Description

Technical Field

[0001] The utility model relates to the field of IABP medical equipment, in particular to a fixing device for an IABP extracorporeal catheter. Background Art

[0002] Intra-aortic balloon pump (IABP) is a widely used left ventricular assist therapy for critically ill patients. IABP refers to the implantation of a balloon-carrying catheter into the descending aorta at the distal end of the left subclavian artery opening and above the renal artery opening through the arterial system. The balloon is inflated during diastole to increase coronary perfusion, and deflated before cardiac contraction to reduce cardiac afterload, thereby achieving cardiac assist and causing phase changes in blood flow in the aorta, thereby achieving the therapeutic purpose of improving the pump function of the left ventricle and improving the perfusion of important organs. IABP is usually inserted into the body through the femoral artery sheath, and part of the external tube needs to be fixed on the surface of the limb on the puncture side. Since the tip of the IABP balloon needs to be accurately placed 1 cm distal to the opening of the patient's descending aorta and left subclavian artery to achieve the best treatment effect, the patient's daily turning over and limb activities may cause the balloon tip to shift, greatly affecting the effect of counterpulsation, and may cause serious complications such as tip penetration of blood vessels, intestinal necrosis, and acute kidney injury. Therefore, it is very important to effectively fix the external tube to prevent displacement.

[0003] At present, there is no dedicated device for fixing the IABP extracorporeal catheter in clinical practice. Elastic bandages, gauze, ordinary adhesive tape or wound dressing are usually used to fix the IABP extracorporeal catheter. These fixation methods have certain shortcomings:

[0004] 1. Use ordinary gauze, tape or disposable dressing to fix the catheter, which can only fix a certain point of the catheter and has poor fixation effect.

[0005] 2. Gauze or ordinary dressings are made of non-transparent materials. After being fixed, they will cover the outer surface of the catheter, which is not conducive to detecting the displacement or bending of the catheter.

[0006] 3. Adhesive auxiliary materials, elastic tapes, etc. can adhere to the film on the surface of the extracorporeal catheter and easily damage the film.

[0007] 4. Ordinary gauze, tape and other materials are disposable materials, which are not conducive to adjusting the position of the extracorporeal catheter at any time. If the position of the extracorporeal catheter needs to be adjusted, the fixing material needs to be completely removed. After adjusting the position of the extracorporeal catheter, the dressing needs to be replaced again to fix it again, which easily leads to a large amount of material waste. Utility Model Content

[0008] The utility model provides a fixing device for an IABP extracorporeal catheter, which solves the problem that during the IABP treatment process, the extracorporeal catheter reserved outside the patient's body cannot be effectively fixed, and the position of the extracorporeal catheter is difficult to adjust after fixation, which is not conducive to the patient's recovery.

[0009] In order to achieve the above-mentioned purpose, the utility model provides a fixing device for an IABP extracorporeal catheter, comprising a fixing body, a first adhesive layer for bonding and fixing the fixing body to the patient's body surface is provided at the bottom of the fixing body, a second adhesive layer and a flexibly changeable fixing groove are provided at the top of the fixing body, and an opening is provided at the top of the fixing groove; a fitting connected to the second adhesive layer is provided at the top of the fixing groove, a transparent observation layer is provided on the fitting, and the observation layer covers the opening.

[0010] In one embodiment, a scale is disposed on the top of the fixing body, and the scale is located beside the fixing groove, and a scale direction of the scale is parallel to an extending direction of the fixing groove.

[0011] In one embodiment, a protrusion for anti-slip is arranged on the inner wall of the fixing groove, and the protrusion is arranged along the length direction of the inner wall of the fixing groove.

[0012] In one embodiment, the fitting is provided with reinforcement layers located on both sides of the observation layer, and the reinforcement layers are connected to the second adhesive layer.

[0013] In one embodiment, a recording area for recording working data is provided on the top of the reinforcement layer.

[0014] In one embodiment, there are multiple second adhesive layers, and the multiple second adhesive layers are respectively disposed on both sides of the fixing groove.

[0015] In one embodiment, the first adhesive layer and the second adhesive layer each include a plurality of Velcro strips spaced apart along the length direction of the fixing body.

[0016] In one embodiment, the fixing groove comprises a groove body, and the width of the inner wall of the groove body is greater than the width of the inner wall of the opening.

[0017] In one embodiment, the trough body includes a base, and a first extension block and a second extension block are symmetrically arranged above the base and are close to each other. The opening is located between the first extension block and the second extension block, and when the first extension block and the second extension block are subjected to pressure from inside the trough body toward outside the trough body, the first extension block and the second extension block move away from each other.

