A nursing hemostatic device and a hemostatic method for hemodialysis

Abstract

The present invention relates to the technical field of nursing hemostasis, and discloses a nursing hemostasis device and a hemostasis method for hemodialysis. In the present invention, the dressing output from the dressing output mechanism can pass through the dressing connection belt and be input into the interior of the dressing winding sleeve. The winding driving mechanism rotates inside the dressing winding sleeve to fully wind the affected area to be hemostatic with the dressing. Moreover, due to the driving of the winding driving mechanism, the stretching lengths of the two edges of the dressing are greater than the stretching length of the middle part of the dressing, so that the dressing can be fully adhered to the affected area and the adhesiveness can be ensured by the increase of the stretching length, effectively ensuring the isolation of the dressing from the affected area. Then, the inflation volume of at least one pressure airbag exceeds the inflation volumes of the other pressure airbags, so that several pressure airbags with large inflation volumes exactly correspond to the affected area parts that need to stop bleeding, thereby being able to provide a more sufficient pressure to improve the hemostasis efficiency of the affected area parts that need to stop bleeding.

Description

Technical Field

[0001] The present invention relates to the technical field of nursing hemostasis, and particularly to a nursing hemostasis device and a hemostasis method for hemodialysis. Background Art

[0002] Hemostasis is indispensable in both surgical procedures and daily trauma treatment, disease treatment, etc. In particular, during hemodialysis, a vascular access, such as an arteriovenous fistula, needs to be established to ensure sufficient blood flow. However, after each hemodialysis session, hemostasis at the puncture site becomes a key issue.

[0003] Some existing hemostasis devices use the method of overall compression to achieve the hemostasis function. Such devices usually apply uniform pressure to the entire wound area in an attempt to stop blood from flowing out. The overall compression method lacks pertinence. The blood vessel distribution and physiological structure vary greatly in different parts of the human body, and the conditions of wounds are also different. Some wounds may only be caused by local small blood vessel rupture and bleeding, while overall compression will cause unnecessary pressure on a large area of tissue, affecting local blood circulation, leading to ischemia and hypoxia of the surrounding tissues, and increasing the risk of tissue damage and necrosis.

[0004] Secondly, it is difficult to accurately control the pressure magnitude during overall compression. If the pressure is too small, it cannot effectively stop bleeding, while if the pressure is too large, it may further damage blood vessels and surrounding tissues, exacerbate the bleeding condition or cause new complications. The physical conditions and tolerance abilities of different patients are different, and the appropriate pressure required for the same wound also varies. However, overall compression hemostasis devices often cannot be flexibly adjusted according to individual differences, making it difficult to achieve the best hemostasis effect in practical applications. Summary of the Invention

[0005] In view of the deficiencies of the prior art, the present invention provides a nursing hemostasis device and a hemostasis method for hemodialysis.

[0006] To solve the above technical problems, the present invention provides the following technical solutions:

[0011] Preferably, the coating layer and the release paper are separated at one end of the coating layer input layer close to the coating layer winding sleeve, and the coating layer rotates inside the coating layer winding sleeve driven by the winding drive mechanism; the separated release paper enters the release paper recovery layer from one end of the release paper recovery layer close to the coating layer winding sleeve. After the separated release paper bypasses each recovery sliding roller shaft and passes through the guiding groove, it bypasses each recovery guiding roller and finally winds around the outside of the recovery winding roller.

[0012] Preferably, a coating layer speed-limiting gear is coaxially and fixedly arranged on one side of the coating layer mounting roller, and a recovery speed-limiting gear is coaxially and fixedly arranged on one side of the recovery winding roller. The coating layer speed-limiting gear and the recovery speed-limiting gear are of the same size, and the coating layer speed-limiting gear is in gear engagement with the recovery speed-limiting gear to limit the speed of the coating layer mounting roller for unwinding the coating layer to be equal to the speed of the recovery winding roller for winding the release paper.

The two sides of the elastic layer are respectively fixed inside the two winding skeletons, and a winding groove is formed on one side of the winding skeleton close to the elastic layer; the winding drive mechanism includes a winding drive motor and a winding conveying roller.

[0016] A hemostasis method for hemodialysis, using the above-mentioned nursing hemostasis device, includes the following steps:

[0017] Move the described nursing hemostatic device to the required position after hemodialysis by moving the body.

[0018] Take out the dressing winding sleeve and the pressure hemostasis sleeve from the inside of the storage bin, with the dressing winding sleeve on the inside and the pressure hemostasis sleeve on the outside, and set them on the affected area to be hemostatic.

