Description

Technical Field

[0001] The invention relates to a medical rehabilitation tool, in particular to a wound protection device after cardiac surgery. Background Art

[0002] Cardiac surgery is also known as cardiovascular surgery. Different from the interventional treatment and drug treatment of cardiology, it generally corrects and removes the patient's lesions through surgical treatment. As we all know, when it comes to cardiac surgery, in most cases, it involves the establishment of surgical incisions. Therefore, the recovery of postoperative incisions becomes an extremely important part of postoperative rehabilitation.

[0003] In the traditional way, after the wound is sutured, the wound is covered with gauze coated with liquid medicine, and the gauze is properly closed with bandages and dressings to protect the wound. However, in clinical practice, we found that this traditional method, which only relies on gauze, dressings and bandages to provide soft protection for the wound, significantly restricts the patient's movement. This is mainly because the skin near the wound is pulled or squeezed in a certain posture during the movement of the patient, resulting in strong pain in the wound that has not been completely healed, and in severe cases, there is still a risk of the wound being torn again.

[0004] At present, some postoperative wound protection devices have appeared in many existing literature technologies. They are generally wearable protective plates. The protective plates have a certain degree of rigidity and multiple properties such as waterproofness. They can prevent a certain degree of impact, realize impact protection of the wound, and realize dressing changes and other operations through the openable wound set on the protective plate. It can be said that in fact, the risk of passive impact of surgical wounds is actually very low. More often, it is due to the patient's own activities that the skin around the wound is pulled and squeezed, causing damage. However, this protective structure in the above scheme is no different from the traditional method of gauze compression. It cannot achieve local hardening protection of the skin near the wound, and it is actually meaningless to prevent the skin near the wound from being pulled and squeezed.

[0005] Therefore, how to truly solve the problem of wound protection for patients, so as to improve the comfort of patients and reduce the limitation of their movements, is an extremely important issue in this field. Summary of the invention

[0006] The purpose of the present invention is to provide a post-cardiac surgery rehabilitation auxiliary device capable of achieving sclerosis protection of the skin around the wound.

[0007] To achieve the above-mentioned invention object, the technical solution adopted by the present invention is: a post-cardiac surgery rehabilitation auxiliary device, comprising a square hardening frame for installation on the skin outside the wound;

[0008] and a hardening adhesive, wherein the hardening adhesive is used to adhere the hardening frame to the skin and form a hardened layer on the skin surface;

[0009] It also includes a positioning film, one side of which is attached with a backing adhesive sheet by means of a self-adhesive sticker; the positioning film is provided with a positioning notch that matches the shape and size of the hardening frame;

[0010] When using: tear off the adhesive backing sheet on the positioning film, and stick the positioning film on the skin along the length direction of the wound; then apply the hardened adhesive on the positioning film and fill the positioning gap; then align the hardening frame with the positioning gap and stick it on the skin at the positioning gap; tear off the positioning film, and after the hardening adhesive dries, a hardened layer is formed on the skin surface, and double hardened with the hardening frame.

[0011] Preferably, the hardening frame is made of low-temperature thermoplastic plastic and can be molded into a shape consistent with the extension of the patient's skin near the wound.

[0012] Preferably, the inner circle and the outer circle of the positioning coating are connected via two connecting sections, and the connecting sections are respectively located at two ends of both sides of the positioning coating to form an interlaced pattern.

[0013] Preferably, the hardened frame is symmetrically provided with a plurality of side convex columns on the left and right sides, and also includes a plurality of elastic spacers corresponding to the logarithm of the side convex columns, and small circular holes are provided at both ends of the elastic spacers, and the elastic spacers are sleeved on the side convex columns through the small circular holes.

[0014] Preferably, the hardened frame is provided with an end boss at one end and a slit at the other end; and further comprises a covering belt, one end of which is also provided with a small circular hole, and is sleeved on the end boss through the small circular hole, and the other end passes around the slit and is connected to itself with Velcro.

[0015] Preferably, when in use, the skin surface in the hardening frame is filled with medical gel.

[0016] Preferably, when in use, the hardening frame is also covered with a layer of medical dressing.

[0017] The beneficial effects of the present invention are mainly embodied in:

[0018] 1. By constructing a hardened layer on the skin surface near the wound, the skin inside the hardened layer (that is, the skin near the wound) forms a relatively independent whole part. When it is pulled and squeezed, this part of the surface skin can form an overall movement, reducing the influence of squeezing and pulling forces on the wound; and the hardened layer can also play a certain supporting role, which can better protect the wound.

[0019] 2. By attaching a hardening frame to the surface of the hardening layer, the hardening frame can form double hardening together with the hardening layer, which can greatly protect the area around the wound, further strengthen the integrity of the skin around the wound, further reduce the risk of traction and compression of the wound after surgery, relieve pain, avoid wound damage, and can greatly improve the patient's limited mobility.

[0020] 3. The present invention provides a new idea for constructing local protection at the postoperative wound of the patient, and the structure is simple and easy to implement, with good universality, and is suitable for large-scale promotion and application in clinical practice.

[0029] like Figure 1-8 As shown, a rehabilitation auxiliary device or tool used after cardiac surgery, especially a device that can perform regional annular hardening protection on the skin around the wound, thereby relieving the skin around the wound from pulling tension and squeezing force, reducing pain, and preventing wound tearing. It can greatly improve the patient's restricted activity after surgery and enable the patient to have a more comfortable experience after surgery.

