[0027] First embodiment of this application:

[0028] Please see Figures 1 to 3 ,in Figure 1 This is a schematic diagram of the structure of the medical incision heat sealing machine according to the first embodiment of the present invention. Figure 2 This is a front view connection diagram of the medical incision heat sealing machine according to the first embodiment of the present invention. Figure 3 This is a top view of the medical incision heat sealing machine according to the first embodiment of the present invention. The present invention provides a medical incision heat sealing machine, including a heat sealing component 101 and a sealing incision device. The sealing incision device includes a body 102, a blood bag placement seat 103, a moving drive assembly, an incision assembly, a collection box 104, a door 105, and a handle 106. The moving drive assembly includes a moving guide rail 107, a bidirectional screw 108, and a mounting block 109. The incision assembly includes a cutting scissors 110, a guide rail 111, and a driving component. The driving component includes an electric screw 112 and a connecting slider 113.

[0029] In this embodiment, the heat-sealing component 101 includes an insulating shell and a heat-conducting surface. The heat-conducting surfaces of the two heat-sealing components 101 are arranged opposite to each other. The heating temperature of the heat-conducting surfaces of the two heat-sealing components 101 is controlled by an external controller. The two heat-sealing components 101 are moved closer to both sides of the blood bag and heated by the moving drive assembly of the sealing cut device, so as to seal the gap of the blood bag by the heat-sealing components 101.

[0030] The blood bag placement seat 103 is fixedly connected to the body 102 and located inside the body 102. The moving drive assembly is installed on the inner wall of the body 102 and connected to the heat-sealing component 101, driving the heat-sealing component 101 to move. The cutting assembly is installed on one side of the inner wall of the body 102. The collection box 104 is installed inside the body 102 and located at the bottom inner side of the body 102. The door 105 is rotatably connected to the body 102 via a hinge and is located on the front side of the body 102.The handle 106 is fixedly connected to the door body 105 and is located on one side of the door body 105. The body 102 is a cuboid structure with an inner cavity, and the lower end of the inner cavity of the body 102 is a U-shaped structure, so that the bottom of the body 102 forms a mounting surface. A circular through hole is provided in the middle of the top of the upper end of the body 102, for an external blood collection tube to be inserted into the inner cavity of the body 102 and into the blood bag at the cut for blood collection. The front end of the body 102 has a through hole that mates with the door body 105. The left end of the door body 105 is rotatably connected to the body 102 via a hinge. The door body 105 is used to seal the inner cavity of the body 102. To avoid contamination during blood bag cutting, a transparent plate is provided in the middle of the door 105 for observing the blood bag drawing progress. A handle 106 with a U-shaped structure is fixedly connected to the front right end of the door 105 for easy opening and closing. The blood bag placement seat 103 is fixedly installed on the bottom mounting surface of the machine body 102. The blood bag placement seat 103 is a cuboid structure with an upward-facing groove opening, designed to accommodate typically long and flat blood bags. The blood bag is placed vertically through the blood bag placement seat 103. The moving drive assembly... The moving drive assembly is installed on the left side of the inner wall of the body 102 and located at the upper end of the blood bag placement seat 103. It connects two heat-sealing components 101, driving them to move closer or further apart to seal the blood bag opening. The cutting assembly is installed on the rear side of the inner wall of the body 102 and located at the upper end of the rear side. The cutting blade 110 of the cutting assembly is located above the blood bag placement seat 103 and above the heat-sealing component 101. The above-ground notch of the blood bag in the blood bag placement seat 103 is cut by the installation of the cutting assembly, so that the medical cutting heat sealing machine can automatically cut the blood bag. The collection box 104 has a U-shaped structure and has a U-shaped groove with an upward opening. The collection box 104 matches the lower U-shaped end of the machine body 102. The lower front side of the machine body 102 is provided with a through hole that cooperates with the collection box 104, so as to facilitate the placement and removal of the collection box 104. The collection box 104 is used to collect the notch automatically cut from the blood bag by the cutting assembly.Therefore, when drawing blood from a blood bag and sealing it using the medical cut-and-heat-sealing machine, first open the door 105, place the blood bag into the blood bag holder 103 with the cut-and-heat-sealing notch facing upwards, then close the door 105. Next, insert the blood collection tube from the outer wall into the machine body 102 through the through-hole at the top of the machine body 102. This will automatically cut the upper part of the blood bag, and the cut will automatically fall into the collection box 104 below. Then, insert the blood collection tube downwards into the blood bag to draw blood. After blood collection, activate the moving drive assembly to simultaneously drive the two heat-sealing components 101 towards the blood bag to seal the cut-and-heat-seale. This sealing device achieves automatic blood collection by cutting and sealing the blood bag, preventing blood splashing during the cutting process and thus avoiding the risk of aerosol infection.

