Description

Spiral tube type precision infusion set

technical field

The utility model relates to an infusion set, in particular to a spiral tube precision infusion set.

Background technique

At present, infusion is a common means in medical treatment. During infusion, the drip rate is adjusted through the infusion set, and it enters the vein continuously and stably to replenish body fluids, electrolytes or provide nutrients. The infusion sets used for infusion have fixed lengths. Suspending the infusion bag or bottle at a suitable height according to the length of the infusion set relies heavily on the structure of the infusion stand, and when the hanging position of the infusion bag or bottle is fixed, the patient's limb activities are greatly restricted, which brings great harm to the patient. Major inconvenience.

Utility model content

Therefore, the purpose of this utility model is to provide a helical tube type precision infusion set, the length of the precision infusion set can be adjusted within a certain range by utilizing the stretchability of the helical tube, reducing the dependence on the infusion stand and reducing the patient's limb activity. restrictions for ease of use.

The spiral tube type precision infusion set of the utility model comprises a bottle stopper puncturer, a drip pot, a liquid medicine filter and a venous needle which are connected in sequence through an infusion hose; wherein at least the liquid medicine filter and the venous needle are connected Some pipe sections of the infusion hose are spiral pipes.

Further, the spiral tube is a cylindrical helical structure.

Further, a flow rate regulator is installed on the infusion hose between the spiral tube and the venous needle.

Further, the venous needle is covered with a protective cap.

Further, there are at least two cork piercers.

The beneficial effects of the utility model are: the helical tube type precision infusion set of the utility model can adjust the length of the precision infusion set within a certain range by utilizing the telescoping performance of the spiral tube, reducing the dependence on the infusion stand and at the same time reducing the pressure on the patient's limbs. Activities are restricted for ease of use.

Description of drawings

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

detailed description

Fig. 1 is a schematic structural view of the utility model, as shown in the figure: the spiral tube type precision infusion set of the present embodiment includes a cork puncturer 1, a dripping pot 2, and a liquid medicine filter connected in sequence through an infusion hose. device 3 and venous needle 4; wherein at least part of the infusion hose section connecting the liquid medicine filter 3 and the venous needle 4 is a spiral tube, and the attachable part of the spiral tube 5 tube wall is fixedly provided with multiple pairs of heteropolar magnetic sheets , the use of the adsorption function of the magnetic sheet can ensure the structural stability of the spiral tube 5 to a certain extent after shrinkage, and avoid the stretching of the spiral tube 5 due to the gravity of itself and its internal medicine solution. It is necessary to stretch the spiral tube 5 slightly. Just add external force to overcome the suction force of the magnetic sheet, which is convenient to use.

In this embodiment, the spiral tube 5 is a cylindrical helical structure with a large stretching length and good performance.

In this embodiment, a flow rate regulator 6 is installed on the infusion hose between the spiral tube 5 and the venous needle 4, and the infusion hose between the cork puncturer 1 and the drip pot 2 is a straight tube, which is convenient to cooperate with the infusion pump. Perform an infusion.

In this embodiment, the venous needle 4 is covered with a protective cap 7 .

In this embodiment, there are at least two cork piercers 1, and the infusion hose connecting the two cork piercers 1 and the dripping pot 2 is a three-way pipe structure, and multiple infusion bags can be connected for infusion as required .
