Description

Automatic cut-off transfusion device

Technical Field

The utility model relates to the technical field of medical appliances, in particular to an automatic cutoff transfusion device.

Background

The infusion set is a common medical consumable, and a channel between a vein and liquid medicine is established for intravenous infusion through aseptic treatment.

An automatic cut-off transfusion device is disclosed in the examined Chinese patent application No. CN200920026783.5, which belongs to the field of medical appliances. Is provided with an upper pipe, a lower pipe and a liquid storage pipe connected between the upper pipe and the lower pipe, and is characterized in that: the floating ball is arranged in the liquid storage pipe, the floating ball is provided with a handle, the upper part of the handle is a cylinder, the lower part of the handle is a cone, and the diameter of the section of the cylinder at the upper part of the handle is the same as the inner diameter of the lower pipe. The utility model completely realizes automatic flow cutting, has simple structure and safe and convenient use, and can thoroughly relax the rest of patients during transfusion.

However, when the device is used, when the placement angle of the liquid storage tube is inclined (for example, as shown in fig. 4 of the drawings), the handle on the floating ball may not smoothly enter the lower tube, and thus the effect of cutting off the infusion apparatus may not be achieved.

Disclosure of Invention

The utility model aims to solve the defect that when the placement angle of a liquid storage tube is inclined, a handle on a floating ball can not smoothly enter a lower tube, so that the effect of cutting off the infusion set can not be achieved.

In order to achieve the above purpose, the present utility model adopts the following technical scheme:

the utility model provides an automatic cutout transfusion system, includes the stock solution pipe, upper and lower both ends of stock solution pipe are installed respectively and are gone up pipe and down the pipe, fixed mounting has a spacing section of thick bamboo on the inside diapire of stock solution pipe, the inside of spacing section of thick bamboo with down the pipe is linked together, a plurality of weeping grooves have been seted up on the spacing section of thick bamboo lateral wall, the inside activity of spacing section of thick bamboo is provided with the floating column, and the floating column is followed the water line and is reciprocated, can be along with the mouth of pipe of water pipe is closed down automatically when the liquid medicine is not enough when the water line descends.

The technical scheme further comprises the following steps: the diameter of the floating column is larger than the inner diameter of the lower pipe.

Compared with the prior art, the utility model has the beneficial effects that:

according to the utility model, the floating column can move along with the position of the water line in the liquid storage tube, so that when the liquid medicine in the liquid storage tube is insufficient, the tube orifice of the lower tube is automatically closed, the effect of cutting off the infusion set is achieved, meanwhile, the floating column can stably enter the lower tube through the limiting tube, the phenomenon that the floating column cannot enter the lower tube to close the lower tube when the liquid storage tube is obliquely placed is avoided, and the stability of the floating column cutting-off effect is improved.

Detailed Description

The technical scheme of the utility model is further described below with reference to the attached drawings and specific embodiments.

Example 1

Referring to fig. 1-4, the automatic flow-stopping transfusion device provided by the utility model comprises a liquid storage tube 10, wherein an upper tube 11 and a lower tube 12 are respectively arranged at the upper end and the lower end of the liquid storage tube 10, the part, which is not shown, of the upper end of the upper tube 11 and the part, which is not shown, of the lower end of the lower tube 12 are not improved, the structure of the automatic flow-stopping transfusion device is still clear to a person skilled in the art, and the structure is not repeated.

The internal bottom wall of the liquid storage tube 10 is fixedly provided with a limiting cylinder 20, the inside of the limiting cylinder 20 is communicated with the lower tube 12, wherein the limiting cylinder 20 is of a cylindrical structure with a hollow middle part, the top of the limiting cylinder is closed, and the bottom of the limiting cylinder is communicated with the lower tube 12.

The side wall of the limiting cylinder 20 is provided with a plurality of liquid leakage grooves 21, the liquid leakage grooves 21 can be uniformly formed in the side wall of the limiting cylinder 20, the number of the liquid leakage grooves can be 2 or 4, the inside of the limiting cylinder 20 is movably provided with floating columns 22, the floating columns 22 move up and down along with the water level, and when the liquid medicine is insufficient, the mouth of the lower pipe is automatically closed along with the falling of the water level.

The diameter of the float column 22 is greater than the inner diameter of the down tube 12, i.e., when the bottom wall of the float column 22 reaches the bottom of the stopper cylinder 20, the bottom wall of the float column 22 completely covers the opening of the down tube 12.

In this embodiment, the working principle of the device is as follows: when the liquid in the upper pipe 11 flows into the liquid storage pipe 10 during transfusion, the liquid enters the limiting cylinder 20 through the liquid leakage groove 21, the floating column 22 floats upwards along with the inflow of the liquid, so that the opening of the lower pipe 12 is opened, at the moment, the liquid medicine can enter the lower pipe 12 from the top opening of the lower pipe 12, and at the moment, normal transfusion can be performed;

when the liquid medicine in the liquid medicine bottle is completely infused, the liquid level in the liquid medicine pipe 10 gradually moves downwards, namely the liquid level in the limiting cylinder 20 moves downwards, the floating column 22 moves along with the downward movement of the liquid level at the moment, when the bottom wall of the floating column 22 contacts with the top opening of the lower pipe 12, the bottom wall of the floating column 22 seals the top opening of the lower pipe 12, the liquid level is at the position shown in figure 3 at the moment, and the lower pipe 12 is sealed, so that the damage to the human body caused by the air entering the human body after the liquid in the limiting cylinder 20 flows completely is avoided;

after the medical staff changes a new liquid medicine bottle, the liquid storage tube 10 is extruded, so that the liquid medicine water level line in the liquid storage tube 10 rises again, and the floating column 22 can be driven to be far away from the top opening of the lower tube 12, and then the transfusion can be performed again.

The foregoing is only a preferred embodiment of the present utility model, but the scope of the present utility model is not limited thereto, and any person skilled in the art, who is within the scope of the present utility model, should make equivalent substitutions or modifications according to the technical scheme of the present utility model and the inventive concept thereof, and should be covered by the scope of the present utility model.
