Abstract

The utility model discloses an anti-fall transfusion apparatus and belongs to a blood transfusion device. A tail end of a lower section transfusion pipe of the transfusion apparatus is inserted with one end of a circular insert pipe. A concentric and isodiametric pipe on the other end of the circular insert pipe is provided with a concentric internally threaded sleeve outside. The bottom of the internally threaded sleeve is fixedly connected with a wall circular insert pipe. An opening of the internally threaded sleeved is open. By use of the protruding points at two sides of a pintle, the pintle of a retaining needle can be screwed into the internally threaded sleeve of the insert pipe of the transfusion apparatus, and one end of the concentric pipe inside the internally threaded pipe still extends into the pintle, so the insert pipe is firmly connected with the pintle and insusceptible to falling off. The anti-fall transfusion apparatus can prevent large loss of blood and avoid failures in transfusion of medicines for rescue into the body and consequently delayed rescues caused by the fall of the insert pipe. The anti-fall transfusion apparatus is particularly suitable for patients in light coma or dysphoria to reduce the workload of medical personnel.

Description

Slip-off preventing blood exchange transfusion set

Technical field

This utility model relates to the device of pumping blood, is a kind of slip-off preventing blood exchange transfusion set specifically.

Background technology

The blood exchange transfusion set is an indispensable special implement during medical treatment is rescued.At present, the connected mode of clinical blood exchange transfusion set's venous detaining needle commonly used is the grafting of simple circular cone interface and plug, and this connected mode often causes the two and comes off.Especially under surgical drage covers, be difficult to find that interface comes off, and in case find that patient has lost a large amount of blood; Or salvage drug fails to inject in the patient body, delays rescue opportunity.Also see light coma patient or restless patient, interface is come off, increase medical personnel's workload.

Summary of the invention

Technical problem to be solved in the utility model is to connect venous detaining needle and the slip-off preventing blood exchange transfusion set of difficult drop-off in order to provide a kind of.

The technical scheme that this utility model adopted is: slip-off preventing blood exchange transfusion set comprises elongated needle that thrusts infusion bottle and epimere blood transfusion tube, Murphy tube, the hypomere blood transfusion tube that is communicated with down thereof, and add the water of regulating flow in the hypomere blood transfusion tube and end, it is characterized in that terminal one one end of pegging graft of hypomere blood transfusion tube is the circle intubate, the concentric inner screw sheath of concentric isometrical pipe peripheral hardware of the other end, affixed with the circle cannula wall at the bottom of the inner screw sheath, inner screw sheath top mouth is open.

The beneficial effects of the utility model: this utility model has changed transfusion device circular cone intubate and has inserted the interior mode of remaining needle pintle, utilize remaining needle pintle both sides salient point, in the inner screw sheath with it screw-in transfusion device intubate that is spirally connected, and the concentric circular intubate still stretches in the pintle in the thread bush, be spirally connected firmly difficult drop-off like this.

Description of drawings

Accompanying drawing is this utility model syndeton schematic appearance.

1 elongated needle, 2 epimere blood transfusion tubes, 3 Murphy tubes, 4 hypomere blood transfusion tubes, 5 water end, 6 circle intubate, 7 inner screw sheaths, 8 remaining needles, 9 pintle salient points.

The specific embodiment

Slip-off preventing blood exchange transfusion set comprises elongated needle 1 that thrusts infusion bottle and epimere blood transfusion tube 2, Murphy tube 3, the hypomere blood transfusion tube 4 that is communicated with down thereof, and add the water of regulating flow in hypomere blood transfusion tube 4 and end 5, it is characterized in that hypomere blood transfusion tube 4 terminal one one ends of pegging graft are slotting 6 pipes of circle, the concentric inner screw sheath 7 of concentric isometrical pipe peripheral hardware of the other end, 7 ends of inner screw sheath, are affixed with circle intubate 6 walls, and female thread 7 cover top mouths are open.The inner screw sheath outer wall is 6-8 prisms of being convenient to grip like this.Inner screw sheath is cylindrical, and perisporium has rag, is convenient to grip turn.Establish the leaflet support to reinforce it along its major axis at the bottom of the inner screw sheath.Respectively there is the pintle salient point 9 of a correspondence commercially available remaining needle 8 pintle both sides, and just firmly peg graft with the puncture pintle trigger piece of remaining needle 8, prevent to rotate.The tight threaded of salient point of She Ji inner screw sheath and remaining needle pintle both sides like this.

Claims (1)

1, slip-off preventing blood exchange transfusion set, comprise elongated needle (1) that thrusts infusion bottle and epimere blood transfusion tube (2), Murphy tube (3), the hypomere blood transfusion tube (4) that is communicated with down thereof, and add the water of regulating flow in hypomere blood transfusion tube (4) and end (5), it is characterized in that terminal one one end of pegging graft of hypomere blood transfusion tube (4) is circle slotting (6) pipe, the concentric inner screw sheath of concentric isometrical pipe peripheral hardware (7) of the other end, inner screw sheath (7) end, is affixed with circle intubate (6) wall, and female thread (7) cover top mouth is open.
