Description

Technical Field

[0001] The utility model relates to the field of medical instruments, and more specifically, to a disposable injection needle with double wings. Background Art

[0002] A venous blood collection needle is a blood collection needle used to collect blood samples during medical examinations. The top of the blood collection needle is used to puncture the blood vessel, and the transparent hose at the tail end is connected to the tail needle. The tail needle is wrapped with a rubber hose and covered with a needle cap. It is used to pierce the vacuum blood collection tube. When collecting blood, the negative pressure in the test tube draws blood into the tube.

[0003] When the existing injection needles are used in the later stage, when puncturing patients with small blood vessels such as infants and young children, the puncture needles may swing left and right or slip out of the blood vessels after entering the blood vessels, which may cause unnecessary trouble to the patients and may also affect the accuracy of blood collection. At the same time, some needles fail to fully consider safety factors during the design and manufacturing process. For example, the design of the needle safety cap is not tight enough or is easy to fall off, which may cause the needle to be contaminated or damaged during storage, transportation or use, increasing the risk of cross infection;

[0004] Therefore, a disposable injection needle with double wings is proposed to address the above problems. Utility Model Content

[0024] As attached Figure 1-4 A disposable injection needle with double wings shown in the figure comprises a puncture needle 1, an auxiliary mechanism 2 of the injection needle is installed on the outside of the puncture needle 1, and the auxiliary mechanism 2 comprises a needle seat 3, a needle handle 4, a needle wing 5, a fixing seat 6, a protective sleeve 7, a protective seat 8, a first through groove 9, and a second through groove 10; the needle seat 3 is fixedly installed on the bottom of the puncture needle 1, the needle handle 4 is fixedly installed on the bottom of the needle seat 3, the needle wing 5 is fixedly installed on the outside of the needle handle 4, the fixing seat 6 is fixedly installed on the bottom of the needle handle 4, the protective sleeve 7 is nested and installed on the outside of the puncture needle 1, the protective seat 8 is fixedly installed on the bottom of the protective sleeve 7, a first through groove 9 is penetrated on one side of the inner side of the protective sleeve 7, and a second through groove 10 is penetrated on the inner side of the protective seat 8.

[0025] Among them: ensure that the protective sleeve 7 is correctly nested on the outside of the puncture needle 1, and the protective seat 8 is stably connected to the fixed seat 6. Before preparation, the protective sleeve 7 is installed on the outside of the puncture needle 1, and the first through groove 9 is installed on the outside of the needle wing 5, and the protective seat 8 is installed on the top of the fixed seat 6. When puncturing, just take out the protective sleeve 7, and use the needle wing 5 with anti-slip grooves 11. The design of the needle wing 5 enables the doctor or nurse to hold the needle handle 4 more stably when inserting the needle, improves the accuracy and safety of the operation, and accurately inserts the puncture needle 1 into the patient's body. After the puncture is successful, the syringe can be connected through the needle seat 3 to inject the drug. After the injection is completed, gently pull out the puncture needle 1 and ensure that the protective sleeve 7 is re-nested on the puncture needle 1 to prevent accidental injury and improve the safety of use.

[0026] Embodiment 2

[0027] Based on the first embodiment, the solution in the first embodiment is further detailed in combination with the following specific working method, as described below:

[0028] like Figure 4 As shown, as a preferred embodiment; the outside of the needle wing 5 is fixedly installed with an anti-slip pattern 11. Furthermore, the anti-slip pattern 11 can increase the friction when the doctor or nurse holds the needle wing 5, making the grip more stable and less likely to cause the needle to slip or deviate from the predetermined position due to sweating of the hands or slight shaking during operation, thereby ensuring that the drug is accurately injected into the target position, thereby improving the treatment effect.

[0029] The working process of the utility model is as follows:

[0030] When using this disposable injection needle with double wings, first ensure that the protective sleeve 7 is correctly nested on the outside of the puncture needle 1, and the protective seat 8 is stably connected to the fixing seat 6. Before preparation, the protective sleeve 7 is installed on the outside of the puncture needle 1, and the first through groove 9 is installed on the outside of the needle wing 5, and the protective seat 8 is installed on the top of the fixing seat 6. When puncturing, the protective sleeve 7 can be taken out, and the needle wing 5 with anti-slip grooves 11 is used. The design of the needle wing 5 enables the doctor or nurse to hold the needle handle 4 more stably when inserting the needle, improves the accuracy and safety of the operation, and accurately inserts the puncture needle 1 into In the patient's body, after the puncture is successful, the syringe can be connected through the needle seat 3 to perform drug injection. After the injection is completed, the puncture needle 1 is gently pulled out, and the protective cover 7 is ensured to be re-nested on the puncture needle 1 to prevent accidental injury and improve the safety of use. The design of the anti-slip pattern 11 can increase the friction of the doctor or nurse when holding the needle wing 5, making the grip more stable, and it is not easy to cause the needle to slip or deviate from the predetermined position due to sweating of the hands or slight shaking during operation, thereby ensuring that the drug is accurately injected into the target position, thereby improving the treatment effect. This is the working process and working principle of the device.
