Description

Technical Field

[0001] This utility model relates to the field of bioengineering equipment technology, specifically a high-frequency heat sealing machine. Background Technology

[0002] Currently, blood banks, hospitals, and companies in the biopharmaceutical industry generally use disposable plastic bags to collect and store blood, blood products, and saline solution. High-frequency heat sealing machines, also known as high-frequency plastic adhesive welding machines, are commonly used for sealing infusion tubing in plastic bags. The infusion tubing is polarized and heated under the influence of the high-frequency electric field between the heat sealing heads of the machine, and then bonded under certain pressure. This method is characterized by being pollution-free, not damaging the liquid quality, and providing a reliable, leak-proof seal. Traditional heat sealing machines have their heat sealing heads fixed to the casing, requiring the infusion tubing to be placed inside the heat sealing head during use, resulting in poor flexibility. Existing technologies, such as the patent with publication number CN210553068U, disclose a novel high-frequency heat sealing machine... The high-frequency heat sealing machine includes a housing and a wire connected to the housing at one end. A heat sealer is installed at the end of the wire away from the housing. The wire, housing, and heat sealer are detachably connected. The heat sealer is equipped with a hand-held heat sealing handle, allowing for the replacement of different heat sealers for different sealing openings. The wire connection method allows the heat sealer to be used in a position away from the housing, improving flexibility. However, the above solution has the following drawbacks: When one person operates the heat sealing machine to heat seal an infusion tube, one hand needs to hold the heat sealing handle and the other hand needs to hold the infusion tube. The heat sealing process usually takes several seconds. Since the infusion tube is relatively soft, holding it with one hand may cause the infusion tube to shake, thus affecting the heat sealing effect. Utility Model Content

[0003] To address the shortcomings of existing technologies, the technical problem solved by this utility model is to provide a high-frequency heat sealing machine that solves the problem of material shaking during the use of existing heat sealing machines.

[0004] To solve the above problems, the technical solution adopted by this utility model is: a high-frequency heat sealing machine, including a housing, a heat sealer, wires, and a support. The housing and the heat sealer are detachably connected by wires. The heat sealer includes a heat sealing head and a hand-held heat sealing handle. The support is set separately from the housing and the heat sealer. The support includes a base, a column, and an elastic clamp. The column is set on the base and is shaped like a "7". The upper end of the column has a groove. An arc-shaped elastic clamp is set above the column. The concave arc surface of the elastic clamp abuts against the column and clamps the infusion tube. There are two columns, which are set alternately on the base.

[0005] Furthermore, the elastic clip is made of plastic or stainless steel.

[0006] Furthermore, the cross-section of the groove is an arc that is half a full circle, and the radius of the groove is consistent with that of the infusion tube.

[0007] Furthermore, the elastic clip is installed on the top of the column by screws, and an adjusting washer is provided between the elastic clip and the column.

[0008] Furthermore, the elastic clip has a small arc at the position corresponding to the groove, which is a quarter circle, and the radius of the small arc is larger than the radius of the groove.

[0009] Furthermore, the base is made of metal.

[0010] Furthermore, the column has a chamfer on the side near the free end of the elastic clip, forming an opening between it and the elastic clip.

[0011] The beneficial effects of this solution are as follows: Compared with the prior art, the high-frequency heat sealing machine of this utility model clamps the infusion tube with a movable bracket, which makes the position of the heat sealing part of the infusion tube stable and avoids the infusion tube shaking during heat sealing. When using the heat sealer for heat sealing operation, there is no need to hold the infusion tube by hand, which improves the flexibility of the heat sealing machine and enhances the heat sealing effect.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Implementation, for example, attached Figures 1 to 3As shown: A high-frequency heat sealing machine includes a housing 1, a heat sealer 2, a wire 3, and a support 4. The housing 1 and the heat sealer 2 are detachably connected via the wire 3. The heat sealer 2 includes a heat sealing head and a hand-held heat sealing handle. The specific devices and functions inside the housing 1 and the heat sealer 2 are existing technologies and will not be described in detail here. The support 4 is separately arranged from the housing 1 and the heat sealer 2 and is used to clamp the infusion tube, facilitating the movement of the support 4 to stably clamp the infusion tube at different positions. The support 4 includes a base 41 and a column 42. The support column 42 is mounted on the base 41 and has an elastic clip 43. The support column 42 is shaped like a "7". The upper end of the support column 42 has a groove 421 for positioning the infusion tube. An arc-shaped elastic clip 43 is provided above the support column 42. The concave arc surface of the elastic clip 43 abuts against the support column 42. The elastic clip 43 clamps the infusion tube, making the position of the infusion tube stable. There are two supports 42, which are spaced apart on the base 41 to facilitate the heat sealer 2 to heat seal the infusion tube between the supports 42.

[0018] The elastic clip 43 can be made of plastic or stainless steel, offering good elasticity and low cost. The groove 421 has a cross-section of a half-circle arc, with its radius matching that of the infusion tube. This accommodates the infusion tube while ensuring effective positioning. The groove 421 is rounded at the connection point with the upper surface of the column 42 to prevent damage to the infusion tube. The elastic clip 43 is mounted on top of the column 42 using screws 44. An adjusting washer 45 is provided between the elastic clip 43 and the column 42, allowing the thickness of the adjusting washer 45 to be adjusted relative to the elastic clip 43 as needed. The height of the column 42 is adjusted to control the clamping force. The elastic clip 43 has a small arc 431, which is a quarter circle, corresponding to the groove 421. The radius of the small arc 431 is larger than the radius of the groove 421. When the infusion tube is clamped, it may deform to a certain extent, leaving room for the infusion tube and ensuring clamping stability. The base 41 is made of metal, such as stainless steel plate, to ensure the overall stability of the bracket 4. The column 42 has a chamfer 422 on the side near the free end of the elastic clip 43, forming an opening between it and the elastic clip 43 to facilitate the placement of the infusion tube.

[0019] The specific implementation process is as follows:

[0020] In use, place the infusion tube 5 flat at the opening between the upper end face of the two uprights 42 and the elastic clip 43, so that the part to be heat-sealed is between the two uprights 42. Move the infusion tube 5 towards the groove 421. During the movement, the elastic clip 43 is automatically lifted upward by the pressure of the infusion tube 5. When it moves into the groove 421, release it. At this time, the infusion tube 5 is limited by the groove 421. The infusion tube 5 is stabilized in the groove 421 by the downward pressure of the elastic clip 43. Use the heat sealer 2 to heat seal the infusion tube 5. After heat sealing, gently lift the elastic clip 43 to remove the infusion tube 5. The infusion tube 5 will not shake during the heat sealing process. The heat sealing effect is good, and the operation is simple and highly flexible.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model.
