Description

Technical Field

[0001] The present invention relates to the field of medical devices, and more specifically, to an abdominal circulation hyperthermic perfusion assistance device for tumor treatment. Background Art

[0002] Abdominal circulation hyperthermic perfusion is a method for treating intra-abdominal tumors. It utilizes the difference in heat tolerance between tumor cells and normal cells. By heating therapeutic drugs and normal saline to 42 - 43 degrees and then perfusing them into the patient's abdominal cavity for constant temperature circulation, this process aims to eliminate cancer cells and micro-lesions in the abdominal cavity, thereby achieving the treatment purpose.

[0003] For example, the Chinese patent with the authorization announcement number CN115721478B discloses an abdominal circulation hyperthermic perfusion device for tumor treatment. This device is provided with a force-assisted body position transformation mechanism. Through the mutual cooperation of the annular embedded eversion component one, the annular embedded eversion component two, and the internal drive component, it can easily assist the patient to turn the body and change the body position, thereby being able to improve the convenience of the patient's treatment operation process to a certain extent;

[0004] During the actual hyperthermic perfusion treatment process, it is necessary to perfuse normal saline and therapeutic drugs into the patient's abdominal cavity through a pipeline, and recycle the excess normal saline into the host for filtration and circulation. The temperature of the normal saline and drugs will directly affect the treatment effect. The normal treatment temperature is usually controlled between 42 and 43 degrees Celsius. However, during the actual operation process, due to the temperature difference between the liquid medicine temperature and the ambient temperature, the heat of the liquid medicine will continuously volatilize during the transportation process, resulting in a decrease in the temperature of the liquid medicine entering the patient's abdominal cavity. When the temperature is lower than the optimal treatment temperature, it will affect the treatment effect. Summary of the Invention

[0040] As Figures 1 to 9 shown, an abdominal cavity circulation hyperthermic perfusion assisting device for tumor treatment provided by an embodiment of the present invention includes a body 11, a mounting plate 12 is fixedly connected to the outer surface of the left end of the body 11, the number of the mounting plates 12 is two groups and they are distributed in parallel up and down, a fixed sleeve 13 is fixedly connected between the two groups of mounting plates 12, and a heat preservation component is arranged inside the fixed sleeve 13;

[0041] The heat preservation component includes a first heating plate 19 fixedly connected to the inner surface of the fixed sleeve 13, a partition plate 46 fixedly connected to the middle of the inner surface of the fixed sleeve 13, a fixed rod 24 fixedly connected to the outer surface of the partition plate 46, a guiding groove 25 is formed on the outer surface of the fixed rod 24, a support strip 28 is slidably connected to the outer surface of the guiding groove 25, a second heating plate 27 is slidably connected to the outer surface of the support strip 28, and a discharge pipe 14 and a feed pipe 15 are wound around the outer surface of the second heating plate 27.

[0042] The number of the first heating plates 19 is several groups and they are distributed in a circular array, the second heating plate 27 is arc-shaped, the number of the guiding grooves 25 is several groups and they are distributed in a circular array, a limiting plate 26 is fixedly connected to the inner surface of the fixed sleeve 13, the number of the limiting plates 26 is two groups and they are symmetrically distributed on the upper and lower sides of the partition plate 46, and one end of the support strip 28 away from the guiding groove 25 is fixedly connected to the outer surface of the limiting plate 26.

[0043] A display screen 45 is embedded and fixedly connected to the outer surface of the front end of the body 11, a knob 47 is fixedly connected to the outer surface of the front end of the body 11, and the first heating plate 19, the second heating plate 27, and the heat preservation plate 42 are respectively electrically connected to the host control system.

[0044] By adopting the above technical solution, during operation, one end of the feed pipe 15 and the discharge pipe 14 is fixedly connected to the body 11 respectively, and the other ends of the feed pipe 15 and the discharge pipe 14 extend into the patient's abdominal cavity. The body 11 controls the liquid medicine to be injected into the patient's abdominal cavity through the feed pipe 15 for flushing treatment, and then the liquid medicine in the abdominal cavity is recovered into the body 11 through the discharge pipe 14. The body 11 can heat the liquid medicine and control and adjust the perfusion speed of the liquid medicine. When the liquid medicine is transported inside the feed pipe 15, part of the heat will volatilize outward through the feed pipe 15, resulting in a decrease in the temperature of the liquid medicine, which will have an adverse impact on the treatment effect. Therefore, a heat preservation component is provided. The body 11 supports the fixed sleeve 13 through the mounting plate 12. The fixed sleeve 13 supports and fixes the fixed rod 24 through the partition plate 46. The guide groove 25 formed on the surface of the fixed rod 24 is used for sliding and guiding the support bar 28. The support bars 28 symmetrically distributed inside the guide groove 25 are used for supporting and lifting the second heating plate 27. The feed pipe 15 and the discharge pipe 14 are spirally wound around the outer surface of the second heating plate 27. While ensuring the smooth flow of the liquid medicine, the second heating plate 27 continuously generates heat to keep the feed pipe 15 and the discharge pipe 14 warm. The first heating plate 19 inside the fixed sleeve 13 can further improve the heat preservation effect inside the fixed sleeve 13. The partition plate 46 inside the fixed sleeve 13 is used for separating the feed pipe 15 and the discharge pipe 14 inside the fixed sleeve 13, so as to reduce the probability of the feed pipe 15 and the discharge pipe 14 being wound around each other inside the fixed sleeve 13. By winding and storing the feed pipe 15 inside the fixed sleeve 13, the feed pipe 15 can be continuously kept warm, so as to effectively reduce the loss of heat when the liquid medicine flows inside the feed pipe 15, so that the temperature of the liquid medicine entering the patient's abdominal cavity can be maintained within an appropriate range, and further ensure the effect of hyperthermic perfusion treatment.

