Abstract
A closed aseptic puncture outfit, which comprises a needle socket, a needle fixed in the needle socket. A needle cap sleeve made of latex and silicone rubber is disposed at the front top of the needle, protection sleeve is provide with two-layer structure making up of an internal casing and an external casing, the nozzle of the internal casing is stick to the needle socket, wherein a depression thin walled cycle is provide at the top of the nozzle to connect the casing body. The internal casing and the external casing are intercalated together through two symmetric longitudinal grooves arranged at the inner wall of the external casing and two symmetric longitudinal convex ribs arranged at the outside wall of the internal casing, and the inner wall of the external casing nozzle combined closely with the outside wall of the internal casing nozzle sticking to the needle socket. In course of using the utility model, the needle can not be exposed in the air, therefore preventing contaminant from bacteria; after use the present model, the two-layer structure protection sleeve can still sleeve the needle socket so as to cover the needle, preventing the risk that needle tip hurts operator's hand.
Description
Technical field:
This utility model relates to the perforator in a kind of plastics blood transfusion equipment, especially blood exchange transfusion set, blood and blood constituent inactivation of virus equipment and the leucocyte-removing filter.
Background technology:
Existing perforator, its front end has protective sleeve.Protective sleeve is that machinery cooperates with the needle stand that is fixed with pin, is not fully airtight.The aseptic effectiveness of therefore a whole set of plastics blood transfusion equipment must rely on the tightness of packaging bag to guarantee; Secondly when needs imports blood and blood constituent blood exchange transfusion set or input blood and blood constituent inactivation of virus equipment and are carried out blood and blood constituent inactivation of virus or import the leucocyte-removing filter carrying out the leucocyte-removing processing from the blood bag; to use needle-penetration blood bag blood transfusion socket; in this process; earlier protective sleeve is extracted from needle stand; this section that inserts blood bag blood transfusion socket again to pin this moment in the period pin be exposed aerial; be subject to germ contamination (especially blood and the blood constituent after the input also will be preserved one period date, so the bacterial reproduction potential hazard is bigger).After using end, the perforator pin is extracted from the blood bag, because protective sleeve has twisted off with needle stand and separated, can not needle stand be entangled again, and the pin on the needle stand is easily hindered operator's handwritten visiting card.
Summary of the invention:
In order to overcome the deficiency that existing perforator in use exists, this utility model provides a kind of closed aseptic perforator, both can make the airtight maintenance of a whole set of plastics blood transfusion equipment aseptic condition itself, can in use significantly reduce the exposed aerial time of pin again and reduce exposed area, make blood and blood constituent not be subject to germ contamination; Use and finish, protective sleeve still can be enclosed within on the needle stand, makes pin can not stab operator's hands.
The aseptic perforator of the closed that this utility model provides; comprise needle stand; be fixed in the pin on the needle stand; be enclosed within the protective sleeve on the needle stand; the front end of pin is provided with the pin medicated cap that latex or silicone rubber are made; protective sleeve has inner sleeve and trocar sheath double-decker; the mouth of pipe inwall and the needle stand of inner sleeve are bonding; mouth of pipe top is provided with depression thin-walled circle and connects pipe shaft; the inner sleeve outer wall is provided with two symmetric vertical convex tendons; outer sleeve inner wall is provided with two symmetric longitudinal flutings; trocar sheath and inner sleeve be by the fit of groove and convex tendon, trocar sheath mouth of pipe inwall and the tight fit of inner sleeve mouth of pipe outer wall that is bonded on the needle stand.
In order when using this utility model, to rotate protective sleeve easily, the depression thin-walled circle of inner sleeve is twisted into two parts and needle stand is separated with protective sleeve, in the both sides of needle stand the needle stand wing is set, be more convenient for gripping and can adding high pulling torque.
The beneficial effects of the utility model are: the pin that will be fixed on the needle stand during use is extracted protective sleeve; this moment is owing to the front end position that has latex or silicone rubber pin cap sleeve at pin; pin does not expose in air; insert blood bag blood transfusion socket and part with the inner ring of blood transfusion socket when chimeric at pin, firmly make needle point puncture the pin medicated cap, thrust in the blood transfusion socket barrier film and be communicated with again with bag inner blood and blood constituent.Pin and air are in isolation in this process, thereby are not subjected to germ contamination.In addition, because protective sleeve has inner sleeve, trocar sheath double-decker, twist off the depression thin-walled of inner sleeve, extract protective sleeve, this moment, the mouth of pipe of inner sleeve still was bonded on the needle stand.After using end, the trocar sheath mouth of pipe of protective sleeve still can be enclosed within on the outer wall of the inner sleeve mouth of pipe that is bonded on the needle stand, and needle guard is lived, and needle point can not stabbed operator's hands.
Description of drawings:
Fig. 1 is a sketch map of the present utility model.
In Fig. 1,1. inner sleeve, 2. trocar sheath, 3. pin medicated cap, 4. pin, the 5. depression thin-walled circle of inner sleeve, the 6. inner sleeve mouth of pipe, the 7. trocar sheath mouth of pipe, 8. needle stand, the 9. needle stand wing, the 10. groove of trocar sheath, the convex tendon of .11. inner sleeve.
The specific embodiment:
In Fig. 1, pin (4) is bonded in both sides to be had on the needle stand (8) of the needle stand wing (9), the pin medicated cap (3) that latex or silicone rubber are made on the front end sleeve of pin (4), the inner sleeve (1) that will have a depression thin-walled circle and trocar sheath (2) behind the fit, are bonded in the inwall of the inner sleeve mouth of pipe (6) on the needle stand (8) in advance.Only need twist off the depression thin-walled circle (5) of the inner sleeve mouth of pipe (6) top when using this utility model, extract inner sleeve (1) and trocar sheath (2), the inner sleeve mouth of pipe (6) still is bonded on the needle stand (8), after using end, the trocar sheath mouth of pipe (7) can be enclosed within on the outer wall of the inner sleeve mouth of pipe (6) again, and needle point is not exposed.
Claims (2)
1. aseptic perforator of closed; comprise needle stand; be fixed in the pin on the needle stand; be enclosed within the protective sleeve on the needle stand; the front end that it is characterized in that pin is provided with the pin medicated cap that latex or silicone rubber are made; protective sleeve has inner sleeve and trocar sheath double-decker; the mouth of pipe inwall and the needle stand of inner sleeve are bonding; mouth of pipe top is provided with depression thin-walled circle and connects pipe shaft; the inner sleeve outer wall is provided with two symmetric vertical convex tendons; outer sleeve inner wall is provided with two symmetric longitudinal flutings; trocar sheath and inner sleeve be by the fit of groove and convex tendon, trocar sheath mouth of pipe inwall and the tight fit of inner sleeve outer wall that is bonded on the needle stand.
