Description

Improved generation heparin tube block

Technical Field

The utility model relates to the technical field of medical equipment, especially, relate to an improved generation heparin tube block cap.

Background

The blood collector is one kind of medical article for collecting venous blood for test. The hemostix is a major improvement of the traditional blood sampling mode, and the blood sampling procedure is completed under a totally closed system, so the possibility of blood pollution and cross infection is fundamentally eliminated; and has been widely popularized and popularized due to simple structure and convenient use. The blood collector consists of a blood collecting tube, a blood collecting needle and a needle holder, wherein the blood collecting tube is the main component of the blood collector and is mainly used for collecting and preserving blood samples. A certain amount of negative pressure is preset in the production process of the blood sampling tube, and after the blood sampling needle punctures into a blood vessel, blood automatically flows into the blood sampling tube due to the action of the negative pressure in the blood sampling tube.

The constitution of heparin tube includes heparin tube body and stopper cap, and the stopper cap comprises plug and block, and for guaranteeing that heparin tube is originally internal, the plug seals up tightly at heparin tube body suitable for reading, and the block is outside plug and heparin tube body suitable for reading. At present, the commonly used cap of the existing blood sampling tube has the following problems that 1, the sealing performance and the stability between the cap and the rubber plug are poor, the cap and the rubber plug are easy to separate when in use, and the inconvenience occurs to medical staff in the use process; 2. the current block only sets up the fixture block at the block inner wall, is convenient for with test tube card between the block, and this kind of structure appears needing to energetically just can separate test tube and block easily when separating the block, when not controlling good dynamics, the inside blood spill of test tube easily appears, causes unnecessary trouble and waste.

SUMMERY OF THE UTILITY MODEL

In order to solve the defects existing in the prior art, the utility model provides an improved generation heparin tube block cap.

The technical scheme of the utility model is realized like this:

the utility model provides an improved generation heparin tube block, its characterized in that, includes the open tube-shape block main part in both ends, the inner wall of block main part has an annular supporting shoe by the top, still have fixed muscle on the block main part inner wall, fixed muscle is located the lower extreme of supporting shoe, the both sides of fixed muscle are equipped with the strengthening rib, vertical anti-skidding line and horizontal anti-skidding line have on the outer wall of block main part.

In the improved blood collection tube cap of the present invention, the annular supporting block has a plurality of notches.

The utility model discloses an in this kind of improved generation heparin tube block, spherical bulge has on the inner wall of block main part, spherical bulge is in the upper end of annular supporting shoe.

In the improved blood collection tube cap of the present invention, the fixing ribs and the reinforcing ribs are cone-shaped with a small lower end and a large upper end.

Implement the utility model discloses a this kind of improved generation heparin tube block has following beneficial effect: 1. this improved generation heparin tube block simple structure, design benefit, simple to operate, and the stability between block and the plug is good, is difficult for droing.

2. Through set up the fixed muscle and the strengthening rib of the vertebra bodily form on block main part inner wall and fix the test tube, can enough be in the same place the test tube is stable with the block is fixed, can also not need great dynamics alright with separating test tube and block main part when separation test tube and block main part, the phenomenon of the blood spill in the test tube when having prevented test tube and block main part separation.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

As shown in fig. 1 to 6, the utility model discloses an improved generation heparin tube block, including the open tube-shape block main part 10 in both ends, the inner wall of block main part 10 leans on the top to have an annular supporting shoe 11, and annular supporting shoe 11 is for supporting plug 12, and the lower extreme of plug 12 inserts in test tube 13, so set up annular supporting shoe 11 on the inner wall of block main part 10. The annular supporting block 11 is provided with a plurality of notches 14, and the diameter of the lower end part of the rubber plug 12 is slightly larger than the inner diameter of the annular supporting block 11, so that the rubber plug 12 can be fixed on the annular supporting block 11. After the rubber plug 12 is inserted between the annular support blocks 11, since the rubber plug 12 is made of an elastic material, the rubber plug 12 is squeezed after the rubber plug 12 is inserted into the annular support blocks 11, so that a part of the rubber plug 12 is sunk into the gap 14.

Further, a spherical boss 15 is provided on the inner wall of the cap body 10, and the spherical boss 15 is provided at the upper end of the annular support block 11. The spherical convex part 15 can further fix the rubber plug 12.

Still have fixed muscle 16 on the block main part 10 inner wall, fixed muscle 16 is located the lower extreme of annular supporting shoe 11, and the both sides of fixed muscle 16 are equipped with strengthening rib 17, and strengthening rib 17 is used for fixing fixed muscle 16, reinforcing stability. The fixed rib 16 and the reinforcing rib 17 are in a cone shape with a small lower end and a large upper end. When it is necessary to insert the test tube into the cap body, since the lower end of the fixing rib is small and the upper end is large, the test tube 13 is more firmly fixed as it is inserted, and thus the test tube 13 can be inserted or separated with less force.

The cap body 10 has vertical and horizontal

non-slip threads

18 and 19 on the outer wall thereof. Only have vertical anti-skidding line 18 in the existing design, this kind of mode appears the slip phenomenon easily when separating test tube 13 and block main part 10, is difficult for separating test tube 13 and block main part 10. And the transverse anti-slip grains 19 and the vertical anti-slip grains 18 are matched for use, so that the phenomenon can be effectively prevented, and the rotation and the separation in the vertical direction can be facilitated.

The above description is only for the preferred embodiment of the present invention and should not be taken as limiting the invention, and any modifications, equivalent replacements and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
