Problems solved by technology

[0004] As we all know, my country has promoted the use of ordinary disposable infusion sets since the 1980s, and has a history of more than 30 years. It has played a positive role in preventing cross-infection in clinical infusions; There are certain shortcomings: when the infusion is completed or the infusion group is alternated, the air is easy to enter the infusion hose. If the treatment is not timely, the air input into the human body will have an impact on the patient's health; it also increases the care of the medical staff. The intensity of work can easily lead to doctor-patient disputes; therefore people expect to have a safer and more effective product, so that the majority of medical staff and patients can use it safely and safely; in order to solve the above-mentioned technical problems, some existing technologies such Technical solutions such as:

Embodiment 2

[0046] In order to realize the function of fitting and installing the fixed column core 3-4-1 and the sealing diaphragm 3-4-2, the present invention is provided with a card slot 3-4-3 and a fixed limit hole 3-4-2-3; the floating body 3 The lower part of -4 is a fixed column core 3-4-1; the sealing diaphragm 3-4-2 is provided with a fixed limit hole 3-4-2-3; the sealing diaphragm 3-4-2 passes through the fixed limit hole 3 -4-2-3 passes through the fixed column core 3-4-1 and is fixed at the slot 3-4-3.

[0047] The fixed column core 3-4-1 of the present invention refers to: the bottom of the floating body 3-4; its function is to fix the column core (3-4-1) diameter and liquid outlet (3-3-2) phase airtight Cooperate, as the liquid level of the liquid medicine drops, it cooperates with the inner side of the liquid outlet, and is fixedly guided on the inner side of the liquid outlet 3-3-2, forming a sealing surface with the liquid outlet to realize the sealing effect of the float...

Embodiment 3

[0050] In order to realize the installation limit function of the sealing diaphragm 3-4-2 in the present invention, the sealing diaphragm 3-4-2 is designed as a reinforcement ring 3-4-2-1 and a liquid stop membrane surface 3-4-2-2 1. Three parts of fixed limit hole 3-4-2-3; reinforcement ring 3-4-2-1 and liquid stop membrane surface 3-4-2-2 can be set separately or integrally formed; sealing diaphragm For the reinforcement ring 3-4-2-1 is on the top, and the liquid stop membrane surface 3-4-2-2 is installed in a convex shape below.

[0051] The sealing diaphragm 3-4-2 of the present invention refers to: the device that realizes the sealing effect at the lower part of the floating body 3-4; it is provided with a reinforcing ring 3-4-2-1 and a liquid-stopping membrane surface 3-4-2 -2. Fix the limit hole 3-4-2-3; its function is to cooperate with the liquid outlet 3-3-2 to form a sealing structure; its structure is as attached Figure 9 As shown, its cross-sectional structure i...

Abstract

The invention relates to a disposable self-sealed automatic liquid-stopping transfusion device comprising a bottle plug piercing device, a dropper, a dripping chamber, a hose, a flow adjuster, a medicine liquid filter, a connector and a vein transfusion needle. A safety mechanism is formed by a spacing member disposed in a dripping chamber body and a floating body arranged between the spacing member and a liquid outlet, wherein the floating body is provided with a fixed column core, a sealing membrane, a neck and a liquid passing groove; the diameter of the fixed column core is in sealed cooperation with the liquid outlet; the fixed column core is fixedly guided on the inner side of the liquid outlet with decrease of a medicine liquid level; the sealing membrane and the liquid outlet form a sealing surface; when medicine liquid is almost finished, the floating body sinks and blocks the liquid outlet of the transfusion device with the decrease of the liquid level of the transfusion device, so stopping effect of medicine liquid can be achieved. The disposable self-sealed automatic liquid-stopping transfusion device is rationally designed and simply structured and easy to manufacture; the device can be widely applied to present transfusion devices; and with a safety protection function added to the transfusion device, safe transfusion can be achieved.