[0045] As Figures 3 to 5 shown, a buffer component is arranged on the inner side of the fixed sleeve 13. The buffer component includes notch openings 16 formed on the outer surface of the fixed sleeve 13. The number of the notch openings 16 is two groups. The two ends of the feed pipe 15 and the discharge pipe 14 respectively penetrate through the notch openings 16 to the outside of the fixed sleeve 13. The rear ends of the feed pipe 15 and the discharge pipe 14 are fixedly connected to the body 11. The support bar 28 is made of an elastic material. The discharge pipe 14 and the feed pipe 15 are spirally distributed on the outside of the second heating plate 27.

[0046] An elastic strip 48 is fixedly connected to the side of the outer surface of the support bar 28 away from the fixed rod 24. One end of the elastic strip 48 away from the support bar 28 is located inside the guide groove 25 and is fixedly connected to the fixed rod 24 through the guide groove 25. The number of the support bars 28 and the elastic strips 48 is several groups and they are correspondingly distributed with the second heating plate 27.

[0047] By adopting the above technical solution, both ends of the feed pipe 15 and the discharge pipe 14 extend to the outside of the fixed sleeve 13 through the notch 16. When the feed pipe 15 and the discharge pipe 14 are accidentally pulled during use, the risk of the feed pipe 15 and the discharge pipe 14 falling off from the patient's abdominal cavity will increase. Therefore, a buffer assembly is provided. The fixed rod 24 supports and holds the first heating plate 19 through the support bar 28 and the elastic strip 48. When the feed pipe 15 or the discharge pipe 14 is pulled, the pulling force will be transmitted to the inside of the fixed sleeve 13 through the feed pipe 15 and the discharge pipe 14. At this time, the support bar 28 and the elastic strip 48 will produce a certain degree of bending deformation, so that the first heating plate 19 moves toward the fixed rod 24. At this time, the distance between the first heating plate 19 and the fixed rod 24 becomes smaller, resulting in the disappearance of the first heating plate 19 received by the feed pipe 15 and the discharge pipe 14. At this time, the helically distributed feed pipe 15 and the discharge pipe 14 will gather and contract toward the fixed rod 24 under the action of the pulling force, so as to release the feed pipe 15 and the discharge pipe 14 on the surface of the first heating plate 19, so as to buffer the pulling force received by the feed pipe 15 and the discharge pipe 14, so as to reduce the pulling amplitude of the feed pipe 15 and the discharge pipe 14 to a certain extent, and further reduce the probability of the feed pipe 15 and the discharge pipe 14 falling off, which helps to improve the stability and safety during the hyperthermic perfusion treatment. After the pulling force disappears, the support bar 28 and the elastic strip 48 move in the reverse direction and reset under the action of their own elastic force, so as to push the second heating plate 27 to move away from the fixed rod 24, so as to continue to wind the excess feed pipe 15 and the discharge pipe 14 around the outside of the second heating plate 27 to reduce heat loss.

[0048] As Figure 4 and Figure 9 shown, a flow disturbance assembly is provided between the second heating plate 27 and the fixed rod 24. The flow disturbance assembly includes a bladder 40 fixedly connected to the outer surface of the fixed rod 24. One end of the outer surface of the bladder 40 away from the fixed rod 24 is fixedly connected to the outer surface of the second heating plate 27. The number of the bladders 40 is several groups and is distributed in a circular array. The upper and lower ends of the inner surface of the bladder 40 are fixedly connected with heat insulation plates 42, and the outer surface of the heat insulation plates 42 is provided with mesh holes 43.

