Abstract
The utility model discloses a nursing blood return prevention Murphy dropper comprising a pipe body. An upper part of the pipe body is provided with a liquid inlet port, and a lower part of the pipe body is provided with a liquid outlet port. A semi-circular enclosing groove and a floating ball are disposed in the pipe body. The enclosing groove, the liquid inlet port, the liquid outlet port, and the pipe body are integrated together during the production. The floating ball is disposed above the enclosing groove, and a groove hole is disposed in a middle part of the enclosing groove. The groove hole is disposed right above the liquid outlet port, and the floating ball is disposed right above the groove hole. The groove hole and the enclosing groove are integrated together during the production, and the pipe body is made of transparent plastic materials. By using the dropper provided in the utility model, when the liquid surface level is lower than the enclosing groove, the floating ball can fall under the action of the gravity, then the floating ball can stuff the enclosing groove, and can be used to enclose the groove hole in the enclosing groove, thereby the blood return can be prevented. The dropper provided in the utility model has advantages of simple structure, convenient use, safety, reliability, and abilities of preventing the blood return effectively and preventing the air from entering the patient body.
Description
Technical field:
This utility model relates to technical field of medical instruments, particularly a kind of not luxuriant and rich with fragrance dropper of nursing with blood return prevention.
Background technology:
For patient's nursing, venipuncture transfusion is one of means of using always of medical personnel, in the venous transfusion process, need use not luxuriant and rich with fragrance dropper.Be provided with inlet and liquid outlet on the body of existing not luxuriant and rich with fragrance dropper, body is cryptomere, and medicinal liquid splashes in the body along inlet, and suitable again liquid outlet and infusion pipeline, syringe needle enter in the patient.In carrying out intravenous process, when in the medicine bottle liquid output when finishing, air can get in infusion pipeline and the Mo Fei dropper, if patient or medical personnel fail discovery in time, can produce adverse consequences.As: injection inlet is at vein negative pressure section, and the air that gets in the infusion pipeline will be inhaled in the vein blood vessel, can the health of sufferer be damaged.For another example, injection inlet is at vein malleation section, when the decline of medicinal liquid liquid level reaches the pressure balance of intravenous injection porch; Liquid in the infusion pipeline does not reinject in the vein, under the diffusion between medicinal liquid and the blood, when perhaps the change of human body position causes fluctuation of blood pressure; Blood samples of patients is back in the infusion pipeline,, gets into blood in the infusion pipeline thromboembolism syringe needle that can condense as or else in time handling; Cause to continue replenishing or the injection of changing dressings; Renew liquid, can only carry out venipuncture again, cause suffering to the patient.Especially for the tiny sufferer of blood vessel, repeat inserting needle and be difficult for, run into serious symptom person, more therefore delay treatment.Therefore,, then need sufferer and medical personnel to pay close attention at any time,, avoid occurring the problems referred to above so that in time change dressings in case last medicinal liquid enters into not luxuriant and rich with fragrance dropper.Therefore and psychentonia this is with regard to the invisible labor intensity that increases medical personnel, and is prone to make the patient.
In view of above-mentioned technical problem, press for and occur a kind of simple in structurely, easy to use, safe and reliable, can effectively avoid blood to reflux, avoid air admission to the nursing of patient body not luxuriant and rich with fragrance dropper with blood return prevention.
Summary of the invention:
The purpose of this utility model is to overcome the shortcoming that exists in the prior art, provides a kind of simple in structure, easy to use, safe and reliable, can effectively avoid blood to reflux, and avoids air admission to the nursing of the patient body not luxuriant and rich with fragrance dropper with blood return prevention.
To achieve these goals, this utility model provides a kind of not luxuriant and rich with fragrance dropper of nursing with blood return prevention, comprises body; Wherein, said body top is provided with inlet, and said body bottom is provided with liquid outlet; Said body inside further is provided with enclosed slot and ball float, and said enclosed slot is semicircle shape, said enclosed slot; Said inlet, said liquid outlet and said body are one-body molded during fabrication.
Said ball float is positioned at the top of said enclosed slot; The middle part of said enclosed slot further is provided with slotted eye; Said slotted eye be positioned at said liquid outlet directly over, said ball float be positioned at said slotted eye directly over, said slotted eye and said enclosed slot are one-body molded during fabrication.
Said body is a clear plastic articles.
Be plugged and connected with transfusion catheter on the said liquid outlet; Be connected between said inlet and the medicine bottle.
After medicinal liquid got into not luxuriant and rich with fragrance dropper, ball float floated under the buoyancy of medicinal liquid, and the slotted eye on the enclosed slot is opened, and medicinal liquid flow into slotted eye, liquid outlet and then enter in patient's body through transfusion catheter.
When the medicinal liquid liquid level was lower than enclosed slot, ball float fell under action of gravity, and ball float fills up enclosed slot, and ball float is used to prevent that with getting the slotted eye sealing on the enclosed slot blood from refluxing.
The outstanding advantage of this utility model is simple in structure, easy to use, safe and reliable, can effectively avoid blood to reflux, and avoids air admission to patient body.Be specially:
After this utility model medicinal liquid got into not luxuriant and rich with fragrance dropper, ball float floated under the buoyancy of medicinal liquid, and the slotted eye on the enclosed slot is opened, and medicinal liquid flow into slotted eye, liquid outlet and then enter in patient's body through transfusion catheter.When the medicinal liquid liquid level was lower than enclosed slot, ball float fell under action of gravity, and ball float fills up enclosed slot, and ball float is used to prevent that with getting the slotted eye sealing on the enclosed slot blood from refluxing, and also avoids entering air in the transfusion catheter simultaneously, avoids the air admission human body.
