Description

Technical Field

[0001] This invention relates to the field of vomit collection technology, specifically to a splash-proof, sealed radiotherapy / chemotherapy vomiting care device and its usage method. Background Technology

[0002] Chemotherapy and radiotherapy are important means of treating malignant tumors. However, while chemotherapy drugs and radiation can kill tumor cells, they can also cause significant toxic side effects on the patient's normal tissues. Nausea and vomiting are the most common and painful adverse reactions. In severe cases, they can even lead to dehydration, electrolyte imbalance, nutritional intake disorders and decreased treatment compliance. Frequent and severe vomiting not only seriously affects the patient's quality of life, but also poses a great challenge to clinical nursing work.

[0003] In clinical practice, wards are usually equipped with vomit collection containers to deal with sudden vomiting in patients. Currently, the most widely used collection devices include simple open plastic buckets, covered trash cans, or disposable vomit bags. However, these existing devices have many shortcomings in actual use: First, simple open buckets cannot effectively block the strong odor emitted by vomit, especially in multi-person wards or relatively enclosed spaces such as radiotherapy rooms and chemotherapy infusion rooms. The pervasive odor not only further induces the patient's nausea reflex, creating a vicious cycle, but also causes psychological and physiological discomfort to other patients and medical staff. Second, although disposable vomit bags can be sealed and disposed of, frequent replacement increases the amount of medical waste and the nursing burden. Finally, when using collection buckets to collect vomit, the high water content of the vomit makes it difficult for nursing staff to empty it, and usually requires rinsing the collection bucket with water.

[0004] To address the aforementioned issues, several improvements have been proposed, such as installing an activated carbon filter layer inside the lid or using a more airtight flip-top structure. However, these solutions only passively block odors and cannot proactively and effectively cover vomit that has already entered the container. The vomit itself is exposed to the air environment inside the container, and its volatile substances continue to be released. When the lid is opened or not properly sealed, the odor will escape quickly. Therefore, how to ensure that vomit is quickly covered after collection, thereby suppressing odor emission at the source, while simplifying nursing procedures and avoiding direct contact between patients and nursing staff and contaminants, has become a pressing technical problem to be solved in this field.

Detailed Implementation

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figures 1-9 This invention provides a technical solution: a splash-proof, sealed radiotherapy and chemotherapy vomiting care device, comprising an outer cylinder 1, a base 2 integrally fixedly connected to the bottom end of the outer cylinder 1, an inner cylinder 3 sleeved on the inner wall of the outer cylinder 1, a vomit collection assembly 4 installed on the top of the inner cylinder 3, a power assembly 5 for driving the inner cylinder 3 to rotate installed inside the base 2, a vomit burying body 6 for holding inside the base 2, a material lifting device 7 fixedly connected to the outer wall of the inner cylinder 3, and several material inlets 8 opened on the side wall of the inner cylinder 3. When the inner cylinder 3 drives the material lifting device 7 to rotate, the vomit burying body 6 is conveyed upward and enters the inner cylinder 3 through the material inlets 8 to bury the vomit. A cylinder cover 9 is hinged to the top of the outer cylinder 1.

[0025] In this embodiment, the receiving assembly 4 includes a receiving basin 41. The inner wall of the receiving basin 41 is a smooth arc shape that is concave towards the center. A collection hole 48 for collecting vomit is provided in the center of the receiving basin 41. A placement pad 42 for placing the mandible is fixedly connected to the inner wall of the receiving basin 41. A placement groove 43 conforming to the physiological curve of the mandible is provided on the surface of the placement pad 42. An insertion tube 44 is fixedly connected to the bottom end of the receiving basin 41. The diameter of the insertion tube 44 matches the inner diameter of the inner cylinder 3. Connecting blocks 45 are fixedly connected to the outer walls on both sides of the insertion tube 44. L-shaped connecting grooves 31 are provided on the inner walls on both sides of the top of the inner cylinder 3. The insertion tube 44 is inserted into the inner cylinder 3 and the connecting blocks 45 are installed in the connecting grooves 31.

[0026] Specifically, when the patient places their chin in the placement groove 43 on the surface of the placement pad 42 and vomits into the collection basin 41, the inner wall of the collection basin 41 is a smooth arc shape that is concave towards the center, which can effectively reduce the risk of vomit splashing outwards. The vomit enters the inner cylinder 3 through the collection hole 48. By inserting the cannula 44 into the inner cylinder 3 and inserting the connecting block 45 into the vertical section of the connecting groove 31, and then rotating the collection basin 41 so that the connecting block 45 enters the horizontal section of the connecting groove 31, the nursing staff can lift the collection basin 41 upwards and lift the inner cylinder 3 together, which makes it easier to remove the inner cylinder 3 and process the vomit inside.

[0027] In this embodiment, the top side of the receiving basin 41 is integrally provided with a skirt 46, and the bottom of the skirt 46 is provided with an annular limiting groove 47. The top of the outer cylinder 1 is integrally provided with a limiting ring 10, which is fastened in the annular limiting groove 47.

