Description

Technical Field

[0001] The utility model relates to the technical field of medical care products, in particular to a CRRT peripheral circulation passage fixer. Background Art

[0002] CRRT (continuous renal replacement therapy) is the abbreviation of continuous renal replacement therapy. It is also known as CBP (continue blood purification); bedside blood filtration. It is defined as a long-term, continuous extracorporeal blood purification therapy that uses 24 hours or nearly 24 hours a day to replace damaged kidney function.

[0003] Based on this, in major hospitals, when patients undergo bedside blood filtration, there are usually two blood inlet channels connected between the patient's blood vessels and the CRRT machine, one of which is used to transfer the blood in the patient's blood vessels to the CRRT machine for filtration, and the other is used to return the blood filtered by the CRRT machine to the patient's blood vessels. In actual operation, the patient usually lies flat on the bed, and the two corresponding blood inlet channels connected to the outside of his blood vessels are usually fixed to the skin of the patient's arm, etc. with medical tape or the like. Although this operation is widely used, the inventor of this patent found in his work that it still has certain defects and shortcomings.

[0004] Specifically, on the one hand, the medical tape used is in the shape of a long strip. When the blood catheter is adhered and pressed to the surface of the patient's skin, the inner surface near the location of the blood catheter is not well adhered to the patient's skin, so that after a certain period of use, the corresponding position is easy to debond, causing the blood catheter to be loose and not firmly fixed. On the other hand, when the blood catheter is adhered and pressed to the surface of the patient's skin, the fixed blood catheter directly presses the patient's skin for a long time, which is easy to cause pressure damage to the patient's skin, and the patient's skin will have complications such as skin lesions and sores.

[0005] In this regard, the inventor of this patent combined clinical experience, thought about the problems encountered in clinical work, read a large amount of scientific research materials and literature, and conducted searches and novelties to gradually conceive and design this application to solve related technical problems. Utility Model Content

[0006] The utility model aims to solve one of the technical problems in the related art at least to a certain extent. To this end, the purpose of the utility model is to provide a CRRT peripheral circulation pathway fixer.

[0007] To achieve one of the above purposes, a CRRT peripheral circulation passage fixture according to an embodiment of the utility model comprises a fixing post, a first pipe clamping member, a second pipe clamping member and a third pipe clamping member which are fixedly mounted on the upper end surface of the fixing post in parallel from left to right;

[0008] A first circular clamping groove for clamping the blood vessel channel is formed between the first clamping piece and the second clamping piece; a second circular clamping groove for clamping the blood vessel channel is formed between the second clamping piece and the three-clamping piece; the left and right widths of the upper notch of the first circular clamping groove and the left and right widths of the upper notch of the second circular clamping groove are both slightly smaller than their inner diameters.

[0009] In addition, the CRRT peripheral circulation pathway fixer according to the above embodiment of the utility model may also have the following additional technical features:

[0010] According to an embodiment of the utility model, the lower right side of the first clamping member is recessed to the left to form a first arc-shaped clamping surface, the lower left side of the second clamping member is recessed to the right to form a second arc-shaped clamping surface A, the lower right side of the second clamping member is recessed to the left to form a second arc-shaped clamping surface B, and the lower left side of the third clamping member is recessed to the right to form a third arc-shaped clamping surface;

[0011] The first circular clamping groove is formed between the first circular arc clamping surface and the second circular arc clamping surface A; the second circular clamping groove is formed between the second circular arc clamping surface B and the third circular arc clamping surface.

[0012] According to one embodiment of the utility model, the upper right portion of the first clamping member is chamfered to form a first sliding guide portion, the upper left portion of the second clamping member is chamfered to form a second sliding guide portion A, the upper right portion of the second clamping member is chamfered to form a second sliding guide portion B, and the upper left portion of the third clamping member is chamfered to form a third sliding guide portion;

[0013] The left and right sides of the upper notch of the first circular clamping groove are connected to the lower end of the first sliding guide part and the lower end of the second sliding guide part A; the left and right sides of the upper notch of the second circular clamping groove are connected to the lower end of the second sliding guide part B and the lower end of the third sliding guide part;

[0014] According to one embodiment of the utility model, the left-right distance between the first sliding guide portion and the second sliding guide portion A gradually decreases from top to bottom; the left-right distance between the second sliding guide portion B and the third sliding guide portion gradually decreases from top to bottom.