[0019] Drive the dressing to wind around the bleeding point through the winding drive mechanism, and fully wind the affected area to be hemostatic with the dressing.

[0020] Under the control of the selected air supply mechanism, the air pressure pump can supply air to each pressure airbag through the air supply pipe respectively, and make the inflation volume of at least one pressure airbag exceed the inflation volumes of the other pressure airbags.

[0021] Compared with the prior art, the present invention provides a nursing hemostatic device and a hemostasis method for hemodialysis, having the following beneficial effects:

[0022] 1. For this nursing hemostatic device, the dressing output from the dressing output mechanism can pass through the dressing connecting belt and be input into the inside of the dressing winding sleeve. The winding drive mechanism rotates inside the dressing winding sleeve to fully wind the affected area to be hemostatic with the dressing. And due to the drive of the winding drive mechanism, the stretching lengths of the two edges of the dressing are greater than the stretching length of the middle part of the dressing, so that the dressing can be fully adhered to the affected area and the adhesiveness is ensured by the increase of the stretching length, effectively ensuring the isolation of the dressing from the affected area. Then, under the control of the selected air supply mechanism, the air pressure pump can supply air to each pressure airbag through the air supply pipe respectively, and make the inflation volume of at least one pressure airbag exceed the inflation volumes of the other pressure airbags, so that several pressure airbags with large inflation volumes exactly correspond to the affected area parts that need hemostasis, and thus can provide more sufficient pressure to apply pressure hemostasis to the affected area parts that need hemostasis, improving the hemostasis efficiency of the affected area parts that need hemostasis.

[0023] 2. For this nursing hemostatic device, the dressing carrying the release paper is guided and spread open by each output guiding roller and each input sliding roller shaft, so as to avoid contaminating the contact surface between the dressing and the wound surface before use. And the release paper separated from the dressing is guided by each recovery guiding roller and each recovery sliding roller shaft, so that the release paper can be stably conveyed and finally collected and recycled outside the recovery winding roller. And because the sizes of the dressing speed-limiting gear and the recovery speed-limiting gear are the same, and the dressing speed-limiting gear and the recovery speed-limiting gear are meshed with each other, the speed of the dressing installation roller unwinding the dressing is limited to be equal to the speed of the recovery winding roller winding the release paper, ensuring that the linear speeds of the movement between the release paper and the dressing are the same and ensuring the output stability between the release paper and the dressing.

[0024] 3. For this kind of nursing hemostatic device, the power output by the winding drive motor is transmitted through the gear meshing between the winding drive gear and the winding drive ring, driving the winding conveying roller to rotate around the winding skeleton. As a result, the dressing layer is adhered to the outside of the winding conveying roller by heating with the heating strip, and the dressing layer is driven by the winding conveying roller to wind within the range restricted by the winding skeleton. The diameters at both ends of the winding conveying roller are larger than the diameter in the middle. During the synchronous stretching process of the two side edges and the middle part of the dressing layer, the two side edges of the dressing layer have a greater moving length, so that the stretching length of the two side edges of the dressing layer is greater than that of the middle part of the dressing layer, fully adhering the dressing layer to the affected area and ensuring the adhesiveness by increasing the stretching length, effectively ensuring the isolation of the dressing layer from the affected area. After the winding is completed, the heating strip generates heat to cut off the dressing layer to complete the dressing layer wrapping of the affected area that needs hemostasis.

[0025] 4. For this kind of nursing hemostatic device, during the process that the air pressure pump supplies air to each pressure airbag through the air delivery pipe by the rotation between the batch connecting piece and the selection connecting piece, the main communication groove is sequentially communicated with each pressure airbag that needs high pressure, and the inflation volume of at least one pressure airbag exceeds that of other pressure airbags, so that several pressure airbags with a large inflation volume exactly correspond to the affected area that needs hemostasis. Furthermore, more sufficient pressure can be provided to apply pressure hemostasis to the affected area that needs hemostasis, improving the hemostasis efficiency of the affected area that needs hemostasis.

[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0041] As introduced in the background art, there are deficiencies in the prior art. To solve the above technical problems, the present application proposes a nursing hemostasis device and a hemostasis method for hemodialysis.

