Description

Technical Field

[0001] The invention relates to the field of medical instruments, and in particular to a pediatric special scalp needle which is easy to seal and remove the needle. Background Art

[0002] Scalp needles or intravenous infusion needles are a type of needle commonly used in disease treatment. Usually, a scalp needle consists of a needle, a needle handle and an infusion tube. The needle, needle handle and infusion tube are connected in sequence. During infusion, the needle is inserted into the patient's vein, and the needle handle remains outside the body.

[0003] In clinical medicine, the use of existing scalp needles has the following problems. The main problem is that after the infusion is completed, the nurse needs to pull out the patient's scalp needle. However, when pulling out the needle, a liquid flow regulator is provided on the existing infusion tube. After the infusion is completed, the liquid flow regulator is closed to stop the flow of liquid in the infusion tube. However, because the medical staff needs to squeeze the liquid flow regulator hard, there is insufficient residual force at the position of the thumb on the inside of the palm, resulting in the inability to pull out the scalp needle, which will cause harm to the patient. Secondly, the medical staff needs to pull out the patient's scalp needle, but when pulling out the needle, the blood in the needle often flows out, resulting in blood contamination. Thirdly, when pulling out the scalp needle, due to the limited length of the extension tube, if it is not pulled out carefully, the catheter assembly will be pulled out of the patient's body. In order to avoid the above accidents, medical staff are cautious when operating. Sometimes the stop clamp is not pulled out long enough, and it is still impossible to completely ensure that the blood in the catheter is driven out. Therefore, this operation method invisibly increases the workload and psychological burden of medical staff.

[0004] Therefore, the production of a pediatric scalp needle with a simple structure, which is convenient for medical staff to remove scalp needles with less effort, reduces the workload and psychological burden of medical staff, and ensures the safety of patients and medical staff. The needle is easy to seal and remove, has broad market prospects. Summary of the invention

The diameters are consistent, the pull ring 7 adopts a hollow pull ring structure, the pull ring sleeve 6 and the pull ring 7 are an integrated structure, and the present invention can quickly pull the scalp needle 2 out of the patient's vein by setting and using the pull ring sleeve 6 and the pull ring 7, thereby reducing the patient's pain, and at the same time saving the medical staff, reducing the medical staff's work pressure and psychological burden; a buckle is provided on the top surface of the liquid conduit 5, and the buckle adopts a hollow inverted truncated cone structure, the liquid conduit 5 and the buckle are an integrated structure, the top of the liquid conduit 5 is sleeved on the liquid outlet at the bottom of the liquid flow regulator 1 through the buckle, the bottom surface of the liquid conduit 5 is provided on the top surface of the needle handle 4, and the liquid conduit 5 and the needle handle 4 are an integrated structure; the liquid outlet of the liquid conduit 5 is connected to the top of the scalp needle 2 through the isolation plug 3.

[0018] A pediatric scalp needle that is easy to seal and remove, comprising a liquid flow regulator 1, a scalp needle 2 located below the liquid flow regulator 1, a liquid delivery tube 5 is arranged between the liquid flow regulator 1 and the scalp needle 2, an isolation plug 3 is arranged on the top surface of the scalp needle 2, an annular needle handle sleeve 8 is arranged above the isolation plug 3, one end of the liquid delivery tube 5 is sleeved on the liquid outlet at the bottom of the liquid flow regulator 1, and the other end of the liquid delivery tube 5 is sleeved inside the isolation plug 3 through the annular needle handle sleeve 8, and a pull ring 7 is arranged on the side wall of the annular needle handle sleeve 8; the annular needle handle sleeve 8 adopts a hollow cylindrical columnar structure, and the liquid delivery tube 5 is arranged between the liquid flow regulator 1 and the scalp needle 2. The tube 5 is sleeved inside the annular needle handle sleeve 8, the outer diameter of the liquid delivery tube 5 is consistent with the diameter inside the annular needle handle sleeve 8, the pull ring 7 and the annular needle handle sleeve 8 are an integrated structure, and the present invention can quickly pull out the scalp needle 2 from the patient's vein by setting and using the pull ring 7 and the annular needle handle sleeve 8, thereby reducing the patient's pain, and at the same time saving the medical staff effort, reducing the medical staff's work pressure and psychological burden; the liquid delivery tube 5 is sleeved inside the isolation plug 3 through the annular needle handle sleeve 8, the liquid outlet of the liquid delivery tube 5 is connected to the scalp needle 2, and the diameter of the annular needle handle sleeve 8 is consistent with the diameter of the isolation plug 3.

[0019] The method of using this product is as follows: Example 1: Figure 1 As shown, the pull ring sleeve 6 is put on the liquid delivery tube 5, and the medical staff starts to perform routine operations to insert it into the patient's vein. When the liquid in the liquid flow regulator 1 is about to be squeezed out, the medical staff hooks the pull ring 7 set on the side wall of the pull ring sleeve 6 with the little finger of the hand holding the liquid flow regulator 1, and presses the scalp needle 2 with the other hand. According to the penetration force, the liquid in the liquid flow regulator 1 is squeezed out, and the needle set in the scalp needle 2 is taken out by pulling the pull ring 7. In this way, the medical staff will not be able to pull out the needle due to insufficient residual force caused by squeezing when pulling out the needle.

[0020] Embodiment 2: Figure 2 As shown, the pull ring 7 is set on the side wall of the needle handle 4, and the medical staff starts to perform routine operations to insert it into the patient's vein. When the liquid in the liquid flow regulator 1 is about to be squeezed out, the medical staff hooks the pull ring 7 set on the side wall of the needle handle 4 with the little finger of the hand holding the liquid flow regulator 1, and presses the scalp needle 2 with the other hand. According to the penetration force, the liquid in the liquid flow regulator 1 is squeezed out, and the needle set in the scalp needle 2 is taken out by pulling the pull ring 7. This can reduce the situation where the medical staff cannot pull out the needle due to insufficient residual force caused by squeezing when pulling out the needle.

[0021] Embodiment 3: Figure 3 As shown, an annular needle handle sleeve 8 is arranged on the top of the isolation plug 3, so that the annular needle handle sleeve 8 is connected to the needle on the scalp needle 2, and a pull ring 7 is arranged on the side wall of the annular needle handle sleeve 8. The medical staff starts to perform routine operations to insert it into the patient's vein. When the liquid in the liquid flow regulator 1 is about to be squeezed out, the medical staff hooks the pull ring 7 arranged on the side wall of the annular needle handle sleeve 8 with the little finger of the hand holding the liquid flow regulator 1, and presses the scalp needle 2 with the other hand. According to the penetration force, the liquid in the liquid flow regulator 1 is squeezed out, and the needle arranged in the scalp needle 2 is taken out by pulling the pull ring 7, so that the medical staff can reduce the situation that the residual force is insufficient due to squeezing when pulling out the needle, and the needle cannot be pulled out.

[0022] The present invention has a simple structure, is convenient for medical staff to remove scalp needles with little effort, reduces the workload and psychological burden of medical staff, ensures the safety of patients and medical staff, and is easy to seal and remove the needle.