[0015] According to one embodiment of the utility model, a layer of clamping sponge sheet A is adhered to the first arc-shaped clamping surface; a layer of clamping sponge sheet B is adhered to the second arc-shaped clamping surface A; a layer of clamping sponge sheet C is adhered to the second arc-shaped clamping surface B; and a layer of clamping sponge sheet D is adhered to the third arc-shaped clamping surface.

[0016] According to an embodiment of the present invention, the fixing patch is shaped as a circle or an ellipse.

[0017] According to an embodiment of the utility model, it also includes a plastic patch that can be squeezed and deformed when under pressure, and the plastic patch is adhered to the bottom surface of the fixing patch;

[0018] According to an embodiment of the utility model, it also includes a tear film with a tear tab A at the periphery, and the tear film is adhered to the lower bottom surface of the plastic patch.

[0019] According to an embodiment of the present invention, the plastic patch is made of a copolymer of butene copolymer, gelatin, polypropylene glycol and ethylene-vinyl acetate.

[0020] According to an embodiment of the utility model, it also includes a fixing tape with a tear tab B at the end for fixing the blood guide tube, and the fixing tape is provided in plurality and adhered to the upper end surface of the fixing patch.

[0021] The beneficial effects of the utility model are:

[0022] First, in the specific implementation of the CRRT peripheral circulation pathway fixer provided by the present application, since the first tube clamping member, the second tube clamping member and the third tube clamping member are all fixedly mounted on the upper end surface of the fixing patch, the first circular clamping groove and the second circular clamping groove formed therebetween are both used to clamp the blood guide tube between the patient's blood vessel and the CRRT machine. Obviously, the bottom surface of the fixing patch provided in the present application will be adhered to the patient's skin surface in all directions without leaving any adhesion gap, so that compared with the medical tape adhesion method described in the background technology, the fixing patch of the present application is not easy to debond, so that the fixed blood guide tube is firmly fixed and not easy to loosen, so that the present application is stable and reliable to use.

[0023] Second, the ends of the two blood guide tubes connected between the patient's blood vessels and the CRRT machine that are close to the patient's body are fixed in the first circular clamping groove and the second circular clamping groove so as not to be fixed by compression, so as to avoid direct compression of the patient's skin and prevent pressure damage to the patient's skin. Therefore, the present application is safe to use.

[0024] Third, since the left and right widths of the upper notch of the first circular clamping groove and the left and right widths of the upper notch of the second circular clamping groove are slightly smaller than their inner diameters, when the ends of the two blood guide tubes connected between the patient's blood vessels and the CRRT machine close to the patient's body are pressed down with a little force, they can be simply clamped into the first circular clamping groove and the second circular clamping groove and fixed. Conversely, when the ends of the two corresponding blood guide tubes connected between the patient's blood vessels and the CRRT machine close to the patient's body are pulled upward with a little force, they can be correspondingly slid out of the first circular clamping groove and the second circular clamping groove and taken out. As a result, the ends of the two blood guide tubes connected between the patient's blood vessels and the CRRT machine close to the patient's body can be easily and effortlessly disassembled and assembled.

[0025] Fourthly, by setting the clamping sponge sheet A and the clamping sponge sheet B, one of the blood guide blood vessels connected between the patient's blood vessel and the CRRT machine and fixed in the first circular clamping groove can be used to clamp and fix the corresponding one of the blood guide blood vessels, so that it is not easy to shake. Similarly, by setting the clamping sponge sheet C and the clamping sponge sheet D, another blood guide blood vessel connected between the patient's blood vessel and the CRRT machine and fixed in the second circular clamping groove can be used to clamp and fix the corresponding other blood guide blood vessel, so that it is not easy to shake.

[0026] Fifth point, since the clamping sponge sheet A and the clamping sponge sheet B are both made of cotton material, they have a certain flexibility and stretchability, so that the clamping degree between them can be adjusted, so that the first circular clamping groove can be used to clamp one of the corresponding blood guide blood channels with different outer diameters within a suitable range. Similarly, since the clamping sponge sheet C and the clamping sponge sheet D are both made of cotton material, they have a certain flexibility and stretchability, so that the clamping degree between them can also be adjusted, so that the second circular clamping groove can be used to clamp another corresponding blood guide blood channel with different outer diameters within a suitable range.