[0018] Compared with the prior art, the fixing device for an IABP extracorporeal catheter in the embodiment of the utility model has the following beneficial effects:

[0019] When the utility model is actually used, the medical staff adheres and fixes the fixed body to the patient's body surface through the first adhesive layer at the bottom of the fixed body, and places the IABP catheter exposed outside the patient's body into the fixed groove through the opening at the top of the fixed groove, and the visual observation layer in the fitting is attached to the opening. The setting of the visual observation layer and the opening enables the medical staff to observe the situation of the extracorporeal catheter in time without affecting the IABP catheter exposed outside the patient's body, and understand the patient's physical condition through the situation of the extracorporeal catheter; the setting of the first extension block and the second extension block, when the extracorporeal catheter needs to be placed into the fixed groove, the medical staff applies a force toward the outside of the groove between the first extension block and the second extension block, and the first extension block and the second extension block move away from each other, so that the width of the opening increases, and the extracorporeal catheter enters the fixed groove through the opening. After the extracorporeal catheter enters the fixed groove, the first extension block and the second extension block lose the external force and move closer to each other under the action of elastic force, and the width of the opening is less than the width of the groove body; the bonding of the first adhesive layer and the second adhesive layer is Velcro bonding, so that the medical staff does not need to re-fix the extracorporeal catheter when adjusting the position of the extracorporeal catheter. The utility model effectively solves the problem that during the IABP treatment process, the extracorporeal catheter reserved outside the patient's body cannot be effectively fixed, and adjusting the position of the extracorporeal catheter after fixation is time-consuming and labor-intensive, which is not conducive to the patient's recovery.

[0032] In the description of the present invention, it should be understood that the terms "first" and "second" are used in the present invention for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0033] like Figure 1-5As shown, a fixing device for an IABP extracorporeal catheter in a preferred embodiment of the utility model comprises a fixing body 10, a first adhesive layer 11 for bonding and fixing the fixing body 10 to the patient's body surface is provided at the bottom of the fixing body 10, a second adhesive layer 12 and a flexibly changeable fixing groove 20 are provided at the top of the fixing body 10, an opening 22 is provided at the top of the fixing groove 20; a fitting piece 30 connected to the second adhesive layer 12 is provided at the top of the fixing groove 20, a transparent observation layer 32 is provided on the fitting piece 30, and the observation layer 32 covers the opening 22.

[0034] Based on the above technical features, when the present invention is actually used, the medical staff adheres the fixed body 10 to the patient's body surface through the first adhesive layer 11 at the bottom of the fixed body 10, and places the IABP catheter exposed outside the patient's body into the fixed groove 20 through the opening 22 at the top of the fixed groove 20, and the visual observation layer 32 in the fitting is attached to the opening 22. The setting of the visual observation layer 32 and the opening 22 enables the medical staff to observe the situation of the extracorporeal catheter 40 in time without affecting the IABP catheter exposed outside the patient's body, and understand the patient's physical condition through the situation of the extracorporeal catheter 40. It should be noted that the fixed body 10 in the present invention is made of breathable material to ensure that the patient will not feel uncomfortable when wearing the device for a long time.

[0035] As some embodiments of the present utility model, Figure 1 As shown, the fixing body 10 further includes a scale ruler 13, which is disposed on the top of the fixing body 10 and is located beside the fixing groove 20, and the scale direction of the scale ruler 13 is parallel to the extension direction of the fixing groove 20. The scale of the scale ruler 13 can display the liquid level of the catheter in the fixing groove 20 at any time, so that medical staff can make a preliminary judgment on the patient's recovery status through the change of the liquid in the extracorporeal catheter 40.

[0036] As some embodiments of the present utility model, Figure 2-3 As shown, a protrusion 23 for anti-slip is provided on the inner wall of the fixing groove 20, and the protrusion 23 is provided along the length direction of the inner wall of the fixing groove 20. The provision of the protrusion 23 can increase the friction between the fixing groove 20 and the extracorporeal catheter 40, and at the same time prevent the extracorporeal catheter 40 and the thin film on the surface from directly contacting the inner wall of the fixing groove 20, and can also play a good protective role for the extracorporeal catheter 40 and the thin film on the surface.

[0037] As some embodiments of the present utility model, Figure 2As shown, the fitting 30 further includes reinforcement layers 31 located on both sides of the observation layer 32, and the reinforcement layers 31 are connected to the second adhesive layer 12. The provision of the reinforcement layers 31 enables the fitting 30 to be bonded to the fixed body 10, and the reinforcement layers 31 increase the bonding area between the fitting 30 and the fixed body 10, thereby fixing the extracorporeal catheter 40 in the fixing groove 20.

[0038] As some embodiments of the present utility model, Figure 2 As shown, a recording area 311 for recording working data is provided on the top of the reinforcement layer 31. The setting of the recording area 311 enables the medical staff to record the relevant data of each patient's extracorporeal catheter 40 in the recording area 311 with a signature pen during the working process, and the next medical staff can understand the patient's condition through the data recorded in the recording area 311 on the patient's fixing device, thereby improving the working efficiency of the medical staff.

[0039] As some embodiments of the present utility model, Figure 2 As shown, there are multiple second adhesive layers 12, and the multiple second adhesive layers 12 are respectively arranged on both sides of the fixing groove 20, so as to further improve the stability of the extracorporeal catheter 40 in the fixing groove 20.

