Description

Technical Field

[0001] The invention relates to, in particular to, an indwelling needle decompression dressing which is convenient for fixing an extension tube. Background Art

[0002] Intravenous therapy is one of the most commonly used and effective drug administration methods in clinical practice, with the characteristics of rapid drug onset and good efficacy. Peripheral venous indwelling needle puncture technology has become one of the basic technical operations in clinical nursing. In clinical practice, transparent dressings to fix indwelling needles + tape to fix extension tubes are conventional fixation methods. The disadvantage is that the fixation is cumbersome. When the tape fixes the extension tube on the transparent dressing, the tape and the dressing cannot be easily separated, which will affect the use of the extension tube and cause the dressing to loosen and curl, requiring the dressing to be replaced; when the tape is fixed on the patient's skin, the tape can be easily torn off, and the extension tube is more convenient to use, but the patient's skin is prone to tape marks and difficult to clean. Both methods will increase the workload of nurses. When the extension tube is fixed, it is in direct contact with the patient's skin. When the infusion is long-term or the patient's skin condition is poor, it is easy to cause local pressure injuries.

[0003] Patent CN202321565407.X discloses that the indwelling needle dressing for preventing pressure sores includes: a first dressing and a second dressing; wherein the first dressing includes: a dressing body, a first release paper, a catheter seat placement groove, a handheld placement groove, and a plurality of hose placement grooves; a decompression groove is also provided on the first dressing to reduce the contact area between the dressing body and the skin and thus reduce the pressure; the second dressing separates the first dressing from the third dressing, which can not only limit the indwelling needle, but also prevent the indwelling needle from causing pain to the patient when the third dressing is torn off. Decompression is carried out by setting a decompression groove, and the structure is complicated. Summary of the invention

[0004] The purpose of the present invention is to overcome the defects of the above-mentioned prior art and provide a decompression dressing for an indwelling needle that is easy to fix the extension tube. It has the function of adjusting and replacing the fixed position of the indwelling needle catheter at any time, simplifies the fixation of the indwelling needle extension tube, facilitates clinical nursing operations, optimizes the operating process, reduces skin stains and pollution, and reduces local pressure injuries of patients.

[0005] The present invention adds a 1-2 cm re-coverable sticking device on the front end of the original transparent dressing to fix the extension tube part. The re-coverable device makes the extension tube more convenient to use, and a decompression dressing is added to the bottom layer to protect the skin. The integrated dressing can solve the problem of indwelling needle fixation and extension tube fixation at one time, reduce the usage rate of adhesive tape, help keep the patient's skin clean, and increase patient satisfaction.

[0006] On the basis of the original indwelling needle fixation dressing, a transparent removable decompression patch is added to the front end to fix the indwelling needle extension tube, which is convenient for clinical operation fixation, reduces the use of tape, avoids skin tape marks, and improves skin cleanliness and patient comfort. The part of the fixed extension tube that contacts the skin uses a similar hydrocolloid dressing material, which has a decompression effect and prevents the extension tube from pressing on the local skin to form pressure sores.

[0007] The present invention provides an indwelling needle decompression dressing that is convenient for fixing an extension tube, comprising a transparent dressing and a fixing component arranged at the front end of the transparent dressing;

[0008] The fixing assembly comprises: a bottom layer, a middle layer, and an upper layer;

[0009] The bottom layer contacts the skin; the middle layer is the fixing layer of the indwelling needle extension tube, which is made of medical film material, smooth and non-sticky; the upper layer is a medical adhesive layer, which is split in the middle into two and can be peeled off at both ends, and the two ends are pressed together with the middle layer and the bottom layer. The adhesive layer is soft and similar to film material, with strong viscosity and easy to fix. It can be used to stick and fix extension catheters of different shapes to the fixing layer, and can be repeatedly pasted, making it easy to remove the extension tube for use.

[0010] Furthermore, the size of the transparent patch is 6×7 cm.

[0011] Furthermore, the fixing component has a width of 1 to 2 cm.

[0012] Furthermore, the bottom layer contacts the skin and is made of ultra-thin hydrocolloid dressing material, which increases the skin protection and pressure relief functions and prevents skin pressure damage.

[0013] Furthermore, the bottom layer is made of hydrophilic polymer, elastomer or medical pressure-sensitive adhesive.

[0014] Furthermore, both ends of the upper layer are provided with hand-held lid-opening places, and the hand-held lid-opening places are provided with release paper without stickiness.

[0015] Furthermore, the middle layer is a PET film or a TPU film.

[0016] Furthermore, the indwelling needle extension tube is arranged between the middle layer and the upper layer.

[0017] Furthermore, when it is necessary to fix the indwelling needle extension tube, one end of the upper layer is lifted up, the indwelling needle extension tube is placed on the middle layer, and then the upper layer is lowered and gently pressed to make the indwelling needle extension tube fit with the middle layer to complete the installation of the indwelling needle extension tube, and then the two ends of the upper layer are folded inward to cover the surface of the middle layer, and pressed again to make it stick firmly.

[0018] Furthermore, the bottom layer is provided with anti-slip grooves.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] The indwelling needle decompression dressing provided by the present invention improves the adhesive part structure of the traditional dressing, and designs the adhesive layer to be formed by pressing the upper layer and the middle layer which are divided into two parts by breaking in the middle, so that the adhesive layer has the characteristic of being easy to separate, thereby having the function of adjusting and replacing the fixed position of the indwelling needle catheter at any time. The present invention increases the fixing function of the original indwelling needle transparent dressing, simplifies the fixing of the indwelling needle extension tube, facilitates clinical nursing operations, optimizes the operation process, reduces skin stains and pollution, reduces local pressure injuries of patients, reduces the workload of basic nursing, and increases patient satisfaction.
