Abstract
The utility model discloses a pressurized infusion set, and belongs to the medical instrument. An air inlet pipe is provided with a check valve A, an air sac and a check valve B, wherein the check valve A and the check valve B are respectively positioned between an air inlet pipe holder and the air sac and between the air sac and an air filter assembly. The pressurized infusion set has the advantages of simple and reasonable structure, good safety, strong controllability and wide application range, is convenient and quick to operate and is especially suitable for rescuing and quickly infusing acute and serious patients.
Description
Technical field
This utility model belongs to medical apparatus and instruments, relates generally to a kind of transfusion device.
Background technology
Clinically to transfusion speed require widely differently, slowly transfusion can be accomplished with the regulation and control of the dropping speed on transfusion device assembly through existing very easily, satisfies needs of medical treatment.But, rescuing serious symptom anxious troubles needs when realizing transfusion fast, the patient who especially infuses with plain edition number sword-shaped needle; It is just difficult more to accomplish quick transfusion; Changing the large size scalp acupuncture not only can increase less patient suffering, and can increase the weight of the destruction to blood vessel, has strengthened the difficulty of nurse's puncture.At this moment, or the medicinal liquid bottle improved height and position increasing the medicinal liquid downstream pressure as far as possible, or constantly push Murphy type tube with hands by the nursing staff, increase medicinal liquid pressure, above-mentioned two kinds of ways are to accelerating medicinal liquid speed effect and not obvious, and operation inconvenience.
Summary of the invention
The purpose of this utility model is exactly the problem that exists to above-mentioned prior art, and according to the actual needs of clinical treatment, design provides a kind of adding pressure type transfusion device, reach adapt to and satisfy needs of medical treatment, improve therapeutic effect, purpose that handled easily uses.
The basic design of this utility model is; The adding pressure type transfusion device comprises transfusion seat, air inlet base, air inlet pipe, air filtration assembly, syringe needle, liquid medicine filter, dropping speed regulation and control assembly, tube for transfusion and Murphy type tube; Equipped check valve A, air bag and check valve B on air inlet pipe; Check valve A position between air inlet base and air bag wherein, check valve B is the position between air bag and air filtration assembly.
This utility model both can be used as the adding pressure type transfusion device and had used; Can be used as conventional general infusion set again uses; Have simple in structure, pressurized operation is convenient and swift, safety good, controllability is strong, the characteristics of applied range; Especially satisfy anxious heavy patient and rescued quick transfusion use, improved therapeutic quality.

Accompanying drawing is the overall assembly structure sketch map of adding pressure type transfusion device.
Piece number explanation among the figure:
1, tube for transfusion, 2, air inlet base, 3, check valve A, 4, air bag, 5, check valve B, 6, air inlet pipe, 7, air filtration assembly, 8, syringe needle, 9, liquid medicine filter, 10, dropping speed regulation and control assembly, 11, tube for transfusion, 12, Murphy type tube.
The specific embodiment
Below in conjunction with accompanying drawing this utility model optimum implementation is described in detail.The adding pressure type transfusion device comprises transfusion seat 1, air inlet base 2, air inlet pipe 6, air filtration assembly 7, syringe needle 8, liquid medicine filter 9, dropping speed regulation and control assembly 10, tube for transfusion 11 and Murphy type tube 12; Equipped check valve A 3, air bag 4 and check valve B5 on air inlet pipe 6; Check valve A3 position between air inlet base 2 and air bag 4 wherein, check valve B5 is the position between air bag 4 and air filtration assembly 7.
During use, operate with the traditional exhaust method.Need not pressurize when using with the common transfusion pipe, check valve A3, check valve B5 on the air inlet pipe 6 all are in the unlatching aeration status, keep the medicinal liquid pressure of the inside of a bottle to equate with atmospheric pressure; When the need pressure transfusion, with hands extruding gasbag 4, pressed gas charges in the medicinal liquid bottle from check valve A 3; Simultaneous pressure gas is closed check valve B5; Pressed gas can not be leaked in the atmosphere, unclamp air bag 4, the air in the negative pressure official post atmosphere in the air bag 4 is opened check valve B5 through air filtration assembly 7 and is got in the air bag 4; Negative pressure is closed check valve A3 synchronously; Avoid the pressed gas in the medicinal liquid bottle to return in the air bag 4, continuously extruded repeatedly air bag 4 is promptly accomplished the pressurization in the infusion bottle, realizes the medical requirement of transfusion fast.The size of pressurization is directly proportional with the extruding number of times of air bag 4, and the transfusion speed that requires according to doctor's advice decides.Infusion speed is to break through the fast supplied materials that drips of observing Murphy type tube 12.
