Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a connecting component and medical equipment. Background Art

[0002] In the medical field, silicone and other soft rubber encapsulation are rarely used. The main reason is that silicone is too soft and can easily separate from the encapsulated parts after long-term use. Secondly, the material of the encapsulated parts is difficult to select, because metal and most plastic parts have poor adhesion to ordinary silicone. Only high-priced liquid silicone can have strong enough adhesion. Then the raw materials and mold opening costs of liquid silicone are much higher than ordinary silicone, with poor reliability and high cost, which leads to many designs abandoning the silicone encapsulation method.

[0003] However, the silicone encapsulation method has many advantages. For example, silicone encapsulated in a hard shell can make the touch softer and can also provide collision protection. Silicone encapsulated in hard shell can retain the softness of silicone while increasing the compressive strength, and can also be used as a fixed structure.

[0004] Therefore, it is necessary to overcome the problem that soft rubber encapsulation is difficult to connect with hard parts in order to apply it in the medical field. Utility Model Content

[0024] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0025] Provided is a medical device, such as a blood oximeter, a monitor, etc., which includes a connection component that can be used for connecting lines, pipelines, etc.

[0026] Among them, combined Figure 1-3The connecting component includes a soft rubber part 1, a support part 2 and a connecting part 3. The support part 2 and the connecting part 3 are both made of hard materials. The support part 2 is provided with a first assembly structure 22 and a protruding rubber positioning structure 21. The soft rubber part 1 covers the support part 2 and exposes the first assembly structure 22. The rubber positioning structure 21 is completely located in the soft rubber part 1. The connecting part 3 is provided with a second assembly structure 31 that is detachably matched with the first assembly structure 22.

[0027] In this solution, by arranging the support member 2 in the soft rubber member 1 and making the rubber positioning structure 21 completely embedded in the soft rubber member 1, the soft rubber member 1 and the support member 2 can be firmly and stably connected, and the support member 2 is provided with a first assembly structure 22, and the connecting member 3 is provided with a second assembly structure 31. Through the assembly of the first assembly structure 22 and the second assembly structure 31, the connecting member 3 and the support member 2 can be reliably connected, thereby realizing a reliable connection between the connecting member 3 and the soft rubber member 1. In this way, a reliable connection between the soft rubber and the hard structural member can be realized, the difficulty of rubber encapsulation is reduced, the versatility is strong, and the cost is reduced while the reliability is increased.

[0028] Furthermore, the rubber positioning structure 21 includes a plurality of bosses 211 arranged at intervals, and each boss 211 extends into the interior of the soft rubber part 1. During the rubber encapsulation process, the support part 2 is first positioned in the soft rubber mold, and then the silicone is formed to cover the outside of each boss 211, so that a reliable connection can be formed between the soft rubber part 1 and the hard support part 2. Although some parts of the soft rubber part 1 may not be adhered to the support part 2 after cooling and solidification, because the plurality of bosses 211 are embedded in the soft rubber part 1, the effect of preventing the support part 2 and the soft rubber part 1 from being separated can be achieved, so that the connecting part 3 can be reliably connected to the soft rubber part 1 through the support part 2.

[0029] Furthermore, the boss 211 is provided with a through hole 2111, and the material of the soft rubber part 1 is filled in the hole 2111. The soft rubber part 1 is coated on the support part 2, and the boss 211 is embedded in the soft rubber part 1. In addition, the material filled in the hole 2111 of the boss 211 is actually a part of the soft rubber part 1. The entire soft rubber part 1 is an integrated structure, which is equivalent to a part of the soft rubber part 1 being embedded in the hole 2111 of the boss 211. In this way, when the soft rubber part 1 has good elasticity, due to the limiting effect of the boss 211 and the pulling effect of the hole 2111, the support part 2 is not easy to be separated from the soft rubber part 1, which is equivalent to the soft rubber part 1 being firmly coated outside the support part 2, and the structure is reliable.

[0030] Further, the first assembly structure 22 is arranged inside the support member 2, and the glue positioning structure 21 includes bosses 211 arranged at intervals around the circumference of the support member 2. Specifically, in the present embodiment, the support member 2 is a circular ring structure, the first assembly structure 22 is located on the inner side of the support member 2, and the glue positioning structure 21 is a boss 211 arranged at intervals around the circumference of the support member 2. In this way, the bosses 211 are evenly distributed, the connection strength between the support member 2 and the soft glue structure is more balanced, and the reliability is better. Among them, the width of the boss 211 gradually increases from the support member 2 to the outside, presenting a shape with a large outer end and a small inner end, and the corner position is rounded. In this way, the boss 211 is more difficult to come out of the soft glue member 1 after being embedded in it, and the anti-detachment effect is better. Each boss 211 is provided with an opening 2111 parallel to the circumferential direction of the support member 2, so the opening 2111 is a circular hole, so that the support member 2 is not easy to be separated from the soft glue member 1 in all directions.

