Description

Butterfly wing needle with needle head not easy to shift

Technical Field

The utility model relates to the technical field of medical appliances, in particular to a butterfly wing needle with a needle head not easy to shift.

Background

In clinic, some patients need to use butterfly wing needles for intravenous infusion. The butterfly wing needle comprises a needle wing, the front part of the needle wing is inserted with a needle head, and the rear part of the needle wing is provided with an extension tube. In order to protect and observe the puncture site of the butterfly wing needle, a medical transparent application with adhesiveness is covered on the puncture site of the butterfly wing needle, and the puncture site, the needle head, the needle wing, part of the extension tube and other parts of the butterfly wing needle are wrapped together, so that the puncture site is prevented from being infected by the external environment. Because the medical transparent application is transparent and visible, medical staff can directly observe the condition of the puncture position, if the conditions such as blood seepage and liquid seepage occur at the puncture position of the butterfly wing needle, the medical staff needs to tear off the medical transparent application to expose the puncture position, disinfect the puncture position and replace a new medical transparent application. However, the medical transparent application wraps the needle wings of the butterfly wing needle, the medical transparent application is adhered to the top surfaces of the needle wings, and medical staff can not tear the needle wings in the process of replacing the medical transparent application, so that the needle heads of the butterfly wing needle are shifted, and pain is brought to patients.

Detailed Description

The utility model is further described in detail below in connection with the detailed description.

The butterfly wing needle 1 with the needle not easy to shift is shown in fig. 1, and comprises a needle wing 2, the front part of the needle wing 2 is inserted with a needle head 3, the front part of the needle head 3 is exposed outside the needle wing 2, turns to the direction of the bottom surface of the needle wing 2, and is perpendicular to the bottom surface of the needle wing 2. An extension tube 4 extends out of the rear part of the needle wing 2, and the extension tube 4 is communicated with the needle head 3. Referring to fig. 2, the top surface of the needle wing 2 is covered with a first anti-adhesive layer 61, and the first anti-adhesive layer 61 is made of a silicone anti-adhesive coating. The needle wing 2 is butterfly-shaped and comprises a left needle wing body 21 and a right needle wing body 21. The bottom surfaces of the outer sides of the two needle wing bodies 21 are respectively provided with fixing wings 5 extending outwards, and the fixing wings 5 are glued on the bottom surfaces of the needle wing bodies 21. The top surface of the fixing wing 5 is mainly made of a transparent plastic film, and is covered with a second anti-adhesive layer 62, and the second anti-adhesive layer 62 is also made of an organosilicon anti-adhesive coating, as shown in fig. 2. The fixing wing 5 is shown in fig. 2, and has a pressing area 51 and an adhesive area 52 on the bottom surface thereof. The pressing area 51 is close to the needle wing 2, and is provided with a sponge 511; the attachment zone 52 is remote from the wings 2 and is provided with an attachment layer 521 for attaching the skin near the puncture site. In order to avoid the sponge 511 from being polluted by the seepage, the outer wall of the sponge 511 is covered with a waterproof layer (not shown) made of PU film, which wraps the sponge 511, so as to prevent the seepage from seeping into the sponge 511 to cause pollution. If the seepage flows to the adhesive layer 521, the adhesive force of the adhesive layer 521 may be weakened, and the adhesive layer 521 may be made of a material having a waterproof property so as to prevent the adhesive layer 521 from falling off.

After the medical staff pierces the needle head 3 of the butterfly wing needle 1 into the patient, the needle wing 2 is exposed on the skin of the patient near the piercing position and is not fixed, and the needle head 3 can be moved by external collision, so that the medical staff can use the adhesive layer 521 of the fixed wing 5 to adhere to the skin near the piercing position, thereby fixing the needle wing 2, and then use the medical transparent application (not shown) with adhesiveness to wrap the piercing position together with the needle head 3, the needle wing 2, part of the extension tube 4 and other parts of the butterfly wing needle 1. If the puncture part of the butterfly wing needle 1 bleeds, medical staff needs to tear off the medical transparent application to expose the puncture part, disinfect the puncture part and replace the new medical transparent application. In the process of tearing the medical transparent application from the second anti-adhesive layer 62, as the medical transparent application is covered on the second anti-adhesive layer 62 and is not contacted with the fixed wing 5, the fixed wing 5 is not pulled by the medical transparent application to shift, the pasting effect of the fixed wing 5 is not affected, and the fixed effect on the needle wing 2 is still kept. Under the state that the needle wing 2 is fixed by the fixed wing 5, medical staff tears the medical transparent application from the first anti-adhesive layer 61, and as the medical transparent application is covered on the first anti-adhesive layer 61, the adhesive force is weaker, the medical staff can easily tear the medical transparent application, and the needle wing 2 cannot be pulled by the medical transparent application, so that the needle head 3 cannot be driven to shift, and the pain of a patient cannot be brought to the patient.

If a new butterfly wing needle 1 needs to be replaced, after tearing off the medical transparent application, a medical staff can put a finger on the part of the second anti-adhesion layer 62 covered above the pressing area 51 and slightly apply a small force to press downwards, so that the butterfly wing needle 1 can be removed by fixing the butterfly wing 2 without touching the butterfly wing 2, tearing off the fixing wing 5 and pinching the two needle wing bodies 21 of the butterfly wing 2 by hands to pull out the needle head 3. During the pressing of the finger, since the sponge 511 provided in the pressing area 51 has a certain thickness, the downward pressing force of the finger can be buffered, and the pressing force of the finger is transmitted to the needle 3 very little, and the needle 3 is hardly displaced. During the tearing of the fixing wing 5, since the needle wing 2 is pressed and fixed by the finger, the needle wing 2 is not pulled by the fixing wing 5. In this way, the displacement amplitude of the needle 3 is very small and the patient does not feel very painful during the whole process of operating the removal of the winged needle 1.

The above-described embodiments are provided for the present utility model only and are not intended to limit the scope of patent protection. Insubstantial changes and substitutions can be made by one skilled in the art in light of the teachings of the utility model, as yet fall within the scope of the claims.