[0027] Sixth, when the fixing patch is formed into a circular or oval shape, its periphery is smooth, so that it is not easy to hit and pierce the patient's skin, making the application safer and more reliable to use.

[0028] Seventh point, since the present application includes a plastic patch with a certain thickness that can be squeezed and deformed when under pressure and is adhered to the bottom surface of the fixing patch, the plastic patch is adhered to the desired position on the patient's skin. Even if the skin on the patient's skin at the desired position is uneven, such as on the arm, after the plastic patch is pressed with a little force, it will automatically shape to automatically fill the uneven parts of the patient's skin. In this way, it can be better adhered to the patient's skin together with the fixing patch, so that the fixing effect of the present application is excellent, and the fixation is stable and reliable.

[0029] Additional aspects and advantages of the present invention will be given in part in the following description, and in part will become apparent from the following description, or will be learned through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0062] The CRRT peripheral circulation pathway fixer 1000 according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0063] Reference Figure 1 to Figure 2 As shown, the CRRT peripheral circulation passage fixer 1000 provided according to the embodiment of the utility model comprises a fixing patch 10, and a first pipe clamping member 20, a second pipe clamping member 30 and a third pipe clamping member 40 which are fixed on the upper end surface of the fixing patch 10 in parallel from left to right;

[0064] Among them, a first circular clamping groove for clamping the blood guide blood channel is formed between the first clamping member 20 and the second clamping member 30; a second circular clamping groove for clamping the blood guide blood channel is formed between the second clamping member 30 and the three-clamping member; the left and right widths of the upper notch of the first circular clamping groove and the left and right widths of the upper notch of the second circular clamping groove are both slightly smaller than their inner diameters.

[0065] Based on the above, it is clear that the present application is mainly used as a CRRT peripheral circulation pathway fixer 1000 during specific implementation.

[0066] Specifically, when applying the present application, the fixing patch 10 described in the present application is attached to a suitable position on the patient's skin surface, and the ends of the two blood guide tubes connected between the patient's blood vessels and the CRRT machine close to the patient's body can be correspondingly fixed into the first circular clamping groove and the second circular clamping groove. In this way, the present application can be easily used.

[0067] The use of the above-mentioned application will obviously have the following technical effects:

[0068] First, since the first tube clamping member 20, the second tube clamping member 30 and the third tube clamping member 40 are all fixedly mounted on the upper end surface of the fixing patch 10, the first circular clamping groove and the second circular clamping groove formed therebetween are used to correspond to the two blood vessel channels that are fixedly connected between the patient's blood vessels and the CRRT machine. Obviously, the bottom surface of the fixing patch 10 provided in the present application will be adhered to the patient's skin surface in all directions without leaving any adhesion gap, so that compared with the medical tape adhesion method described in the background technology, the fixing patch 10 of the present application is not easy to debond, so that the two blood vessel channels fixed are firmly fixed and not easy to loosen, so that the present application is stable and reliable to use.

[0069] Second, the ends of the two blood guide tubes connected between the patient's blood vessels and the CRRT machine that are close to the patient's body are fixed in the first circular clamping groove and the second circular clamping groove so as not to be fixed by compression, so as to avoid direct compression of the patient's skin and prevent pressure damage to the patient's skin. Therefore, the present application is safe to use.

[0070] Third, since the left and right widths of the upper notch of the first circular clamping groove and the left and right widths of the upper notch of the second circular clamping groove are slightly smaller than their inner diameters, when the ends of the two blood guide tubes connected between the patient's blood vessels and the CRRT machine that are close to the patient's body are pressed down with a little force, they can be simply clamped into the first circular clamping groove and the second circular clamping groove and fixed. Conversely, when the ends of the two corresponding blood guide tubes connected between the patient's blood vessels and the CRRT machine that are close to the patient's body are pulled upward with a little force, they can be correspondingly slid out of the first circular clamping groove and the second circular clamping groove and taken out. As a result, the ends of the two blood guide tubes connected between the patient's blood vessels and the CRRT machine that are close to the patient's body can be easily and effortlessly disassembled and assembled.

[0071] Furthermore, through the above-mentioned optimized design, the overall structure of the present application is highly practical and has good practical effects.

