Description

A medicine droplet-proof empty infusion set

technical field

The utility model relates to a medicinal liquid transfusion device, in particular to a medicinal liquid droplet-proof transfusion device.

Background technique

Currently commonly used infusion sets generally include intravenous needles, protective caps, infusion hoses, flow rate regulators, and drip pots. The control and adjustment of the liquid medicine in the infusion tube. However, when the liquid in the infusion bottle or bag is empty, air may enter the patient's blood vessels from the infusion tube, which may cause air embolism in severe cases, and may also cause the patient's blood to flow back from the infusion tube to the infusion tube or even In the infusion bottle or bag, no matter that kind of situation all has certain injury for the patient's health.

Especially when there is a special situation, such as the infusion patient is a baby, the existing infusion set obviously shows its disadvantages, because the baby's body is small, so the baby's input amount of the medicinal solution is very small in a certain period of time. There are strict restrictions, so sometimes it is necessary to choose intermittent or crossover methods during treatment.

And if adopt existing infusion set to carry out infusion then may cause because changing medicinal liquid not in time causes in the infusion hose to enter air, causes irreversible situation. For this reason, the patent name is a kind of anti-medicine droplet empty infusion device, and the utility model with the application number 201520105287.4 discloses an infusion device that can basically solve the problem, but the flow stop device inside is easy to deviate and cannot completely cover the infusion hose, resulting in no anti-drug droplet emptying.

Utility model content

The purpose of the utility model is to solve the problem that the existing infusion set cannot avoid emptying, and provide an anti-medicine droplet emptying infusion set.

The technical scheme of the utility model is specifically:

An empty infusion device for preventing drug droplets. The infusion device includes an intravenous needle, an infusion hose, a flow rate regulator and a drip pot. One end of the infusion hose is connected to the drip pot, and the other end of the infusion hose passes through the flow rate regulator. It is connected with the venous needle; the end of the drip pot near the venous needle is set as a concave or convex liquid outlet; the drip pot is provided with a flow stop device; the flow stop device is a floating plate, and the The diameter of the floating plate is larger than the diameter of the drip pot outlet and smaller than the diameter of the drip pot; the flow stop device is connected to the positioning ring through two connecting ropes, and the positioning ring surrounds the infusion hose and can slide along the infusion hose. The end is provided with a flange, which can prevent the positioning ring from detaching from the infusion hose.

A magnet block is arranged inside the flange, and an iron sheet is arranged at a corresponding position inside the flow stop device.

The beneficial effect of adopting the above-mentioned technical scheme is: compared with the prior art, a positioning ring is provided, which avoids the problem of sideways deviation of the flow stop device when the liquid medicine is used up, and a magnet and an iron block are provided to make the flow stop device Closer contact with the infusion hose: on the one hand, it can automatically close the infusion channel to prevent air from entering the patient's body, causing an irreversible situation; on the other hand, it reduces the workload and psychological burden of medical staff to a certain extent .

detailed description

As shown in Figures 1 and 2, this solution is an empty infusion device for preventing drug droplets. The infusion device includes an intravenous needle 1, an infusion hose 2, a flow rate regulator 3 and a drip pot 4. The infusion soft The tube 2 is first connected with the infusion bottle 5 from top to bottom, and then successively connected with the drip pot 4, the flow rate regulator 3 and the venous needle 1; the drip pot 4 is provided with a flow stop device 40, specifically in this solution , the end of the drip pot 4 close to the venous needle 1 is set as a concave liquid outlet or a convex liquid outlet, and a convex liquid outlet is used in this program; in order to maximize the flow-stopping effect, the The flow stop device 40 described in this solution is a floating plate, the diameter of the floating plate is larger than the diameter of the dripping pot 4, the diameter of the liquid outlet is smaller than the diameter of the dripping pot 4, and the thickness of the floating plate in this program is 0.01mm to 0.2mm.

The flow stop device 40 is connected to the positioning ring 41 through two connecting ropes 43. The positioning ring 41 surrounds the infusion hose 2 and can slide along the infusion hose 2. The end of the infusion hose 2 is provided with a flange 21, and the flange 21 It can prevent the positioning ring 41 from detaching from the infusion hose 2 .

A magnet block 22 is provided inside the flange 21 , and an iron piece 42 is provided at a corresponding position inside the flow stop device 40 .

In specific use, when the medicinal liquid in the dripping pot 4 is more, the floating piece floats in the medicinal liquid under the effect of buoyancy, and the convex liquid outlet in the dripping pot 4 is opened, and when the medicinal liquid in the dripping pot 4 When less than the convex liquid outlet in the dripping pot 4, the floating plate closes the convex liquid outlet in the dripping pot under its own gravity, thereby preventing air from entering the infusion hose 2. When the liquid medicine is less, the floating plate moves down, and the positioning ring also moves down, because the floating plate will not be sideways due to the traction of the positioning ring. And be provided with magnet and iron block, can make stop flow device and infusion hose contact more closely.
