[0024] In the production process of medical devices, the assembly of parts is an inevitable link. Due to processing errors in the production process, the dimensions of parts may have slight deviations. To address this situation, fasteners and the deformation of flexible bodies such as sponges are usually used to press the parts tightly during assembly. This fastening method relying on flexible materials can effectively cope with processing errors, but it also correspondingly increases the material cost.

[0025] Therefore, the present utility model proposes a cover body 2, and this cover body 2 is used to assemble the parts 3 to be assembled on the base 1. Here, the base 1 can be the housing of a medical device or any structure that needs to assemble parts.

[0026] Please refer to Figure 1 and Figure 2The cover body 2 proposed by the utility model includes a top plate and a side plate, which enclose a receiving cavity for receiving the part 3 to be assembled. An elastic arm 22 is provided on the top plate, and the elastic arm 22 is bent toward the receiving cavity. The end of the side plate away from the top plate is provided with a connecting structure, such as a snap structure or a threaded structure, etc. The cover body 2 is fixedly connected to the base 1 through the connecting structure. When the cover body 2 is connected to the base 1, the elastic arm 22 is elastically deformed by the push of the part 3 to be assembled, thereby pressing the part 3 to be assembled and the base tightly.

[0027] In this solution, the cover 2 can be made of plastic or metal and is used for fixed connection with the base 1. The connection between the cover 2 and the base 1 can be a snap connection or a threaded connection. For example, a tongue 23 is provided at one end of the side plate of the cover away from the top plate, and a slot matching the tongue 23 is provided on the base. When the cover 2 and the base 1 are connected, the tongue 23 is inserted into the slot to realize the snap connection between the cover 2 and the base. A hollow area is provided on the top plate of the cover, and an elastic arm that can undergo elastic deformation is provided in the hollow area. The elastic arm 22 is bent toward the receiving cavity.

[0028] When assembling part 3, first place part 3 on the installation position of base 1, and then buckle the cover body with base 1. During this process, the elastic arm 22 will contact and squeeze the part 3 to be assembled. The elastic arm 22 will be elastically deformed by the push of part 3, thereby generating elastic restoring force, and then the elastic restoring force of the elastic arm 22 is used to press part 3 tightly on the installation position.

[0029] In summary, the cover body 2 utilizes the natural elasticity of the elastic arm 22 to achieve a stable installation of the part to be assembled 3. Since the elastic arm 22 can automatically adjust the degree of deformation according to the processing error of the part to be assembled 3, it not only reduces the precision requirement for processing the part 3, but also eliminates the use of additional flexible parts, simplifies the operation process, and reduces material costs.

[0030] For the specific structure of the elastic arm 22, refer to Figure 2 The elastic arm 22 includes a connecting portion 221 and a contact portion 222. The connecting portion 221 is arranged in the hollow area of ​​the top plate and is integrally connected to the top plate, and the upper surface of the connecting portion 221 is flush with the upper surface of the top plate. The contact portion 222 is arranged at the free end of the connecting portion 221 and is bent toward the inside of the accommodating cavity. When the cover body 2 is connected to the base, the contact portion 222 is elastically deformed by the contact of the part 3 to be assembled, thereby pressing the part 3 to be assembled tightly against the mounting position of the base.

[0031] In one embodiment, a groove 2221 is formed on the top surface of the abutting portion 222 .

[0032] On the one hand, the groove 2221 is used to insert a rod member to lift the abutting portion 222. When it is necessary to slightly adjust the position of the part 3, tools such as fingers or rods can be inserted into the card slot to pry up the abutting portion 222, so as to release the pressing effect of the abutting portion 222 on the part 3, thereby facilitating the adjustment of the position of the part 3. In addition, referring to Figure 2 , the setting of the groove 2221 can also be adapted to the arc shape below the abutting portion 222, so that the wall thickness of the abutting portion 222 is more uniform in the length direction, so that the quality of the produced abutting portion 222 is better and more stable when the abutting portion 222 is produced by injection molding.

[0033] Define the surface of the abutting portion 222 that is in contact with the part 3 to be assembled as the abutting surface 2222. The shape of the abutting surface 2222 is the same as the shape of the contact surface of the part 3 to be assembled, so as to ensure that the abutting surface 2222 can be closely attached to the contact surface of the part 3 to be assembled, and to ensure the stability during the assembly process of the part 3. When the contact surface of the part 3 to be assembled is a plane, the abutting surface 2222 is also designed as a plane; when the contact surface of the part 3 to be assembled is a curved surface, the abutting surface 2222 is also designed as a curved surface. For example, the part 3 to be assembled can be a cylindrical part such as a one-way valve, an inductor, and a diode. At this time, the outer circumferential surface of the part is an arc surface. At this time, the abutting surface 2222 is also designed as an arc surface, and the curvature of the abutting surface 2222 is the same as the curvature of the side wall of the part 3 to be assembled. During assembly, the abutting surface 2222 can tightly surround the cylindrical part 3, thereby ensuring the stability and positioning accuracy of the part 3 during the assembly process.

[0034] In the above-described embodiment, the elastic arm 22 presses the part 3 in the circumferential direction. However, in actual application, the elastic arm 22 can also press the part 3 in the axial direction, which mainly depends on the installation direction of the part 3 and is not limited herein.

[0035] In the cover body 2, one, two, three or more elastic arms 22 can be provided. The more the number of elastic arms 22, the more pressing points of the part 3, and the more stable the assembly of the part 3. When two or more elastic arms 22 are provided, the two or more elastic arms 22 are spaced apart on the top plate, and the multiple elastic arms 22 can be arranged in the same direction on the top plate or can be arranged in opposite directions on the top plate.

[0036] For example, in Figure 2 the shown embodiment, two elastic arms 22 are provided, and the two elastic arms 22 are arranged opposite to each other and offset on the top plate. In this embodiment, the two elastic arms 22 are arranged offset and opposite to each other, which helps to more evenly distribute the fastening force, thereby avoiding the phenomenon of tilting or offset of the part 3 caused by local pressure.

[0037] The present utility model also provides a fixing assembly 100, which includes a base 1 and a cover 2. The base 1 is provided with a mounting position for placing a part 3, and the cover 2 is snapped onto the base 1 to tightly press the part 3 onto the mounting position. For the specific structure of the cover 2, reference may be made to the above embodiments. Since this fixing assembly 100 adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated herein one by one.

[0038] The present utility model also provides a medical device, which includes a housing and an infusion assembly disposed in the housing. The housing includes a fixing assembly 100, and for the specific structure of this fixing assembly 100, reference may be made to the above embodiments. Since this medical device adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated herein one by one. Among them, the infusion assembly includes an infusion pipeline and a one-way valve disposed on the infusion pipeline, and the one-way valve is fastened to the mounting position of the fixing assembly 100.

[0039] The above are only exemplary embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structural transformation made under the technical concept of the present utility model by using the content of the specification and drawings of the present utility model, or any direct / indirect application in other related technical fields, is included in the patent protection scope of the present utility model.