[0040] As some embodiments of the present utility model, Figure 2 As shown, the first adhesive layer 11 and the second adhesive layer 12 both include a plurality of Velcro strips arranged at intervals. The Velcro strips enable the first adhesive layer 11 and the second adhesive layer 12 to be adjusted in position according to actual use requirements, making it convenient for patients to wear the utility model.

[0041] As some embodiments of the present utility model, Figure 3 As shown, the fixing groove 20 includes a groove body 21, and the width of the inner wall of the groove body 21 is greater than the width of the inner wall of the opening 22. The extracorporeal catheter 40 is placed in the fixing groove 20 through the opening 22, which prevents the extracorporeal catheter 40 from falling off from the opening 22 during use of the utility model, thereby improving the stability of the fixing groove 20 in fixing the extracorporeal catheter 40.

[0042] As some embodiments of the present utility model, Figure 3As shown, the trough body 21 includes a base 211, and a first extension block 212 and a second extension block 213 close to each other are symmetrically arranged above the base 211, and the opening 22 is located between the first extension block 212 and the second extension block 213. When the first extension block 212 and the second extension block 213 are subjected to pressure from the inside of the trough body 21 toward the outside of the trough body 21, the first extension block 212 and the second extension block 213 move away from each other. The first extension block 212 and the second extension block 213 are both elastic structures. When the extracorporeal catheter 40 enters the fixed groove 20, the medical staff applies a force toward the outside of the groove body 21 between the first extension block 212 and the second extension block 213, so that the first extension block 212 and the second extension block 213 move away from each other, thereby increasing the width of the opening 22. At this time, the extracorporeal catheter 40 is able to enter the fixed groove 20 through the opening. After the extracorporeal catheter 40 enters the fixed groove 20, the first extension block 212 and the second extension block 213 lose the external force and approach each other under the action of the elastic force. At this time, the width of the opening 22 is smaller than the width of the groove body 21, and the opening 22 serves to limit the extracorporeal catheter 40.

[0043] The working process of the utility model is as follows: the fixing body 10 is bonded and fixed to the surface of the limb on the IABP puncture side of the patient and at the corresponding position below the extracorporeal catheter 40 through the first adhesive layer 11 at the bottom of the fixing body 10, and the adjusted extracorporeal catheter 40 enters the fixing groove 20 through the opening 22. The medical staff applies a force toward the outside of the groove body 21 between the first extension block 212 and the second extension block 213, so that the first extension block 212 and the second extension block 213 are separated from each other, thereby increasing the width of the opening 22. At this time, the extracorporeal catheter 40 enters the fixing groove 20 through the opening 22. After the extracorporeal catheter 40 enters the fixing groove 20, the first extension block 212 and the second extension block 213 lose external force and approach each other under the action of elastic force. At this time, the width of the opening 22 is smaller than the width of the groove body, and the opening 22 limits the extracorporeal catheter 40. Then, the fitting 30 and the second adhesive layer 12 are bonded to cover the top of the fixing groove 20. By bonding the observation layer 32 of the fitting 30 to the opening 22, the fitting further fixes the extracorporeal catheter 40 in the fixing groove 20. At the same time, medical staff can observe the liquid level of the extracorporeal catheter 40 that has been fixed through the observation layer 32.

[0044] In summary, the embodiment of the utility model provides a fixing device for an IABP extracorporeal catheter 40. When the utility model is actually used, the medical staff fixes the fixing body 10 to the patient's body surface through the first adhesive layer 11 at the bottom of the fixing body 10, and places the IABP catheter exposed outside the patient's body into the fixing groove 20 through the opening 22 at the top of the fixing groove 20, and the visual observation layer 32 in the fitting 30 fits with the opening 22. The setting of the visual observation layer 32 and the opening 22 enables the medical staff to observe the situation of the extracorporeal catheter 40 in time without affecting the IABP catheter exposed outside the patient's body, and understand the patient's physical condition through the situation of the extracorporeal catheter 40; the first extension block 212 and the second extension block 213 are connected to the fixing groove 20, and the medical staff can also use the first extension block 214 and the second extension block 215 to fix the IABP catheter exposed outside the patient's body. The extension block 213 is set, when the extracorporeal catheter 40 needs to be placed in the fixed groove 20, the medical staff applies a force toward the outside of the groove body 21 between the first extension block 212 and the second extension block 213, and the first extension block 212 and the second extension block 213 move away from each other, so that the width of the opening 22 increases, and the extracorporeal catheter 40 can enter the fixed groove 20 through the opening 22. After the extracorporeal catheter 40 enters the fixed groove 20, the first extension block 212 and the second extension block 213 lose the external force and move closer to each other under the action of elastic force, and the width of the opening 22 is smaller than the width of the groove body 21; the first adhesive layer 11 and the second adhesive layer 12 are both bonded by Velcro, so that the medical staff does not need to re-fix the extracorporeal catheter 40 when adjusting the position of the extracorporeal catheter 40. The utility model effectively solves the problem that the extracorporeal catheter 40 reserved outside the patient cannot be effectively fixed during the IABP treatment process, and it is time-consuming and labor-intensive to adjust the position of the extracorporeal catheter 40 after fixation, which is not conducive to the patient's recovery.

[0045] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