[0049] The number of the mesh holes 43 is several groups and is distributed in a linear array. The lower outer surface of the bladder 40 is fixedly connected with a one-way intake pipe 41. The outer surface of the bladder 40 near the first heating plate 19 is fixedly connected with a one-way exhaust pipe 44. The one-way exhaust pipe 44 penetrates to the outside of the second heating plate 27. The number of the one-way exhaust pipes 44 is several groups and is distributed in a linear array.

[0050] By adopting the above technical solution, when the second heating plate 27 moves towards the fixed rod 24, the second heating plate 27 will cooperate with the fixed rod 24 to squeeze the capsule body 40. At this time, the gas inside the capsule body 40 will be discharged into the fixed sleeve 13 through the one-way air outlet pipe 44. The gas ejected from several groups of linearly distributed one-way air outlet pipes 44 will disturb the gas inside the fixed sleeve 13, so as to accelerate the flow of the warm gas inside the fixed sleeve 13, enabling the warm gas to fully contact the feed pipe 15 and the discharge pipe 14, thereby further improving the heat preservation effect on the liquid medicine. The heat preservation plate 42 inside the capsule body 40 can heat and keep warm the gas inside the capsule body 40. The mesh holes 43 on the surface of the heat preservation plate 42 can not only ensure the normal circulation of the gas, but also increase the contact area between the gas and the heat preservation plate 42, thereby improving the heat preservation effect on the gas inside the capsule body 40. When the second heating plate 27 moves away from the fixed rod 24, the second heating plate 27 will cooperate with the fixed rod 24 to stretch the capsule body 40. At this time, the gas inside the fixed sleeve 13 will enter the capsule body 40 through the one-way air inlet pipe 41 to inflate and expand the capsule body 40.

[0051] As Figure 5 and Figure 8 shown, a guiding component is arranged inside the notch 16. The guiding component includes a sliding rod 29 fixedly connected to the inner surface of the notch 16. Sliding sleeves 35 are respectively slidably connected to the outer surfaces of the feed pipe 15 and the discharge pipe 14. A mounting seat 34 is fixedly connected to the outer surface of the sliding sleeve 35. The sliding rod 29 penetrates through the upper and lower ends of the mounting seat 34 and is in sliding contact with the mounting seat 34. A first clamping groove 30 is formed on the outer surface of the sliding rod 29. A second clamping groove 32 is recessed and formed inside the sliding sleeve 35. The first clamping groove 30 and the second clamping groove 32 are internally connected. An adjusting rod 33 is threadedly connected to the outside of the mounting seat 34. One end of the adjusting rod 33 close to the sliding rod 29 is rotatably connected to a contact plate 31. The contact plate 31 is located inside the second clamping groove 32 and is in sliding contact with the inner surface of the second clamping groove 32. The contact plate 31 is arc-shaped. The sliding sleeves 35 and the mounting seats 34 are in two groups and are symmetrically distributed up and down.

[0052] By adopting the above technical solution, the notch 16 is used to fixedly support the sliding rod 29. The sliding rod 29 cooperates with the first card slot 30 to slide and guide the mounting seat 34. The sliding sleeves 35 on the outer surfaces of the feed pipe 15 and the discharge pipe 14 can slide and guide the discharge pipe 14 and the feed pipe 15. The two groups of sliding sleeves 35 cooperate with the mounting seat 34 to limit the feed pipe 15 and the discharge pipe 14. When it is necessary to fix the positions of the feed pipe 15 and the discharge pipe 14, the operator rotates the adjusting rod 33. The adjusting rod 33 is threadedly connected to the mounting seat 34 and will move into the first card slot 30 during rotation. During the movement of the adjusting rod 33, the contact plate 31 will be driven to move synchronously. By the moving plate being in contact with the inner surface of the first card slot 30, the mounting seat 34 can be clamped and limited, so that the mounting seat 34 and the sliding sleeve 35 can be kept stationary. By setting the guiding component, a good guiding effect can be achieved on the feed pipe 15 and the discharge pipe 14, effectively reducing the probability of entanglement between the feed pipe 15 and the discharge pipe 14, improving the smoothness of the feeding and discharging processes of the feed pipe 15 and the discharge pipe 14, and further improving the stability of the hot perfusion device during operation.

[0053] As Figure 3 and Figure 6 shown, a flow stabilizing component is arranged inside the feed pipe 15. The flow stabilizing component includes a flow stabilizing plate 38 fixedly connected to the inner surface of the feed pipe 15. The flow stabilizing plate 38 is arc-shaped and made of an elastic material. A baffle 36 is fixedly connected to the inner surface of the feed pipe 15. One end of the outer surface of the baffle 36 close to the flow stabilizing plate 38 is fixedly connected with a traction strip 37. The end of the traction strip 37 far from the baffle 36 is fixedly connected to the upper outer surface of the flow stabilizing plate 38. The number of the flow stabilizing plates 38 is several groups and they are distributed in a circular array.