[0042] Embodiment 1: Please refer to Figures 1-13 , a nursing hemostasis device, including a mobile body 1. Inside the mobile body 1, an air pressure pump 2 and a dressing output mechanism 3 are provided. On one side of the front of the mobile body 1, a storage bin 11 is provided. Inside the storage bin 11, a dressing winding sleeve 4 and a pressure hemostasis sleeve 5 are stored. The dressing output by the dressing output mechanism 3 can pass through the dressing connecting belt 6 and be input into the inside of the dressing winding sleeve 4. The pressure hemostasis sleeve 5 is communicated with the air pressure pump 2 through an air delivery pipe 21. Inside the dressing winding sleeve 4, a winding driving mechanism 7 is provided. The winding driving mechanism 7 can drive the dressing to wind around the bleeding point. And under the drive of the winding driving mechanism 7, the stretching lengths of the two edges of the dressing are greater than the stretching length of the middle part of the dressing. On the side of the pressure hemostasis sleeve 5 close to the air delivery pipe 21, a selective air delivery mechanism 8 is provided. Inside the pressure hemostasis sleeve 5, a number of pressure air bags 51 are provided. Under the control of the selective air delivery mechanism 8, the air pressure pump 2 can supply air to each pressure air bag 51 through the air delivery pipe 21 respectively.

[0043] During use, first move the entire nursing hemostasis device to the vicinity of the patient in need of hemostasis by moving the body 1 (the specific range needs to be within the connection range of the dressing connecting belt 6 and the air delivery pipe 21). First, take out the dressing winding sleeve 4 and the pressure hemostasis sleeve 5 from the storage bin 11. Put the dressing winding sleeve 4 on the affected area of the patient that needs hemostasis, and then put the pressure hemostasis sleeve 5 outside the dressing winding sleeve 4. Under the control of the control terminal at the top of the moving body 1, the dressing output from the dressing output mechanism 3 can pass through the dressing connecting belt 6 and be input into the dressing winding sleeve 4. The winding driving mechanism 7 rotates inside the dressing winding sleeve 4 to fully wind the affected area to be hemostatic with the dressing. And because under the drive of the winding driving mechanism 7, the stretching length of the two edges of the dressing is greater than the stretching length of the middle part of the dressing (in actual use, through the setting of the winding conveying roller 72 in the following text, the diameters at both ends of the winding conveying roller 72 are greater than the diameter of the middle part, so that during the synchronous stretching process of the two edges and the middle part of the dressing, the two edges of the dressing have a greater moving length, thus making the stretching length of the two edges of the dressing greater than the stretching length of the middle part of the dressing), the dressing can be fully attached to the affected area and the adhesiveness is ensured by the increase in the stretching length, effectively ensuring the isolation of the dressing from the affected area. Then, under the control of the selected air delivery mechanism 8, the air pressure pump 2 can supply air to each pressure airbag 51 through the air delivery pipe 21, and make the inflation amount of at least one pressure airbag 51 exceed the inflation amounts of the other pressure airbags 51, so that the several pressure airbags 51 with a large inflation amount exactly correspond to the affected area that needs hemostasis, and thus can provide more sufficient pressure to apply pressure hemostasis to the affected area that needs hemostasis, improving the hemostasis efficiency of the affected area that needs hemostasis.

[0044] Embodiment 2: Please refer to Figures 1-13 , which is different from the above embodiment in that a replacement bin 12 is provided on the front of the moving body 1 and below the storage bin 11, and the dressing output mechanism 3 is arranged inside the replacement bin 12; a guiding groove 13 is provided between the replacement bin 12 and the storage bin 11, and one end of the dressing connecting belt 6 is communicated with the guiding groove 13.

[0045] The dressing output mechanism 3 includes a dressing mounting roller 31, several output guiding rollers 32, several recovery guiding rollers 33 and a recovery winding roller 34; two mounting brackets 14 are arranged inside the replacement bin 12, and the dressing mounting roller 31 and the recovery winding roller 34 are respectively installed inside the two mounting brackets 14; several output guiding rollers 32 are arranged on the side of the guiding groove 13 close to the dressing mounting roller 31, and several recovery guiding rollers 33 are arranged on the side of the guiding groove 13 close to the recovery winding roller 34.