[0028] Specifically, the limiting ring 10, in conjunction with the annular limiting groove 47, can guide the axial rotation of the inner cylinder 3.

[0029] In this embodiment, the base 2 has an installation cavity 21. The power assembly 5 includes a drive motor 51 fixedly installed in the installation cavity 21. The output shaft of the drive motor 51 is fixedly connected to the power gear 52. The bottom of the base 2 has an installation hole that passes through the installation cavity 21 and a bearing is installed in the installation hole. The inner ring of the bearing is fixedly connected to the first connecting pipe 53. The bottom end of the first connecting pipe 53 extends into the installation cavity 21 and is fixedly connected to the driven gear 54. The driven gear 54 meshes with the power gear 52. The inner wall of the first connecting pipe 53 has a positioning groove 55. The bottom end of the inner cylinder 3 is integrally connected to the second connecting pipe 32. The outer wall of the second connecting pipe 32 is fixedly connected to the positioning strip 33. The second connecting pipe 32 is inserted into the first connecting pipe 53 and the positioning strip 33 is inserted into the positioning groove 55.

[0030] Specifically, when the inner cylinder 3 is installed inside the outer cylinder 1, the second connecting pipe 32 is inserted into the first connecting pipe 53 and the positioning strip 33 is inserted into the positioning groove 55. At this time, the limiting ring 10 is fastened in the annular limiting groove 47. When the drive motor 51 drives the power gear 52 to rotate, the driven gear 54 will drive the first connecting pipe 53 to rotate. Under the limiting effect of the positioning strip 33 and the positioning groove 55, the second connecting pipe 32 follows the first connecting pipe 53 to rotate. Therefore, in this way, the power component 5 can drive the inner cylinder 3 to rotate. When the inner cylinder 3 drives the lifting device 7 to rotate, it will transport the burial body 6 contained in the base 2 to the top and fall into the inner cylinder 3 through the feed port 8 to bury the vomit, thereby causing the vomit to clump together and masking and absorbing the odor.

[0031] In this embodiment, the material lifting device 7 includes an auger body 71. The top of the auger body 71 has a first opening 72 that matches the outer diameter of the outer cylinder 1. The outer cylinder 1 is inserted into the first opening 72 and fixedly connected to the auger body 71 by welding. The bottom of the auger body 71 has a second opening 73. The first connecting pipe 53 is inserted into the second opening 73. The auger body 71, the inner cylinder 3, and the outer cylinder 1 form a conveying passage 11. Several feed ports 8 are equidistantly distributed along the topmost conveying passage 11. The gap between the auger body 71 and the outer cylinder 1 does not exceed 3mm. The inner diameter of the second opening 73 matches the diameter of the first connecting pipe 53.

[0032] Specifically, since the inner cylinder 3 is welded and fixed to the auger body 71, when the inner cylinder 3 is placed into the outer cylinder 1, the second connecting pipe 32 is inserted into the first connecting pipe 53 and the first connecting pipe 53 is inserted into the second opening 73. Because the burial body 6 will obstruct the bottom of the auger body 71, when installing the inner cylinder 3, the second connecting pipe 32 is first inserted a small section into the first connecting pipe 53, and then the inner cylinder 3 is rotated. Therefore, the conveying passage 11 formed by the auger body 71, the inner wall of the outer cylinder 1, and the inner cylinder 3 will... The burial body 6 is conveyed upwards, so the inner cylinder 3 will continuously descend to the final installation position. Since the gap between the auger body 71 and the outer cylinder 1 is no more than 3mm, the risk of the burial body 6 falling out of the gap between the auger body 71 and the outer cylinder 1 can be reduced when the auger body 71 conveys the burial body 6. The feed inlets 8 are evenly distributed along the topmost conveying passage 11. Therefore, when the burial body 6 enters the topmost conveying passage 11, it will fall into the inner cylinder 3 through different feed inlets 8 to bury the vomit.

[0033] In this embodiment, the inner wall of the inner cylinder 3 is fixedly connected with a number of baffle plates 12 equal to the number of feed inlets 8. The baffle plates 12 are fixedly connected to the inner wall of the inner cylinder 3. The baffle plates 12 are inclined and each baffle plate 12 is located at the top of the corresponding feed inlet 8. The outer wall of the inner cylinder 3 is fixedly connected with an annular limiting plate 13 located at the top of the feed inlet 8.

[0034] Specifically, the baffle plate 12 protects the feed inlet 8 to prevent vomit from falling into the outer cylinder 1 through the feed inlet 8 when the patient's vomit enters the inner cylinder 3 through the collection hole 48. The annular limiting plate 13 limits the rising height of the burial body 6.

[0035] In this embodiment, the outer wall of the outer cylinder 1 is also fixedly connected to an end-connection assembly 14. The end-connection assembly 14 includes an outer ring 141 fixedly installed on the outer wall of the outer cylinder 1. A clearance groove 142 is provided at the bottom of one side of the outer ring 141. Both ends of the outer ring 141 are fixedly connected to connectors 143. The two connectors 143 are respectively rotatably connected to the two ends of a U-shaped end-connection handle 144. When the end-connection handle 144 is rotated to a horizontal state, the end-connection handle 144 abuts against the clearance groove 142.

