Description

Technical Field

[0001] The patent of this invention relates to the field of medical equipment, specifically a mold for making food for esophageal stenosis expansion after esophageal cancer surgery. Background Art

[0002] Patients with esophageal cancer or esophageal lesions usually undergo resection of the cancerous or diseased esophagus, followed by anastomosis of the remaining esophagus, or by pulling the stomach up to anastomose with the good esophagus to form an anastomosis, so that the patient can regain esophageal function. After the anastomosis is restored, trauma / scars will appear, leading to anastomotic stenosis. Generally, after the patient is discharged from the hospital, the patient needs to go to the hospital regularly and for a long time for balloon dilatation (an inflatable ball is placed in the patient's mouth and placed at the anastomosis, and then the ball is inflated, and the ball expands to support / expand the anastomosis, and it needs to be maintained for 3 minutes) , in order to achieve the effect of expanding the esophageal anastomosis, and finally to achieve the effect of normal diet. However, some patients are unable to go to the hospital for balloon dilatation regularly and for a long time due to the inconvenience of going back and forth to the hospital, resulting in the inability of the esophageal anastomosis to expand and recover normally. Moreover, due to the stenosis of the anastomosis, patients will maintain a state of eating liquid food for a long time, causing the esophageal anastomosis to further shrink and become narrow, and eventually evolve to only be able to eat liquid food. In order to solve the above problems, we have invented a production mold that can provide patients with esophageal stenosis after esophageal cancer surgery. It can be used to support / expand the anastomosis and make expanded food.

[0024] The present invention is further described below in conjunction with the accompanying drawings.

[0025] Embodiment 1

[0026] like Figure 1-2As shown, embodiment 1 discloses a mold for making food for esophageal stenosis and swelling after esophageal cancer surgery, comprising: two cross-arranged mold halves, the two mold halves have the same structure, the mold halves include a splint 1, a rotating shaft 2 and a handle 3 connected in sequence, the rotating shafts 3 of the two mold halves fit each other, the two rotating shafts 3 are hinged by a pin, a plurality of molded units for accommodating food are arranged at equal intervals between the two splints 1 from the rotating shaft 2 to the end of the splint 1, the inner diameters of the plurality of molded units increase in sequence from the rotating shaft 2 to the end of the splint 1, the molded units include molded grooves 4 symmetrically arranged on the inner walls on the opposite sides of the two splints 1, and the molded grooves 4 are hemispherical.

[0027] Based on the above structure, Figure 1-2 As shown, the initial state is that the two splints 3 are separated from each other. When in use, the patient places an appropriate amount of steamed buns or bread in the lower molded groove 4 with the corresponding inner diameter according to the doctor's advice, and then presses the handle 3 to make the ends of the two handles 3 move relatively. Due to the lever effect, the two splints 1 approach each other until the opposite sides of the two splints 1 are completely closed. In this process, the movement of the two splints 1 applies pressure to the outer surface of the steamed buns or bread in the molded groove 4, changing the original density of the steamed buns or bread, and then changing the hardness of the steamed buns or bread. At the same time, after the two splints 1 are completely closed, the molding unit shapes the steamed buns or bread, thereby squeezing the steamed buns or bread into a spherical shape to facilitate the patient's swallowing. The patient swallows with a certain amount of water (without chewing when swallowing). The squeezed steamed buns or bread absorb water and swell during the swallowing process, and when passing through the anastomosis, the anastomosis is supported / expanded. The above swallowing needs to be carried out continuously, so as to achieve the effect of supporting / expanding the anastomosis for a long time.

[0028] When the volume of the steamed bun or bread after squeezing exceeds the patient's tolerance, the patient can also choose to swallow a small amount, for example: biting off 1-5 / 10 of the steamed bun or bread after squeezing.

[0029] Further, such as Figure 1 As shown, the top of the upper splint 1 is provided with a plurality of first filling holes 11, which are equal in number and correspond in position to the plurality of molding units respectively. The inner wall of the first filling hole 11 is connected with the inner wall of the molding unit corresponding in position. When the density / hardness of the steamed bun or bread in the molding unit needs to be increased, the steamed bun or bread can be broken into small petals and placed at the input end of the first filling hole 11. Then, a rod-shaped object (for example, chopsticks) with an outer diameter smaller than the inner diameter of the first filling hole 11 is used to press the steamed bun petals or bread petals into the molding unit through the first filling hole 11. The volume of the steamed bun or bread in the molding unit remains unchanged, but the mass increases, and the density / hardness also increases accordingly.