[0072] Further, in a specific implementation, according to an embodiment of the present utility model, the lower right side of the first tube clamping member 20 is recessed to the left to form a first arc-shaped clamping surface 201, the lower left side of the second tube clamping member 30 is recessed to the right to form a second arc-shaped clamping surface 302A301, the lower right side of the second tube clamping member 30 is recessed to the left to form a second arc-shaped clamping surface 302B, and the lower left side of the third tube clamping member 40 is recessed to the right to form a third arc-shaped clamping surface 401;

[0073] The first circular clamping groove is formed between the first arc-shaped clamping surface 201 and the second arc-shaped clamping surface 302A301 ; the second circular clamping groove is formed between the second arc-shaped clamping surface 302B and the third arc-shaped clamping surface 401 .

[0074] Thus, one of the blood guide blood vessels between the patient's blood vessel and the CRRT machine can be clamped by the first arc-shaped clamping surface 201 and the second arc-shaped clamping surface 302A301, and the other blood guide blood vessel between the patient's blood vessel and the CRRT machine can be clamped by the second arc-shaped clamping surface 302B and the third arc-shaped clamping surface 401.

[0075] Furthermore, in a specific implementation, according to an embodiment of the present invention, the upper right portion of the first tube clamping member 20 is chamfered to form a first sliding guide portion 202, the upper left portion of the second tube clamping member 30 is chamfered to form a second sliding guide portion A303, the upper right portion of the second tube clamping member 30 is chamfered to form a second sliding guide portion B304, and the upper left portion of the third tube clamping member 40 is chamfered to form a third sliding guide portion 402;

[0076] Wherein, the left and right sides of the upper notch of the first circular clamping groove are connected to the lower end of the first sliding guide portion 202 and the lower end of the second sliding guide portion A303; the left and right sides of the upper notch of the second circular clamping groove are connected to the lower end of the second sliding guide portion B304 and the lower end of the third sliding guide portion 402;

[0077] Moreover, in the present technical solution, according to an embodiment of the present utility model, the left-right distance between the first sliding-in guide portion 202 and the second sliding-in guide portion A303 gradually decreases from top to bottom; the left-right distance between the second sliding-in guide portion B304 and the third sliding-in guide portion 402 gradually decreases from top to bottom.

[0078] Therefore, by setting the first sliding guide part 202 and the second sliding guide part A303 of the above-mentioned structure for sliding guidance, one of the blood vessel channels connected between the patient's blood vessel and the CRRT machine can be smoothly and quickly inserted into the first circular clamping groove to be fixed. Similarly, by setting the second sliding guide part B304 and the third sliding guide part 402 of the above-mentioned structure for sliding guidance, another blood vessel channel connected between the patient's blood vessel and the CRRT machine can be smoothly and quickly inserted into the second circular clamping groove to be fixed.

[0079] Therefore, through the above-mentioned optimized design, the overall use effect of the present application can be effectively improved.

[0080] In addition, in the specific implementation, according to an embodiment of the utility model, the first arc-shaped clamping surface 201 is adhered with a layer of clamping sponge sheet A50; the second arc-shaped clamping surface 302A301 is adhered with a layer of clamping sponge sheet B60; the second arc-shaped clamping surface 302B is adhered with a layer of clamping sponge sheet C70; the third arc-shaped clamping surface 401 is adhered with a layer of clamping sponge sheet D80.

[0081] Therefore, by setting the clamping sponge sheet A50 and the clamping sponge sheet B60, one of the blood guide blood vessels connected between the patient's blood vessel and the CRRT machine and fixed in the first circular clamping groove can be used to clamp and fix the corresponding one of the blood guide blood vessels, so that it is not easy to shake circumferentially. Similarly, by setting the clamping sponge sheet C70 and the clamping sponge sheet D80, another blood guide blood vessel connected between the patient's blood vessel and the CRRT machine and fixed in the second circular clamping groove can be used to clamp and fix the corresponding other blood guide blood vessel, so that it is not easy to shake circumferentially.

[0082] Furthermore, since the clamping sponge piece A50 and the clamping sponge piece B60 are both made of cotton material, they have a certain flexibility and stretchability, so that the clamping degree between them can be adjusted, so that the first circular clamping groove can be used to clamp one of the corresponding blood guide blood channels with different outer diameters within a suitable range. Similarly, since the clamping sponge piece C70 and the clamping sponge piece D80 are both made of cotton material, they have a certain flexibility and stretchability, so that the clamping degree between them can also be adjusted, so that the second circular clamping groove can be used to clamp another corresponding blood guide blood channel with different outer diameters within a suitable range.

