[0002] In the rapid development of the medical industry in recent years, many cutting-edge technologies have emerged, which has also increased the demand for secondary processing of medical consumables, including coatings. Many medical consumables have certain requirements for hydrophilicity, hydrophobicity, antibacterial properties, or anticoagulant properties. Therefore, it is necessary to add a special coating to the product to meet these requirements. After adding the coating, ultraviolet irradiation or high-temperature baking is then applied to increase the stability of the coating.
[0003] In practical applications, most products do not require full-coverage coating. Most products only need coating a small section, leaving the rest uncoated. Current technology typically involves applying a coating to specific areas of the product and then subjecting it to UV irradiation or high-temperature baking. However, this method can damage the uncoated portions of the product due to UV radiation or high temperatures, thus reducing the product yield. Furthermore, the diverse shapes of medical consumables increase the difficulty of adapting them to coating devices, posing significant challenges to mass production coating processes.
[0004] Therefore, there is an urgent need for a medical coating for jig shells that can overcome the above-mentioned defects. Utility Model Content

Additionally, the term "connection" here includes any direct and indirect electrical connection means. Indirect electrical connection means include connections made through other means.
[0029] Please see Figure 1 , Figure 1 This is a schematic diagram of a medical coating fixture shell, which includes a shell 1 and a shell cover 2. The shell 1 has a receiving cavity 9 and a receiving groove 4. One end of the receiving groove 4 communicates with the receiving cavity 9, and the other end penetrates the side wall of the shell 1. The receiving groove 4 is used to position the product to be coated, and the receiving cavity 9 is used to accommodate the part of the product to be coated that does not need to be coated. The part of the product to be coated that needs to be coated is located outside the shell 1. The receiving groove 4 is also provided with a pressing block groove 5, which intersects with the receiving groove 4. The shell cover 2 is also provided with a product pressing block 6, which corresponds to the position of the pressing block groove 5. After the shell cover 2 is closed on the shell 1, it is used to close the receiving cavity 9 and to allow the product pressing block 6 to be embedded in the pressing block groove 5, so as to push the product to be coated into the receiving groove 4.
[0030] Specifically, taking the coating process of this product as an example, firstly, the shell cover 2 is manually opened, and the part of the product that does not need to be coated is put into the receiving cavity 9. The product is then inserted into the receiving groove 4, which divides the product into two parts: the part inside the shell 1 that does not need to be coated, and the part outside the shell 1 that needs to be coated. Then, the shell cover 2 is manually closed, and the shell cover 2 and the shell 1 are closed together by the connector 3. The shell cover 2 drives the product pressing block 6 on the shell cover 2 to be embedded in the pressing block groove 5, thereby squeezing the product to be coated to a certain extent. In this way, the friction between the product to be coated and the medical coating fixture shell can prevent the product to be coated from falling off the receiving groove 4. Then, the coating machine 8 can coat, irradiate with ultraviolet light, and bake at high temperature on the part of the product to be coated. During this process, since the part of the product to be coated is inside the medical coating fixture shell, that is, inside the receiving cavity 9, the part of the product to be coated will not be coated or irradiated with ultraviolet light or baked at high temperature under the protection of the medical coating fixture shell.
[0031] Therefore, the medical coating fixture shell in the above embodiment includes a shell 1 and a shell cover 2; the shell 1 is provided with a receiving cavity 9 and a receiving groove 4, one end of the receiving groove 4 is connected to the receiving cavity 9 and the other end penetrates through the side wall of the shell 1, the receiving groove 4 is used to position the product to be coated, the receiving cavity 9 is used to accommodate the part of the product to be coated that does not need to be coated, and the part of the product to be coated that needs to be coated is located outside the shell 1; the receiving groove 4 is also provided with a pressing block groove 5, the pressing block groove 5 and the receiving groove 4 have an intersecting area, and the shell cover 2 is also provided with a product pressing block 6, the product pressing block 6 and the pressing block groove 5 are positioned corresponding to each other; after the shell cover 2 is closed on the shell 1, it is used to close the receiving cavity 9 and to make the product pressing block 6 embedded in the pressing block groove 5, so as to push the product to be coated into the receiving groove 4. When coating a product, the uncoated portion can be fixed inside the medical coating fixture shell. This way, the portion inside the medical coating fixture shell not only doesn't need to be coated, but the medical coating fixture shell also protects that portion from ultraviolet radiation or high-temperature baking, thus increasing the product yield while partially coating the product.
[0032] Optionally, the housing cover 2 is fitted onto the housing 1 via a connector; the connector 3 includes, but is not limited to, a magnetic chuck, a hinge, and a nut.
[0033] Preferably, one side of the housing cover 2 can be connected to the housing 1 via a hinge, and the other side of the housing cover 2 can be magnetically attached to the housing 1, thereby increasing the convenience of opening and closing the housing cover 2.
[0034] Optionally, the depth difference between the receiving groove 4 and the pressing block groove 5 is less than the diameter of the product to be coated.
[0035] Specifically, since the pressure block groove 5 is set on the receiving groove 4, the depth difference between the receiving groove 4 and the pressure block groove 5 is less than the diameter of the product to be coated. This allows a part of the product to be coated to be placed in the pressure block groove 5 when the product to be coated passes through the receiving groove 4. At this time, the product pressure block 6 will be inserted into the pressure block groove 5 to squeeze the product to be coated, thereby generating friction and preventing the product to be coated from falling off the receiving groove 4.
[0036] Optionally, the top of the housing 1 is provided with a fixture hanger 7; the fixture hanger 7 is used to suspend the medical coating fixture housing on the coating machine 8.
[0037] Optionally, a Luer connector 8 is also provided inside the housing 1; the Luer connector 8 is used to fix the product to be coated.
[0038] Specifically, the Luer connector 8 can be used to fix products such as endoscopes and multi-lumen medical rubber catheters.
[0039] Optionally, the housing 1 is concave, and when the housing cover 2 is attached to the housing 1, the concave part of the housing 1 and the housing cover 2 form the receiving cavity 9.
[0040] Optionally, the top of the receiving cavity 9 is provided with a positioning structure; the positioning structure is used to position the uncoated portion of the product to be coated.
[0041] Optionally, the width of the receiving cavity 9 is greater than the bending diameter of the product to be coated, in order to prevent damage to the product during the receiving process.
[0042] Optionally, the volume of the receiving cavity is larger than the volume of the product to be coated. Since the product to be coated can be a core wire, mandrel, endoscope, tubing, etc., these items are relatively long and flexible. When the portion to be coated is small, most of the product to be coated needs to be placed in the receiving cavity 9. In this case, the portion of the product to be coated that does not need to be coated needs to be coiled up and placed in the receiving cavity 9. The volume of the receiving cavity 9 is larger than the volume of the product to be coated, which can ensure that the receiving cavity 9 can completely accommodate the portion of the product to be coated, greatly increasing the versatility of medical coating fixture shells.
[0043] Optionally, the receiving cavity 9 has a slope or arc surface near the receiving groove 4, so that the width of the receiving cavity 9 gradually decreases. This arrangement allows for a smooth transition of the product to be coated inside and outside the receiving cavity 9 without damaging the product.
[0044] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0045] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