[0030] Further, such as Figure 1As shown, in order to prevent the steamed bun petals or bread petals from loosening during the pressing process through the first filling hole, two mounting holes for the hexagon socket bolts to pass through are symmetrically arranged on the outer walls of both sides of the upper splint 1 located on both sides of the molded groove 4, and a plurality of threaded holes with the same number and corresponding positions as the mounting holes are arranged on the inner wall of the lower splint 1, and the threaded holes are used for threaded connection with the hexagon socket bolts. After the two splints 1 are closed, the hexagon socket bolts are inserted into the mounting holes on both sides of the molded unit filled with steamed buns or bread, and the hexagon socket bolts are screwed to the threaded holes. The hexagon socket bolts limit the closure between the two splints 1, thereby preventing the two splints 1 from opening during filling.

[0031] Embodiment 2

[0032] like Figure 3-6 As shown, in order to prevent the steamed buns or bread from being squeezed out of the first filling hole due to pressure during the molding process, and to facilitate the transportation of the steamed buns or bread to the molding unit, the technical features of the second embodiment different from the first embodiment are: a mounting groove 12 is arranged at the top of the clamping plate 1 located above the first filling hole 11, and two slide grooves 13 are symmetrically arranged at the bottom end of the mounting groove 12, and both opposite sides of the slide grooves 13 are connected to the first filling hole 11. A pressure spring 131 and a sealing block 132 are installed in the slide groove 13, and the two ends of the pressure spring 131 are respectively connected to the inner wall of the slide groove 13 and the end of the sealing block 132. The two sealing blocks 132 are in contact with each other, one end of the sealing block 132 away from the pressure spring 131 extends into the first filling hole 11, and the opposite sides of the two sealing blocks 132 are fitted together. A pressure block 14 covering the slide groove 13 is installed in the mounting groove 12, and the pressure block 14 is fixed to the clamping plate 1 by multiple screws. The top of the pressure block 14 is provided with a second filling hole 141 connected to the first filling hole 11. The outer walls of the sealing blocks 132 are respectively fitted and slidably connected with the inner wall of the slide groove 13 and the bottom end of the pressure block 14, and the tops of the two sealing blocks 132 located in the second filling hole 141 are both inclined from outside to inside and downward.

[0033] Based on the above structure, Figure 3-5 As shown, when the two clamping plates 1 are closed, the steamed buns or bread are pressed and extruded toward the first filling hole 11. When the extruded steamed buns or bread contact the bottom end of the sealing block 132, the sealing block 132 generates an upward thrust, and the screw connection between the pressing block 14 and the upper clamping plate 1 provides a reaction force for the sealing block 132, thereby preventing the steamed buns or bread from being extruded from the first filling hole 11.

[0034] When it is necessary to fill steamed buns or bread, first place the steamed bun petals or bread petals at the output end of the second filling hole 141, and then press the steamed bun petals or bread petals into the second filling hole 141 through a rod-shaped object until the bottom ends of the steamed bun petals or bread petals abut against the top ends of the two sealing blocks 132, and then continue to press down through the rod-shaped object, and the downward pressure acts on the top ends of the sealing blocks 132 in the second filling hole 141 through the steamed bun petals or bread petals. Since the top ends of the sealing blocks 132 are inclined, when pressure acts on the top ends of the sealing blocks 132, the top-down pressure on the two sealing blocks 132 will be changed into a driving force for the two sealing blocks 132 to move to opposite sides, and the sealing blocks 132 will shrink into the slide groove 13 on the corresponding side, and the rod-shaped object will continue to press down the steamed bun petals or bread petals until the rod-shaped object and the steamed bun petals or bread petals pass through between the two sealing blocks 132, and press the steamed bun petals or bread petals into the molding unit through the first filling hole 11;

[0035] When the sealing block 132 is retracted to the slide groove 13, the pressure spring 131 is compressed and retracted. When the rod-shaped object is pulled out, the pressure spring 131 rebounds and pushes the sealing block 132 to move toward the first filling hole 11 until the opposite sides of the two sealing blocks 132 abut against each other.

[0036] Further, such as Figure 4-5 As shown, in order to avoid the sealing block 132 from extending excessively, so that the opposite side of the two sealing blocks cannot correspond to the center of the first filling hole, and then the steamed bun petals or bread petals cannot be filled through between the two sealing blocks, the upper part of the inner walls on both sides of the slide groove 13 is symmetrically provided with two limit grooves 133 whose inner walls are connected to the inner wall of the installation groove 12, and the limit block 134 integrally arranged with the side wall of the sealing block 132 is slidably connected in the limit groove 133. When the pressure spring 131 rebounds and pushes the sealing block 132 to slide, the limit block 134 slides along the limit groove 133 until the limit block 134 abuts against one end of the limit groove 133 close to the first filling hole 11, and the opposite sides of the two sealing blocks 132 abut and correspond to the center of the first filling hole 11.

