Description
Technical Field
The utility model aims at providing a fitting of a safe transfusion needle, in particular to a sleeve of the safe transfusion needle, belonging to the technical field of medical appliances.
Background
In clinical work, the occurrence of needle stick injuries related to injection is random and uncontrollable, and nursing staff are high-risk groups of needle stick injuries. Social hazards from unsafe injections include pricking others with a needle after use and the social spread of infection caused by improper handling of the injection device after use. Standard prevention was proposed by the American disease control center in 1995, implemented in the United states in 1996 throughout the United states, introduced in 1999 in China and introduced in 2000 in the Hospital infection management code (trial) issued by the Ministry of health. The standard prevention view is that: all patients have infectious blood, body fluids, excretions, secretions, whether or not there is significant contamination of blood stains or contact with non-intact skin mucosa, which requires isolation. Therefore, the large amount of use of the disposable transfusion needle brings about the problem of safe disposal of the disposable transfusion needle.
The safe transfusion needle that uses usually at present, including transfer line and pjncture needle, pjncture needle and transfer line junction are provided with the transfusion needle fin, and the cover is equipped with safety kit on the transfer line, and safety kit holds between the fingers the handle by the sleeve pipe that can accept the pjncture needle and sleeve pipe and constitutes, sleeve pipe one side be provided with transfusion needle fin complex spout, the spout extends to holding between the fingers handle department by the sleeve pipe tip. After the transfusion of the safe transfusion needle is finished, the pinch handle is held by one hand, the transfusion needle wing piece is held by the other hand, the pinch handle and the transfusion needle wing piece move relatively, and the transfusion needle wing piece slides into the sliding groove. The sliding groove is provided with a limiting protrusion, so that the puncture needle is kept in the sleeve, and the safety protection effect is achieved.
However, the end of the cannula is wedge-shaped and the end is sharp, so this safety-assurance cannula is not reasonable in design, for example, when giving a transfusion to a small child who prefers to move around, the cannula may scratch or puncture the skin.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a sleeve of a safe transfusion needle to solve the problems in the prior art.
The purpose of the utility model can be realized through the following technical scheme:
a sleeve of a safe transfusion needle comprises a puncture needle and a safe sleeve for accommodating the puncture needle, wherein a transfusion needle wing panel is arranged at the joint of the puncture needle and a transfusion tube; a sliding groove matched with a transfusion needle wing panel is arranged on the side wall of the safety sleeve; one or more limiting protrusions are arranged on the sliding groove; the root of the safety sleeve is a sleeve handle, and the end part of the safety sleeve is a limiting wedge-shaped surface; and the edge of the end part of the limiting wedge-shaped surface is provided with a smooth chamfer edge.
The edge of the end part of the limiting wedge-shaped surface is turned outwards to form a smooth chamfered edge.
The sleeve pinching handle is provided with a limiting groove, the limiting groove is communicated with the sliding groove, and the length from the sleeve pinching handle to the nearest limiting protrusion is smaller than the height of the transfusion needle wing.
In order to facilitate pushing the wing of the transfusion needle into the limiting groove, the end part of the sleeve is designed into a limiting wedge-shaped surface, and the lowest point of the limiting wedge-shaped surface is an inlet part of the sliding groove.
The number of the limiting bulges is three.
The preferred embodiment is that the height of the limiting groove is equal to the height of a wing piece of the transfusion needle, and the limiting projection closest to the sleeve handle is arranged at the joint of the sleeve and the sleeve handle.
The sliding grooves are not on the same straight line, and more preferably, one section of each sliding groove is in an arc shape. Not only prevents the puncture needle from tilting out of the chute due to lateral stress, but also enables the transfusion needle wing panel to smoothly slide into the limit groove.
Because the sleeve pinch handle is made of hard materials, the limiting groove cannot be loose due to external force, and the transfusion needle wing piece cannot slide out of the limiting protrusion, so that the transfusion needle is safer and more reliable.
The utility model has the advantages that: 1. the safe sleeve can be used more safely by designing the tail end chamfer edge of the safe sleeve, and is particularly suitable for children; 2. the structure is simple, the structure is exquisite, the limiting groove is skillfully formed in the handle knob made of hard material, and the wings of the infusion needle are limited in the limiting groove through the limitation of the limiting protrusion; is safe and reliable. 3. After the polluted needle head is sealed and protected, the needle head is blocked from being in direct contact with the outside, the possibility of needle stick injury is cut off, the occupational injury of nursing personnel is prevented, and meanwhile, the psychological pressure of occupational exposure of vast nursing workers is relieved.
Drawings
Fig. 1 is a schematic front structural view of the safety bushing of the present invention;
FIG. 2 is a schematic side view of the safety sleeve of the present invention;
in the figure: 1. the safety sleeve comprises a safety sleeve 2, a sleeve pinching handle 3, a limiting wedge-shaped surface 4, a sliding groove 5 and a chamfer edge.
Detailed Description
The structural features of the present invention will be further explained with reference to the accompanying drawings and specific embodiments.
As shown in figures 1 and 2, the sleeve of the safe transfusion needle comprises a puncture needle and a safe sleeve 1 for accommodating the puncture needle, wherein a transfusion needle wing panel is arranged at the joint of the puncture needle and a transfusion tube; a sliding groove 4 matched with a transfusion needle wing panel is arranged on the side wall of the safety sleeve; one or more limiting protrusions are arranged on the sliding groove 4; the root of the safety sleeve 1 is a sleeve handle 2, and the end of the safety sleeve 1 is a limiting wedge-shaped surface 3; and the edge of the end part of the limiting wedge-shaped surface 3 is provided with a smooth chamfered edge 5.
The edge of the end part of the limiting wedge-shaped surface 3 is turned outwards to form a smooth chamfered edge 5.
The sleeve pinching handle 2 is provided with a limiting groove which is communicated with the sliding groove, and the length from the sleeve pinching handle to the nearest limiting protrusion is smaller than the height of the transfusion needle wing.
In order to facilitate pushing the wing of the transfusion needle into the limiting groove, the end part of the sleeve is designed into a limiting wedge-shaped surface, and the lowest point of the limiting wedge-shaped surface is an inlet part of the sliding groove.
The number of the limiting bulges is three.
The preferred embodiment is that the height of the limiting groove is equal to the height of a wing piece of the transfusion needle, and the limiting projection closest to the sleeve handle is arranged at the joint of the sleeve and the sleeve handle.
