Abstract
The utility model discloses a negative pressure transfusion system which is provided with a perfusion tube. The perfusion tube is connected in series with two adjustors, and each adjustor is provided with a pulley which can slide along the inner wall of the adjustor. The negative pressure transfusion system solves the puncture problem of a nurse for a patient with bigger puncture trouble, and for the patient with better angioplerosis, the puncture can be successful without the bending of a tourniquet. The negative pressure transfusion system has the advantages of simple structure, safety and reliability.
Description
Technical field
This utility model relates to technical field of medical instruments, specifically, is a kind of negative-pressure type transfusion device.
Background technology
At present, known transfusion device is the device that has an actuator, and it has control and adjusts the function of dripping speed.But the nurse is in piercing process, because the effect of fluid pressure and gravity, or blood is full, makes blood back not smooth, even experienced nurse often sticked a needle into deeply because of loseing blood back, blood back is seen by withdraw of the needle time side, causes puncture failure.Repeated localised puncture makes the patient suffering, incurs loss through delay patient's therapeutic time, has reduced medical personnel's work efficiency, influences nurse-patient relationship, influences patient and family members' emotion.And, also have influence on the normal order of work of medical institutions easily because puncture failure needs to change the cost issues that needle tubing brought.
The utility model content
This utility model has overcome above-mentioned shortcoming, has proposed a kind of negative-pressure type transfusion device.
The technical scheme in the invention for solving the technical problem is:
A kind of negative-pressure type transfusion device is provided with a tube for transfusion, and tube for transfusion is serially connected with two actuators, and being provided with in each actuator can be along the pulley of actuator inwall slip.
By controlling the slip of two pulleys, can make and form one section constant and persistent negative pressure, the success that this helps puncturing in the tube for transfusion.Therefore this utility model also is called " negative-pressure type transfusion device ".
Advantage of the present utility model is: this utility model has solved the puncture problem of nurse to the big patient of venipuncture difficulty, to angioplerosis patient preferably, can prick tourniquet and just can puncture successfully.This utility model also has simple in structure, safe and reliable characteristics.

The specific embodiment
Embodiment 1
As shown in Figures 1 to 4, negative-pressure type transfusion device described in the utility model is provided with a tube for transfusion 1, and tube for transfusion is serially connected with two actuators, i.e. adjusted device 2 and following actuator 3; Being provided with in each actuator can be along the pulley of actuator inwall slip, i.e. top sheave 4 and lower sheave 5.
As shown in Figure 1, open adjusted device 2 and following actuator 3, top sheave 4 and lower sheave 5 roll to the upper end of tube for transfusion 1, drain the air in the tube for transfusion 1.
As shown in Figure 2, close adjusted device 2, top sheave 4 rolls to tube for transfusion 1 lower end, makes top sheave 4 be in closed condition, and lower sheave 5 still is in open state.
As shown in Figure 3, close down actuator 3, lower sheave 5 rolls to tube for transfusion 1 lower end, forms negative pressure between top sheave 4 and lower sheave 5.
As shown in Figure 4, treat syringe needle 6 inclined-planes enter fully subcutaneous after, open actuator 3 down, lower sheave 5 rolls to tube for transfusion 1 upper end, negative pressure maintains top sheave 4 with the lower end.
As mentioned above, make transfusion device form one section constant and persistent negative pressure after adjusting the up-down adjustment device, this negative pressure helps the nursing staff at the subcutaneous searching vein blood vessel of patient.Under the assistance of negative pressure " suction ", blood back obviously and rapidly, the blood back amount strengthens, and the puncture accuracy rate improves greatly.
More than negative-pressure type transfusion device provided by the utility model is described in detail, used specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present utility model and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present utility model, part in specific embodiments and applications all can change.In sum, this description should not be construed as restriction of the present utility model.
