Description

Indwelling needle application capable of preventing phlebitis

Technical Field

The utility model relates to the technical field of medical auxiliary articles, in particular to an indwelling needle application capable of preventing phlebitis.

Background

The use of the indwelling needle for medication (infusion) can reduce the pain of the patient caused by repeated venipuncture and the fear of injection, is convenient for clinical medication, emergency medication of critical patients and reduction of the workload of nurses, so the venous indwelling needle is widely applied clinically. However, in the clinical intravenous infusion process using the indwelling needle, patients are prone to phlebitis due to the infusion of drugs or the long-term use of the indwelling needle, and the indwelling needle needs to be replaced frequently for infusion. After phlebitis appears, treatment is needed, and clinically, Meipi kang is used for preventing the phlebitis, and after the phlebitis appears, treatment is needed. Clinically, a preventive patch is often used to prevent phlebitis.

Patent No. CN206355396U discloses a venous indwelling needle application, which utilizes the thin effect of a liquid suction catheter to absorb sweat in a puncture part and discharge the sweat to the outside of an application body, thereby achieving the purposes of avoiding pollution and preventing bacterial infection. However, in such a structure, liquid outside the dressing can also permeate into the dressing through the liquid suction catheter, and the dressing viscosity is easily influenced after a long time, so that the liquid falls off, and the effect of fixing the indwelling needle on the puncture site of a patient is influenced; and after the indwelling needle is punctured, the application paste is propped open by the indwelling needle, a gap is easily left between the application paste and the skin of a patient, dust and the like easily enter from the gap, and the patient is infected with external bacteria.

SUMMERY OF THE UTILITY MODEL

To the technical defect who exists among the prior art, the utility model provides a but prevent phlebitis's lien needle is applied ointment or plaster.

In order to achieve the above object, the utility model discloses technical solution is: an indwelling needle patch for preventing phlebitis comprises a reinforcing layer, a back lining layer, an inner adhesive layer and a medicinal layer. The back lining layer is made of waterproof and breathable materials; the inner adhesive layer is positioned below the back lining layer and is soft silicone adhesive; the medicine layer is adhered to the middle part of the lower surface of the inner adhesive layer, is a medicine special for treating and preventing phlebitis, and can be in the form of fine particles or powder. The reinforcing layer is annular, the inner diameter of the reinforcing layer is smaller than that of the back lining layer, the outer diameter of the reinforcing layer is larger than that of the back lining layer, and the reinforcing layer is bonded on the back lining layer; the reinforcement layer has a ductility greater than that of the backing layer; the outer adhesive layer which is different from the inner adhesive layer in material is coated below the reinforcing layer, and the viscosity of the outer adhesive layer is greater than that of the inner adhesive layer. The outer adhesive layer can be pressure-sensitive adhesive. The back lining layer can be made of transparent materials, so that medical personnel can conveniently see the situation of the puncture point at any time, and the patient can be treated in time when phlebitis appears.

The application (self-adhesive soft silicone foam dressing) which is clinically used for treating phlebitis has a good effect, the backing layer adopted by the application is made of foam materials and is easy to wet, the soft silicone materials are self-adhesive, and the application has the characteristics of not sticking to a wet wound surface and only sticking to dry and comfortable skin and is easy to fall off when meeting moisture. The utility model uses waterproof material as the back lining layer, which has waterproof performance; the inner adhesive layer is made of soft silicone, has self-adhesion, keeps the wound surface which is not sticky and moist, and only adheres to dry and comfortable skin; establish the outer viscose layer that viscidity is greater than interior viscose layer outside simultaneously for increase the utility model discloses a fixity prevents to drop in the use, causes the circumstances such as keeping somewhere needle aversion to take place. And the better ductility reinforcing layer can reduce the clearance between the indwelling needle and the skin surface and prevent dust, germs and the like from entering the puncture part of the indwelling needle from the clearance. The adhesive dressing has the advantages of simple structure, low cost compared with a beautiful skin-care dressing, low middle viscosity, strong self-adhesion, no wound injury, strong edge viscosity and displacement prevention.

Further, the medicine layer extends forwards from the middle to form a strip shape, and the strip shape is not limited to an oval shape, a rectangular shape and the like. The strip-shaped medicine layer can cover the part of the needle head of the remaining needle which is penetrated into the vein of the patient, and further effectively prevent the phlebitis of the patient.

Furthermore, a first transverse sticker and a second transverse sticker are arranged on the front side of the reinforcing layer; one side of the first transverse sticker is fixedly connected with the reinforcing layer; one side of the second transverse sticker is fixedly connected with the reinforcing layer; the first transverse paste and the second transverse paste are opposite to the connecting part of the reinforcing layer. When in use, the first transverse patch and the second transverse patch can be respectively and directly adhered to the skin and the tail part of the indwelling needle; can further strengthen like this the utility model discloses the adhesion strength who applies ointment or plaster improves the steadiness of keeping somewhere the needle, reduces to keep somewhere the gap between needle and the skin surface.

Furthermore, a water absorption ring is arranged in the middle of the lower surface of the back lining layer, and the water absorption ring is internally rich in the antibacterial agent; the back lining layer positioned on the inner side of the water absorption ring is made of transparent materials. The water absorption ring can be used for absorbing liquid exuded from puncture part and sweat discharged from skin at middle part of back lining layer, keeping puncture part of indwelling needle dry, and further preventing phlebitis.

Furthermore, an inner concave notch is arranged in the middle of the front side of the reinforcing layer, and at least two point-breaking tearable lines parallel to the edge of the inner concave notch are arranged on the inner side of the inner concave notch. The concave gap further reduces the gap between the indwelling needle and the surface of the skin; according to the size of the outer diameter of the indwelling needle, whether the indwelling needle is torn off along the point-breaking tearable line or not can be selected, the diameter of the concave notch is enlarged, and the indwelling needle is kept attached to the skin of a patient completely through the reinforcing layer.

Furthermore, an expansion eliminating hole is formed in the bonding part of the first transverse sticker and the reinforcing layer. The expansion hole is used for expansion generated when the first transverse paste is attached, and tearing and disconnection of the first transverse paste caused by stress concentration are avoided.

Furthermore, a plurality of glue-free areas which are not coated with the outer adhesive layer are arranged on the side edge of the reinforcing layer; the glue-free area is in a semi-elliptical shape with the arc length not less than 1 CM. There is not gluey district edge the utility model discloses tear the operation after the use, reduce medical personnel's work load.

Through adopting foretell technical scheme, the beneficial effects of the utility model are that:

1. establish the outer viscose layer that viscidity is greater than interior viscose layer in the outside for increase the utility model discloses a fixity prevents to drop in the use, causes the circumstances such as keeping somewhere the needle aversion to take place, increases the firm of keeping somewhere the needle.

2. The reinforcing layer with better ductility can reduce the clearance between the indwelling needle and the surface of the skin and prevent dust, germs and the like from entering the application (the puncture part of the indwelling needle) from the clearance.
