[0002] The purpose of the sealing plug in the indwelling needle used in the market is only to block it. When the puncture needle is pulled out of the indwelling needle, blood will not flow out from here, and it has no other purpose.
The instructions for the use of the indwelling needle all introduce that the indwelling needle can be used to draw blood for testing, but in clinical practice, no one uses the indwelling needle to draw blood, because if the indwelling needle is used to draw blood, the blood in the indwelling needle must first be removed. The liquid is drawn out with a syringe, and a part of the blood must be drawn out and discarded at the same time to ensure the accuracy of the blood test in the indwelling needle at this time. For the required amount of blood, remove the syringe from the indwelling needle and put it aside for later use; then use a syringe filled with normal saline to flush the catheter of the indwelling needle, and discard the syringe after flushing; after the above operations, save The blood in the syringe is repacked into the blood collection tube, and the blood draw is completed at this time
This operation is not only cumbersome for nurses, but part of the blood is discarded by the patient, and there is also a link where the blood passes through the air, which increases the chance of infection, so it is not popular

Embodiment 1
[0024] Such as figure 1 As shown, the indwelling needle holder capable of drawing blood is composed of a puncture needle holder 1, a compression cover 2, an elastic sealing plug 3, an indwelling needle holder 4, a catheter 5, a stop clamp 6, and an infusion interface 7. Such as Figure 8 As shown, the puncture needle hub 1 is installed on the outer port of the indwelling needle hub 4 . Such as Figure 9 , Figure 10 As shown, in the prior art, the puncture needle holder is installed in the inner port of the indwelling needle holder.
[0025] Such as Figure 4 -- Figure 7 As shown, the elastic sealing plug 3 can be made into a cylindrical structure. The upper end surface of the elastic sealing plug 3 is flat or the central part protrudes upwards. When the upper end surface of the elastic sealing plug 3 is a flat structure, it is not necessary to set the compression cover 2 . When the central part of the upper end surface protrudes upwards, it is necessary to set a compre...

The invention relates to a remaining needle base capable of exsanguinating, which consists of a puncture needle base 1, a tightening cap 2, an elastic sealing plug 3, the remaining needle base 4, a guide tube 5, a closing clip 6 and a transfusion interface 7, wherein the elastic sealing plug 3 can be transparent and also can be non-transparent, and the transparent elastic sealing plug 3 is beneficial to observation. The remaining needle base has the advantage that the elastic sealing plug 3 can be repeatedly punctured, thus not only increasing a channel for transfusion by using a remaining needle, most importantly leading exsanguinating by using the remaining needle to become operable, and reducing tedious procedures for searching blood vessels when exsanguinating every time by medical personnel; and simultaneously, the blood vessels of patients do not need to be punctured for multiple times, thus alleviating the pain of the patients.
Description
technical field [0001] The invention relates to an indwelling needle holder capable of drawing blood, and belongs to the technical field of medical infusion devices. Background technique [0002] The purpose of the sealing plug in the indwelling needle used in the market is only to block, and when the puncture needle is pulled out from the indwelling needle, blood is not allowed to flow out from here, and there is no other purpose. The instructions for the use of the indwelling needle all introduce that the indwelling needle can be used to draw blood for testing, but in clinical practice, no one uses the indwelling needle to draw blood, because if the indwelling needle is used to draw blood, the blood in the indwelling needle must first be removed. The liquid is drawn out with a syringe, and a part of the blood must be drawn out and discarded at the same time to ensure the accuracy of the blood test in the indwelling needle at this time.
