Description

Technical Field

[0001] The utility model belongs to the technical field related to clinical medical examination, and particularly relates to a pollution-proof blood collection device for clinical medical examination. Background Art

[0002] Blood is the most important type of sample. Depending on the purpose of the collected blood, different substances are added to separate or preserve the blood. In clinical medical experiments, corresponding blood samples are often used for experimental work, so blood collection equipment is needed. However, it still has the following disadvantages in actual use:

[0003] 1. When the collected blood is poured into the test tube and the blood collection needle is withdrawn from the test tube, the test tube cannot be sealed after a certain period of time, which increases the possibility of blood contamination inside the test tube;

[0004] 2. The blood collection device used cannot be easily disassembled and replaced, so when the sealing structure is damaged, it cannot be quickly replaced.

[0005] Therefore, the existing blood collection equipment cannot meet the needs in actual use, so the market is in urgent need of improved technology to solve the above problems. Summary of the invention

[0006] The purpose of the utility model is to provide a contamination-proof blood collection device for clinical medical testing. By setting a sealing rubber block, the possibility of blood samples inside the collection tube being contaminated can be greatly reduced. At the same time, the assembly work of the single-mouth screw barrel and the outer screw groove can facilitate the replacement of the sealing structure.

[0007] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

[0008] The utility model is a contamination-proof blood collection device for clinical medical examination, comprising a collection tube, a pouring tube connected with the inside of the collection tube is fixed to the peripheral side wall of the upper part of the collection tube, a valve is fixed to the peripheral side wall of the pouring tube, an assembly barrel is arranged at the upper end of the collection tube, an external screw groove is opened on the peripheral side wall of the upper end of the collection tube, a single-mouth screw barrel spirally connected with the external screw groove is sleeved on the surface side of the assembly barrel, a pulling plate is arranged at the upper side of the assembly barrel, a sealing rubber block located at the inner position of the collection tube is arranged directly below the pulling plate, and the sealing rubber block is tightly fitted with the inner wall of the collection tube.

[0009] Furthermore, a plug hole is provided in the middle of the end surface of the pouring pipe, and a sealing plate which is plugged into the inner position of the plug hole is provided at the end of the pouring pipe.

[0010] Furthermore, a ring opening is provided on the peripheral side wall of the assembly cylinder, and the upper end surface of the single-port screw cylinder is slidably sleeved on the peripheral side wall of the ring opening through the opened movable opening.

[0011] Furthermore, a spring is fixed to the upper end surface of the single-port screw barrel, and the spring sliding sleeve is arranged on the peripheral side wall of the ring opening.

[0012] Furthermore, a notch is provided at the upper port of the collection tube, a sealing gasket is provided at the bottom of the notch, and an abutment tube inserted in the inner position of the notch is fixed to the lower side wall of the assembly tube.

[0013] Furthermore, a moving hole is opened on the upper side wall of the assembly cylinder, and a moving rod passing through the moving hole is fixed at the middle position of the upper side wall of the sealing rubber block.

[0014] Furthermore, a screw hole is provided at the upper end of the moving rod, and a screw rod spirally connected to the screw hole is fixed to the lower side wall of the pulling plate.

[0015] The utility model has the following beneficial effects:

[0016] 1. When the utility model is in use, when the blood sample collected by the collection needle is poured into the inner position of the collection tube, the collection needle can be inserted into the inner position of the pouring tube, and the valve can be opened to connect the collection tube with the pouring tube, and the sealing rubber block is driven by the pulling plate to move from the inner position of the collection tube to the upper position of the pouring tube. At this time, the blood sample collected by the blood collection needle can flow into the inner position of the collection tube from the position of the pouring tube, and the pulling plate is first moved downward to make the sealing rubber block seal and block the connection position between the pouring tube and the collection tube, and then the blood collection needle can be pulled out at the position of the pouring tube, so that in the process of squeezing the blood sample inside the blood collection needle into the interior of the collection tube, the interior of the collection tube can be ensured to be in a closed space, thereby greatly reducing the possibility of the blood sample inside the collection tube being contaminated.

[0017] 2. When the utility model is in use, when disassembling the assembly barrel, the single-port screw barrel can be spirally moved upward at the position of the ring mouth, so that the single-port screw barrel will compress the spring, thereby separating the single-port screw barrel from the spiral connection with the external screw groove, and the upper end position of the assembly on the collection tube can be directly removed, thereby facilitating the replacement of the plugging structure.

[0018] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
