Abstract

The invention relates to the technical field of transfusion bottle, in particular to a blood return proof transfusion bottle. The blood return proof transfusion bottle comprises a bottle body which is provided with a bottle opening and a sheet which is has buoyant; the bottle opening of the bottle body is provided with a bottle stopper which is matched with the bottle opening; a plurality of pins are arranged at the peripheral edge of the sheet; the pins are arranged between the internal walls of the bottle opening and the bottle stopper; the pins are fixed between the internal wall of the bottle opening and the bottle stopper and the middle of the sheet is provided with a hollow projection when the bottle stopper is inserted into the bottle opening of the bottle body. According to the blood return proof transfusion bottle, the float sheet is arranged inside the transfusion bottle, puncture outfit is blocked due to the fact that the sheet floats on the fluid level and decreases along with the fluid level and a blood return proof purpose is achieved, the structure is simple, costs are low, and the blood return problem due to the fact that syringe needle is pulled out untimely when transfusion is finished is effectively solved.

Description

Anti-reflux infusion bottle

technical field

The invention relates to the technical field of transfusion bottles, in particular to a blood return preventing transfusion bottle.

Background technique

Infusion is one of the basic methods of treating diseases at present. The current infusion set is basically a disposable infusion set, which is a disposable consumable used to establish a channel between the vein and the liquid medicine. The bottle of the liquid that is configured, when the traditional ordinary infusion set is used up, if the care is not proper, air will enter the infusion set and cause blood back phenomenon. If the blood meets the air, it will cause thrombus, which will lead to some The occurrence of adverse consequences is likely to cause panic in patients, which is not conducive to the treatment of patients.

Contents of the invention

The technical problem to be solved by the present invention is: in order to overcome the problem that the blood return will be caused if the needle is not pulled out in time after the transfusion is finished, a blood return preventing transfusion bottle is now provided.

The technical solution adopted by the present invention to solve the technical problem is: an anti-blood transfusion bottle, which includes a bottle body with a bottle mouth, a bottle stopper that matches the bottle body, and a buoyant Thin slices, the edges of the thin slices are provided with several pins, the pins are located between the inner wall of the bottle mouth and the bottle stopper, and when the bottle stopper is inserted into the mouth of the bottle body, the pins are fixed on the inner wall of the bottle mouth and the bottle stopper In between, when there is liquid in the infusion bottle, the flakes float in the liquid, and when the liquid level drops to the position where the flakes normally float, as the liquid level drops, the flakes will also drop with the liquid level until the liquid level is lower than When the puncture device of the infusion set is used, the thin sheet will wrap the head of the puncture device closely, and isolate the infusion set from the air to achieve the purpose of preventing blood return.

In order to make the sheet just above the bottle stopper in the infusion bottle and the protrusion can be blocked on the through hole of the piercer, further, the middle part of the thin sheet has a hollow protrusion.

Preferably, there are four pins and they are evenly distributed.

Preferably, the hollow protrusion is spherical.

The beneficial effect of the present invention is: the present invention installs floating flakes in the infusion bottle, the flakes float on the liquid surface and drop together with the liquid level, and finally block the puncture device to prevent blood return. The present invention has simple structure and low cost , effectively solved the problem of blood returning caused by not pulling out the needle in time after the infusion.

Description of drawings

The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

Fig. 1 is the concrete implementation schematic diagram of anti-blood infusion bottle of the present invention;

In the figure: 1, bottle body, 1-1, bottle mouth, 2, pin, 3, bottle stopper, 4, piercer, 5, sheet, 6, hollow protrusion.

Detailed ways

The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

Example 1

As shown in Figure 1, an anti-blood transfusion bottle includes a bottle body 1 with a bottle mouth 1-1, a bottle stopper 3 matching it is also provided in the bottle mouth 1-1 of the bottle body 1, and a buoyant sheet 5 is also included. , the edge of the sheet 5 is provided with some pins 2, and the pins 2 are located between the inner wall of the bottle mouth 1-1 and the bottle stopper 3, and the pins are inserted when the bottle stopper 3 is inserted into the bottle mouth 1-1 of the bottle body 1. 2 is fixed between the bottle mouth 1-1 inner wall and the bottle stopper 3.

Example 2

As shown in Figure 1, the difference between embodiment 2 and embodiment 1 is that the middle part of the sheet 5 has a hollow protrusion 6, the hollow protrusion 6 is spherical, and there are four pins 2 that are evenly distributed.

Embodiment 1 and 2 working principles:

When there is liquid in the infusion flat bottle, the sheet 5 floats in the liquid. After the infusion starts, when the liquid level drops to the position where the sheet 5 normally floats, as the liquid level drops, the sheet 5 will also drop along with the liquid level until When the liquid level is lower than the piercer 4 of the infusion set, the sheet 5 will wrap the head of the piercer 4 and fit the infusion set from the air. The hole is blocked to achieve the purpose of preventing blood return.

Inspired by the above-mentioned ideal embodiment according to the present invention, through the above-mentioned description content, relevant workers can make various changes and modifications within the scope of not departing from the technical idea of the present invention. The technical scope of the present invention is not limited to the content in the specification, but must be determined according to the scope of the claims.
