Abstract

The utility model discloses a sealing device used in arterial blood drawing. The sealing device used in arterial blood drawing comprises a base, grooves are formed in the upper surface of the base, and plugs made of elastic materials are embedded in the grooves. Each plug is composed of a cylindrical section and a truncated conical section, each cylindrical section is embedded in the groove, the truncated conical section is provided with a larger lower portion and a smaller upper portion, and a locating slot is formed in the top of the truncated conical section. The sealing device used in the arterial blood drawing is reasonable in design, simple in structure and easy to manufacture. Materials are saved as the plug is designed in such a shape, the contact area of a syringe needle and the plug is large, the syringe needle can prick into the plug easily, the opportunity of holding the plug is decreased, the risk that a hand is stabbed is decreased, preparation time is saved, and work efficiency is improved.

Description

Extract the arterial blood sealing device

Technical field

This utility model belongs to technical field of medical instruments, particularly a kind of extraction arterial blood sealing device.

Background technology

When doing blood gas analysis extraction arterial blood, use the skin plug to stop up syringe needle at present, and how irregular clinical used skin plug is numerous and diverse and, and just interim the making taken other skin plugs product as an alternative, as calparine cap, bottle stopper, syringe skin plug, rather than special-purpose article with strong points.Because the skin plug is not special-purpose article, one can not guarantee that it is aseptic, influences the accuracy of sample; Two increase nursing staff's operational hazards, thrust skin Sai Shiyi at syringe needle and stab the finger of holding the skin plug.In addition, owing to this operation requires to extract the specimen censorship in the short time, thus not only require the nursing staff skilled, and need a kind of suitable operation tool badly and assist the shortening operation consuming time, increase work efficiency, increase the accuracy of chemical examination.

The utility model content

This utility model is in order to solve weak point of the prior art, and the extraction arterial blood sealing device of a kind of safe and reliable, sanitation and hygiene, high efficiency is provided.

For solving the problems of the technologies described above, this utility model adopts following technical scheme: extract the arterial blood sealing device, comprise base, base upper surface is provided with groove, and groove is embedded in the stopper of being made by elastomeric material.

Described stopper is made up of cylindrical section and round platform section, and cylindrical section is embedded in the groove, and the round platform section is the big minor structure that goes up down, and the top of round platform section is provided with locating slot.

Described base is the square shape, and in the equal arc transition setting in four vertical edges and corners of base, the groove vertical and horizontal on the base are uniform at least respectively to arrange three.

Adopt technique scheme, have following beneficial effect:

1, one-handed performance, be difficult for stabbing: it is locating slot that this utility model has the plane that contacts with syringe needle specially, and in need not be hand held stopper when using, be placed directly on plane or the base, one hand is held syringe and is thrust and get final product, and can reduce in the past Yin Pisai (aspect such as shape) the little and easy mistake of area lack of standardization, that can thrust and sting, pierces through stabbing of initiation.

2, aseptic: this utility model has outer package, and in the past because of the extensive aseptic that can not guarantee stopper of drawing materials, this utility model passes through the strictness control of manufacturing process, the tightness of packing, the standard of plug and play, to improve the accuracy that blood sample is chemically examined.

1., set-up procedure is short, and stopper with strong points has been arranged 3, operate weak point consuming time:, noting be used in wastes time and energy in the set-up procedure seeks proper object as thrusting thing; 2., with respect to existing skin plug because be not articles for use targetedly, not with the suitable face that thrusts of syringe needle, can hinder the smoothness of operation and length consuming time, and this design helps to thrust rapidly and increase work efficiency.

4, intensive use: design the supporting base of a stopper therewith, groove on the base can hold at least nine stoppers simultaneously, so that when a large amount of the use, places a plurality of stoppers simultaneously on a cover base, time when having reduced continuous the use, improved work efficiency.

5, economical and practical: 1., shape is beneficial to the saving material: the design adopts up-small and down-big circular platform type, has both guaranteed the operations necessary area, and has reduced the consumptive material on top; 2., the design's material therefor draws materials extensively, cheap with thing, cost is few.

This utility model is reasonable in design, simple in structure, be easy to make, and the shape of stopper is saved material, and the area that syringe needle can contact with stopper is big, easily thrusts, and reduces the chance of hand-held stopper, reduces the rate of stabbing, and saving time, increases work efficiency.

Fig. 1 is structural representation of the present utility model;

Fig. 2 be among Fig. 1 base along the cross sectional representation at groove center;

Fig. 3 is the structural representation of stopper in the middle of Fig. 1.

The specific embodiment

As Fig. 1, Fig. 2 and shown in Figure 3, extraction arterial blood sealing device of the present utility model comprises base 1, and base 1 upper surface is provided with groove 2, and groove 2 is embedded in the stopper of being made by elastomeric material (as rubber, rubber etc.) 3.Stopper 3 is made up of cylindrical section 4 and round platform section 5, and cylindrical section 4 is embedded in the groove 2, and round platform section 5 is the big minor structure that goes up down, and the top of round platform section 5 is provided with locating slot 6, and locating slot 6 is that syringe needle thrusts label range.Base 1 is the square shape, and in the equal arc transition setting in four vertical edges and corners of base 1, groove 2 vertical and horizontal on the base 1 are uniform at least respectively to arrange three, and present embodiment arranges nine grooves 2.

This utility model in use, stopper 3 is placed on desktop or is located in the middle of the groove 2 on the base 1, the staff draws blood and finishes the back one hand and hold syringe needle and aim at locating slot 6 upside down and thrust stopper 3 and get final product, then the stopper of pricking on syringe and the syringe needle 3 is together kept flat to wait in the treatment dish inspecting by ready samples and get final product.
