Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and in particular relates to an integrated needle for blood sampling, enhanced CT and magnetic resonance injection. Background Art

[0002] An indwelling needle is a needle for venous puncture, which is composed of a stainless steel blood collection needle, a soft hose and a plastic needle holder. During puncture, the hose and the blood collection needle are inserted into the blood vessel together. When the catheter is sent into the blood vessel, the core is pulled out, and only the soft catheter is left in the blood vessel for infusion treatment.

[0003] The current indwelling needle structure is Y-shaped, including a steel needle, a handle, a rubber plug and a hose. In addition, it also includes a Y-shaped connector connected to the hose, and the Y-shaped connector is provided with a connector protection cap and a heparin cap. Therefore, the overall structure of the indwelling needle is relatively complex, and the medical staff are required to have high operational standards. At the same time, the patient is also required to take care of it carefully. Once the tube is not sealed in time or is not standardized, and the needle slips off, the dressing is damaged, etc., it is easy to cause local exudation. If it is not handled in time, it may affect the treatment effect or cause adverse conditions such as bacterial infection. In this regard, it is also necessary to provide a more reasonable technical solution to solve the current technical problems. Utility Model Content

[0004] The utility model aims to provide an integrated needle for blood sampling, enhanced CT and magnetic resonance injection, so as to solve the problem that the current indwelling needle has a complex structure and is difficult to care for.

[0005] In order to achieve the above-mentioned purpose, the utility model provides an integrated needle for blood sampling, enhanced CT and magnetic resonance injection, comprising a blood collection needle and a fixed tube, wherein the blood collection needle is used to connect a blood collection tube; wherein the fixed tube comprises a soft tube and an outer tube, wherein the outer tube is formed as a hard tube and a handle for holding is formed on the outer periphery of the outer tube, wherein the handle has a basic area for fingers to grasp; one end of the outer tube is coaxially connected to the soft tube, and the other end is connected to a screw plug;

[0006] A flexible sealing film is provided in the middle area of ​​the inner wall of the spiral plug. When the blood collection needle is inserted into the outer tube, the sealing film inside the spiral plug is flexibly deformed and pressed against the outer wall of the blood collection needle, so that the blood collection needle is sealedly inserted in the outer tube; when the blood collection needle is pulled out of the outer tube, the sealing film is flexibly deformed and seals the channel of the outer tube.

[0007] Optionally, the outer tube is threadedly connected to the screw plug.

[0008] The method of using the integrated needle for blood sampling, enhanced CT and MRI injection is as follows: the medical staff inserts the hose and the blood collection needle into the blood vessel together, and after completing the puncture and blood collection, the blood collection needle is pulled out, leaving the hose in the blood vessel. When the blood collection needle is pulled out, based on the characteristics of the sealing film, the sealing film can be restored to its original state, so that the spiral plug is sealed. After the blood collection is completed, the blood collection needle is pulled out, and the outer tube is used to inject the anticoagulant drug heparin to prevent the blood from clotting in the tube. At a fixed time, CT enhanced imaging solution can also be injected to provide patients with clear imaging diagnosis.

[0009] The soft tube can relieve the patient's pain and fear of puncture, and the soft needle has good mobility. The patient's hands are less restricted during infusion, and the soft needle is not easy to puncture the blood vessels, so the safety is relatively high. The integrated needle is convenient for continued injection and is in a fixed position, which can reduce nursing work. When infusion treatment is needed, it can be directly connected to the exposed interface. This helps to reduce damage to blood vessels, reduce the pain of patients and the workload of medical staff.

[0010] Through the above technical solution, the characteristics of the sealing film in the spiral plug can realize the fastening and sealing of the blood collection needle and the automatic sealing of the integrated needle in the later stage. During the puncture process, the blood collection needle is inserted into the hose, and the sealing film plays a role of fastening and sealing, so that medical staff can safely insert the hose and the blood collection needle into the blood vessel together to complete the blood collection operation. The integrated needle for blood collection, enhanced CT and magnetic resonance injection combines the functions of blood collection and injection, which can not only reduce the pain and fear of patients, but also improve the work efficiency of medical staff. In addition, by optimizing and improving the structure of the integrated needle, its structure becomes simple and convenient for patients to move.