[0031] Secondly, the movable guide rail 107 is fixedly connected to the body 102 and is located on the left side of the inner wall of the body 102; the bidirectional screw 108 is rotatably connected to the movable guide rail 107 and passes through the movable guide rail 107; the mounting block 109 is rotatably connected to the bidirectional screw 108 and is sleeved on the outside of the bidirectional screw 108. The movable guide rail 107 is a cuboid structure with a groove, the opening of which faces the blood bag placement seat 103. The groove of the movable guide rail 107 provides installation conditions for the bidirectional screw 108 and the mounting block 109. The bidirectional screw 108 passes through the middle of the groove of the movable guide rail 107 and is fixedly connected to the rotation output shaft of the motor to achieve electric rotation. The threads at both ends of the bidirectional screw 108 have opposite directions. The inner threads of the threaded holes on the two mounting blocks 109, which are threaded onto the bidirectional screw 108, match the directions of the threads at both ends of the bidirectional screw 108. By rotating the bidirectional screw 108 clockwise or counterclockwise, the two mounting blocks 109 are driven to move closer to or further away from each other. One end of each of the two mounting blocks 109 extends into the groove of the moving guide rail 107 and matches the convex structure of the groove to restrict rotation. This allows the two mounting blocks 109 to move horizontally relative to each other within the groove of the moving guide rail 107. The heat-sealing components 101 are fixedly and oppositely mounted on the ends of the two mounting blocks 109 near the blood bag placement seat 103. The movement of the two mounting blocks 109 drives the movement of the two heat-sealing components 101. Therefore, by driving the bidirectional screw 108 to rotate via a motor, the bidirectional screw 108 drives the two mounting blocks 109 to move relative to each other within the moving guide rail 107, thereby causing the two mounting blocks 109 to move the two heat-sealing components 101, thus realizing the movement of the two heat-sealing components 101 driven by the moving drive assembly.

[0032] Meanwhile, the cutting scissors 110 are connected to the guide rail 111 through the driving component and are located above the blood bag placement seat 103; the guide rail 111 is fixedly connected to the body 102 and is located on the left side of the inner wall of the body 102; the driving component is connected to the cutting scissors 110 and drives the cutting scissors 110 to move. Both ends of the cutting scissors 110 are sharp. The cutting scissors 110 are located above the blood bag placement seat 103 and above the heat-sealed component 101. The cutting scissors 110 cut the upper end of the blood bag by moving. The guide rail 111 is a cuboid structure with a groove. The groove opening of the guide rail 111 faces the door 105. The guide rail 111 provides conditions for the installation of the driving component. The driving component connects the cutting scissors 110 and the guide rail 111. The driving component drives the cutting scissors 110 to move at the upper end of the blood bag placement seat 103. Therefore, the cutting scissors 110 move horizontally along the guide rail 111 by the driving component, so that the cutting component can cut the upper end of the blood bag placement seat 103.

[0033] Then, the electric screw 112 is rotatably connected to the guide rail 111 and passes through the guide rail 111; the connecting slider 113 is threadedly connected to the electric screw 112 and is sleeved on the outside of the electric screw 112. The electric screw 112 consists of a screw and a motor end. The electric screw 112 passes laterally through the guide rail 111 and is rotatably connected to the guide rail 111 through the motor end. Its motor end is fixedly installed on the right end of the outer side of the body 102. The rotating output shaft of its television end extends into the inner cavity of the body 102 and is fixedly connected to the screw to realize the automatic rotation of the electric screw 112. The connecting slider 113 is sleeved on the electric screw 112, and one end of the connecting slider 113 extends into the groove of the guide rail 111. The connecting slider 113 is fitted with a convex groove and has a threaded hole threaded onto the outside of the electric screw 112. The front end of the connecting slider 113 faces the front end of the guide rail 111 and is fixedly connected to one end of the cutting shear 110. Thus, the electric screw 112 rotates to drive the connecting slider 113 to move horizontally within the groove of the guide rail 111. The movement of the connecting slider 113 drives the cutting shear 110 to move, and the driving component drives the cutting shear 110 to move to achieve the cutting operation.

