Description

Technical Field

[0001] This utility model relates to the field of clinical medical device technology, specifically to an operating room catheter fixation device for preventing pressure injuries. Background Technology

[0002] Medical device-related pressure injury (MDRPI) refers to damage to the skin or subcutaneous tissue caused by the use of medical devices (such as catheters, masks, splints, etc.). Due to the poor mobility, low elasticity, hard material, and poor breathability of medical devices, improper use can directly exert pressure on the skin and subcutaneous tissue, leading to poor local blood circulation, which in turn causes local tissue ischemia and hypoxia, ultimately resulting in damage to the skin and soft tissue.

[0003] The inventor of this application is an anesthesiologist. Before performing surgery on a patient, it is necessary to fix the patient's upper limb to facilitate the operation. The necessary invasive hemodynamic monitoring channels are established in the patient's upper limb to monitor arterial pressure, deliver anesthetic drugs via intravenous catheter, and monitor blood oxygen saturation. These catheters are in direct contact with the patient's skin. Under the influence of prolonged pressure and humid environment, the patient's skin and soft tissue may be damaged. Utility Model Content

[0004] This invention addresses the problem of pressure injuries to patients in the operating room related to medical devices by providing a catheter fixation device for preventing pressure injuries in the operating room. The specific technical solution is as follows:

[0005] This utility model includes: a fixation member for securing an operating room catheter; a restraint strap for securing the fixation member to a patient's arm; and a buffer member disposed on the side of the restraint strap and the fixation member near the patient's arm, the buffer member being able to isolate the side of the restraint strap and the fixation member near the patient's arm from the patient's arm with a buffer structure.

[0006] Furthermore, the cushioning element is made of a soft, absorbent material, such as a sponge.

[0007] Preferably, the restraint strap includes a left restraint strap and a right restraint strap that are respectively connected to opposite sides of the fixing member. The side of the left restraint strap near the patient's arm is connected to the buffer member, and the side of the right restraint strap near the patient's arm forms a detachable connection structure with the other side of the restraint strap.

[0008] Preferably, the fixing member is made of a material with a resilient property. A through fixing groove is formed on the side of the fixing member away from the patient's arm. The fixing groove includes: a catheter groove for fixing the operating room catheter, the length direction of the catheter groove being the same as that of the operating room catheter, and the cross-section of the catheter groove being a "convex" shape; and a joint groove for fixing the catheter joint, with both opposite ends of the joint groove communicating with the catheter groove.

[0009] Preferably, the length directions of the fixing member, the restraint strap, and the buffer member are the same and their lengths are also the same.

[0010] Preferably, it further includes an integral restraint sleeve. The side of the restraint sleeve close to the patient's arm does not entirely cover the buffer member, and the remaining area of this side of the restraint sleeve that does not cover the buffer member forms a detachable connection structure with the opposite side of this side.

[0011] Preferably, the fixing member is connected to the side of the restraint strap away from the patient's arm, and a structure for adhesively fixing and separating the operating room catheter is formed on the side of the fixing member away from the patient's arm.

[0012] Preferably, the fixing member is a magic tape fixedly connected to the restraint strap. The magic tape can clamp the operating room catheter and fix it to the restraint strap, or the fixing member forms an adhesive surface with a certain adhesive force.

[0013] Preferably, it further includes a label associated with the operating room catheter, which shows the type of the associated operating room catheter, such as an invasive hemodynamic monitoring pipeline, an intravenous catheter for delivering anesthetic agents, and a blood oxygen saturation monitoring pipeline.

[0014] From the above technical solutions, the utility model has the following beneficial effects:

[0015] By arranging the left restraint strap to wind around the patient's arm and the right restraint strap to fix the left restraint strap, the fixing member fixed in the fixing groove can be relatively fixed with the patient's arm. Secondly, a buffer member is pasted on the inner surface of the left restraint strap so that it can form a contact with a larger contact area with the patient's arm, thereby reducing the pressure on the patient's arm and avoiding medical device-related pressure injuries to the patient's arm.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] Example 1

[0023] like Figure 1 As shown, the present invention includes: a fixing member 1 for fixing an operating room catheter; a restraint strap 3 for restraining the fixing member 1 to the patient's arm 7; and a buffer member 4 disposed on the side of the restraint strap 3 and the fixing member 1 near the patient's arm 7, the buffer member 4 being able to isolate the side of the restraint strap 3 and the fixing member 1 near the patient's arm 7 from the patient's arm 7 with a buffer structure.