[0054] A first core shaft 20 and a second core shaft 22 are fixedly connected between the partition plate 46 and the limiting plate 26. The number of the first core shaft 20 and the second core shaft 22 is two groups each. The outer surfaces of the two groups of the first core shafts 20 are respectively rotatably connected with a first guiding roller 21 and a second guiding roller 23. The outer surfaces of the two groups of the second core shafts 22 are respectively rotatably connected with a first pressing roller 17 and a second pressing roller 18. The first guiding roller 21, the second guiding roller 23, the first pressing roller 17 and the second pressing roller 18 are respectively in rotational contact with both ends of the feed pipe 15 and the discharge pipe 14. The rear end of the feed pipe 15 is arc-shaped, and a liquid outlet hole 39 is formed in the rear side of the outer surface of the feed pipe 15.

[0055] By adopting the above technical solution, in order to improve the fluidity during thermoperfusion, a flow stabilization component is arranged inside the feed pipe 15. The feed pipe 15 fixedly supports the traction bar 37 through the baffle 36, and the traction bar 37 always keeps the flow stabilization plate 38 in a gathered state by pulling it. When the liquid medicine is injected into the feed pipe 15 through the machine body 11, when the liquid medicine flows to the flow stabilization component inside the feed pipe 15, the liquid medicine will impact the flow stabilization plate 38 inside the feed pipe 15. The flow stabilization plate 38 will produce elastic deformation under the impact force of the liquid medicine, so that several groups of flow stabilization plates 38 expand outward from the gathered state. At this time, the liquid medicine will flow through the gaps between the flow stabilization plates 38, so as to effectively reduce the impact on the patient's abdominal cavity during the moment of liquid medicine flow. With the continuous injection of the liquid medicine, the flow stabilization plate 38 will always maintain an expanded state, so as to ensure the stable flow of the liquid medicine. Then the liquid medicine is injected into the patient's abdominal cavity through the liquid outlet hole 39 for flushing treatment. By setting the flow stabilization component, the elastic deformation of the flow stabilization plate 38 can buffer and offset the impact force during the moment of liquid medicine flow, so as to improve the stability during the liquid medicine perfusion process to a certain extent, and further reduce the pain during the liquid medicine perfusion treatment. The partition plate 46 and the limiting plate 26 fixedly support the first mandrel 20 and the second mandrel 22. The two groups of first mandrels 20 and second mandrels 22 respectively rotationally support the first guide roller 21, the second guide roller 23, the first squeezing roller 17, and the second squeezing roller 18. The first guide roller 21, the second guide roller 23, the first squeezing roller 17, and the second squeezing roller 18 respectively rotationally guide the two ends of the discharge pipe 14 and the feed pipe 15, making the movement of the discharge pipe 14 and the feed pipe 15 more stable.

[0056] The working process of the technical solution of the present invention is as follows:

[0057] One end of the feed pipe 15 and the discharge pipe 14 is fixedly connected to the machine body 11, and the other ends of the feed pipe 15 and the discharge pipe 14 extend into the patient's abdominal cavity. The machine body 11 controls the injection of the liquid medicine into the patient's abdominal cavity through the feed pipe 15 for flushing treatment. The elastic deformation of the steady flow plate 38 can buffer and offset the impact force of the liquid medicine flow instantaneously. By setting the guiding assembly, it can play a good guiding role for the feed pipe 15 and the discharge pipe 14, and can effectively reduce the probability of mutual entanglement between the feed pipe 15 and the discharge pipe 14. The feed pipe 15 and the discharge pipe 14 are spirally wound around the outer surface of the second heating plate 27. While ensuring the smooth flow of the liquid medicine, the second heating plate 27 continuously generates heat to keep the feed pipe 15 and the discharge pipe 14 warm, which can effectively reduce the heat loss of the liquid medicine flowing inside the feed pipe 15, so as to keep the temperature of the liquid medicine entering the patient's abdominal cavity within an appropriate range. When the feed pipe 15 and the discharge pipe 14 are accidentally pulled during use, the spirally distributed feed pipe 15 and discharge pipe 14 will gather and contract towards the fixed rod 24 under the action of the pulling force, so as to release the feed pipe 15 and the discharge pipe 14 on the surface of the first heating plate 19, thereby buffering the pulling force on the feed pipe 15 and the discharge pipe 14, and thus reducing the pulling amplitude of the feed pipe 15 and the discharge pipe 14 to a certain extent. The second heating plate 27 will cooperate with the fixed rod 24 to squeeze the airbag 40, and the airbag 40 sprays out gas to disturb the warm gas inside the fixed sleeve 13, so that the warm gas can fully contact the feed pipe 15 and the discharge pipe 14, thereby further improving the heat preservation effect of the liquid medicine.
