Abstract
The utility model discloses an infusion apparatus capable of generating negative pressure, which is formed through improving based on a common infusion apparatus, wherein a fixer (3) is arranged between a dropping speed adjuster (1) and a filter screen (2) of an original infusion apparatus, and the fixer (3) is used to be fixed on an infusion pipe which is reflexed during the piercing process. The infusion apparatus can increase the success rate of piercing through the negative pressure which is formed during the piercing process, guarantees rescue and treatment to be smooth, protects vascular, reduces pain, and increases self-confidence of nurses.
Description
Technical field
This utility model relates to a kind of transfusion device.
Background technology
Venous transfusion is that the patient receives treatment, the important channel of rescue, intravenous nutrition, in clinical position, often run into some massive blood losses mistake liquid and cause end poor circulation slightly, not full and full obese patient and the thinner infant of scalp blood capillary of subcutaneous fat of vein, this type of patient is often not full because of vein, the depth is difficult for grasping, in piercing process, blood back causes puncture failure because of being difficult for immediately, incur loss through delay and rescue and treatment time, and destroy blood vessel, increase the patient suffering, simultaneously, increase nurses ' psychology pressure.
Summary of the invention
The purpose of this utility model is that a kind of infusion set that can produce negative pressure will be provided, and it not only can increase the success rate of puncture, and for opportunity is won in rescue, the protection blood vessel alleviates patient's misery, simultaneously, increases nurse's self-confidence.
For achieving the above object, the technical solution adopted in the utility model is as follows:
It is to change a social system to form on the basis of general infusion set, promptly dripping of original transfusion device a holder is installed between fast actuator and the drainage screen, and this holder is in order to be fixed on the tube for transfusion of opisthotonos in the piercing process.
The beneficial effects of the utility model are: utilize the negative pressure that forms in the piercing process, improve the success rate of puncture, guarantee to rescue and treat and carry out smoothly, the protection blood vessel palliates the agonizing sufferings, and increases nurse's self-confidence.
Description of drawings
Fig. 1 is the transfusion device structural representation that can produce negative pressure.
The specific embodiment
Below in conjunction with drawings and Examples this utility model is further specified.
The transfusion device that can produce negative pressure is on a fast actuator 1 of general infusion set and the tube for transfusion between the drainage screen 2 holder 3 to be installed, and holder 3 is in order to be fixed on the tube for transfusion of opisthotonos in the piercing process.
When carrying out venous transfusion, conventional air of discharging in the transfusion device, close and drip fast actuator 1, will apart from the tube for transfusion at 10cm place, drainage screen 2 upper end with " Z " font opisthotonos 5cm about, and folded part is put in the holder fixed, puncture routinely then, when the scalp acupuncture inclined-plane thrusts Intradermal fully, to push away on the holder 3, unclamp burst, at this moment, produced negative pressure in the transfusion device, the intraluminal pressure of scalp acupuncture is starkly lower than vein pressure, then, move towards to continue puncture along vein, at this moment, enter intravenous as syringe needle, then can produce blood back immediately because of intravenous pressure is higher than the intraluminal pressure of scalp acupuncture, see behind the blood back again inserting needle a little, confirm that syringe needle is in blood vessel, open and drip fast actuator 1 conventional fixing, infuse.
Claims (1)
1. can produce the transfusion device of negative pressure, it is to change a social system to form on the basis of general infusion set, it is characterized in that: be provided with a holder (3) dripping between fast actuator (1) and the drainage screen (2) of original transfusion device, this holder (3) is in order to be fixed on the tube for transfusion of opisthotonos in the piercing process.