[0024] Specifically, during the anesthesia procedure, the operating room catheter and the catheter connector that controls the flow rate within the operating room catheter are fixed to the top surface of the fixation component 1. The restraint strap 3 is fixedly connected to the opposite sides of the fixation component 1, so that after the restraint strap 3 is fixedly connected to the patient's arm 7, the fixation component 1 can be fixedly connected to the patient's arm 7, thereby fixing the operating room catheter, the catheter connector, and the patient's arm 7. This achieves the fixation of the invasive hemodynamic monitoring pipeline, the venous catheter, and the blood oxygen saturation monitoring pipeline. The venous catheter delivers various anesthetic agents and other agents to maintain the patient's vital signs. The catheter connector can be connected to multiple venous catheters simultaneously and is only connected to the patient's arm 7 through one infusion line. The flow rate is controlled by a flow control valve.

[0025] Secondly, the inner surface of the restraint strap 3 and the bottom surface of the fixation member 1 together form a cavity 1 for fixing to the patient's arm 7. The buffer member 4 is bonded to a portion of the inner surface of the restraint strap 3 and the bottom surface of the fixation member 1, so that the surface of the cavity 1 forms a buffer structure, so that the restraint strap 3 and the fixation member 1 are not in direct contact with the patient's arm 7. The buffer member 4 can absorb the pressure of the restraint strap 3 and the fixation member 1 on the patient's arm 7, and then contact the patient's arm 7 with a soft surface. Moreover, the buffering capacity of the buffer member 4 can avoid the restraint strap 3 and the fixation member 1 from applying pressure of hard contact to the patient's arm 7 for a long time, thereby avoiding medical device-related pressure injuries.

[0026] like Figure 2 As shown, the restraint strap 3 includes a left restraint strap 31 and a right restraint strap 32 that are respectively connected to the opposite sides of the fixing member 1. The side of the left restraint strap 31 near the patient's arm 7 is connected to the buffer member 4, and the side of the right restraint strap 32 near the patient's arm 7 is detachably connected to the other side of the restraint strap 3.

[0027] Specifically, the left restraint strap 31 is fixedly connected to the left side of the fastener 1, and the right restraint strap 32 is fixedly connected to the right side of the fastener 1. The inner surface of the left restraint strap 31 is connected to the surface of the buffer 4 with an adhesive, so that the buffer 4 is always in contact with the patient's arm 7 during the process of the left restraint strap 31 wrapping around the patient's arm 7, and the left restraint strap 31 does not contact the patient's arm 7, so as not to cause pressure injury to the patient's arm 7. Secondly, after the left restraint strap 31 wraps around the patient's arm 7, the inner surface of the right restraint strap 32 and the outer surface of the left restraint strap 31 are provided with Velcro structures, so that the right restraint strap 32 can fix the position of the left restraint strap 31 with Velcro, thereby fixing the fastener 1 to the patient's arm 7 by fixing the position of the left restraint strap 31 after the right restraint strap 32 wraps around the patient's arm 7, and the buffer 4 can always isolate the inner surface of the restraint strap 3 from the patient's arm 7.

[0028] Furthermore, the cushioning element 4 is made of a soft, absorbent material, such as a sponge.

[0029] Specifically, the soft material has a cushioning structure, which can convert the pressure of the inner surface of the restraint strap 3 and the fastener 1 into pressure on the patient's arm 7, thereby increasing the contact area with the patient's arm 7 and reducing the pressure on the patient's arm 7, thus reducing the possibility of pressure injury. Secondly, after the cushioning component 4 comes into close contact with the patient's arm 7, the sweat secreted by the patient's arm 7 will create a moist environment in the contact area, which will erode the skin of the patient's arm 7 and cause damage. The absorbent material can absorb the secreted sweat, so that the contact area between the cushioning component 4 and the patient's arm 7 is always a dry environment, thereby reducing the damage to the patient's skin.

[0030] Furthermore, the fixing member 1 is made of a material with resilience properties. On the side of the fixing member 1 away from the patient's arm 7, a through fixing groove 2 is formed. The fixing groove 2 includes: a catheter groove 21 for fixing the operating room catheter, the length direction of the catheter groove 21 is the same as the length direction of the operating room catheter, and the cross-section of the catheter groove 21 is "convex"; and a joint groove 22 for fixing the catheter joint, both opposite ends of the joint groove 22 are connected to the catheter groove 21.

[0031] Specifically, the fixing member 1 is made of a material with a certain degree of flexibility and elasticity. Its top surface forms a fixing groove 2 for placing the operating room catheter and the catheter joint. The operating room catheter passes through the fixing groove 2 to determine its position. Secondly, the size of the open end of the cross-section of the catheter groove 21 is smaller than the diameter of the operating room catheter, and the internal size of its cross-section is larger than the open end size and 0.5 - 1 mm smaller than the diameter of the operating room catheter. After the operating room catheter enters the catheter groove 2 by pressing, its open end can limit its movement, and the inner side of the catheter groove 21 can exert pressure on the operating room catheter but does not overly affect its flow, thereby fixing the operating room catheter to the fixing member 1.