[0083] Furthermore, through the above-mentioned optimized design, the overall structure of the present application can be used with better effect.

[0084] Preferably, in the present technical solution, according to an embodiment of the present utility model, the fixing patch 10 is formed into a circular or elliptical shape.

[0085] Therefore, when the fixing patch 10 is designed to be round or oval, its periphery is smooth, so that it is not easy to hit and pierce the patient's skin, making the application safer and more reliable to use.

[0086] Furthermore, in a specific implementation, according to an embodiment of the utility model, the present application also includes a plastic patch 90 with a certain thickness that can be squeezed and deformed when under pressure, and the plastic patch is adhered to the bottom surface of the fixing patch 10.

[0087] Thus, the plastic patch 90 is adhered to the desired position on the patient's skin. Even if the skin on the patient's skin is uneven, such as on the arm, after the plastic patch 90 is pressed with a little force, it will automatically shape to automatically fill the uneven part of the patient's skin. In this way, it can be better adhered to the patient's skin together with the fixing patch 10, so that the fixing effect of the present application is excellent, and the fixing is stable and reliable.

[0088] Again, in a specific implementation, according to an embodiment of the utility model, the present application also includes a tear film 100 with a tear tab A1001 at the periphery, and the tear film 100 is adhered to the lower bottom surface of the plastic patch 90 .

[0089] Therefore, before using the present application, the plastic patch 90 is isolated and protected by the tear film 100 so that it can maintain good adhesion. When using the present application, medical staff can pinch the tear tab A1001 to quickly tear off the tear film 100, making the present application convenient to use.

[0090] And specifically, in the present application, according to an embodiment of the present utility model, the plastic patch 90 is made of a copolymer of butene copolymer, gelatin, polypropylene glycol and ethylene-vinyl acetate.

[0091] Therefore, it can be clearly seen that, as a material in the prior art, since the plastic patch 90 is made of a copolymer of butene, gelatin, polypropylene glycol and ethylene-vinyl acetate, it must be soft in texture like plasticine, so that it can be molded into any desired shape and is also self-adhesive.

[0092] Furthermore, when the present application is actually used, the plastic patch 90 is adhered to the desired position on the patient's skin. Even if the skin on the patient's skin at the desired position is uneven, such as on the arm, after the plastic patch 90 is pressed with a little force, it will automatically shape so as to automatically fill in the uneven parts of the patient's skin. In this way, it can be better adhered to the patient's skin together with the fixing patch 10, so that the present application has an excellent fixing effect and the fixation is indeed stable and reliable.

[0093] It should be added that, in a specific implementation, according to an embodiment of the utility model, the present application also includes a fixing tape 110 having a tear tab B1101 at the end for fixing the blood guide tube, and the fixing tape 110 is provided in plurality and adhered to the upper end surface of the fixing patch 10.

[0094] Therefore, when the present application is actually used, the present application is fixed to the patient's skin surface. When the ends of the two blood guide blood vessels connected between the patient's blood vessels and the CRRT machine close to the patient's body are correspondingly clamped into the first circular clamping groove and the second circular clamping groove, the two clamped blood guide blood vessels can be reinforced and fixed to the upper end surface of the fixing patch 10 using the fixing tape 110. The fixing tape 110 used can be adhered to the outer walls of the two blood guide blood vessels and the upper end surface of the fixing patch 10, or it can be directly adhered to the outside of the first clamping member 20, the second clamping member 30 and the third clamping member 40 to close the upper notch of the first circular clamping groove and the upper notch of the second circular clamping groove, so that the clamped blood guide blood vessels are less likely to slip out of the upper notch of the first circular clamping groove and / or the upper notch of the second circular clamping groove.

[0095] It should be noted here that how to use the fixing tape 110 provided in the present application can be determined according to actual needs.

[0096] It is further necessary to add that, in a specific implementation, according to the CRRT peripheral circulation pathway fixer 1000 provided in an embodiment of the utility model, the front-to-back lengths of the first tube clamp 20, the second tube clamp 30 and the third tube clamp 40 are preferably not less than 1.0 cm, so that the front-to-back lengths of the first circular clamp groove and the front-to-back lengths of the second circular clamp groove are not less than 1.0 cm, so that the clamping length and clamping area of ​​the blood guide tube are neither too large nor too small.

