For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; "linking" can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0033] In the description of this application, the technical terms "upper", "lower", "front", "rear", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments of this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application.

[0034] In order to better understand the above-mentioned objectives, technical solutions and advantages of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings, so as to understand in detail how to solve the problems raised in the background art.

[0035] It should be noted that the airbag structure in this embodiment is sealed at one end and open at the other. The open end of the airbag is integrally connected to the silicone tube using the heat-sealing device of this application (e.g., Figure 1 As shown in the figure, the connection between the airbag and the silicone tube is sealed and waterproof. Before processing, the airbag and the silicone tube can be inserted together to facilitate subsequent processing. The length of the silicone tube is 100mm, which makes it easy to insert or remove the two after they are connected.

[0036] like Figures 1 to 6As shown, a medical airbag heat sealing device is used to seal the connection between a single-opening airbag and a silicone tube. The heat sealing device includes a base plate 1, on which a transmission component 2, a clamping component 3, a hot air component 5, and a side pressure component 4 are provided. The base plate 1 can fix the heat sealing device to a platform or other equipment.

[0037] The transmission component 2 includes two fixed plates 21 symmetrically distributed above the base plate 1 and two belt drives 22 fixed to the back of the fixed plates 21. The two belt drives 22 are connected to a handle 6. Specifically, the fixed plate 21 is a rectangular plate, and the fixed plate 21 is fixedly connected to the base plate 1. There is a gap between the two base plates 1. The back of the fixed plate 21 is the side away from the hot air component 5 or the side pressure component 4. During processing, the two belt drives 22 can be driven to rotate synchronously by rotating the handle 6.

[0038] The clamping component 3 includes two clamping blocks 31 and a rotating rod 32 fixedly connected to the two clamping blocks 31 respectively. The clamping blocks 31 are provided with clamping channels 311, and the rotating rod 32 is provided with a channel 321. The clamping channels 311 and the channel 321 are arranged on the same axis. The rotating rod 32 is located on the front of the fixed plate 21 and passes through the fixed plate 21 and is fixedly connected to the belt drive 22 so that the belt drive 22 drives the clamping blocks 31 to rotate. Specifically, the two clamping blocks 31 are arranged facing each other with a gap between them. The connection between the airbag and the silicone tube is located at this gap. One clamping block 31 clamps the airbag, and the other clamping block 31 clamps the silicone tube. The front of the fixed plate 21 is the side closest to the hot air component 5 or the side pressure component 4. The diameter of the channel 321 is larger than the diameter of the clamping channels 311 to ensure the rapid passage of the airbag and the silicone tube. When the clamping blocks 31 rotate, they can drive the connection to rotate to ensure comprehensive and uniform heating.

[0039] Both the side pressure component 4 and the hot air component 5 are located on the side between the two clamping blocks 31, with the hot air component 5 positioned above the side pressure component 4. Specifically, both the side pressure component 4 and the hot air component 5 are located on the side of the connection. The hot air component 5 is used to heat the connection and blow out hot air. At the same time, the side pressure component 4 can apply pressure to the side wall of the connection when it is heated. The clamping block 31 drives the connection to rotate, which ensures uniform pressure and thus achieves the sealing of the airbag and the silicone tube.

[0040] The above solution can meet the sealing connection requirements of the one-way opening end of the medical airbag, and the heat sealing device has a simple structure and low cost.

[0041] like Figure 2 and Figure 3As shown, in one specific embodiment of the improvement, the belt drive 22 includes two fixed blocks 221 that are fixed to the fixed plate 21 and distributed opposite each other, a synchronous pulley 222 disposed on the fixed block 221, and a synchronous belt 223 sleeved with the synchronous pulley 222. The rotating rod 32 is rotatably connected to the fixed block 221, and the rotating rod 32 is fixedly connected to the synchronous pulley 222. Specifically, belt drives 22 are provided on the back of both fixed plates 21. Fixed blocks 221 have placement slots, and both placement slots accommodate synchronous pulleys 222. The two fixed blocks 221 are fixedly installed on the upper and lower parts of the back of the fixed plates 21. Bearings are provided on both sides of the fixed blocks 221 corresponding to the synchronous pulleys 222. The two synchronous pulleys 222 and the synchronous belt 223 form a transmission structure. The fixed plates 21 have through holes corresponding to the rotating rod 32, so that the rotating rod 32 passes through the front of the fixed plates 21 and is fixedly connected to the upper synchronous pulley 222. At this time, the end of the rotating rod 32 is rotatably connected to the bearing on the fixed block 221. Based on this, when the lower synchronous pulley 222 rotates, it can drive the upper synchronous pulley 222, thereby driving the rotation of the rotating rod 32 to ensure the linkage between the linkage shaft 61 and the rotating rod 32.

