[0009] Furthermore, the puncture needle also includes a check valve arranged at the other end of the connecting tube to prevent blood from flowing back.

[0010] Furthermore, the mounting mechanism includes an elastic clamp arranged on the side of the fixer body for fixing the check valve.

[0011] Furthermore, the check valve comprises a check valve body with a hollow structure, a mounting portion embedded in the rear end of the check valve body and connected to the infusion tube, and a check valve member arranged inside the check valve body, wherein the mounting portion is provided with a liquid inlet hole.

[0012] Furthermore, the anti-return component includes two limit ridges arranged on the inner wall of the anti-return device body in an upper and lower direction and a anti-return ball arranged between the limit ridges and the mounting portion, and a liquid flow channel is formed between the two adjacent limit ridges.

[0013] Furthermore, the distance between the two limit ridges is smaller than the diameter of the check ball; and the diameter of the check ball is larger than the diameter of the liquid inlet hole.

[0014] Furthermore, the fixer also includes an adhesive portion arranged at the bottom of the fixer body.

[0015] It can be seen from the above description of the utility model that, compared with the prior art, the utility model has the following beneficial effects: the present application defines the specific structure of the scalp needle for preventing needlestick injuries. When in use, the medical staff attaches the fixator to the patient's head, and then tilts the puncture needle downward into the accommodating cavity, so that the puncture needle head is inserted into the accommodating cavity for puncture, which can reduce the risk of needlestick injuries to the medical staff during intravenous infusion, and when the needle is removed, the puncture needle head is located in the accommodating cavity, which can avoid liquid splashing; by providing a magnifying glass on the fixator body opposite to the front end of the puncture needle head, the medical staff can accurately insert the needle into the patient's blood vessel, thereby improving the success rate of the needle insertion;

[0016] The fixing needle wing which is arranged on the connecting tube and can be supported on the top of the fixing body allows the medical staff to hold the puncture needle comfortably when puncturing or removing the needle, thus preventing the puncture needle from slipping from the hand and causing needle puncture injury;

[0017] By setting a check valve at the other end of the connecting tube to prevent blood backflow, it can be used to prevent blood from entering the infusion tube, thereby improving the safety of scalp acupuncture use. BRIEF DESCRIPTION OF THE DRAWINGS

At this time, the liquid enters the connecting tube 11 through the liquid flow channel 147; when blood refluxes, blood enters the anti-return device body 141, and the anti-return ball 146 is squeezed by the blood to block the liquid inlet hole 144 to prevent blood from entering the infusion tube; further, the distance between the two limiting eaves 145 is smaller than the diameter of the anti-return ball 146; the diameter of the anti-return ball 146 is larger than the diameter of the liquid inlet hole 144.

[0027] The fixator 2 is made of a transparent plastic material and can be adhered to the patient's head. It includes a fixator body 21, a receiving cavity 22 arranged in the fixator body 21 for receiving the puncture needle 13, a magnifying glass 23 arranged on the fixator body 21 opposite to the front end of the puncture needle 13, and an adhesive portion 24 arranged at the bottom of the fixator body 21; wherein the mounting mechanism 12 includes an elastic clamp 121 arranged on the side of the fixator body 21 for fixing the check valve 14, a fixing plate 122 arranged in the receiving cavity 22 and inclined along the entry direction of the puncture needle 13, and the connecting tube 11 is detachably arranged on the fixing plate 122, and a fixing groove 123 for the connecting tube 11 to be embedded is formed on the fixing plate 122; specifically, when in use, the medical staff sticks the fixator body 21 to the patient's head through the adhesive portion 24, and then tilts the puncture needle 1 downward into the receiving cavity 22, so that the puncture needle 13 is inserted in the receiving cavity, which can reduce the risk of needle stick injuries to the medical staff during intravenous infusion. Risk, and, when the needle is pulled out, the puncture needle 13 is located in the accommodating chamber 22, which can avoid liquid splashing; further, the puncture needle 1 also includes a fixed needle wing 15 arranged on the connecting tube 11 and can be supported on the top of the fixture body 21, and the fixing plate 122 can be arranged opposite to the fixed needle wing 15 up and down; when puncturing or pulling out the needle, the medical staff can hold the puncture needle 1 comfortably through the fixed needle wing 15 to prevent the puncture needle 1 from slipping from the hand and causing needle puncture injuries; at the same time, the medical staff can use disposable tape to fix the fixed needle wing 15 on the top of the fixture body 21; further, the accommodating chamber 22 includes a mounting section 25 extending inward from the side of the fixture body 21 for installing the fixing plate 122 and an extension section 26 connected to the mounting section 25 for accommodating the puncture needle 13, and a magnifying glass 23 is arranged on the fixture body 21 opposite to the extension section 26. The magnifying glass 23 magnifies the patient's blood vessel position, so that the medical staff can accurately insert the patient's blood vessel and improve the success rate of acupuncture.

[0028] In summary, with the help of the above-mentioned technical scheme of the utility model, the cooperation between the fixator 2 that can be adhered to the patient's head and the puncture needle 1 that can be detachably mounted on the fixator 2 can reduce the risk of needle stick injuries to medical staff during intravenous infusion, and when the needle is pulled out, the puncture needle head 13 is located in the accommodating cavity 22, which can avoid liquid splashing; in addition, by magnifying the patient's blood vessel position through the magnifying glass 23 arranged on the fixator body 21 opposite to the extension section 26, the medical staff can accurately insert the blood vessel of the patient, thereby improving the success rate of acupuncture; in addition, by the check valve 14 arranged at the other end of the connecting tube 11 to prevent blood backflow, blood can be prevented from entering the infusion tube, thereby improving the safety of scalp needle use; in addition, by the fixed needle wing 15 arranged on the connecting tube 11 and supported on the top of the fixator body 21, the medical staff can comfortably hold the puncture needle 1 when puncturing or pulling out the needle, thereby preventing the puncture needle 1 from slipping from the hand and causing needle stick injuries.