[0034] This invention discloses a medical incision heat sealing machine. When drawing blood from and heat-sealing a blood bag through an incision, the machine first opens the door 105, places the blood bag into the blood bag holder 103 with the incision facing upwards, then closes the door 105. The blood collection tube on the outer wall is then inserted into the machine body 102 through a through-hole at the top. The incision assembly then automatically cuts the upper part of the blood bag, and the cut piece automatically falls into the collection box 104 below. The blood collection tube is then inserted downwards into the blood bag for blood collection. After blood collection, the moving drive assembly simultaneously drives the two heat sealing components 101 to approach and seal the blood bag incision. This sealing device achieves automatic incision blood collection, preventing blood splatter during the incision process and thus avoiding the risk of aerosol infection.

[0035] Second embodiment of this application:

[0036] Based on Example 1, see [link / reference] Figure 4 , Figure 4 This is a partial connection diagram of the sealing cut device according to the second embodiment of the present invention. The sealing cut device in this embodiment also includes an ultraviolet lamp 201 and a pull rod 202.

[0037] The ultraviolet lamp 201 is fixedly connected to the collection box 104 and located on the inner wall of the collection box 104. Multiple ultraviolet lamps 201 of different lengths are fixedly installed on the front, back, left, and right sides of the inner wall of the collection box 104. An external timer connected to each ultraviolet lamp 201 periodically disinfects the openings inside the collection box 104 with ultraviolet light, further minimizing the risk of infection.

[0038] Secondly, the pull rod 202 is fixedly connected to the collection box 104 and is located on the front side of the outer wall of the collection box 104. The pull rod 202 has a U-shaped structure, and its two ends are fixedly connected to the collection box 104 respectively. The pull rod 202 facilitates the pulling of the collection box 104, making it convenient for the periodic processing and extraction of the collection box 104.

[0039] Third embodiment of this application:

[0040] Based on Example 1, see [link / reference] Figure 5 , Figure 5 This is a partial structural connection diagram of the sealing cut-out device according to the third embodiment of the present invention. The sealing cut-out device in this embodiment also includes a telescopic closing assembly. The door body 105 has a rectangular through hole 301 and a mounting groove 302. The telescopic closing assembly includes a spring 303 and a movable plate 304.

[0041] The telescopic closing assembly is installed on the door body 105; the rectangular through hole 301 is provided on the door body 105 and penetrates the door body 105; the mounting groove 302 is provided on the door body 105 and communicates with the rectangular through hole 301. The rectangular through hole 301 is located at the middle of the upper end of the transparent plate of the door body 105. The width of the rectangular through hole 301 matches the width of the movable plate 304 of the telescopic closing assembly. The rectangular through hole 301 penetrates the door body 105, facilitating the insertion of a disinfectant spray nozzle to spray disinfectant into the inner cavity of the machine body 102. The mounting groove 302 is located at the upper end of the rectangular through hole 301, and the lower end of the mounting groove 302 is connected to the rectangular through hole 301. The mounting groove 302 matches the upper end of the movable plate 304, and the mounting groove 302 provides conditions for the installation of the telescopic closing assembly. The telescopic closing assembly changes the closed state of the rectangular through hole 301, thereby achieving sealing of the door body 105 and reducing the risk of infection by minimizing the disinfection opening.

[0042] Secondly, the spring 303 is fixedly connected to the door body 105 and is located in the rectangular through hole 301 of the door body 105; the movable plate 304 is fixedly connected to the spring 303 and is located at the lower end of the spring 303, and partially extends into the rectangular through hole 301. The upper end of the spring 303 is fixedly connected to the top of the mounting groove 302, and the lower end of the spring 303 is fixedly connected to the top of the movable plate 304. The top of the upper end of the movable plate 304 is rectangular and matches the cross-section of the mounting groove 302. The front side of the movable plate 304 is an inclined surface, so that the nozzle end of the disinfectant spray bottle approaches the inclined surface of the movable plate 304 and applies force forward. The movable plate 304 moves upward under force, and the spring 303 is compressed. The disinfectant spray bottle passes through the rectangular through hole 301 to spray disinfectant into the inner cavity of the machine body 102. When the disinfectant spray bottle port exits the rectangular through hole 301, the movable plate 304 seals the rectangular through hole 301 again through the rebound force of the spring 303 and the gravity of the movable plate 304. This allows the telescopic closing assembly to conveniently perform disinfection and sealing operations on the inner cavity of the machine body 102, thereby minimizing the risk of infection.
