[0002] In the process of long-term catheterization of hemodialysis, in order to ensure the sterile environment of operation, medical staff usually lays a sterile drape on the head area of the patient. However, this operation mode brings several challenges and problems:
[0003] 1. Difficult breathing: the drape is covered near the face of the patient, which limits the air circulation, causing some patients to have suffocation, breathing difficulties. This situation is particularly true for hemodialysis patients who need to maintain a fixed posture for a long time to receive treatment, which increases physical discomfort.
[0004] 2. Psychological anxiety and fear: due to the effect of local anesthesia, the patient's consciousness is usually clear. When the drape is covered on the head, the limited vision can cause the patient's anxiety and fear, worrying about the operation process or unknown situations. Patients may try to move the drape with their hands or frequently turn their heads to try to get a wider field of view or feel safer.
[0005] 3. Increased risk of sterility: these actions of the patient (such as moving the head or trying to take off the drape) can increase the risk of contamination of the sterile area. Any disruption to the sterile condition can cause complications such as infection, which is particularly dangerous for hemodialysis patients with a weak immune system. INVENTION CONTENT

[0031] The following is a specific embodiment of the utility model and further describes the technical method of the utility model in combination with the drawings, but the utility model is not limited to these embodiments.
[0032] As shown in Figures 1-4 The utility model provides a fixed support for long-term catheterization of hemodialysis, comprising:
[0033] The mounting plate 100 is provided with a pair of;
[0034] The telescopic frame 110 is connected with the two mounting plates 100 at both ends respectively, and the telescopic frame 110 is riveted by a plurality of rod members and forms an expandable or retractable telescopic structure;
[0035] The support foot 120 is arranged at the bottom of the two mounting plates 100 to raise the height of the telescopic frame 110, so that the bottom of the telescopic frame 110 forms an accommodating space and is used for the patient's head to extend into, and the telescopic frame 110 is covered with a sterile hole towel to form a sterile area in the accommodating space.
[0036] It should be noted that, at present, in the process of long-term catheterization for hemodialysis, in order to ensure the sterile environment during operation, medical staff will cover the sterile drape on the head of the patient. This way, on the one hand, it will limit the patient's breathing, causing some patients to have shortness of breath, difficulty breathing, on the other hand, it will also bring psychological anxiety and panic to the patient, causing the patient to try to remove the drape with his hand or turn his head frequently, and the patient's actions are easy to contaminate the sterile area.
[0037] To solve this problem, the embodiment provides a fixing support for laying sterile drape, which is erected on the head of the patient by the fixing support, and then the sterile drape is laid on the fixing support, thereby solving the above problems.
[0038] Specifically, the fixing support brings at least the following advantages:
[0039] 1. Improve the breathing condition: By building an open space above the patient's head, the problem of shortness of breath caused by the traditional drape directly covering the face is avoided, a more free air circulation environment is provided, and the comfort of the patient is significantly improved;
[0040] 2. Reduce anxiety and fear: Because the field of vision is no longer completely blocked, the patient can see the surrounding environment, reducing the anxiety and fear caused by limited vision, at the same time, the increase of head movement space also reduces the risk of contamination of the sterile area caused by the patient trying to remove the drape;
[0041] 3. Enhance safety and operation convenience: The hole design on the telescopic frame 110 provides convenience for the insertion of the dialysis tube, and also ensures the sterile state during the whole process, in addition, the design of the supporting feet 120 makes the fixing support can be stably placed on the bed or operating table, enhancing the overall safety and stability;
[0042] 4. Reduce the risk of infection: By covering the sterile drape on the telescopic frame 110, a relatively closed but not affecting the vision and breathing sterile area is created, effectively preventing external bacteria from entering, reducing the risk of infection, especially in patients with low immune function.
[0043] The specific structure of the telescopic frame 110 and its telescopic principle are as follows:
[0044] Preferably, the telescopic frame 110 includes a plurality of upper rod members 111 and a plurality of lower rod members 112, the upper rod members 111 and the lower rod members 112 are connected by cross riveting, forming a scissors type telescopic structure.
