Description

Technical Field

[0001] The utility model belongs to the field of medical technology, and in particular relates to an infusion patch structure which can avoid skin damage caused by pressure from instruments. Background Art

[0002] Infusion patch is a medical device product, the main function of which is to fix the infusion line and catheter, prevent the line from sliding or falling off during medical operations such as infusion or venous blood collection, so as to ensure the safety and effectiveness of medical operations. Infusion patch can fix the infusion line on the patient's skin or other appropriate position, prevent the infusion line from moving due to the patient's movement or other reasons, and ensure the smooth flow and safety of the infusion line. By fixing the infusion line, the infusion patch can reduce the risk of infection caused by the movement of the infusion line, reduce the possibility of bacteria entering the blood circulation, and help protect the health of the patient. The use of infusion patch can make it easier for medical staff to fix the infusion line, reduce the cumbersome steps in the operation process, and improve work efficiency. Infusion patch can reduce irritation and discomfort to the patient's skin while fixing the infusion line, keeping the patient relatively comfortable. Infusion patch is a commonly used auxiliary tool in the medical environment, which has the functions of fixing the infusion line, reducing the risk of infection, improving the convenience of operation and alleviating the discomfort of the patient, and helps to improve the safety and efficiency of medical operations.

[0003] However, the infusion patch still has some disadvantages: 1. There is no special high-lift platform infusion patch in clinical practice; 2. The width and length of the disposable infusion patch commonly used in hospitals are not ideal for fixing indwelling needles (fixation is not firm); 3. Some fixed indwelling needles in grassroots hospitals require manual tearing of cloth tape or paper tape. Sometimes nurses will look for tape, which increases the workload of nurses. Because the length and width of the torn tape are not uniform, the clinical fixation effect varies (non-standard, unsightly); 4. If the indwelling needle is not fixed on a high-lift platform, it is easy to exert pressure on the local skin and cause pressure damage to the instrument. Utility Model Content

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figure 1-6The utility model provides a technical solution: an infusion patch structure that can avoid pressure-induced skin damage caused by equipment, comprising an upper adhesive patch 1, an operation area 2 is arranged in the middle of the surface of the upper adhesive patch 1, a lower adhesive patch 3 is arranged at the bottom end of the upper adhesive patch 1, and a middle adhesive patch 4 is arranged in the middle of the surface of the lower adhesive patch 3;

[0031] A thickening layer 5 is arranged on the inner side of the upper adhesive tape 1 , and an auxiliary structure 6 is arranged on the surface of the thickening layer 5 .

[0032] The length of the upper adhesive strip 1 is shorter than that of the lower adhesive strip 3, which will bring the following effects and advantages:

[0033] Reduced contact area: Since the length of the upper adhesive strip 1 is shorter than that of the lower adhesive strip 3, this means that the contact area of ​​the catheter close to the skin is smaller. This can reduce the burden and pressure on the skin, reduce irritation to the skin and the risk of potential damage. Greater flexibility: The shorter length of the upper adhesive strip 1 allows the flexibility of the catheter to be better maintained while fixing the catheter, without excessively restricting the range of motion of the catheter, which is beneficial to patient comfort and freedom of movement. Concentrated adhesion: Since the length of the upper adhesive strip 1 is shorter, the adhesion is concentrated in a smaller area, which can more accurately fix the position of the catheter, prevent the catheter from sliding or falling off, and better control the beauty and effect of fixation. When the length of the upper adhesive strip 1 is shorter than that of the lower adhesive strip 3, it can reduce the burden and irritation on the skin, maintain the mobility and stability of the catheter, and improve the concentration of adhesion, which is beneficial to improving the effect of fixing the catheter and the comfort of the patient.

[0034] The area of ​​the operating area 2 is equal to the area of ​​the middle adhesive 4, which will bring the following effects and influences:

[0035] Evenly distribute pressure: Since the area of ​​the operation area 2 is equal to the area of ​​the middle adhesive patch 4, the pressure of fixing the catheter can be evenly distributed in these two areas. This helps to avoid excessive or insufficient pressure on a certain part when fixing the catheter, reducing the risk of discomfort and damage to the skin. Improve the fixation effect: Ensuring that the area of ​​the operation area 2 is equal to the area of ​​the middle adhesive patch 4 can balance the force fixed on both sides of the catheter, increase the stability of the catheter on the skin, avoid the loosening or sliding of the catheter during the fixation process, and improve the fixation effect and safety. Reduce local pressure: The equal area of ​​the operation area 2 and the middle adhesive patch 4 also helps to reduce the local pressure in the fixed area, avoid the impact of long-term uneven pressure on the skin, and reduce the risk of skin damage. At the same time, the design of equal area of ​​the operation area 2 and the middle adhesive patch 4 also makes the operation of fixing the catheter simpler and more convenient, reducing the operator's operating errors and the patient's discomfort. When the area of ​​the operation area 2 is equal to the area of ​​the middle adhesive patch 4, it helps to evenly distribute the pressure of the fixed catheter, improve the fixation effect, reduce local pressure and simplify the operation steps, which can effectively improve the effect of catheter fixation and the comfort of the patient.