[0046] During specific use, the coating installation roller 31 and the recycling winding roller 34 are respectively rotatably connected inside the two installation brackets 14. After the coating on the coating installation roller 31 is completely used up, a new coating roll can be reloaded on the coating installation roller 31 and the new coating can be connected to the old coating. Similarly, by removing the recycling winding roller 34 and cutting off the release paper and then re-pasting the release paper on the recycling winding roller 34, the use of a new coating can be restarted;

[0047] Inside the coating connection belt 6, there are a coating input layer 61 and a release paper recycling layer 62. On the side of the coating input layer 61 close to the release paper recycling layer 62, there are several input sliding roller shafts 63. On the side of the release paper recycling layer 62 close to the coating input layer 61, there are several recycling sliding roller shafts 64; The coating carried with the release paper output from the coating installation roller 31 first bypasses each output guiding roller 32, passes through the guiding groove 13 and enters the coating input layer 61. The coating carried with the release paper is conveyed inside the coating input layer 61 by bypassing each input sliding roller shaft 63 on the side of the release paper.

[0048] The coating and the release paper are separated at one end of the coating input layer 61 close to the coating winding sleeve 4. The coating rotates inside the coating winding sleeve 4 driven by the winding driving mechanism 7; The separated release paper enters the release paper recycling layer 62 from one end of the release paper recycling layer 62 close to the coating winding sleeve 4. After the separated release paper bypasses each recycling sliding roller shaft 64, passes through the guiding groove 13, and then bypasses each recycling guiding roller 33, it is finally wound around the outside of the recycling winding roller 34.

[0049] On one side of the coating installation roller 31, a coating speed-limiting gear 35 is coaxially fixed. On one side of the recycling winding roller 34, a recycling speed-limiting gear 36 is coaxially fixed. The coating speed-limiting gear 35 and the recycling speed-limiting gear 36 are of the same size and are in gear meshing with each other to limit the speed of the coating installation roller 31 for unwinding the coating and the speed of the recycling winding roller 34 for winding the release paper to be equal.

[0050] In use, the laminate-carrying release paper output from the laminate installation roller 31 first bypasses each output guide roller 32, passes through the guide groove 13 and enters the laminate input layer 61. The laminate-carrying release paper is conveyed in the laminate input layer 61 by bypassing each input sliding roller shaft 63 on the side of the release paper. The laminate and the release paper are separated at one end of the laminate input layer 61 close to the laminate winding sleeve 4. The laminate rotates inside the laminate winding sleeve 4 under the drive of the winding drive mechanism 7 for use. The separated release paper enters the release paper recovery layer 62 from one end of the release paper recovery layer 62 close to the laminate winding sleeve 4. After the separated release paper bypasses each recovery sliding roller shaft 64 and passes through the guide groove 13, it bypasses each recovery guide roller 33 and finally winds around the outside of the recovery winding roller 34. The laminate carrying the release paper can be guided and spread open by each output guide roller 32 and each input sliding roller shaft 63, so as to ensure that the contact surface between the laminate and the wound surface is not contaminated before use. The release paper separated from the laminate is guided by each recovery guide roller 33 and each recovery sliding roller shaft 64, so that the release paper can be stably conveyed and finally collected and recovered outside the recovery winding roller 34. Since the sizes of the laminate speed-limiting gear 35 and the recovery speed-limiting gear 36 are the same and the laminate speed-limiting gear 35 and the recovery speed-limiting gear 36 are meshed with each other, the speed of the laminate installation roller 31 unwinding the laminate is equal to the speed of the recovery winding roller 34 winding the release paper, ensuring that the linear speeds of the movement between the release paper and the laminate are the same and ensuring the output stability between the release paper and the laminate.

[0051] Embodiment 3: Please refer to Figures 1-13 , which is different from the above embodiment in that the laminate winding sleeve 4 includes two winding skeletons 41 and an elastic layer 42. Both sides of the elastic layer 42 are respectively fixed inside the two winding skeletons 41. A winding groove 43 is formed on one side of the winding skeleton 41 close to the elastic layer 42. The winding drive mechanism 7 includes a winding drive motor 71 and a winding conveyor roller 72. Winding drive rings 73 are fixed at both ends of the winding conveyor roller 72. The winding drive rings 73 are embedded inside the winding groove 43, and the winding drive rings 73 can rotate inside the winding groove 43.

[0052] A drive open groove 411 is formed on one side of the winding skeleton 41 close to the laminate connection belt 6. The output shaft of the winding drive motor 71 is coaxially fixed with a winding drive gear 74. The winding drive gear 74 is meshed with the winding drive ring 73. A heating strip is arranged on one side of the winding conveyor roller 72 close to the outside of the winding skeleton 41. The laminate can be cut off by the heat generated by the heating strip. The power output by the winding drive motor 71 can drive the winding drive ring 73 to drive the winding conveyor roller 72 to rotate around the winding skeleton 41, and wind the laminate within the range restricted by the winding skeleton 41.

