Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, specifically to a catheter fixation device for patient care. Background Technology
[0002] Catheter fixation devices can effectively avoid or reduce catheter dislodgement and blockage, reduce the number of replacements, and shorten nursing time. They play an important role in promoting patient recovery and improving patient satisfaction. The demand for catheter fixation devices in hepatobiliary surgery mainly stems from the high requirements for catheter stability and safety in hepatobiliary and pancreatic surgery. Through continuous technological improvements and clinical validation, new catheter fixation devices have played an important role in improving surgical outcomes and patient satisfaction.
[0003] Existing catheter fixation devices typically use fixation tapes to secure the catheter to the patient's skin. Prolonged use can cause discomfort to the patient's skin. If the patient has more than one catheter at the wound site, the number of fixation tapes needs to be increased, which can further increase the patient's discomfort. Therefore, we propose a catheter fixation device for patient care. Utility Model Content
[0004] To address the shortcomings of existing technologies, this invention provides a catheter fixation device for patient care, which solves the problems mentioned in the background section.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a catheter fixation device for patient care, comprising a strap, a buckle box fixedly installed at one end of the strap, a slot provided inside the buckle box, a rotating shaft rotatably connected to the top of the buckle box, a fixing plate fixedly installed on the outside of the rotating shaft, and several spurs fixedly installed at the bottom of the fixing plate. One end of the rotating shaft passes through one side of the buckle box and is fixedly connected to an adjusting knob. Several moving blocks are slidably connected to the outside of the strap, a first patch is fixedly connected to the top of the moving blocks, a connecting film is fixedly installed at the top of the first patch, a second patch is fixedly connected to one side of the connecting film, a third patch is fixedly connected to the other side of the connecting film, and a clamping tube is fixedly installed at the top of the connecting film. When it is necessary to install this device on the patient's thigh, the spurs are simply inserted into the strap to fix the device on the patient's thigh.
[0006] Preferably, the top ends of the first, second, and third adhesive films are respectively fixedly connected with a first adhesive layer, a second adhesive layer, and a third adhesive layer. By utilizing the cooperation between the first, second, and third adhesive layers, the conduit can be fixed inside the clamping tube.
[0007] Preferably, a number of rubber strips are fixedly installed on the inner side of the clamping tube.
[0008] Preferably, the strap has several ventilation holes inside.
[0009] Preferably, a peel-off layer is provided at the top of the first adhesive layer, the second adhesive layer, and the third adhesive layer.
[0010] This utility model provides a catheter fixation device for patient care, which has the following beneficial effects:
[0011] 1. This patient care catheter fixation device, through the setting of the buckle box, when it is necessary to fix this device to the patient's thigh, one end of the strap is inserted into the slot, and then the buckle is inserted into the inside of the strap, thereby fixing the device to the patient's thigh. This process avoids the patient's discomfort with the fixation patch, and the setting of ventilation holes will not make the patient feel stuffy.
[0012] 2. This patient care catheter fixation device, through the setting of movable blocks, can increase the number of movable blocks on the strap according to the number of catheters on the patient. This process setting allows several movable blocks to be installed on the strap, thereby fixing several catheters. Attached Figure Description

Detailed Implementation
[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] Please see Figures 1 to 6 This utility model provides a technical solution: a catheter fixation device for patient care, including a strap 1, a buckle box 2 fixedly installed at one end of the strap 1, a slot 201 opened inside the buckle box 2 for the other end of the strap 1 to pass through, a rotating shaft 5 rotatably connected to the top of the buckle box 2, a fixing plate 3 fixedly installed on the outside of the rotating shaft 5, a plurality of spurs 4 fixedly installed at the bottom of the fixing plate 3 for locking the strap 1, an adjusting knob 6 fixedly connected to one side of the rotating shaft 5 passing through the buckle box 2, a plurality of moving blocks 7 slidably connected to the outside of the strap 1 for adjusting the position and being installed on the strap 1, a first patch 8 fixedly connected to the top of the moving block 7, a connecting film 10 fixedly installed at the top of the first patch 8, a second patch 9 fixedly connected to one side of the connecting film 10, a third patch 11 fixedly connected to the other side of the connecting film 10, and a clamping tube 12 fixedly installed at the top of the connecting film 10 for clamping the catheter.
[0022] like Figure 3 As shown, the top ends of film 1 (8), film 2 (9), and film 3 (11) are respectively fixedly connected with a first adhesive layer 801, a second adhesive layer 901, and a third adhesive layer 111. The first adhesive layer 801, the second adhesive layer 901, and the third adhesive layer 111 are used to fix the conduit inside the clamping tube 12.
[0023] like Figure 5 As shown, several rubber strips 121 are fixedly installed on the inner side of the clamping tube 12. The rubber strips 121 are used to increase friction.
[0024] like Figure 1 As shown, the strap 1 has several ventilation holes 101 inside, which are used for ventilation.
[0025] like Figure 3 As shown, the top of the first adhesive layer 801, the second adhesive layer 901 and the third adhesive layer 111 are all provided with a peel-off film layer.
[0026] In summary, when using this patient care catheter fixation device, medical staff first determine the number of catheters at the patient's wound site, then install several movable blocks 7 on the bandage 1. After installation, the device is strapped to the patient's thigh. One end of the bandage 1 is inserted into the slot 201, and the end of the bandage 1 is pulled until it is tight. Then, the fixing plate 3 is rotated using the adjusting knob 6, which allows the piercing 4 to be inserted into the bandage 1, thus fixing the device to the patient's thigh. The movable blocks 7 are then moved to the appropriate position on the bandage 1, and the catheters on the patient can be placed on the clamping tube 12. Medical staff then proceed with the process of securing the catheters to the wound site. The films on the first adhesive layer 801, the second adhesive layer 901, and the third adhesive layer 111 are peeled off. Then, medical staff first lift the third adhesive layer 111 and pass it over the top of the clamping tube 12, so that the third adhesive layer 111 mates with the first adhesive layer 801. Then, the second adhesive layer 9 is lifted and passed over the top of the clamping tube 12, so that the second adhesive layer 901 mates with the first adhesive layer 801. In this way, the catheter can be fixed. When it is necessary to remove it, simply separate the first adhesive layer 801, the second adhesive layer 901, and the third adhesive layer 111 from each other, and then use the adjusting knob 6 to separate the spiking bar 4 from the strap 1. The above is the working principle of this utility model.
[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