[0045] Further, each of the upper rod members 111 is arranged in parallel, and each of the lower rod members 112 is arranged in parallel, ensuring the consistency and stability of the structure, and further enhancing the stability of the overall structure.
[0046] The upper rod 111 and the lower rod 112 located at both sides of the telescopic frame 110 are respectively rotatably connected with the mounting plate 100.
[0047] The upper rod 111 located at a position other than both sides of the telescopic frame 110 is riveted at both ends with two lower rods 112, forming a plurality of units that can be synchronously expanded or contracted.
[0048] This design enables the telescopic frame 110 to be expanded or contracted according to actual needs, adapting to different space requirements and operating conditions, so that medical personnel can quickly adjust the width of the entire fixing support to adapt to the heads of different patients.
[0049] After use, the telescopic frame 110 can be retracted inward, greatly reducing the overall size of the device. This design not only facilitates the storage and transportation of the equipment, reduces the storage space requirement, but also speeds up the disassembly and arrangement, improving work efficiency.
[0050] Therefore, whether for daily management of medical institutions or rapid response in emergency situations, the fixing support has shown high practicality and convenience.
[0051] Preferably, the upper rod body 111 is located at the top of the lower rod body 112.
[0052] In addition, in order to make the fixing support applicable to the heads of different patients, the support leg 120 is set as an adjustable height structure, thereby flexibly adjusting the size of the space accommodated at the bottom of the fixing support. Specifically:
[0053] The support leg 120 includes a first support rod 121, a second support rod 122, and a base 123. The top of the first support rod 121 is connected with the mounting plate 100, the second support rod 122 is telescopically connected with the first support rod 121, and the base 123 is arranged at the bottom of the second support rod 122.
[0054] Among them, the telescopic structure between the first support rod 121 and the second support rod 122 can be set as a threaded connection structure or a plug-in locking structure, and the two telescopic structure implementation manners are as follows:
[0055] 1. Threaded connection structure:
[0056] The first support rod 121 is provided with an inner cavity along the axial direction thereof, and the inner wall of the inner cavity is provided with an internal thread;
[0057] The outer wall of the second support rod 122 is provided with a corresponding external thread;
[0058] In use, the second support rod 122 is inserted into the first support rod 121, and the height is adjusted through the threaded connection between the two. Rotating the second support rod 122 can easily achieve the rise or fall, so as to accurately adjust to the required height position.
[0059] 2. Plug-in locking structure:
[0060] The first support rod 121 and the second support rod 122 are connected in an upper and lower plug-in manner;
[0061] After determining the required height, use the fastener 130 (such as screws, clamps, etc.) to lock the two support rods together to prevent sliding.
[0062] Both types of telescopic structures can achieve height adjustment of the fixed support.
[0063] Preferably, the bottom of the base 123 is designed as a claw structure or a flat structure to adapt to different use scenarios and needs. These two designs each have their own characteristics and application scope:
[0064] 1. Claw structure
[0065] Enhance stability: The claw structure increases the contact points with the contact surface (such as the surface of the hospital bed) through multiple outwardly extending legs, thereby improving the stability and anti-toppling ability of the fixed support during use;
[0066] Adapt to uneven surfaces: The claw structure can better adapt to slightly uneven surfaces, as each "claw" can independently adjust its position according to the specific conditions of the surface, ensuring that each contact point can stably support the entire device;
[0067] Flexibility: This design makes the fixed support have good adaptability on different types of beds or operating tables, especially suitable for situations that require additional stability.
[0068] 2. Flat structure
[0069] Simple and easy to use: The flat structure design is more concise, easy to clean and maintain, and it provides a larger contact area, which helps to evenly distribute the weight and reduce the pressure points on the bed surface;
[0070] Suitable for flat surfaces: For those occasions that use on very flat and stable surfaces, the flat base 123 is an ideal choice, which can provide enough friction to prevent sliding while maintaining the overall device smooth.
