Intermittent transfusion set

Abstract

The invention discloses an intermittent transfusion set, which comprises an air inlet tube air filter, a bottle plug puncture unit, a drip cup and an injection needle head, and is characterized in that: the drip cup has a Y-shaped three-way structure, and is provided with two branch tubes to which two transfusion paths are connected; a one-way valve is arranged in the branch tube on a left side; under the action of the one-way valve, a liquid is only allowed to flow downwards; a saline water bottle is connected to the branch tube on the left side; and a medicament bottle is connected to a branch tube on a right side. The intermittent transfusion set has the advantages: when multiple bottles of liquids are required to be transfused continuously for a patient, saline water on the left side can be transfused continually if the medicament bottle replacing time is intermittent or delay, so that the phenomena of blood return and the introduction of excessive air into a transfusion pipeline are avoided; medical personnel can nurse a plurality of patients receiving transfusion simultaneously, so that the quantity of nursing personnel can be reduced; and a secondary transfusion path can play a role in eroding a primary transfusion path after dripping of the main transfusion path, so that pharmacological reactions among different medicaments are avoided. The intermittent transfusion set can be applied to one-time transfusion for various types of patients on medical treatment.

Description

technical field [0001] The invention relates to a medical appliance, in particular to a disposable infusion set. Background technique [0002] A large number of disposable infusion sets are used in hospitals every day. The current disposable infusion sets include intake air filters, cork puncturers, drip pots and injection needles. The suit is equipped with a flow regulator. When the patient needs to infuse multiple bottles of liquid at a time using this conventional infusion set, the next bottle must be changed after each bottle is infused. For a moment, if the medicine solution is changed early and the drip is not finished, there will be waste. If the change is late, a lot of air will enter the infusion line, and even blood will return. After the air enters the line, the bottle must be exhausted, which is troublesome. .

Problems solved by technology

[0002] A large number of disposable infusion sets are used in hospitals every day. The current disposable infusion sets include intake air filters, cork puncturers, drip pots and injection needles. The suit is equipped with a flow regulator. When a patient needs to infuse multiple bottles of liquid at a time using this conventional infusion set, the next bottle must be replaced after each infusion. For a moment, if the medicine solution is changed early and the drip is not finished, there will be waste. If the change is late, a lot of air will enter the infusion line, and even blood will return. After the air enters the line, the bottle must be exhausted, which is troublesome.

Because there are often a lot of patients with infusion in each hospital, it is difficult to allow the limited medical staff to arrive at the short moment when the medicine is dripped every time. Therefore, the use of this conventional infusion set often causes liquid Waste, pipeline air intake, blood return, etc.