[0097] Other embodiments and the like are not described here by way of example.

[0098] In summary, the CRRT peripheral circulation pathway fixer 1000 provided by the present application, in a specific implementation, since the first tube clamping member 20, the second tube clamping member 30 and the third tube clamping member 40 are all fixedly arranged on the upper end surface of the fixing patch 10, the first circular clamping groove and the second circular clamping groove formed therebetween are both used to clamp the blood guide blood channel between the patient's blood vessel and the CRRT machine. Obviously, the lower bottom surface of the fixing patch 10 provided in the present application will be adhered to the patient's skin surface in all directions without leaving any adhesion gap, so that compared with the medical tape adhesion method described in the background technology, the fixing patch 10 of the present application is not easy to debond, so that the fixed blood guide blood channel is firmly fixed and not easy to loosen, so that the present application is stable and reliable to use.

[0099] Furthermore, the ends of the two blood guide tubes connected between the patient's blood vessels and the CRRT machine that are close to the patient's body are fixed in the first circular clamping groove and the second circular clamping groove accordingly, so that they are not fixed in a press-fitting manner, and are not likely to directly compress the patient's skin, making it difficult for the patient's skin to form pressure injuries. Therefore, the present application is safe to use.

[0100] And because the left and right widths of the upper notch of the first circular clamping groove and the left and right widths of the upper notch of the second circular clamping groove are slightly smaller than their inner diameters, when the ends of the two blood guide tubes connected between the patient's blood vessels and the CRRT machine that are close to the patient's body are pressed down with a little force, they can be simply clamped into the first circular clamping groove and the second circular clamping groove and fixed. Conversely, when the ends of the two corresponding blood guide tubes connected between the patient's blood vessels and the CRRT machine that are close to the patient's body are pulled upward with a little force, they can be correspondingly slid out of the first circular clamping groove and the second circular clamping groove and taken out. As a result, the ends of the two blood guide tubes connected between the patient's blood vessels and the CRRT machine that are close to the patient's body can be easily and effortlessly disassembled and assembled.

[0101] In addition, by setting the clamping sponge sheet A50 and the clamping sponge sheet B60, it can be used to clamp one of the blood vessel channels connected between the patient's blood vessel and the CRRT machine and fixed in the first circular clamping groove, so that the corresponding one of the blood vessel channels is clamped firmly and is not easy to shake circumferentially. Similarly, by setting the clamping sponge sheet C70 and the clamping sponge sheet D80, it can be used to clamp the other blood vessel channel connected between the patient's blood vessel and the CRRT machine and fixed in the second circular clamping groove, so that the corresponding other blood vessel channel is clamped firmly and is not easy to shake circumferentially.

[0102] Furthermore, since the clamping sponge piece A50 and the clamping sponge piece B60 are both made of cotton material, they have a certain flexibility and stretchability, so that the clamping degree between them can be adjusted, so that the first circular clamping groove can be used to clamp one of the corresponding blood guide blood channels with different outer diameters within a suitable range. Similarly, since the clamping sponge piece C70 and the clamping sponge piece D80 are both made of cotton material, they have a certain flexibility and stretchability, so that the clamping degree between them can also be adjusted, so that the second circular clamping groove can be used to clamp another corresponding blood guide blood channel with different outer diameters within a suitable range.

[0103] Thirdly, when the fixing patch 10 is designed to be round or oval, its periphery is smooth, so that it is not easy to hit and pierce the patient's skin, making the application safer and more reliable to use.

[0104] Also, since the present application includes a plastic patch 90 with a certain thickness that can be squeezed and deformed when under pressure and is adhered to the lower bottom surface of the fixing patch 10, the plastic patch 90 is adhered to the desired position on the outside of the patient's skin. Even if the skin on the patient's skin at the desired position is uneven, such as on the arm, after the plastic patch 90 is pressed with a little force, it will automatically shape so as to automatically fill the uneven part of the patient's skin. In this way, it can be better adhered to the patient's skin together with the fixing patch 10, so that the fixing effect of the present application is excellent, and the fixation is stable and reliable.

[0105] Furthermore, the CRRT peripheral circulation pathway fixer 1000 provided by the present application is indeed extremely practical and has excellent use effects, which makes the present application bound to have a good market promotion value, and the present application is bound to be very popular and will be effectively popularized.
