Based on the embodiments in the utility model, all the other embodiments obtained by the ordinary skilled in the art without creative labor belong to the protection scope of the utility model.
[0024] Embodiment, please refer to Figures 1-5The embodiment provides a blood taking needle, which comprises a needle seat 1 and a needle tube 2, the needle tube is fixed to one end of the needle seat, the other end of the needle seat is provided with an interface 1-2 in communication with the inside of the needle tube, which is used for connecting a blood taking device such as a vacuum blood taking tube, one end of the needle seat close to the interface is provided with a folding mechanism 3 and a substrate 4, one side of the substrate is connected with the folding mechanism, and the other side of the substrate is provided with medicine for hemostasis and / or disinfection. In the embodiment, the folding mechanism comprises a connecting body 3-1 and a connecting seat 3-2, the connecting body is fixed to the needle seat or the interface; the connecting seat is connected with the connecting body, and a folding part is arranged at the connecting position, wherein the connecting seat and the connecting body can be made of metal or high polymer material, the connecting seat and the connecting body are preferably integrally arranged, and the folding part is an opening 3-3, of course, the connecting seat and the connecting body can also be connected in other manners, such as hinged, as long as the folding function of the connecting seat and the connecting body can be realized; the connecting seat is provided with a groove 3-22 for covering the needle tube, and the connecting seat is provided with an L-shaped insertion piece 3-21 on one side or both sides of the groove, one side of the substrate not provided with medicine is provided with an insertion part matched with the insertion piece, one end of the L-shaped insertion piece is connected with the connecting seat, and the other end is inserted into the insertion part, in the embodiment, the insertion part is a strip-shaped protrusion 4-1 arranged on the substrate, the strip-shaped protrusion is provided with an insertion hole, and the insertion piece is inserted into the insertion hole.
[0025] In the above embodiment, the opening is arranged to face away from the substrate, so that when being manufactured, the opening only needs to be arranged as a strip-shaped opening, so that when being folded, the connecting seat can only be rotated in one direction, and when being rotated in the opposite direction, the strip-shaped opening is closed and cannot be rotated, thereby preventing the connecting seat from being rotated in the opposite direction.
[0026] As an implementation manner, one side of the substrate provided with medicine is provided with glue at the edge position; one side of the substrate provided with medicine is provided with release paper, the release paper can keep the medicine clean before being used, the release paper is removed when being used, the connecting seat is folded to make the substrate adhere to the puncture position, so that subsequent operation of people is facilitated, in the embodiment, the glue preferably uses anti-allergic biological glue, the anti-allergic biological glue can be firmly adhered to the surface of the blood taking wound, accelerates hemostasis, and effectively avoids the continuous pressing operation required in the conventional disinfection cotton ball hemostasis step; the medicine can use benzalkonium chloride or Yunnan white drug, accelerates blood coagulation, and effectively avoids the continuous pressing operation required in the conventional disinfection cotton ball hemostasis step.
[0027] In the embodiment, the substrate can be a cotton or non-woven fabric sheet.
[0028] In order to facilitate operation, the needle seat is provided with side wings 1-1 on both sides to facilitate operation of people.
[0029] After the blood sampling operation is completed, the medical staff folds the connecting seat, the folded base plate is attached to the puncture site, and then the base plate is pressed to pull out the blood sampling needle at the puncture site, so that the medical staff does not need to use tweezers to clamp the sterilized cotton, and then press the sterilized cotton on the puncture site. The operation is relatively simple. In addition, after the needle tube of the blood sampling needle is separated from the puncture part, it can enter the groove under the folding action to prevent the needle tube from being exposed and injuring the medical staff in the subsequent scrap processing process.
[0030] In actual use, the medical staff can operate with one hand: one or more of the four fingers other than the thumb are used to block the needle seat on the back of the gap, the thumb is used to press the connecting seat on one side of the gap to fold it, the base plate is attached to the puncture site after folding, and the index finger is pressed. The base plate, two fingers (such as the middle finger and the thumb) among the other four fingers pinch the side wing to pull out the blood sampling needle.
