Description

Anti-pull-off infusion apparatus

Technical Field

The utility model relates to the technical field of medical appliances, in particular to a medical injection appliance.

Background

At present, in clinical intravenous infusion, a common infusion apparatus is used for suspending liquid in a bag (bottle) at a high position and making the liquid flow into a vein through an infusion tube under the action of gravity. The liquid leading needle is inserted into an infusion bag (bottle) and is maintained by the elasticity of rubber of a bottle stopper, and the liquid leading needle can be caused to move downwards or fall off by slight external force traction. In the process of transfusion for patients in operation, the liquid inlet needle of the transfusion device is often pulled out due to the involuntary body movement or the involuntary body movement of the patients and the transportation process, and then falls to the ground to be polluted. Nurses can only change the nursing staff, which causes the waste of medical resources and the waste of nursing manpower.

Some patients drop the infusion apparatus due to dryness, or the needle head entering the bottle slowly rebounds out due to the texture or elasticity of the rubber plug of the infusion bottle, only a small part of the needle head contacts with liquid, air and liquid enter the infusion tube discontinuously, and if accidents such as air embolism and the like are not found in time, the life of the patient is threatened, and potential safety hazards exist. If the patient is in the course of transporting, then can't change the transfusion system, need temporarily close the transfusion system, transport and accomplish the change, often because of the latency leads to the vein to keep somewhere the needle jam for a long time, need pull out and prick the needle again, not only waste but also bring the misery for the patient.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a prevent drawing and take off transfusion system to in the induced liquid needle that solves ordinary transfusion system inserts the infusion bottle, can drop because of patient's unconscious dragging or other reasons, thereby influence patient life safety, cause the trouble problem of unnecessary for medical personnel.

In order to solve the technical problem, the utility model provides an anti-drawing transfusion system that takes off, include the transfer line and be located the liquid needle that draws of transfer line front end, it includes syringe needle and needle handle to draw the liquid needle, the syringe needle overcoat has the stopper, the stopper includes left stopper and the right stopper that the shape size is identical, the diameter of stopper hole is less than the diameter of syringe needle.

Optionally, the outer wall of the limiting block is provided with anti-skid grains.

Optionally, a heparin cap is connected between the liquid introducing needle and the infusion tube.

Optionally, the connecting end of the left limiting block and the right limiting block is provided with an outer rib and an inner rib respectively.

Optionally, one end of the needle head close to the limiting block is provided with a drainage hole.

In the anti-pull-off infusion set provided by the utility model, the needle head is sleeved with the limiting block, and the outer wall of the limiting block is provided with the anti-slip lines, so that the liquid-drawing needle can be prevented from being pulled out due to unconscious pulling of a patient; the outer convex edge and the inner convex edge of the left limiting block and the right limiting block enable the limiting blocks to conveniently penetrate and sleeve the needle head, and the operability is strong; the safety of the liquid guide needle when the liquid guide needle is pulled out unintentionally is enhanced by the heparin cap between the liquid guide needle and the liquid guide needle, and the life safety of a patient is maintained to a certain extent.

Detailed Description

The following description will be made in detail with reference to the accompanying drawings and specific embodiments for an anti-pull-off infusion set of the present invention. The advantages and features of the present invention will become more fully apparent from the following description and appended claims. It should be noted that the drawings are in simplified form and are not to precise scale, and are provided for convenience and clarity in order to facilitate the description of the embodiments of the present invention.

The utility model provides an anti-pulling-off infusion apparatus, which comprises an infusion tube 1, wherein a heparin cap 4 and a liquid guiding needle 2 are sequentially connected with the infusion tube 1, the liquid guiding needle 2 comprises a needle head 20 and a needle handle 21, a limiting block 3 is sleeved outside the needle head 20, the limiting block 3 comprises a left limiting block 30 and a right limiting block 31 which are completely the same in shape and size, the connecting ends of the left limiting block 30 and the right limiting block 31 are respectively provided with an outer convex edge 300 and an inner convex edge 310, and the diameter of the inner hole of the limiting block 3 is smaller than that of the needle head 20; the outer wall of the limiting block 3 is provided with anti-skid grains 32. One end of the needle head 20 close to the limiting block 3 is provided with a drainage hole 22.

The needle head 20 is sleeved with the limiting block 3 in a penetrating manner, and the outer wall of the limiting block 3 is provided with anti-skid grains 32, so that the liquid-guiding needle 2 can be prevented from being pulled out by a patient unconsciously; the outer convex ribs 300 and the inner convex ribs 310 of the left limiting block 30 and the right limiting block 31 enable the limiting block 3 to be convenient to operate when the needle head 20 is sleeved, and the operability is high; the heparin cap 4 between the infusion tube 1 and the liquid guide needle 2 enhances the safety when the liquid guide needle 2 is pulled out unintentionally, and the life safety of a patient is maintained to a certain extent.

The utility model provides a pair of prevent drawing and take off transfusion system theory of operation as follows:

before infusion, the left limiting block 30 and the right limiting block 31 are sleeved outside the needle head 20 in a sleeved mode, the limiting block 3 is held by a hand and is inserted into a rubber plug of an infusion bottle together with the limiting block 3, the needle head 20 can be clamped by the limiting block 3 due to the fact that the diameter of an inner hole of the limiting block 3 is slightly smaller than that of the needle head 20, the limiting block 3 can be clamped by the rubber plug under the action of elasticity, the diameter of the limiting block 3 is far larger than that of a puncture hole of the rubber plug, the liquid-introducing needle 2 can be prevented from falling from the puncture hole of the rubber plug, and meanwhile, the friction force between the limiting block 3 and the puncture hole;

after infusion, the limiting block 3 is held by a hand, the limiting block 3 is completely inserted into an infusion bottle, and due to the fact that the outer convex edge 300 and the inner convex edge 310 are simply contacted, when the limiting block 3 is completely pushed into the infusion bottle, extrusion force of the rubber plug to the limiting block 3 is lost, the left limiting block 30 and the right limiting block 31 are naturally separated, and at the moment, the liquid guiding needle 2 can be pulled out.

The above description is only for the preferred embodiment of the present invention and is not intended to limit the scope of the present invention, and any modification and modification made by those skilled in the art according to the above disclosure are all within the scope of the claims.