[0036] The engraving depth of the operation area 2 is less than the engraving depth of the middle adhesive 4, which will bring the following effects and influences:

[0037] Reducing local pressure: Because the engraving depth of the operation area 2 is shallow, compared with the deeper engraving depth of the middle adhesive 4, it may reduce the local pressure concentration. This helps to reduce the irritation and compression of the skin at the fixation site and reduce the risk of skin damage to the patient. Reducing skin irritation: The shallow engraving depth of the operation area 2 helps to reduce irritation and friction on the skin, reduce the possibility of skin discomfort or damage, and improve the comfort of the patient. Keep the catheter stable: Although the engraving depth of the operation area 2 is shallow, the support of the deeper engraving depth of the middle adhesive 4 can still effectively maintain the stability and fixation of the catheter to prevent the catheter from shifting or loosening. Different engraving depths can also bring obvious visual and tactile feelings during use, which helps the operator to correctly place and fix the catheter and simplify the operation process. When the engraving depth of the operation area 2 is less than the engraving depth of the middle adhesive 4, it may reduce local pressure, reduce skin irritation, maintain catheter stability and simplify operation, providing patients with a more comfortable and safe catheter fixation experience.

[0038] The thickness of the upper adhesive tape 1 is greater than the thickness of the lower adhesive tape 3, which will produce the following effects and influences:

[0039] Increase fixation stability: The thickness of the upper adhesive 1 is greater than that of the lower adhesive 3, which can provide more support and thickness, help increase the stability and firmness of catheter fixation, and reduce the risk of catheter movement or falling off. Increase durability: Since the thickness of the upper adhesive 1 is larger, it can withstand more tension and pressure, making the catheter fixation more durable and able to maintain the fixation effect for a long time without being easily damaged. Improve comfort: Although the thickness of the upper adhesive 1 is large, the thickness of the lower adhesive 3 is thinner, which can reduce the overall thickness of the fixation, which is conducive to reducing the sense of pressure on the skin and improving the comfort of the patient. Reduce friction and irritation: The increase in the thickness of the upper adhesive 1 can reduce the friction and irritation between the catheter and the skin, reduce the risk of skin damage, and reduce discomfort. When the thickness of the upper adhesive 1 is greater than that of the lower adhesive 3, it may increase fixation stability and durability, improve comfort, reduce friction and irritation, and thus improve the effect of catheter fixation and the comfort of the patient.

[0040] The surface curvature of the sandwich adhesive layer 602 is less than 180 degrees, which will bring the following effects and influences:

[0041] Better fit: Since the surface curvature is less than 180 degrees, the sandwich adhesive layer 602 will better fit the skin surface, reduce the generation of gaps and bubbles, and help improve the fit and stability of catheter fixation. Reduce edge peeling: A smaller surface curvature can reduce the overhang of the edge of the sandwich adhesive layer, reduce the risk of edge peeling, and extend the service life of the sticker. Improve comfort: Reducing the surface curvature can reduce the discomfort between the sticker and the skin and improve the comfort of the patient. Increase fixation stability: Better fit and fitting area can increase the fixation stability of the sandwich adhesive layer 602 and reduce the risk of movement and falling off. The surface curvature of the sandwich adhesive layer 602 less than 180 degrees may bring about better fit, reduce edge peeling, improve comfort, and increase fixation stability, which is beneficial to the improvement of catheter fixation and patient comfort.

[0042] The auxiliary structure 6 includes a curved adhesive sheet 601 and a sandwich adhesive layer 602. The surface of the thickened layer 5 is provided with the curved adhesive sheet 601, and the surface of the curved adhesive sheet 601 is provided with the sandwich adhesive layer 602. The area of ​​the curved adhesive sheet 601 is equal to the area of ​​the operating area 2, which will bring the following effects and influences:

[0043] More uniform support: The area of ​​the curved adhesive sheet 601 is equal to the area of ​​the operating area 2, which ensures uniform support for the catheter fixing area, helps to disperse pressure, and improves the comfort of fixation. Increase fixation: The sandwich adhesive layer 602 is arranged on the surface of the curved adhesive sheet 601, which can provide additional fixation and support, and help ensure the firmness and stability of the catheter fixation. Reduce the risk of displacement: The design of the combined curved adhesive sheet 601 and the sandwich adhesive layer 602 can effectively reduce the risk of displacement of the catheter fixing part and improve the safety of the catheter. Simplify operation: The design of the combined structure of the curved adhesive sheet 601 and the sandwich adhesive layer 602 helps to simplify the operation steps and improve the convenience and efficiency of the operation. The auxiliary structure 6 includes the curved adhesive sheet 601 and the sandwich adhesive layer 602, and the area of ​​the curved adhesive sheet 601 is equal to the area of ​​the operating area 2, which may bring more uniform support, increase fixation, reduce the risk of displacement and simplify operation, thereby improving the effect of catheter fixation and the comfort of the patient.

[0044] Working principle: Figure 1-6As shown, when using the infusion patch structure that can avoid pressure skin damage caused by equipment, first tear off the protective film of the upper adhesive patch 1, then tear off the protective film of the lower adhesive patch 3, stick the lower adhesive patch 3 on the patient's skin, and then use the upper adhesive patch 1 to fix the indwelling needle, PICC, medium and long lines, etc., and the operation area 2 and the middle adhesive patch 4 can help medical staff determine the sticking position between the patient's diseased part and the upper adhesive patch 1 and the lower adhesive patch 3. When a gap is generated between the upper adhesive patch 1 and the adhered pipe, tear off the first layer of the upper adhesive patch 1, and stick the curved adhesive sheet 601 and the sandwich adhesive layer 602 tightly to the pipe. This is the feature of the infusion patch structure that can avoid pressure skin damage caused by equipment.
