DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] For examples, see Figure 1-Figure 5The present embodiment provides a blood collection needle, comprising a needle seat 1 and a needle tube 2, wherein the needle tube is fixed to one end of the needle seat, and the other end of the needle seat is provided with an interface 1-2 connected to the inside of the needle tube, for connecting a blood drawing device such as a vacuum blood collection tube, and a folding mechanism 3 and a substrate 4 are provided at one end of the needle seat close to the interface, one side of the substrate is connected to the folding mechanism, and the other side is provided with a drug for hemostasis and / or disinfection. In this embodiment, the folding mechanism includes a connector 3-1 and a connector seat 3-2, and the connector is fixed on the needle seat or the interface; the connector seat is connected to the connector, and a folding portion is provided at the connection position, wherein the connector seat and the connector can be made of metal or polymer material, and the connector seat and the connector are preferably integrally provided, and the folding portion is a notch 3-3. Of course, the connector seat and the connector can also be connected in other ways, such as hinged, as long as the function of the connector seat and the connector being able to fold can be achieved; a groove 3-22 for covering the needle tube is provided on the connector seat, and an L-shaped insert 3-21 is provided on one side or both sides of the groove on the base, and a plug-in portion cooperating with the insert is provided on the side of the base sheet where no medicine is provided, and one end of the L-shaped insert is connected to the base, and the other end is inserted into the plug-in portion. In this embodiment, the plug-in portion is a strip protrusion 4-1 provided on the base sheet, and a plug hole is provided on the strip protrusion, and the insert sheet is inserted into the plug hole.

[0017] In the above embodiment, the notch is arranged with its back to the substrate, so that during manufacturing, it is only necessary to set the notch as a strip-shaped notch, so that the connecting seat can only be rotated in one direction when folded, and the strip-shaped notch is closed when rotated in the opposite direction and cannot be rotated, thereby preventing the connecting seat from rotating in the opposite direction.

[0018] As an implementation mode, one side of the substrate provided with the medicine is provided with glue at the edge position; one side of the substrate provided with the medicine is provided with release paper, and the release paper can keep the medicine clean before use. When in use, the release paper is removed, and the folded connecting seat makes the substrate stick to the puncture part to facilitate people's subsequent operation. In this embodiment, the glue preferably uses anti-allergic biological glue, which can be firmly adhered to the surface of the blood collection wound, accelerate hemostasis, and effectively avoid the continuous pressing operation required for the conventional disinfection cotton ball hemostasis step; the medicine can use benzalkonium chloride or Yunnan Baiyao, etc., to accelerate blood coagulation and effectively avoid the continuous pressing operation required for the conventional disinfection cotton ball hemostasis step.

[0019] In this embodiment, the substrate may be a cotton or non-woven fabric sheet.

[0020] For the convenience of operation, side wings 1 - 1 are provided on both sides of the needle seat to facilitate operation.

[0021] After the blood collection operation is completed, the medical staff folds the connecting seat of the above-mentioned blood collection needle, and the folded base sheet fits the puncture site, and then presses the base sheet to pull out the blood collection needle at the puncture site. In this way, the medical staff does not need to use tweezers to clamp the disinfectant cotton and then press the disinfectant cotton on the puncture site. The operation is relatively simple. In addition, after the needle tube of the blood collection needle is separated from the puncture part, it can enter the groove under the action of folding, so as to prevent the needle tube from being exposed and accidentally injuring medical staff during the subsequent scrapping process.

[0022] In actual use, medical personnel can operate it with one hand: use one or more of the four fingers other than the thumb to block the needle seat on the back of the notch, use the thumb to squeeze the connecting seat on one side of the notch to fold it, and after folding, the base sheet fits the puncture site, press the base sheet with a single finger (such as the index finger), and pinch the side wings with two of the other four fingers (such as the middle finger and thumb) to pull out the blood collection needle.

[0023] It should be noted that in the above embodiment, the folding mechanism may also use other existing structures, as long as it can achieve the following function: when in use, the folding mechanism can be folded relative to the needle seat, the base sheet is pressed against the puncture site, and the drug is in contact with the puncture site. No specific limitation is made here.