[0042] like Figure 2 As shown, in one specific embodiment of the improvement, the handle 6 is connected to a linkage shaft 61, which is connected to two synchronous pulleys 222 at the lower part of the fixed plate 21. The linkage shaft 61 is positioned below the clamping block 31. Specifically, the airbag and silicone tube enter from the belt drive 22 on the right side, and the handle 6 is positioned on the belt drive 22 on the left side. Since the fixed block 221 is equipped with bearings corresponding to the synchronous pulleys 222, the linkage shaft 61 can pass through the two fixed plates 21 and the two belt drives 22. The two ends of the linkage shaft 61 are rotatably connected to the bearings of the fixed block 221. At this time, the linkage shaft 61 and the two synchronous pulleys 222 at the lower part are fixedly connected. With the aforementioned belt drive 22, rotating the handle 6 can drive the rotating rod 32 to rotate synchronously, making the processing process easier to monitor for quality.

[0043] like Figure 2 and Figure 4As shown, in one specific embodiment of the improvement, an elastic element 34 and a pin 35 are connected between the clamping block 31 and the rotating rod 32 to allow the clamping block 31 to open or close. Specifically, both clamping blocks 31 are designed with elastic elements 34 and pins 35, forming a clamping structure. Each clamping block 31 has two interlocking jaws. The rear ends of the rotating rod 32 and the jaws are respectively provided with grooves. The elastic element 34 is accommodated in the grooves, clamping the front end of the clamping block 31. At the same time, the rotating rod 32 has multiple fixing holes near the front end of the clamping block 31, and the two jaws also have corresponding fixing holes. When the rotating rod 32 is inserted into the clamping block 31, the pin 35 passes through the fixing holes, allowing the jaws to rotate relative to the rotating rod 32. 34 is a telescopic spring. Based on this, when the two grippers are released, the clamping block 31 clamps tightly, and when the two grippers are squeezed, the clamping block 31 opens, thereby realizing the tightness of the airbag and the silicone tube. It is worth noting that a limiting rod is inserted into the channel 321 of the rotating rod 32 at the fixed end of the airbag. This limiting rod can control the insertion length of the sealing end of the airbag. At the same time, the rear end of the rotating rod 32 and the grippers are provided with multiple sets of corresponding grooves, and the rotating rod 32 is provided with multiple sets of fixing holes, so as to realize the adjustment of the initial position of the left clamping block 31, thereby realizing the adjustment of the distance between the two clamping blocks 31 to adapt to the processing of airbags of different specifications.

[0044] like Figure 2 and Figure 4 As shown, in one specific embodiment of the improvement, the clamping block 31 has a detachable adjusting block 33 at its front end for adjusting the clamping channel 311. Specifically, the clamping block 31 consists of two interlocking jaws. The front end of the jaws has a receiving groove, and the side of the front end of the jaws has a through hole. The structure of the adjusting block 33 corresponds to the receiving groove, and the adjusting block 33 also has a through hole corresponding to the aforementioned through hole. When the adjusting block 33 is inserted into the receiving groove, the jaws and the adjusting block 33 can be fixed or loosened by screws, so that the adjusting block 33 can be quickly installed and removed. The sides of the two adjusting blocks 33 have arc-shaped grooves. When the two adjusting blocks 33 are joined together, they form the clamping channel 311. The diameter of the clamping channel 311 can be adjusted by replacing different adjusting blocks 33 to accommodate the fixing of airbags and silicone tubes of different specifications.

[0045] like Figure 2 and Figure 5As shown, in one specific embodiment of the improvement, the side pressure member 4 includes a support block 41, a pressure block 42 perpendicular to the support block 41, and a pressure roller 43 rotatably connected to the pressure block 42. The support block 41 and the pressure block 42 are movably engaged, and the pressure roller 43 is disposed at the front end of the pressure block 42. Specifically, the support block 41 has a fixed seat below it, which is fixed to the base plate 1. The support block 41 has an elongated hole at its bottom, and the fixed seat has a corresponding fixed hole, which allows the support block 41 to be adjusted left and right on the fixed seat, thereby achieving the left and right adjustment of the pressure roller 43. The front end of the pressure block 42 is Y-shaped, and the pressure roller 43 is installed at the front end of the pressure block 42. The pressure roller 43 has a bearing at its center, which allows the pressure roller 43 to rotate. The top of the support block 41 has a notch for the pressure block 42 to be movably engaged, allowing the pressure block 42 to extend and retract relative to the support block 41. When the pressure roller 43 is in contact with the connection between the airbag and the silicone tube, it applies rolling pressure to ensure the seal at the connection. At the same time, the extension and retraction of the pressure block 42 can drive the pressure roller 43 to adjust back and forth to ensure the sealing quality.

