Problems solved by technology

[0002] Currently, skin plugs are used to block needles when blood gas analysis is used to draw arterial blood. However, the skin plugs used in clinical practice are complicated and irregular, and are only made temporarily. Other plugs are used as substitutes, such as heparin caps, bottle stoppers, and syringe plugs. , rather than highly targeted specialized items
Because the skin plug is not a special item, firstly, its sterility cannot be guaranteed, which affects the accuracy of the sample; secondly, it increases the operating risk of the nursing staff, and it is easy to prick the finger holding the skin plug when the needle is inserted into the skin plug

Embodiment Construction

[0017] like figure 1 , figure 2 and image 3 As shown, the sealing device for extracting arterial blood of the present invention includes a base 1, a groove 2 is provided on the upper surface of the base 1, and a plug 3 made of elastic material (such as rubber, rubber, etc.) is embedded in the groove 2. The stopper 3 is composed of a cylindrical section 4 and a circular platform section 5. The cylindrical section 4 is embedded in the groove 2. The circular platform section 5 has a large bottom and a small upper structure. The top of the circular platform section 5 is provided with a positioning groove 6. into the marked range. The base 1 is in the shape of a cube, and the four vertical corners of the base 1 are provided with circular arc transitions. The grooves 2 on the base 1 are arranged at least three evenly in the vertical and horizontal directions respectively. In this embodiment, nine grooves 2 are provided.

Abstract

The invention discloses a sealing device for drawing arterial blood. The sealing device for drawing arterial blood comprises a base, a groove is formed in the upper surface of the base, and a plug made of elastic material is embedded in the groove. The plug is composed of a cylindrical section and a cone frustum section, wherein the cylindrical section is embedded in the groove, the cone frustum section is of a big-end-down structure, and a positioning groove is formed in the top of the cone frustum section. The sealing device for drawing arterial blood is reasonable in design, simple in structure and easy to manufacture, material is saved due to the shape of the plug, the contact area of a needle and the plug is large so that the needle can make a puncture easily, the chance to hold the plug by hand is reduced, the puncture ratio is lowered, preparation time is saved, and working efficiency is promoted.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a sealing device for extracting arterial blood. Background technique [0002] Currently, skin plugs are used to block needles when blood gas analysis is used to draw arterial blood. However, the skin plugs used in clinical practice are complicated and irregular, and are only made temporarily. Other plugs are used as substitutes, such as heparin caps, bottle stoppers, and syringe plugs. , rather than highly targeted special items. Because the skin plug is not a special item, one cannot guarantee its sterility, which affects the accuracy of the sample; two, it increases the operating risk of the nursing staff, and it is easy to prick the finger holding the skin plug when the needle is inserted into the skin plug. In addition, since this operation requires specimens to be collected and sent for inspection in a short time, not only skilled nurses are required, but also a sui...
