Problems solved by technology

[0004] 2. Since the blood collection needle penetrates the human skin, a disposable blood collection needle must be used to prevent infection
When blood is collected by the tester, in the process of separating the disposable blood collection needle from the blood collection device, due to negligence or improper application of force, the hand of the tester may come into contact with the blood collection needle, or be stained with the blood of the person to be lancet. The blood collection needle was punctured, so there is a possibility of being infected by germs
[0005] 3. Since there is no safety device or self-destruction device, the blood collection needle after blood collection may be recycled and reused by criminals

Embodiment 1

[0040] This embodiment provides a blood collector, including a blood collection needle 1 and a base 2, the base 2 is a cylindrical structure, the cylindrical structure is coaxially provided with a blood circulation channel communicating with the blood collection needle 1, the bottom end of the blood collection needle 1 It is integrally installed on the top end surface of the base 2, and also includes casing I3 and casing II4, both of which are linear circular tubes, and the inner diameter of the axial perforation of casing I3 is the same, and the shaft of casing II4 The inner diameter of the perforation is the same.

[0041] One axial end of the casing I3 is open and the other axial end is closed. A through hole 5 is opened on the closed end of the casing I3. The center of the through hole 5 coincides with the axis of the casing I3. One axial end of the casing II4 is open and the other axial end is closed. The open end of the casing II4 extends into the casing I3 along the thr...

Embodiment 2

[0048] Further improvement on the basis of Example 1, the outer end surface of the closed end of the sleeve I3 is provided with an annular locking groove 11, and the annular locking groove 11 is coaxially arranged with the through hole 5; the bottom end surface of the limiting ring plate 7 is provided with an annular The protrusion, the annular protrusion fits into the annular locking groove 11 to realize the fixed connection between the sleeve II4 and the sleeve I3. The fixed connection between the casing I3 and the casing II4 is realized by fitting the annular projection into the annular slot, such as an interference fit.

[0049] The adsorption layer 8 adopts a sponge adsorption layer, the diaphragm layer 9 adopts an elastic rubber layer, and the liquid glue layer 10 is a normal temperature curing liquid glue layer, and the liquid glue layer 10 can adopt an existing normal temperature fast curing glue. By setting the elastic rubber layer as the diaphragm layer 9, after the ...

Embodiment 3

[0051] Further improvement on the basis of embodiment 2, further includes an adapter 12, the adapter 12 has a cylindrical structure, one end surface of the adapter 12 is provided with a mounting hole 13, and the adapter 12 is coaxially provided with a channel for blood circulation . The other end of the adapter 12 is used for connecting the hose, and the other end of the hose is used for connecting the puncture needle.

[0052] The free end of the base 2 extends into the installation hole 13, and the free end surface of the base 12 is in sealing contact with the inner bottom surface of the installation hole 13, such as sealing by a sealing ring on the contact surface; the outer wall of the base 2 is also sleeved with a fastening shaft Sleeve 14, the inner wall of fastening shaft sleeve 14 is rigidly connected and fixed on the outer wall of base 2, and the bottom outer wall of fastening shaft sleeve 14 is threadedly connected with the inner wall of mounting hole 13; On the top...

Abstract

The invention discloses a blood collector which comprises a blood taking needle and a base. One axial end of a sleeve I is open, the other axial end of the sleeve I is closed, and a through hole is formed in the end face of the closed end of the sleeve I; one axial end of a sleeve II is open, the other axial end of the sleeve II is closed, the open end of the sleeve II extends into the sleeve I along the through hole in the sleeve I, a guide ring plate is annularly arranged on the outer wall of the open end of the sleeve II in the circumferential direction, the outer circumferential wall of the guide ring plate is in sliding contact with the inner wall of the sleeve I in the axial direction, and the outer diameter of the guide ring plate is smaller than that of the through hole. A limitingring plate is arranged on the outer wall of the closed end of the sleeve II in the circumferential direction, and the outer diameter of the limiting ring plate is larger than the inner diameter of the through hole. An adsorption layer, a diaphragm layer and a glue layer are sequentially arranged in the sleeve II from the open end to the closed end. The blood collector is simple in structure, theblood taking needle can be conveniently, rapidly and effectively recycled, and the problem that the exposed blood taking needle causes crossed infection after use is solved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a blood collector. Background technique [0002] Blood collection is one of the essential items when performing physical examination or treatment in a hospital. Blood collection requires the use of a venous blood collection device. Currently, the existing venous blood collection devices on the market are generally composed of a plug puncture needle, a catheter, and a venipuncture needle. After the sheath is pulled out, the needle tip of the venous blood collection needle is exposed after the medical staff completes the blood collection. The following problems exist during the operation: [0003] 1. After the blood collection is completed, because the needle tip is exposed outside without any protective measures, the medical staff may be slightly careless in the operation, and they are easily stabbed by the needle tip of the contaminated venipuncture needle, resulting ...