[0046] like Figure 2 and Figure 5 As shown, in one specific embodiment of the improvement, an adjusting head 44 is connected to the rear end of the pressure block 42. The adjusting head 44 is fixed to the support block 41, allowing the pressure block 42 to be adjusted back and forth relative to the support block 41. Specifically, the adjusting head 44 is a side-pressure adjustable micrometer head. The adjusting head 44 can be fixed to the top right side of the support block 41. By adjusting the adjusting head 44, the pressure block 42 can be finely adjusted back and forth, achieving precise control and pressure adjustment of the pressure roller 43 to ensure sealing effect and quality.

[0047] like Figure 2 and Figure 6 As shown, in one specific embodiment of the improvement, the hot air component 5 includes a bracket 51 and a hot air duct 52 disposed at the front end of the bracket 51, with the hot air duct 52 facing the connection point. Specifically, the bracket 51 is fixed above the base plate 1, and the hot air duct 52 is used to blow hot air to the connection point of the airbag and the silicone tube for welding. To ensure concentrated heat sealing, a guide sleeve can be fitted at the front end of the hot air duct 52 to ensure sealing efficiency.

[0048] like Figure 2 and Figure 6As shown, in one specific embodiment of the improvement, the bracket 51 includes a first fixing rod 511, a first locking block 512 connected to the first fixing rod 511, and a second fixing rod 513 fixedly connected to the first locking block 512. The first fixing rod 511 and the second fixing rod 513 are perpendicular to each other. The first locking block 512 is used for adjusting the hot air duct 52 up and down. Specifically, both the first fixing rod 511 and the second fixing rod 513 are cylindrical rods. The first fixing rod 511 is fixed to the base plate 1. The first locking block 512 is provided with two through holes and a gap communicating with the through holes. The first locking block 512 at the gap has multiple fixing holes. The first fixing rod 511 and the second fixing rod 513 can pass through the through holes. Screws are installed on the fixing holes to clamp the first fixing rod 511 and the second fixing rod 513. Thus, by adjusting the tightness of the screws, the installation position of the first locking block 512 on the first fixing rod 511 can be adjusted, thereby driving the hot air duct 52 to adjust up and down to change the set height, so as to ensure accurate heating at the connection. After the adjustment is completed, the screws can be tightened.

[0049] like Figure 2 and Figure 6 As shown, in one specific embodiment of the improvement, the bracket 51 further includes a second locking block 514 and a third fixing rod 515 fixedly connected to the second locking block 514. The third fixing rod 515 is engaged with the hot air duct 52. The second locking block 514 is connected to the second fixing rod 513. The second locking block 514 is used for left-right and angle adjustment of the hot air duct 52. Specifically, the second locking block 514 and the first locking block 512 have the same structure. The two ends of the second fixing rod 513 are connected to the first locking block 512 and the second locking block 514 respectively. The front end of the third fixing rod 515 has a fixing block 221, which can be used to fix the hot air tube 52. The second fixing rod 513 and the third fixing rod 515 are perpendicular to each other. Therefore, when the screw of the second locking block 514 corresponding to the second fixing block 221 is loosened, the second locking block 514 can move left and right and rotate relative to the second fixing rod 513, thereby driving the heat sealing tube to move and change the tilt angle to ensure accurate heating at the connection. After the adjustment is completed, the screw can be tightened.

[0050] Workflow:

[0051] 1- First, connect the open end of the airbag to the silicone tube;

[0052] 2- After the connection is completed, the sealing end of the airbag enters from the channel 321 of the right rotating rod 32 until it reaches the channel 321 of the left rotating rod 32, fixing the airbag to the left clamping block 31, fixing the silicone tube to the right clamping block 31, placing the connector between the two clamping blocks 31, and placing the side pressure component 4 and the hot air component 5 on the side between the two clamping blocks 31.

[0053] 3. Adjust and turn on the hot air tube 52, and blow constant temperature hot air from the hot air tube 52 toward the connection point;

[0054] 4. Adjust the pressure roller 43 to face and be close to the connection point;

[0055] 5- Rotate handle 6 to make clamp 31 drive the connection to rotate, so that the connection is heated evenly and comprehensively. The connection and pressure roller 43 are in contact and rotated and squeezed. During the rotation, the pressure roller 43 can be finely adjusted by adjusting head 44 to make adjusting head 44 continuously close to the connection until the connection is sealed and waterproof.

[0056] 6. After the heat sealing of the connection is completed, the pressure roller 43 moves back, the clamping block 31 opens, and the processed airbag is taken out. This operation can be repeated.
