Description

A dripping funnel and its infusion set

technical field

The utility model relates to the technical field of medical instruments, in particular to a drip funnel and an infusion set thereof.

Background technique

The infusion set is a sterile disposable medical consumable used for intravenous infusion to establish a channel between the vein and the liquid medicine. The infusion set is usually composed of an intravenous needle, a protective cap, an infusion hose, a liquid medicine filter, a flow rate regulator, a drip pot, a bottle stopper puncturer, and an air intake pipe air filter connection. Its working principle is: under the action of atmospheric pressure, the liquid in the bottle flows into the drip funnel along the thinner infusion hose, and when the water column pressure of the drip funnel is greater than the venous pressure, the liquid in the bottle flows into the vein along the hose.

Among them, the drip pot is an essential component of the infusion set. The drip pot relieves the pressure during the infusion process through the siphon effect and improves the safety of the infusion. Moreover, the medical staff can drip the medicinal liquid in the drip pot to judge the flow rate of the medicinal liquid. Because the inner diameter of the drip pot in the commonly used medical infusion set is greater than the inner diameter of the dropper, the medicinal liquid flows into the drip pot through the dropper and then produces air bubbles after flowing out from the liquid outlet of the drip pot. If the generated air bubbles enter the patient's body, it is easy to cause air embolism and other hazards. Therefore, when the medical personnel use the infusion set, the air bubbles in the infusion set hose must be manually discharged as far as possible.

Under normal circumstances, the method for nursing staff to clear the air is: after inserting the cork piercer into the infusion bottle stopper, first hang the dripping pot upside down, and squeeze the dripping pot by hand at the same time, so that the medicinal liquid enters the dripping pot. After the liquid is full of the drip pot, put down the drip pot quickly, so that most of the air bubbles can be removed, but some air bubbles will enter the infusion catheter; the nurse also needs to flick the infusion catheter with fingers to remove the remaining air bubbles in the infusion catheter Pop back into the drip pot to eliminate. The process of this artificial degassing is both loaded down with trivial details and time-consuming, is unfavorable for emergency infusion and rescue patient.

Utility model content

In view of the above-mentioned problems in the prior art, a drip funnel and an infusion set thereof are provided to facilitate the rapid removal of air bubbles in the infusion hose below the drip funnel.

The specific technical scheme is as follows:

A kind of dripping funnel has such characteristics, comprising: a gourd-shaped dripping pot; The bucket pot has a gourd upper body and a gourd lower body connected to the gourd upper body, and the volume of the gourd upper body is greater than that of the gourd lower body.

Furthermore, in the dropping funnel provided by the utility model, it may also have such a feature: the outer wall of the dropping funnel is covered with a light-proof shrink film.

Furthermore, in the dripping funnel provided by the present invention, it may also have such a feature: the diameter of the waist of the gourd-shaped dripping funnel pot is larger than the diameter of the dripping pipe.

Further, in the dripping funnel provided by the utility model, it may also have such a feature: the dripping funnel cover is also provided with an air outlet.

Furthermore, in the dropping funnel provided by the utility model, it may also have such a feature: both the upper body of the gourd and the lower body of the gourd are spherical.

Further, the dropping funnel provided by the present invention may also have such a feature: the height of the dropping funnel is 4 cm to 6 cm.

Further, the dropping funnel provided by the present invention may also have such a feature: the wall thickness of the dropping funnel is 0.5 mm to 0.8 mm.

In addition, the utility model also provides an infusion set, which has such a feature: it includes an infusion hose and a dripping funnel according to any one of claims 1 to 7, wherein the cavity of the infusion hose and the empty space of the dripping funnel cavities connected.

The positive effect of above-mentioned technical scheme is:

By setting the dripping pot of the dripping funnel into a gourd shape, when air bubbles appear in the infusion hose below the dripping funnel, you only need to squeeze the upper part of the gourd to remove part of the air in the dripping funnel, and the expansion of the upper body of the gourd restores During the process, the air bubbles in the infusion hose gradually move upward under the action of negative pressure, and the upper body of the gourd can be squeezed several times to quickly discharge the air bubbles in the infusion hose into the drip funnel, thus ensuring the safety of the infusion patients. The dropping funnel and the infusion set thereof have the advantages of simple structure, convenient discharge of air bubbles in the infusion hose, safety and reliability.

detailed description

In order to make the technical means, creative features, goals and effects of the utility model easy to understand, the following embodiments will specifically illustrate the dripping funnel and the infusion set provided by the utility model in conjunction with accompanying drawings 1 to 2.

As shown in Figure 1, the present embodiment provides an infusion set, which includes: a bottle stopper puncturer 1, an infusion hose 2, a flow regulator 3, a drug filter 4, an intravenous infusion needle 5, and a drip funnel 6.

Wherein, the bottle stopper puncturer 1 and the medicine filter 4 are respectively installed at the two ends of the infusion hose 2, the intravenous infusion needle 5 is connected with the liquid outlet of the medicine filter 4, and the flow regulator 3 is set on the infusion hose 2 for use. To adjust the dripping speed. And, the cavity of the infusion hose 2 communicates with the cavity of the dropping funnel 6 .

For medicines that need to be transfused under light-shielding conditions, the infusion hose 2 and drip funnel 6 can also be made of light-shielding materials, or can be obtained by wrapping the outside with a light-shielding layer on the basis of traditional PVC materials.

In addition, as shown in Figure 2, this embodiment also provides a dripping funnel 6 applied to the above-mentioned infusion set. On the top of the gourd-shaped dropping funnel pot, an exhaust port 62 is provided.

Specifically, the central position of the dripping funnel cover 61 is provided with a dripping tube 63, and the gourd-shaped dripping funnel pot has a gourd upper body 64 and a gourd lower body 65 connected to the gourd upper body 64, and the volume of the gourd upper body 64 is greater than that of the gourd lower body 65. volume.

In addition, for drugs that need to be transfused under light-proof conditions, in order to prevent drug efficacy from being reduced or lost, as a preferred technical solution, the outer wall of the dropping funnel 6 is coated with a light-proof shrink film not shown in the figure.

In this embodiment, both the gourd upper body 64 and the gourd lower body 65 are spherical, and, in order to facilitate the dropper to drop liquid smoothly, the diameter of the waist of the gourd-shaped dropping funnel is larger than the diameter of the dropper.
