[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. After inserting the needle, the medical non-woven fabric can be pressed down, thereby pressing the medical double-sided adhesive tape I and bonding it on the human body, which, compared with directly bonding the catheter and the human body with the medical double-sided adhesive tape I, can ensure that the catheter is not squeezed under the premise of stable bonding and ensure the flow of blood in the catheter, and the overall structure is simple, and the material cost and production cost are low.

[0017] 2. During the blood collection process, if the patient's limb moves or the medical staff accidentally touches the blood collector, the medical non-woven fabric will transmit the pressure to the elastic supporting piece, and since the elastic supporting piece has good elasticity, it will deform under the action of the pressure and transmit the force to the medical double-sided adhesive tape I, which will buffer the pressure under the premise of not losing the bonding with the human skin, and when the external force disappears, the elastic supporting piece will restore its original arc shape and support the medical non-woven fabric again, thereby ensuring that the catheter is not squeezed at all times and maintaining the normal flow of liquid in the catheter, and ensuring the smooth progress of the blood collection process.

[0018] 3. The isolation paper is used to prevent the adhesive surface of the medical double-sided adhesive tape I and the medical double-sided adhesive tape II from being contaminated before use, and avoid the problem that the adhesive surface of the medical double-sided adhesive tape I and the medical double-sided adhesive tape II is directly exposed to the air and easily contaminated with dust, hair and other impurities.

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0026] Please refer to Figures 1-5 The utility model provides a kind of technical scheme: a blood collector for medical examination, including needle 1, catheter 3, blood collection cylinder 4, catheter 3 is connected needle 1, blood collection cylinder 4, be provided with fixed mechanism 5 on catheter 3;

[0027] Fixed mechanism 5 includes medical non-woven fabric 501, medical double-sided adhesive tape one 502, medical non-woven fabric 501, medical double-sided adhesive tape one 502 are formed into ring and are covered on catheter 3, medical non-woven fabric 501 is located upper, medical double-sided adhesive tape one 502 is located lower, medical non-woven fabric 501 is bonded together with medical double-sided adhesive tape one 502, the lower surface of medical non-woven fabric 501 is pressed out with indentation groove 503, elastic supporting piece 504 is fixedly installed in indentation groove 503, elastic supporting piece 504 is bonded in indentation groove 503 with glue, medical non-woven fabric 501 is supported by elastic supporting piece 504, so that medical non-woven fabric 501 is not tightly pressed on catheter 3, medical non-woven fabric 501 is bonded by medical double-sided adhesive tape one 502, and then ring is formed, and medical double-sided adhesive tape one 502 can also be bonded on catheter 3, after inserting needle 1, medical non-woven fabric 501 can be pressed down, and then medical double-sided adhesive tape one 502 is pressed tightly, medical double-sided adhesive tape one 502 is bonded on human body, relative to directly using medical double-sided adhesive tape one 502 to bond catheter 3 and human body, this mode can ensure that catheter 3 is not extruded under the premise of bonding firm, ensure the flow of blood in catheter 3, overall structure is simple, and material cost and production cost are low;

[0028] The middle part of the elastic support sheet 504 is arc-shaped, and the two ends are flat sheets. The elastic support sheet 504 is an elastic copper sheet. In the initial state, the arc-shaped part supports the medical non-woven fabric 501, so that a certain space is maintained between the medical non-woven fabric 501 and the catheter 3, thereby preventing the catheter 3 from being squeezed by pressure from above. When the medical non-woven fabric 501 is pressed by external force, for example, during the blood collection process, the patient's limb moves or the medical staff accidentally touches the blood collection device, the medical non-woven fabric 501 will transmit the pressure to the elastic support sheet 504. Since the elastic support sheet 504 has good elasticity, it will deform under the action of the force and transmit the force to the medical double-sided tape 502. The medical double-sided tape 502 will buffer the pressure under the action of the force without losing adhesion to the human skin. When the external force disappears, the elastic support sheet 504 will restore its original arc shape and support the medical non-woven fabric 501 again, thereby ensuring that the catheter 3 is not squeezed at all times and maintaining the normal flow of liquid in the catheter 3, ensuring the smooth progress of the blood collection process.

[0029] The fixing mechanism 5 is provided with three, one of which is located in the middle of the catheter 3, one is close to the needle 1, and the last one is close to the blood collection barrel 4. The redundant design allows one or more medical double-sided tapes 502 in the fixing mechanism 5 to be adhered to the human body according to the needs of use, thereby fixing the catheter 3.

[0030] The outer wall of the needle 1 is rotationally provided with a butterfly page 2. The butterfly page 2 is provided with two. The butterfly page 2 is provided to facilitate the medical staff to operate the needle 1, that is, when inserting and withdrawing the needle 1, the butterfly page 2 can be pinched to operate.

[0031] The lower surface of the butterfly page 2 is adhered with a medical double-sided tape 6. After the needle 1 is inserted, the butterfly page 2 can be rotated to make the butterfly page 2 close to the human body until the medical double-sided tape 6 is adhered to the human body, thereby directly fixing the needle 1.

[0032] The length of the elastic support sheet 504 is less than the length of the medical non-woven fabric 501. The elastic support sheet 504 is located at the bottom center of the medical non-woven fabric 501, so that the lower surface of the medical non-woven fabric 501 has a large enough space to contact the medical double-sided tape 502, thereby ensuring the adhesion stability between the medical non-woven fabric 501 and the medical double-sided tape 502.

[0033] The lower surfaces of the medical double-sided tape 502 and the medical double-sided tape 6 are pasted with isolation paper 7. The isolation paper 7 is provided to prevent the adhesive surface of the medical double-sided tape 502 and the medical double-sided tape 6 from being contaminated before use. The adhesive surface of the medical double-sided tape 502 and the medical double-sided tape 6 is directly exposed to the air, which is easy to be contaminated with dust, hair and other impurities.

[0034] The outer diameters of the medical double-sided adhesive tape one 502 and the medical double-sided adhesive tape two 6 are smaller than the outer diameter of the corresponding isolation paper 7, so that the medical staff can easily tear the isolation paper 7 from the medical double-sided adhesive tape one 502 and the medical double-sided adhesive tape two 6.

[0035] Working principle: in use, the packaging bag is torn open, then the blood collector is taken out, the isolation paper 7 on one or more medical double-sided adhesive tapes one 502 is torn off, then the medical double-sided adhesive tape one 502 is pasted on the human body, the catheter 3 is fixed, the protective cover on the needle 1 is removed, then the needle 1 is inserted into the blood collection site, then blood collection is performed, after blood collection is completed, the needle 1 is pulled out, then the medical double-sided adhesive tape one 502 is peeled off from the human body, and the whole blood collector can be placed into a recycling barrel.

[0036] Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skilled in the art without making creative labor belong to the range protected by the utility model.
