use of the straps 3 can effectively avoid the problems of adhesive tape adhesion and allergies.

[0027] The front end of the fixed plate 1 is set as a fixed platform 4, and the middle and rear ends of the fixed plate 1 are set as a recessed platform 5. The recessed platform 5 has a reserved position to facilitate the fixing of the syringe 9, ensuring that the indwelling needle at the top of the syringe 9 can be fixed on the fixed platform 4, so as to achieve the smooth progress of the blood collection operation. A fixed seat 6 is set on the recessed platform 5, and the height of the fixed seat 6 is slightly higher than the recessed platform 5, which is convenient for fixing. A fixed ring 7 is set on the top of the fixed seat 6, and the syringe 9 is fixed on the fixed ring 7. The barrel wall of the syringe 9 is fixed by the fixed ring 7. The fixed single seat 8 is provided with a fixed protrusion 10 on the fixed platform 4, which is lifted by the fixed protrusion 10. A fixed sleeve 11 is set on the top of the fixed protrusion 10, and the fixed sleeve 11 is convenient for passing the needle of the syringe 9 through the needle plug to fix it.

[0028] The following is a detailed description of the design of the above key components:

[0029] The depth of the recessed platform 5 is 3 mm. The recessed platform 5 is a part of the fixing plate 1. By setting a recessed platform 5 of a certain depth, it can be ensured that the syringe 9 is firmly placed, providing better support and fixation.

[0030] The fixing seat 6 is located at the center of the recessed platform 5, so that the syringe 9 and the indwelling needle are fixed at the center of the platform to maintain stability.

[0031] A fixed single seat 8 is arranged at the rear side of the fixed seat 6, and a fixed ring 7 is arranged on the fixed single seat 8. The fixed single seat 8 is a supplementary component of the fixed seat 6. By arranging the fixed ring 7 on the fixed single seat 8, the push handle of the syringe 9 can be placed in the gap formed by the fixed ring 7 on the fixed single seat 8 and the rear end of the fixed seat 6, so as to facilitate fixation.

[0032] The number of the fixing rings 7 is several, and the fixing rings 7 are arranged at a fixed distance. A plurality of fixing rings 7 are arranged, and a certain distance is maintained between them, providing multiple fixing points, increasing stability, and preventing the syringe 9 from shaking or loosening.

[0033] The top surface of the fixing platform 4 is covered with a Velcro A surface, and the bottom of the fixing protrusion 10 is provided with a Velcro B surface. Through the structural design of the Velcro, the fixing protrusion 10 can be conveniently and quickly removed and fixed on the surface of the fixing platform 4, so that the fixing protrusion 10 is conveniently fixed in a suitable position.

[0034] There are two straps 3, one each provided at the front and rear of the fixing plate 1. The straps 3 are Velcro structures, which can provide a firm fixing effect and are easy to adjust to meet the needs of different subjects.

[0035] The fixing ring 7 is a ring-shaped structure with an open top, which is convenient for placing and fixing the syringe 9, and can effectively prevent the syringe 9 from slipping or moving, thereby ensuring the stability and accuracy of the blood collection operation.

[0036] Embodiment 2, as shown in Embodiment 1, is a device for fixing the needle plug of an indwelling needle for intensive blood collection. When the indwelling needle is used for blood collection, the median cubital vein is usually selected. After the indwelling needle is used for blood collection, the fixing sleeve 11 can be firstly put on the needle plug of the indwelling needle. Before the formal intensive blood collection, the fixing plate 1 is fixed to the forearm with the strap hole 2 using the strap 3. The front fixing platform 4 is close to the cubital fossa, 3-5 cm away from the puncture point.

[0037] After a round of blood collection is completed, the blood collection needle is disconnected from the blood collection conversion joint, and the empty needle syringe 9 with the tube sealing liquid is connected to seal the tube. Then, the needle plug and syringe 9 are fixed in the device: the syringe 9 is located on the recessed platform 5, and the fixing protrusion 10 is connected to the fixing platform 4 to prevent the needle plug from moving and disconnecting from the syringe 9 to cause contamination; the syringe 9 is stuck in the fixing ring 7, wherein the push handle of the syringe 9 is stuck in the gap formed by the fixing ring 7 on the fixed single seat 8 and the fixing ring 7 at the rear end of the fixing seat 6 to prevent the syringe 9 from moving back and forth and falling off.

[0038] Before the next round of blood collection, the medical staff only needs to lift the needle plug and the syringe 9 to complete the separation of the device and start the blood collection operation. After the intensive blood collection is completed, the medical staff removes the blood collection needle, or separates the blood collection needle from the syringe 9, installs the heparin cap to fix it, loosens the bandage 3, and removes the fixing plate 1.

[0039] The contents not described in detail in this specification belong to the prior art known to professionals in this field.

[0040] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
