Abstract
The utility model relates to a medical instrument, and concretely relates to a novel safe arteriovenous puncture needle for hemodialysis. A safe protector is made from medical grade PP through injection moulding and is disposed on a catheter behind fins of the arteriovenous puncture needle, and a figure loop is disposed on one end of the safe protector and is ring-shaped. After the arteriovenous puncture needle is used and before the needle is retreated, a user put his/her figure into the loop, presses the protector down to the absorbent cotton for fixation and pulls the catheter to make the double fins and the needle tip into the safe protector which is internally provided with a locking sheet.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, be specifically related to a kind of new type of safe hemodialysis diacan with the safeguard protection effect.
Background technology
Hemodialysis is medical procedure the most frequently used in the Hospital medical, for treatments such as renal failure, acute pancreatitis, strong hepatitis, postoperative liver decline.Behind the hemodialysis artery and vein puncture, when medical personnel dialysed for the patient, the most basic requirement was safe puncture.Only have patient safety, medical personnel's safety, these three aspects of Environmental security are possessed simultaneously, just be referred to as safe puncture.Raising along with clinical medicine level understanding, promote the use of disposable apparatus from preventing cross infection, arrive again since to progressively in-depth, the especially acquired immune deficiency syndrome (AIDS) of blood borne disease understanding the spreading unchecked of the whole world, thereby security classes product that the medical personnel that are engaged in the excessive risk occupation are protected appears; And for preventing the harm that Biohazard Waste causes environment; force the waste recovery box of use; etc.; embodiment is paid attention to all personnel's (comprising patient, user, recycling personnel etc.) that protection contacts with apparatus simultaneously from forbidding merely reusing, and this is a kind of progress of medical development.
Also very serious to the damage that medical personnel cause to dangerous puncture, according to statistics, annual 1000000 medical workers are subject to the syringe needle injury, wherein 84.6% is the nurse, therefore some also catch the haematogenous infectious disease such as hepatitis and acquired immune deficiency syndrome (AIDS), the nurse of investigation discovery 87.9% had the experience of injury from sharp utensil, and pricking wound occured the nurse more than 80%.
The disposable product that generally uses both at home and abroad at present, how from preventing that patient's cross infection from starting with, but according to WHO about safety injection to patient safety, to medical personnel safety, environmentally safe three principles, existing disposable product can not satisfy the principle of safe handling.
The utility model content
The purpose of this utility model provide a kind of cost low, can be to the needle point behind the hemodialysis artery and vein puncture, the new type of safe hemodialysis diacan of protecting.Protector provided by the present invention is injection molded, simple in structure, easy to operate with the PP of medical grade.
The technical solution of the utility model; wear at existing disposable artery and vein puncture wire guide and to add a protector; protector before use; be freely be through supravasal; it is that a end at protector is the circle shape that described finger ring is buckled; after venipuncture is complete; before puncture needle withdraws from; finger buckles into and presses to absorbent cotton and fixes, and then spurs conduit, has in the double-vane needle point enters smoothly in the protector that ends strike plate; unlikely needle point with blood exposes; both protect patient's use safety, and also made medical personnel and discarded needle point recovery personnel avoid the danger of needle sting, avoided the generation of cross infection.
New type of safe hemodialysis diacan provided by the utility model, by the double-vane diacan, the artery and vein puncture wire guide, protector, water ends, and catheter adapter forms.
The beneficial effects of the utility model are:
1, can carry out safeguard protection to needle point behind the artery and vein puncture, meet WHO about the principle of safety injection, effectively protect patient safety, medical personnel's safety and Environmental security;
2, product operation is convenient, avoids cross infection, is beneficial to clinical expansion and uses;
Description of drawings
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing thereof.
Fig. 1 is new type of safe hemodialysis diacan structural representation of the present invention.
The same Fig. 1 of Fig. 2, but show the protected state of needle point.
Fig. 3 is the sketch map of the protector among Fig. 1.
Among the figure, 1 double-vane diacan, 2 artery and vein puncture wire guides, 3 protectors, 4 water end, 5 catheter adapters.
The specific embodiment
The structure of new type of safe hemodialysis diacan provided by the utility model as shown in Figure 1 to Figure 3; illustrate that in conjunction with Fig. 11 diacan is connected with 2 artery and vein puncture wire guides, penetrates 3 protectors in the conduit; conduit penetrates 4 water to be ended, and catheter tail connects 5 catheter adapters.
Protector 3 in this utility model is after normal puncture, uses when needle point need to withdraw from.Concrete operations are that in the needle point the place ahead of puncturing, hand-held conduit slowly before is pushed into circle shape handle to protector with multilamellar defat cotton yarn pad, place in the middle of the defat cotton yarn.Catch on circle shape handle with hands and depress cotton yarn this moment, and cotton yarn is attached on the skin, pushes down the pinprick place, and it does not highly hit puncture needle, and then light pull catheter is extracted diacan, is pulled to the holddown groove place.Only strike plate is arranged in the groove, needle point can not be withdrawed from voluntarily.New type of safe hemodialysis diacan; when the complete puncture needle that punctures is extracted in the body; protector is drawn in needle point in the protector; puncture needle is protected; and then marketing is ruined; can effectively protect medical personnel not stab, be not infected with blood, reach patient safety, medical personnel's safety and Environmental security.
The protector of new type of safe hemodialysis diacan is characterized in that: a kind of new type of safe hemodialysis diacan, protector wherein, finger ring are buckled and can be made the open style of semicircle.
The protector of new type of safe hemodialysis diacan is characterized in that: described only strike plate is flat-shaped.
New type of safe hemodialysis diacan is characterized in that: described protector is injection molded with the PP of medical grade.
New type of safe hemodialysis diacan is characterized in that: described new type of safe hemodialysis diacan, protector can also be made split type.
Among the present invention, processing technology is simple, and cost is low, and is easy to use, can protect well medical personnel and recycling personnel not by acupuncture, avoids cross infection.An environmental protection, healthy!
