Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a device for curing a medical catheter seat. Background Art

[0002] The balloon dilatation catheter is a medical device. During production, a glue dispenser and a curing machine are required between the catheter and the catheter seat to bond the Y-shaped catheter seat to the double-lumen tube. The curing machines on the market can only cure the glue by emitting UV light. The equipment has no support seat. In the existing production process, after dispensing the glue, the operator can only hold the double-lumen tube and the Y-shaped catheter seat by hand for UV light curing. Due to the large light beam area, the irradiation position cannot be stabilized in one position each time, and the irradiation cannot be uniform. In addition, it is necessary to observe and rotate the catheter seat for irradiation. This method has the problem that each product is placed in a different position, resulting in inconsistent tension and appearance after the catheter bonding effect comes out, which is not suitable for mass production of products. In addition, although there is a protective cover, it cannot completely prevent UV light from irradiating the human body. UV light is harmful to the skin and eyes. Utility Model Content

[0040] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0041] Example 1

[0042] A medical catheter seat curing device, such as Figures 1 to 6 As shown, it includes a base 1, a fixing component 2, an irradiation component 3 and a light shield 4.

[0043] The fixing assembly 2 is slidably arranged on the base 1 along the length direction of the base 1, and the fixing assembly 2 has a clamping portion 22, which can clamp the catheter seat 7, so that the catheter seat 7 is fixed on the fixing assembly 2, and slides with the sliding of the fixing assembly 2. Specifically, the fixing assembly 2 includes a fixing seat 21 and a light shielding plate 24, and the fixing seat 21 is provided with a clamping portion 22, and the clamping portion 22 is preferably an elastic ring, which matches the end of the catheter seat 7. During assembly, force is applied to insert the end of the catheter seat 7 into the elastic ring. Under the elastic force of the elastic ring, the catheter seat 7 is clamped, so that it can be fixed on the fixing seat 21. The elastic ring includes but is not limited to a silicone ring and a rubber ring. Since the catheter seat 7 is mostly Y-shaped, in order to make the connection between the catheter seat 7 and the fixing seat 21 more stable, the lower end of the fixing seat 21 is also provided with a bearing portion 23 for bearing the other end of the catheter seat 7. The light shielding plate 24 can optionally have a guide wire hole 241 for the guide wire to pass through.

[0044] The fixed component 2 is slidably connected to the base 1 via a sliding mechanism 6. The sliding mechanism 6 includes a slide rail 61 provided on the base 1 and extending along the length direction of the base 1, and a slider 62 slidably provided on the slide rail 61. The fixed component 2 is fixedly connected to the slider 62, so that it can slide on the slide rail 61 driven by the slider 62. Of course, the manner in which the fixed component 2 is slidably connected to the base 1 is not limited to this, and can also be other embodiments in the art, which is not limited in this application.

[0045] The irradiation assembly 3 is fixedly mounted on the base 1, and includes a lamp holder 31 and a plurality of UV irradiation lamps 32. The lamp holder 31 has a channel 311 that runs through the lamp holder 31 along the length direction of the base 1, and a plurality of UV irradiation lamps 32 are evenly arranged in the channel 311. When the catheter seat 7 slides under the drive of the fixing assembly 2, the catheter seat 7 can pass through the channel 311, and under the irradiation of the UV irradiation lamps 32 in the channel 311, the glue in it is cured, thereby connecting the catheter seat 7 with the catheter as a whole. In order to avoid uneven curing of the glue, the channel 311 is constructed to include at least a cylindrical first part, and the UV irradiation lamps 32 are arranged in sequence around the circumference of the first part. Preferably, there are 3 to 4 UV irradiation lamps 32. In this embodiment, there are 4 UV irradiation lamps 32, that is, the angle between two adjacent UV irradiation lamps 32 and the axis of the first part is 90°.

[0046] In order to ensure that the irradiation position of each catheter seat 7 is the same, the present application also provides a first limiting member 51 for limiting the fixing assembly 2 at the curing position. Specifically, the first limiting member 51 is fixedly mounted on the base 1 and has a limiting portion 53. The fixing assembly 2 has a matching portion 54 that matches the limiting portion 53. When the matching portion 54 slides to the limiting portion 53 of the first limiting member 51, at least one injection hole of the catheter seat 7 is located in the channel 311, and the limiting portion 53 prevents the fixing assembly 2 from sliding so that the fixing assembly 2 remains in the curing position. Further, the limiting portion 53 of the first limiting member 51 has a plurality of limiting portions 53 arranged along the length direction of the base 1, and the limiting portions 53 of the plurality of first limiting members 51 correspond one-to-one to the injection holes of the catheter seat 7. When the matching portion 54 is located at the limiting portion 53 of any one of the first limiting members 51, the UV irradiation lamp 32 is directed to the outer periphery of the catheter seat 7 where the injection hole corresponding to the limiting portion 53 is located. In this embodiment, the first stopper 51 has two stopper portions 53, which are specifically grooves 11, and the left and right sides of the groove 11 have guide slopes, so that when a greater driving force is applied to the fixing component 2, the fixing component 2 can be separated from the stopper and slide. The matching portion 54 is a convex block, such as a ball screw.

[0047] The light shield 4 is hinged on the base 1 and is located outside the irradiation assembly 3. It can be opened or closed relative to the base 1. In order to facilitate opening and closing of the light shield 4, a handheld portion 41 is provided on the light shield 4 for the operator to operate to open or close. The light shield 4 has an opening 42 at one end adjacent to the irradiation assembly 3 for the passage of the fixed assembly 2, and an opening 43 matching the conduit at the other end for the passage of the conduit. When the fixed assembly 2 is in the curing position, the light shield 24 thereon is located in the light shield 4 and forms a barrier near the opening 42 of the light shield 4, thereby preventing UV light from leaking from the opening 42 and causing harm to the human body. In this embodiment, the light shield 4 has two portions disposed on the left and right sides of the irradiation assembly 3, the left and right sides of the light shield 4 close to the fixed assembly 2 respectively have openings 42, and the other side close to the irradiation assembly 3 has an opening 42 for the passage of the fixed assembly 2, that is, the left and right sides of the light shield 4 on the left side have openings 42, and the left side of the light shield 4 on the right side has an opening 42. In order not to block the catheter on the catheter seat 7 , the right side of the light shield 4 has the above-mentioned opening 43 .

[0048] In order to further prevent UV light leakage, when the light shield 4 is closed, a buffer strip 44 is provided on the base 1 and the fixing seat 21 facing the lower end thereof. The buffer strip 44 is preferably made of a soft material, so that when the light shield 4 is closed, it can play a fitting role to prevent light leakage and harm the eyes and other body parts of the operator. Of course, the buffer strip 44 can also be provided at the lower end of the light shield 4.

[0049] The base 1 has a hollow cavity, and the hollow cavity has a groove 11. The connecting wire 33 of the UV irradiation lamp 32 can be arranged in the hollow cavity through the groove 11, which is more tidy. A stopper 12 is provided on the base 1 to prevent the fixing component 2 from sliding out of the slide rail 61 and detaching from the base 1. In addition, a second limiting member 52 is also installed on the base 1. The second limiting member 52 has a limiting portion 53 that matches the matching portion 54. When the matching portion 54 is located at the limiting portion 53 of the second limiting member 52, the limiting portion 53 prevents the fixing component 2 from sliding so that the fixing component 2 remains in the initial position, so that dispensing or other operations can be performed at this position. The limiting portion 53 of the second limiting member 52 refers to the limiting portion 53 of the first limiting member 51, and will not be repeated here.

[0050] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