[0053] Therefore, during use, due to the arrangement of the elastic layer 42, when the pressure airbag 51 is fully inflated, it can compress the elastic layer 42 to deform, thereby ensuring that the pressure generated by the pressure airbag 51 can effectively act on the affected area that needs to stop bleeding; the power output by the winding drive motor 71 is transmitted through the gear meshing of the winding drive gear 74 and the winding drive ring 73, driving the winding conveyor roller 72 to rotate around the winding skeleton 41, so that the dressing layer is adhered to the outside of the winding conveyor roller 72 by heating with the heating strip, and the dressing layer is driven by the winding conveyor roller 72 to wind within the range restricted by the winding skeleton 41 (the low-temperature heating dressing layer can adhere the dressing layer to the outside of the winding conveyor roller 72, and the high-temperature heating dressing layer can cut off the dressing layer outside the winding conveyor roller 72 and make the unused dressing layer adhere to the outside of the winding conveyor roller 72). The diameters of both ends of the winding conveyor roller 72 are larger than the diameter of the middle part, so that during the synchronous stretching process of the two side edges and the middle part of the dressing layer, the two side edges of the dressing layer have a greater moving length, so that the stretching length of the two side edges of the dressing layer is greater than the stretching length of the middle part of the dressing layer, fully attaching the dressing layer to the affected area and ensuring the adhesiveness by increasing the stretching length, effectively ensuring the isolation of the dressing layer from the affected area, and after the winding is completed, the heating strip can generate heat to cut off the dressing layer (a heating strip is arranged on the side of the winding conveyor roller 72 close to the outside of the winding skeleton 41 to prevent the heat generated by the heating strip from scalding the patient), so as to complete the dressing layer wrapping of the affected area that needs to stop bleeding.

[0054] The selection air delivery mechanism 8 includes a batch connection member 81 and a selection connection member 82. The batch connection member 81 and the selection connection member 82 are rotatably connected. One end of the selection connection member 82 away from the batch connection member 81 is communicated with the air delivery pipe 21; the batch connection member 81 has a plurality of connection channels 811, and the connection channels 811 are respectively communicated with each pressure airbag 51. A main communication groove 821 and a plurality of sub-communication grooves 822 are arranged inside the selection connection member 82; when the selection connection member 82 is rotated to any communication position, the main communication groove 821 is communicated with one pressure airbag 51, and each sub-communication groove 822 is respectively communicated with other pressure airbags 51. In specific implementation, the inner diameter of the main communication groove 821 is larger than the inner diameter of each sub-communication groove 822. At the same time, the air delivery pipe 21 is directly communicated with the main communication groove 821, and the air delivery pipe 21 is indirectly communicated with each sub-communication groove 822.

[0055] Thus, during use, when the air pressure pump 2 supplies air to each pressure airbag 51 through the air delivery pipe 21 by rotating between the batch connecting members 81 and the selective connecting member 82, the main communication groove 821 can be sequentially communicated with each pressure airbag 51 that requires high pressure, and the inflation amount of at least one pressure airbag 51 exceeds that of the other pressure airbags 51, so that several pressure airbags 51 with a large inflation amount exactly correspond to the affected area to be hemostatic. Furthermore, more sufficient pressure can be provided to apply pressure hemostasis to the affected area to be hemostatic, improving the hemostasis efficiency of the affected area to be hemostatic.

[0056] Embodiment 4: A hemostasis method for hemodialysis, which uses a nursing hemostasis device described in any one of Embodiments 1-3, includes the following steps:

[0057] Move a nursing hemostasis device to the required position after hemodialysis by moving the body 1;

[0058] Take out the dressing winding sleeve 4 and the pressure hemostasis sleeve 5 from the storage bin 11, and with the dressing winding sleeve 4 inside and the pressure hemostasis sleeve 5 outside, sleeved on the affected area to be hemostatic;

[0059] Drive the dressing to wind around the bleeding point through the winding drive mechanism 7 to complete the full winding of the affected area to be hemostatic with the dressing;

[0060] Under the control of the selected air delivery mechanism 8, the air pressure pump 2 can supply air to each pressure airbag 51 through the air delivery pipe 21, and the inflation amount of at least one pressure airbag 51 exceeds that of the other pressure airbags 51.

[0061] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