[0030] Specifically, the present invention includes Figure 3As shown in the figure, a square hardening frame 1 is used to be installed on the skin outside the wound. The hardening frame 1 is usually formed by hard plastic processing, and each patient uses it once, and the width of a single side is 0.7-1.5CM. Regarding the size of the wound, it can be large, medium and small. The large size is about 8-10CM long and 4-5CM wide; the medium size is about 6-8CM long and 3-4CM wide; the small size is about 4-6CM long and 2-3CM wide; to adapt to wounds of different lengths. Since the skin at the wound is not an ideal pure plane, but has a certain curvature, and for people of different body shapes and wounds in different parts, the differences are relatively large. In order to adapt to the skin morphology at the wound, the hardening frame 1 described in the present invention is made of low-temperature thermoplastic plastic and can be molded into a shape consistent with the extended shape of the skin near the patient's wound. The low-temperature thermoplastic plastic can have sufficient hardness at room temperature to meet the support and protection requirements, but through hot air blowing and hot water, it can be shaped under lower temperature conditions, so that it can be completely matched with the skin morphology and achieve a better fitting effect.

[0031] The present invention also includes a hardening adhesive 2, which is used to adhere the hardening frame 1 to the skin and form a hardened layer on the skin surface. Compared with conventional common medical adhesives, the hardening adhesive 2 has better film-forming properties and better hardness after film formation, and can harden and protect the local skin, so that the skin inside the hardened layer forms a relatively independent area, which itself has independent skin surface hardening properties, and after the hardening frame is attached in place, the two can cooperate to form secondary hardening.

[0032] The present invention also includes Figure 1 The positioning film 3 shown is mainly used to facilitate the coating of the hardening adhesive and reduce the discomfort caused by too large a skin coating area. It can also provide a reference for the installation of the hardening frame, facilitating the positioning and pasting of the latter. The positioning film 3 is in the form of a self-adhesive backing, that is, one side of the positioning film 3 is attached with a backing sheet through a self-adhesive sticker. The positioning film 3 is provided with a positioning notch 4 that matches the shape and size of the hardening frame 1. When in use, the hardening frame 1 is pasted according to the positioning notch 4. Due to the special shape of the positioning film 3, including the inner and outer circles, in order to form a whole during processing for easy use, such as Figure 1 As shown in , the inner ring and the outer ring of the positioning film 3 are connected by two connecting sections 5, and the connecting sections 5 are respectively located at both ends of the positioning film 3 to form an interlaced state. This method can not only ensure its integrity, but also make the positions of the positioning notches 4 not directly opposite to each other, avoiding the disadvantageous situation that the hardened layer formed by the hardened adhesive has opposite ports.

[0033] The use of the present invention is as follows: first, disinfect the skin around the wound with iodine, and after the skin is dried, tear off the adhesive backing sheet on the positioning film 3, and paste the positioning film 3 on the skin along the length direction of the wound, the length direction of the positioning film 3 is consistent with the length direction of the wound, and the wound is in the middle. Then, open the bottled hardened adhesive 2, apply it on the positioning film 3, and fill the positioning gap 4. Then, align the hardening frame 1 with the positioning gap 4 and paste it on the skin at the positioning gap 4. After the position is accurate and basically stable, tear off the positioning film 3, and after the hardening adhesive 2 is dried, a hardened layer can be formed on the skin surface, and double hardening is formed with the hardening frame 1.

[0034] Of course, in the above embodiments, the skin hardening protection scheme of the present invention has been described. In order to cover the wound area in the center of the hardening frame 1, the present invention can directly cover it with a bandage, gauze, etc. However, since the bandage lacks a stable foundation, it often needs to be wrapped around the trunk, which is easy to directly affect the hardening frame 1, so that the hardening frame 1 has a certain risk of falling off.

[0035] Therefore, it is better to use the covering protection of the present invention directly relying on the hardening frame 1, specifically, as Figure 5 As shown in the figure, the hardening frame 1 is symmetrically provided with a plurality of side bosses 6 on the left and right sides, and also includes a plurality of elastic spacers 7 corresponding to the logarithm of the side bosses 6. The two ends of the elastic spacers 7 are provided with small circular holes, and are sleeved on the side bosses 6 through the small circular holes. The number of elastic spacers 7 is designed according to the size of the hardening frame 1, so as to basically completely cover the center of the hardening frame 1. For a clearer display, the elastic spacers 7 shown in the figure are relatively sparse. At the same time, one end of the hardening frame 1 is provided with an end boss 8, and the other end is provided with a slit 9. It also includes a covering belt 10, one end of the covering belt 10 is also provided with a small circular hole, and is sleeved on the end boss 8 through the small circular hole, and the other end is connected with itself by hook and loop after passing the slit 9. Through the vertical and horizontal coverage of the elastic spacers 7 and the covering belt 10, the overall covering effect is better.

[0036] In addition, see Figure 7 and 8 As shown in the figure, when in use, a better way of the present invention is that the skin surface in the hardening frame 1 is filled with medical gel 11. The hardening frame 1 is also covered with a layer of medical patch 12. The medical gel 11 can effectively isolate the external environment to prevent bacterial interference and water seepage. The medical patch 12 mainly plays the role of external covering.
