Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical catheter fixation technology, and in particular to an epidural catheter fixation device to prevent catheter dislodgement. Background Technology
[0002] Epidural analgesia is commonly used for postoperative pain management. After surgery, the anesthesiologist connects the anesthesia pump to the epidural catheter, and then administers analgesic drugs to the patient at regular intervals and in measured doses. It is a continuous, long-acting form of anesthesia. Epidural analgesia is a recognized safe, effective, and comfortable method of postoperative pain management, and it has advantages in major surgeries for high-risk patients such as pregnant women and the elderly. However, due to limitations such as the thinness of the epidural catheter, inconvenience in fixation, and its tendency to dislodge and shift, it often fails to guarantee analgesia for 48 hours or longer, or even results in no analgesia at all. This is detrimental to patient recovery, affects the patient's medical experience, and wastes medical resources.
[0003] Currently, epidural catheters are typically secured directly with adhesive tape. However, over time, the tape's adhesiveness decreases, making it prone to detachment. This can lead to catheter dislodgement, preventing accurate drug injection and affecting analgesic efficacy. Furthermore, the lack of a drying mechanism means that patient sweating can further shorten the lifespan of the fixation device. Therefore, those skilled in the art have developed an epidural catheter fixation device to prevent catheter dislodgement and address the problems described in the background section. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an epidural catheter fixation device to prevent catheter dislodgement. The device is secured with adhesive tape and further secured with elastic bands and Velcro to prevent catheter dislodgement. A drying mechanism is also provided on the lower base to dry and absorb sweat and moisture, increasing the lifespan of the epidural catheter fixation device. This device has a simple structure and is easy to use.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an epidural catheter fixation device for preventing catheter dislodgement, comprising a lower base, buckles fixedly provided on both sides of the lower base, elastic bands wound around the surfaces of the two buckles, a female hook and loop fastener fixedly provided on the upper end face of one of the two elastic bands, a female hook and loop fastener fixedly provided on the lower end face of one of the two elastic bands, two drying mechanisms fixedly provided on the upper end face of the lower base, a hinge fixedly provided on one side of the lower base, and an upper base fixedly provided on the other side of the hinge.

[0024] Specifically, elastic bands 11 are provided on both sides of the lower base 3. The elastic bands 11 are wrapped around the patient's body and are fixed by using the female hook and loop fastener 8 and the female hook and loop fastener 10. A drying mechanism 14 is provided at the upper end of the lower base 3 to dry and absorb moisture, thereby increasing the service life of the fixing tape 1.
[0025] A flexible pad 2 is fixedly provided on the lower end face of the lower base 3, and a fixing tape 1 is fixedly provided on the lower end face of the flexible pad 2;
[0026] Specifically, the epidural catheter fixation device is initially fixed to the body surface by using the fixation tape 1 to adhere to the skin. A flexible pad 2 is placed on the upper end of the fixation tape 1 to increase comfort.
[0027] A glass plate 6 is fixedly installed on the upper end face of the upper base 4, and elastic pads 7 are fixedly installed on the upper end face of the lower base 3 and the lower end face of the upper base 4.
[0028] Specifically, during the use of the epidural catheter fixation device, the catheter is fixed between two elastic pads 7. The elastic pads 7 fix the catheter to prevent it from being squeezed and deformed, which would affect the flow rate and volume of the sedative inside the catheter and thus affect the analgesic effect. The elastic pads 7 are made of transparent polyurethane elastomer. At the same time, a glass plate 6 is set on the upper end of the upper base 4. The condition of the catheter can be observed in real time through the glass plate 6 and the elastic pads 7, so as to adjust the position of the catheter and the flow rate and volume of the sedative inside the catheter according to the actual situation.
[0029] A latch 13 is fixedly installed on one side of the lower base 3, and a lock head 12 is fixedly installed on the same side of the upper base 4;
[0030] Specifically, by using the locking head 12 and the locking buckle 13, the upper base 4 and the lower base 3 can be fixed after the conduit is placed, preventing them from falling off during use and causing the conduit to fall off.
[0031] The upper surface of the upper base 4 has multiple ventilation holes 15, and a filter screen 16 is fixedly installed inside the multiple ventilation holes 15.

[0034] Specifically, the drying mechanism 14 is composed of an absorbent layer 1401, a drying layer 1402, and a breathable layer 1403. The absorbent layer 1401, made of sponge, can absorb moisture in the air and prevent moisture from entering the interior of the epidural catheter fixation device, thus affecting the adhesion of the fixation tape 1 and increasing the service life of the fixation device. At the same time, the drying layer 1402, made of silica gel desiccant, and the breathable layer 1403, made of spandex, are provided to absorb and dry the sweat and moisture produced by the human body, further increasing the service life of the epidural catheter fixation device.
[0035] Working principle: Fixing tape 1 is set at the bottom of the epidural catheter fixation device. The fixing device is attached to the catheter by fixing tape 1. Elastic bands 11 are set on both sides of the lower base 3. The elastic bands 11 are wrapped around the patient's body. The elastic bands 11 are attached to the front of the body by the daughter hook and loop fastener 10 and the mother hook and loop fastener 8 to further fix the epidural catheter fixation device and prevent the catheter from falling off.

The absorbent layer 1401 absorbs moisture in the air to prevent moisture in the air from affecting the service life of the fixing tape 1. The breathable layer 1403 and the drying layer 1402 absorb and dry the sweat and moisture produced by the human body to prevent a large amount of sweat from reducing the stickiness of the fixing tape 1 and affecting the service life of the epidural catheter fixation device.
[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