[0032] Secondly, the catheter joint forms at least three joints, two of which are opposite along the length direction of the catheter groove 21. The catheter joint with operating room catheters connected at both ends is fixed in the joint groove 22 by being fixed in the catheter groove 21 through the operating room catheter, thereby facilitating the medical staff to operate the catheter joint to control the flow of the operating room catheter and improving the efficiency of the operation.

[0033] Furthermore, the length directions of the fixing member 1, the restraint strap 3, and the buffer member 4 are the same, and their lengths are the same.

[0034] Specifically, the fixing member 1 is a cuboid, and its length direction is the length direction of the operating room catheter and also the length direction of the patient's arm 7. The top surface of the fixing member 1 can fix the operating room catheter with a longer length, thereby realizing the fixation and bundling of multiple operating room catheters. Secondly, the side length of the restraint strap 3 is the same as the side length of the fixing member 1, and the length of the buffer member 4 is the same as its side length. When the restraint strap 3 fixes the fixing member 1 on the patient's arm 7, it can exert a pulling force on each position of the fixing member 1, so that the pressure exerted by each part on the patient's arm 7 is the same, avoiding excessive local pressure. The buffer member 4 can completely isolate its inner surface from the patient's arm 7 without affecting the fixing effect of the restraint strap 3, thereby avoiding pressure injuries.

[0035] Embodiment 2

[0036] As Figure 3As shown, this embodiment 2 also includes an integral restraint sleeve 6. The side of the restraint sleeve 6 near the patient's arm 7 does not completely cover the buffer 4. The remaining area of ​​the restraint sleeve 6 that does not cover the buffer 4 forms a detachable connection structure with the opposite side of the side.

[0037] Specifically, the restraint sleeve 6 is an integral structure, with its left side region bonded and fixed to the buffer 4. The size of its left side region can surround the patient's arm 7, allowing the buffer 4 to surround the patient's arm 7, thereby isolating the restraint sleeve 6 from the patient's arm 7 and preventing pressure injury.

[0038] Secondly, both the outer surface of the left side region of the restraint sleeve 6 and the inner surface of the right side region of the restraint sleeve 6 are provided with Velcro or adhesive structures with adhesive function, so that after the left side region of the restraint sleeve 6 wraps around the patient's arm 7, the inner surface of its right side region can fit against the outer surface of its left side region, thereby achieving a detachable connection and fixing the restraint sleeve 6.

[0039] Furthermore, the fastener 1 is connected to the side of the restraint strap 3 away from the patient's arm 7, and the side of the fastener 1 away from the patient's arm 7 forms a structure for fixing the operating room catheter that can be glued and separated.

[0040] Specifically, the bottom surface of the fastener 1 is fixedly connected to the outer surface of the restraint strap 3, so that the operating room catheter can be fixed to the restraint strap 3; secondly, the top surface of the fastener 1 can fix the operating room catheter through adhesive force, or it can clamp the operating room catheter to the restraint strap 3 through a relatively locking structure, so that medical staff can quickly change the operating room catheter and quickly fix the operating room catheter through the fastener 1.

[0041] Furthermore, the fastener 1 is a Velcro 61 fixedly connected to the restraint strap 3. The Velcro 61 can clamp the operating room catheter and fix it to the restraint strap 3, or the fastener 1 forms an adhesive surface 62 with a certain adhesive force.

[0042] Specifically, one side of the Velcro 61 is fixedly connected to the outer surface of the restraint strap 3, and the other side can clamp the operating room catheter and fix it to the restraint strap 3; secondly, the adhesive surface 62 can also fix the operating room catheter to the restraint strap 3 by adhesive connection, so that medical staff can quickly change the operating room catheter and quickly fix the operating room catheter by Velcro 61 or adhesive surface 62.

[0043] Furthermore, both Embodiment 1 and Embodiment 2 also include a label 5 associated with the operating room catheter, which indicates the type of operating room catheter associated with it, such as an invasive hemodynamic monitoring catheter, an intravenous catheter for delivering anesthetic drugs, and a blood oxygen saturation monitoring catheter.

[0044] Specifically, label 5 is a writable piece of paper that can be pasted onto the top surface of fixture 1. Medical staff use label 5 to identify different functions of operating room catheters. This facilitates the observation of the flow of each operating room catheter by medical staff. In the event of accidental detachment of an operating room catheter, medical staff can quickly return the detached catheter to its original position and handle the corresponding medical accident by observing the corresponding label 5. Furthermore, medical staff can quickly identify the operating room catheter in use by using label 5, and then replace it with an operating room catheter of other functions, thereby improving the efficiency of the operation.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