[0037] Further, such as Figure 3-4 As shown, in order to facilitate the entry of the steamed bun petals or the bread petals into the second filling hole, a filling hole 142 with an inner diameter that gradually decreases from top to bottom is provided at the top of the pressing block 14, the filling hole 142 is connected to the second filling hole 141, and the center of the filling hole 142 corresponds to the center of the second filling hole 141. When the steamed bun petals or the bread petals are placed in the filling hole 142, since the inner diameter of the filling hole 142 gradually decreases from top to bottom, the steamed bun petals or the bread petals move toward the entrance end of the second filling hole 141 along the inclined setting of the inner wall of the filling hole 142.

[0038] Further, such as Figure 3-4As shown, in order to facilitate real-time detection of the hardness of the steamed buns or bread in the molding unit, a hardness tester 5 is also included. The hardness tester 5 includes a main body 51 installed on the outer wall of the upper clamping plate 1 and an impact pen 52 connected to the main body 51 through a harness. The outer wall of the lower clamping plate 1 is provided with a plurality of connection grooves 15, which are equal in number and corresponding in position to the plurality of molding units. The top of the inner wall of the connection groove 15 is provided with a through hole 151 for the impact pen 52 to extend into the molding unit. The outer wall of the impact pen 52 is threadedly connected to the inner wall of the connection groove 15. When in use, the impact pen 52 is screwed to the corresponding connection groove 15. The execution end of the impact pen 52 detects the hardness of the steamed bun or bread in the molded unit in real time during and after the closing of the two splints 1, and feeds back to the main body 51 for display together with the wiring harness, so as to facilitate the patient to determine whether the hardness of the steamed bun or bread in the molded unit meets the standard (if the hardness is too high, the steamed bun or bread cannot fully absorb water to expand; if the hardness is too low, the steamed bun or bread will decompose quickly and cannot support / expand the anastomosis).

[0039] Embodiment 3

[0040] like Figure 7 As shown, in order to avoid the insulating material on the surface of the wiring harness from cracking due to the long-term rotation of the impact pen, the technical feature that distinguishes the third embodiment from the second embodiment is that the outer wall of the impact pen 52 is fitted and slidably connected to the inner wall of the connecting groove 15, and a mounting cylinder 152 is provided at the bottom end of the lower clamping plate 1 located at the end of the connecting groove 15, and a thread is provided on the outer wall of the impact pen 52, and a rotating cylinder 521 is threadedly connected, and a connecting ring 522 is integrally provided at the top of the rotating cylinder 521, and a connecting cover 523 is sleeved and rotatably connected on the outer wall of the connecting ring 522, the bottom end of the connecting cover 523 is fitted and slidably connected to the top of the rotating cylinder 521, the inner wall of the connecting cover 523 is threadedly connected to the outer wall of the mounting cylinder 152, and a limiting ring 524 is installed on the top of the connecting ring 522 by multiple screws, and a receiving groove 525 for accommodating the limiting ring 524 is provided at the bottom end of the inner wall of the connecting cover 523, and the outer wall of the limiting ring 524 is fitted and rotatably connected to the inner wall of the receiving groove 525.

[0041] Based on the above structure, Figure 7As shown, when the impact pen 52 needs to be inserted into the molding unit, the rotating cylinder 521 is first rotated to adjust the position of the rotating cylinder 521 and the connecting cover 523 on the impact pen 52 until the length between the lower end of the inner wall of the connecting cover 523 and the executing end of the impact pen 52 is equal to the length between the lower end of the mounting cylinder 152 and the top of the inner wall of the connecting groove 15, and then the executing end of the impact pen 52 is inserted from the mounting cylinder 152 into the connecting groove 15 until the connecting cover 523 covers the box to the mounting cylinder. 152 lower end, then rotate the connecting cover 523 to screw the connecting cover 523 and the mounting tube 152. During the screwing process of the connecting cover 523, the impact pen 52 is driven to move toward the through hole 151 through the limiting ring 524, the connecting ring 522 and the rotating tube 521 in turn. When the connecting cover 523 is screwed to the mounting tube 152, the end of the connecting groove 15 abuts against the top of the inner wall of the connecting groove 15, and the execution end of the connecting groove 15 passes through the through hole 151 and extends into the molded unit.

[0042] Preferably, Figure 8 As shown, the molded groove 4 is in a semi-teardrop shape / semi-ellipse shape / semi-rhombus shape / semi-rectangle shape, and the corners of the semi-rhombus shape / semi-rectangle shape are arc-shaped.

[0043] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and invention concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
