Description
Technical Field
The utility model relates to a prevent unexpected draw liquid needle that drops belongs to transfusion system technical field.
Background
The infusion is a disease treatment mode commonly used in hospitals, the connection mode between the infusion bottle and the liquid guiding needle is simple at present, and due to the fact that no fixing measures are provided, when arms of medical care personnel or patients touch the liquid guiding tube carelessly, the liquid guiding needle is easy to pull, and particularly when children patients are in infusion, the children are loved to play due to the nature of the children, so that the liquid guiding needle is easy to separate from the infusion bottle.
At present, in infusion safety control, the syringe needle accident drops and becomes common infusion safety problem in clinical infusion, and at the use transfusion system infusion liquid medicine in-process, the syringe needle drops under external force, and outside air just can get into at this moment and draw liquid needle and infusion bottle inside, and the syringe needle drops and need reinsert, and the syringe needle reinserts the harm that causes and has following several aspects: 1. the whole bag of transfusion causes pollution and has infection risk; 2. after the needle head is polluted, the needle head needs to be replaced, so that the waste of the infusion apparatus and the waste of the liquid medicine are caused; 3. the workload of nurses is increased; 4. increase the economic burden of the patient; 5. increase the contradiction between doctors and patients.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome prior art not enough, provide an anti-drop draws liquid needle of transfusion system, through the transformation to the current liquid needle structure of drawing, solve because of dragging the transfer line and cause the phenomenon that draws the liquid needle and drop.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides an accidental dropping prevention draws liquid needle, includes syringe needle and needle file, its characterized in that: the steel wire rope also comprises an elastic wing and a steel wire rope;
the needle head is made of stainless steel materials, the interior of the needle head is hollow, a group of grooves are symmetrically formed in the outer wall of the needle head, the grooves are located in the middle of the needle head, a through hole is formed in the bottom end of each groove, an elastic wing piece is placed in each groove, each groove is used for containing the elastic wing piece which retracts radially under external force, and the needle head plays a role in drainage;
the needle seat is arranged at one end of the needle head and is tightly attached to the bottom of the infusion apparatus, the interior of the needle seat is hollow, the material of the needle seat is any one of PVC, EVA, silica gel and rubber TPE, the needle seat can effectively seal the joint of the needle head and the infusion apparatus, and the outflow of liquid medicine in the infusion apparatus is avoided;
the both ends of elasticity fin are the rectangle, connect the both ends of elasticity fin to be a hypotenuse, the elasticity fin is by thickness 0.3mm ~ 0.6mm, the width is the beryllium bronze piece bending of 1mm ~ 1.5mm and forms, the one end rectangle laser welding fixed connection of elasticity fin is on the recess of syringe needle, the hypotenuse and the other end of elasticity fin are as one side of free end orientation needle file, the elasticity fin outwards protrudes for the outer wall of syringe needle, the other end of elasticity fin has the aperture, the hypotenuse of elasticity fin is 10 ~ 15 for the inclination of the axis of syringe needle. The elastic wing piece can always ensure the outward convex state relative to the outer wall of the needle head when not stressed, and can be bent and retracted into the groove of the needle head when stressed;
one end of the steel wire rope is fixed in the small hole at the free end of the elastic wing piece, the steel wire rope penetrates through the through hole below the groove of the needle head, and the diameter of the steel wire rope is 1 mm-1.5 mm. The arrangement of the steel wire rope can enable the needle head to be pulled out from the infusion apparatus, and the utilization rate of the needle head is improved.
More preferably, the number of recess on the syringe needle is 2 ~ 4, and is further, the number of recess on the syringe needle is 2. This is because the experimental data show that: open a recess, the syringe needle receives external force to pull easy slope, and when the syringe needle inserted in the transfusion system, is difficult to insert, and 2 ~ 4 recesses are arranged to the symmetry formula, and the syringe needle inserts easily, and 2 elastic wing sets up, even under the external force effect, the syringe needle also is difficult to pull out in the transfusion system, from manufacturing cost angle consideration, preferentially chooses for use to set up 2 recesses on the syringe needle.
Preferably, the distance between the rectangular piece at the free end of the elastic wing and the needle seat opposite to the rectangular piece is slightly larger than the thickness of the rubber plug 4 of the infusion bottle. By the arrangement, after the needle head is inserted into the infusion apparatus, the elastic wing pieces are completely opened, and the elastic wing pieces play a role in preventing falling.
Preferably, after the elastic wing panel retracts radially under the action of external force, the end face of the bevel edge does not protrude out of the outer wall of the needle head. So set up, be convenient for the syringe needle to insert in the transfusion system.
The working principle of the utility model is as follows:
during the use, at first medical personnel hold the syringe needle, and insert the syringe needle in the transfusion system, at syringe needle male in-process, external force extrusion elastic wing piece makes it contract in to the recess of syringe needle, after elastic wing piece is totally by extrusion shrink to the recess in, the syringe needle inserts in the transfusion system smoothly, hug closely the bottom of transfusion system until the needle file, effect through the needle file, can effectually seal syringe needle and transfusion system junction, the liquid medicine outflow in the transfusion system has been avoided, after elastic wing piece gets into the transfusion system in, under the effect of resilience power, elastic wing piece resumes original state, when the syringe needle receives the exogenic action, open because of elastic wing piece, elastic wing piece can prevent to cause the drawing liquid needle to break away from phenomenons such as transfusion system because of external force pulls, at this moment, liquid medicine in the transfusion system alright infuse the patient through drawing the outflow of liquid.
Once the needle is inserted into the infusion apparatus, the needle cannot be pulled out under the action of external force, and the elastic wing pieces cannot prevent the needle from falling off from the infusion apparatus because no corresponding groove is formed in the needle to accommodate the upward-turned elastic wing pieces in the upward-turning process. If the needle head needs to be pulled out, the steel wire rope can be pulled, the steel wire rope tensions the elastic wing piece to enable the elastic wing piece to be contracted into the groove of the needle head, after the elastic wing piece is completely pulled back to be contracted into the groove, the elastic wing piece does not block the needle head any more, and the needle head can be smoothly pulled out of the infusion apparatus.
Because the above technical scheme is adopted, the utility model discloses a beneficial technological effect as follows:
a) the utility model adopts the structure of the elastic wing panel, which solves the problem that the prior syringe needle is easy to fall off;
b) the needle head of the utility model can be pulled out under certain conditions, after a certain bottle of transfusion device is used up,
the other bottle can be replaced, the use efficiency of the needle head is improved, the trouble of looking for the needle head again is avoided,
and the cost is also saved.