[0036] Specifically, when nursing staff are unwilling to hold the outer cylinder 1 to collect the patient's vomit, they can unfold the end handle 144. At this time, under the limiting effect of the relief groove 142, the end handle 144 is in a horizontal state. The nursing staff can then hold the end handle 144 and send the outer cylinder 1 to the patient. This allows the nursing staff to extend the distance between themselves and the vomit, reducing the risk of physiological discomfort caused by close observation of the vomit.

[0037] In this embodiment, the burial body 6 is cat litter made of bentonite.

[0038] Specifically, bentonite cat litter has good odor absorption properties, so it can effectively absorb the odor produced by vomit. Moreover, when bentonite cat litter is used to bury vomit, the burying body 6 will quickly combine with the vomit to form a block due to the high water content of the vomit, thus reducing the difficulty of cleaning up the vomit. Furthermore, since the inlet 8 connects the inner cylinder 3 to the outer cylinder 1, the burying body 6 in the base 2 can also continuously absorb the odor produced by the vomit in the inner cylinder 3, thereby reducing the rapid escape of odor when the lid 9 is opened, which would lead to a poor air environment in the ward. In addition, the vomit that has formed a block is easier to dispose of.

[0039] In this embodiment, a buckle device 15 for fixing the cylinder cover 9 is installed between the outer cylinder 1 and the cylinder cover 9. A sealing strip 16 is fixedly connected to the bottom end of the cylinder cover 9. When the cylinder cover 9 is fully closed and the buckle device 15 is connected, the sealing strip 16 is in a compressed state and the skirt 46 does not contact the inner wall of the cylinder cover 9.

[0040] Specifically, after the patient finishes vomiting during radiotherapy and chemotherapy, the cap 9 can be quickly closed. At this time, the outer cylinder 1 and the cap 9 are connected by the snap-fit ​​device 15. The sealing strip 16 is in a compressed state, which allows the cap 9 to block the odor generated in the inner cylinder 3 and the outer cylinder 1. At this time, the inner cylinder 3 is driven to rotate by the power component 5, and the auger body 71 lifts the burial body 6 upward and allows the burial body 6 to enter the inner cylinder 3 through the feed port 8, thereby burying the vomit. Moreover, the burial body 6 can also absorb the odor in the sealed space. Therefore, when the device is used again during radiotherapy and chemotherapy, because the vomit is buried and clumped, no odor will escape from the inside when the cap 9 is opened, improving the patient's comfort when using the device.

[0041] In this embodiment, the bottom end of the base 2 is fixedly connected to the bottom cover 17 by screws. The bottom cover 17 is equipped with a battery 18. The mounting cavity 21 is equipped with a PCB board 19 and a control board 20. The PCB board 19 is provided with a charging interface. The PCB board 19 is electrically connected to the battery 18 to charge the battery 18. The drive motor 51 is electrically connected to the battery 18 through the control board 20. The control board 20 is provided with a control button 201.

[0042] Specifically, the bottom cover 17 is removed by unscrewing the screws, making it easy to inspect the power component 5 inside the mounting cavity 21. The PCB board 19 facilitates the charging of the battery 18, allowing the vomiting care device to be recharged and reused. The caregiver controls the start and stop of the drive motor 51 via the control button 201. Therefore, after the patient finishes vomiting, the caregiver can start the drive motor 51 via the control button 201. Under the action of the power gear 52 and the driven gear 54, the first connecting pipe 53 rotates, which in turn causes the inner cylinder 3 to rotate, thus rotating the lifting device 7 and lifting the contents of the base 2. The burial body 6 is lifted and conveyed upwards. The burial body 6 enters the inner cylinder 3 through the feed port 8 to bury the vomit. When it is necessary to dump the clumped vomit, the skirt 46 is lifted so that the receiving assembly 4 drives the inner cylinder 3 to rise from the outer cylinder 1. Then the receiving basin 41 is rotated and lifted upwards. At this time, the insertion tube 44 is disengaged from the inner cylinder 3, which facilitates the treatment of the clumped vomit. At this time, it is also convenient to replenish the burial body 6 into the base 2. This nursing device can quickly bury the vomit after it is collected, suppressing the emission of odor from the source. Moreover, the vomit buried by the burial body 6 will clump, which makes it easier to treat the vomit.

[0043] A method of using the above-mentioned vomiting care device, including a splash-proof, sealed radiotherapy / chemotherapy vomiting care device, further comprising the following steps: S1. Open the lid 9 and collect the vomit through the receiving component 4; S2. Close the cylinder cover 9, drive the inner cylinder 3 to rotate through the power component 5, and use the material lifting device 7 to transport the burial body 6 upward and drop it into the inner cylinder 3 to bury the vomit.