[0031] In some embodiments, the shape of the support member 2 can be a regular polygonal ring, such as a square, a regular pentagon, a regular hexagon, etc. In some embodiments, the shape of the boss 211 can be adaptively adjusted, such as being set to a T-shape, a Y-shape, etc. In short, shapes with a large outer end and a small inner end are all within the protection scope of this application. In some embodiments, when the volume of the boss 211 is large, a plurality of openings 2111 can be provided. In addition, the shape of the opening 2111 can also be adaptively set, such as being set to an elliptical shape, a waist shape, etc.

[0032] Furthermore, at least two circles of bosses 211 are provided on the circumferential side of the support member 2, and each circle of bosses 211 is spaced apart from each other in the axial direction. Specifically, in the present embodiment, two circles of bosses 211 are provided on the circumferential side of the support member 2, and one circle is close to the top end of the support member 2, and the other circle is close to the bottom end of the support member 2. The number and shape of the two circles of bosses 211 are the same, and they are symmetrical up and down. In this way, the support member 2 will be limited by the soft rubber member 1 in both the axial direction and the circumferential direction, and it is more difficult to separate from the soft rubber member 1. It should be understood that in some embodiments, the circumferential side of the support member 2 can be set to one circle, three circles, or four circles of bosses 211, and the bosses 211 of different circles can be staggered with each other.

[0033] Furthermore, the soft rubber part 1 can be a silicone part, the support part 2 can be a hard plastic part, a metal part or a ceramic part, etc., and the connecting part 3 can be a hard plastic part, a metal part or a ceramic part, etc. In this embodiment, the soft rubber part 1 is made of silicone material, the support part 2 is made of hard plastic, and the connecting part 3 is made of hard plastic. In this way, the soft rubber part 1 and the connecting part 3 can be reliably connected through the setting of the support part 2, and the soft rubber part 1 can be used as a part in contact with the user, which reasonably utilizes the advantage of silicone being softer to the touch and can play a role in collision protection, and the support part 2 can support the soft rubber part 1, so that the structure of the soft rubber part 1 is more stable. It should be understood that the support part 2 and the connecting part 3 can be adaptively selected according to actual conditions, as long as the material of the support part 2 can withstand the temperature when the silicone is molded. This solution can achieve the fixation of the soft rubber part 1 and the hard non-sticky material, greatly reducing the difficulty of silicone encapsulation, with strong versatility, reducing costs and increasing reliability.

[0034] Further, the first assembly structure 22 includes a through hole 221 opened in the middle of the support member 2 and a first clamping structure 222 arranged on the inner wall of the through hole 221, and the second assembly structure 31 includes a boss 311 protruding from the connection member 3 and a second clamping structure 312 arranged on the outer periphery of the boss 311, the boss 311 matches the through hole 221, and the first clamping structure 222 and the second clamping structure 312 are clamped and matched. Among them, one of the first clamping structure 222 and the second clamping structure 312 is a clamping convexity and the other is a clamping groove. In this way, the first clamping structure 222 and the second clamping structure 312 can be clamped together by only inserting the boss 311 of the connection member 3 into the through hole 221 of the support member 2, which is convenient and quick. Specifically, in this embodiment, the first snap-fit ​​structure 222 is a snap-fit ​​groove in the through hole 221, which is annular, and the second snap-fit ​​structure 312 is a snap-fit ​​protrusion on the outside of the convex column 311, which is also annular. The support member 2 is made of elastic material, so that under the action of external force, the connector 3 can be assembled or pulled out by plugging the convex column 311 and the through hole 221. It should be understood that the first snap-fit ​​structure 222 and the second snap-fit ​​structure 312 are not limited to the aforementioned methods. For example, one of the first snap-fit ​​structure 222 and the second snap-fit ​​structure 312 can be a plurality of protrusions arranged at intervals in an annular shape, and the other can be a plurality of snap-fit ​​grooves arranged at intervals in a surrounding shape, and the plurality of protrusions and the plurality of snap-fit ​​grooves are snap-fitted one by one.

[0035] Furthermore, the soft rubber part 1 includes an elastic ring 11 and a connection seat 12 connected to the outer periphery of the elastic ring 11, the thickness of the connection seat 12 is greater than the thickness of the elastic ring 11, and each connection seat 12 is covered with a support member 2, and the support member 2 is used to realize the assembly between the connection seat 12 and the connection member 3. Among them, the elastic ring 11 has good elasticity, thereby realizing the deformation function, and can be used for its own medical function, and the connection seat 12 is connected to the elastic ring 11 and has a larger thickness, and its own structural strength is higher. Further covering a support member 2 can further improve its structural strength, and can be used for assembly connection with the connection member 3. In this embodiment, a connection seat 12 is respectively provided on the opposite sides of the outer side of the elastic ring 11, and a support member 2 is provided in each connection seat 12 for connection with the connection member 3.

[0036] Furthermore, the connector 3 further includes a limiting edge 313 extending from the outer periphery of the boss 311, and the outer diameter of the limiting edge 313 is smaller than the inner diameter of the through hole 221. During the assembly of the connector 3 and the support member 2, the limiting edge 313 can abut against the end of the support member 2, so that the connector 3 can be prevented from being over-inserted, and the reliability is higher.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
