Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical and health care devices, specifically a combinable salt bag for postoperative compression, suitable for scenarios such as joint pain, muscle strain, and wound care. Background Technology
[0002] Traditional salt bags are mostly rectangular or square in shape, and are fixed by tape or straps, which has the following shortcomings: 1. Existing salt bags are easy to cause skin damage when fixed by tape or straps, have poor fixation, and may shift, leading to compression failure; 2. Traditional salt bags are mostly designed with a single volume, which cannot adapt to the shape of different anatomical sites such as joints and chest walls; 3. The pressure adjustment method is limited and cannot achieve local pressure gradient changes through combination; 4. They have poor reusability and are difficult to disinfect and maintain. Summary of the Invention
[0003] The purpose of this invention is to provide a combinable saline bag for postoperative compression, which can form a stable honeycomb structure with uniform pressure distribution; it can also be freely combined according to surgical needs, with flexible pressure adjustment to achieve local pressure gradient changes, and is suitable for more scenarios and sites.
[0004] The technical solution adopted by this utility model is: a combinable saline bag for postoperative compression, including a saline bag body, the front and back of the saline bag body are both hexagonal, and each side of the hexagon is sewn with double-sided hook and loop fasteners, wherein the hook side of the double-sided hook and loop fasteners faces upward and the loop side faces downward.
[0005] The salt bag body has a side surface between the front and back, with an opening on the front side that is attached with Velcro.
[0006] The salt bag body has different sizes and models of salt bags, which are filled with 200~1000g of ordinary bagged table salt or medical sodium chloride granules.
[0007] Salt bags of different sizes and models can be freely combined to form honeycomb-shaped and chain-shaped combination salt bags.
[0008] The combinable salt bag is made of medical-grade waterproof and breathable fabric.
[0009] Compared with traditional salt bags in the prior art, this utility model has the following advantages:
[0010] 1. Because the front and back of the salt bag are both hexagonal, a stable honeycomb structure can be formed;
[0011] 2. This utility model has salt bags of different sizes and models, filled with different weights of salt, which can be freely combined according to surgical needs. The pressure can be flexibly adjusted to achieve local pressure gradient changes, thus making it suitable for more scenarios and sites.
[0012] 3. The salt bag of this utility model can be directly pasted onto the patient's gown or gauze, which is easy to clean and disinfect, and has good reusability. Attached Figure Description

[0017] Other features and advantages of this utility model will be described in detail in the following detailed description section; moreover, all parts not described in this utility model are the same as or can be implemented using existing technology. The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this utility model.
[0018] from Figure 1 As can be seen, this utility model is a combinable saline bag for postoperative compression, including a saline bag body 1. The front and back of the saline bag body are both hexagonal, and each side of the hexagon extends outward with a flexible edge 2 of 2-4 cm. The flexible edge adopts a double-sided Velcro design, with the hook side 3 facing up and the rough side 4 facing down. The front and back of the saline bag body are connected by a side of a certain width, with an opening 7 on the front side. The upper cover 5 of the opening is a single Velcro rough side, and the lower cover 6 of the opening is a single Velcro hook side.
[0019] Except for the Velcro, the salt bag of this utility model is made of medical-grade waterproof and breathable fabric that conforms to the YY / T 0506 standard.
[0020] This utility model has salt bags in three different sizes: large, medium, and small. They can be filled with 200-1000g of ordinary bagged table salt or medical sodium chloride granules. The salt bags of different sizes can be freely combined to form various combination forms such as honeycomb and chain. They are used in common application scenarios such as chest wall, groin, and joints, including after heart pacemaker implantation, after femoral artery interventional surgery, and after thyroidectomy.
[0021] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.
