Description

Technical Field

[0001] The utility model relates to a disposable medical appliance, in particular to a blood sampling device suitable for blood sampling in a dialysis machine pipeline. Background Art

[0002] During the hemodialysis process, when patients need to measure blood sugar or blood routine tests, they need to draw blood from the blood collection port of the hemodialysis pipeline. The current blood collection equipment is a disposable blood collection device (venous blood collection device, vacuum blood collection tube) or a disposable syringe. When the needle is inserted into the blood collection port or the needle is removed, blood will leak from the blood collection port, which will not only pose a serious threat to the health of medical staff, but also may cause infection of various blood-borne diseases if the blood contacts the skin or mucous membranes. At the same time, the leaked blood may also contaminate the bed sheets. If the contaminated bed sheets are not properly handled in time, they may become a breeding ground for bacteria, further increasing the risk of infection for patients and medical staff.

[0006] The finger grip is made of medical transparent material.

[0007] The conical sleeve is made of medical transparent material.

[0008] The elastic sealing sleeve is made of medical transparent elastic material.

[0009] The elastic suction ball is made of medical transparent elastic material.

[0010] A first connecting protrusion is arranged on the lower side of the finger grip, and the elastic sealing sleeve is sleeved on the first connecting protrusion.

[0011] A second connecting protrusion is arranged on the upper side of the finger grip, and the lower end of the conical sleeve is connected to the upper end of the second connecting protrusion.

[0012] The finger grip is provided with a plurality of grooves along the edge.

[0013] The inner side wall of the elastic sealing sleeve is provided with absorbent cotton.

[0014] The side wall of the conical sleeve is provided with a plurality of observation holes.

[0015] The beneficial effects of the utility model are as follows: the blood collection device of the utility model comprises a finger grip, a conical sleeve, an elastic sealing sleeve, an elastic suction ball and a needle with a needle seat. When collecting blood, the finger grip is held by the finger, the finger is bent and the palm is squeezed to squeeze the elastic suction ball. The elastic suction ball is squeezed to exhaust air and shrinks in the conical sleeve. Then the needle is inserted into the blood collection port on the dialysis machine pipeline. Then the finger is stretched and the palm is separated from the elastic suction ball. The elastic effect of the elastic suction ball naturally recovers and absorbs blood. When collecting blood, the elastic sealing sleeve first contacts with the blood collection port to seal the blood collection site. Then, the needle is pushed forward continuously and the elastic sealing sleeve is deformed before piercing the blood collection site. After the blood collection is completed, the needle leaves the blood collection site first, and then the elastic sealing sleeve leaves the blood collection site. The operation is convenient and can effectively prevent the blood leaked during the insertion and withdrawal of the needle from flowing out and causing pollution. BRIEF DESCRIPTION OF THE DRAWINGS
