Abstract
Description
Technical Field
[0001] This utility model relates to the field of catheter fixation device technology, and in particular to a medium-length catheter protection device. Background Technology
[0002] The midline catheter is 20-30 cm long and is inserted into important veins, such as the cephalic vein and brachial vein, through a routine puncture two finger-widths above and below the elbow crease in the forearm, or using ultrasound guidance. The catheter tip is positioned in the thoracic segment of the axillary vein or even reaches the subclavian vein. The catheter can be left in place for up to 49 days. The advantages of this catheter include reducing repeated punctures, alleviating patient discomfort, and increasing patient confidence in treatment.
[0003] Under current technology, improper care of medium- and long catheters, such as insecure dressing fixation or inadequate restraint of agitated patients, can lead to patients with cognitive impairment or agitation pulling out the catheter on their own. Unplanned extubation not only affects the patient's continued treatment, but also increases the patient's physical and mental suffering and financial burden due to re-insertion. Utility Model Content
[0004] The purpose of this invention is to provide a protection device for medium-length catheters to solve the problem of inadequate catheter fixation and constraint mentioned in the background art.
[0005] To solve the above problems, the technical solution adopted by this utility model is as follows:
[0006] A medium-length catheter protection device, comprising
[0007] A breathable elastic fabric, wherein a first window and a second window for the positive pressure connector of the conduit to pass through are provided on the breathable elastic fabric;
[0008] The first hook and loop fastener, and several of the first hook and loop fasteners are fixedly installed on one side wall of the breathable elastic fabric;
[0009] The first female hook and loop fastener, and several first female hook and loop fasteners are fixedly set on the other side wall of the breathable elastic fabric, and the first female hook and loop fasteners are connected to the first female hook and loop fasteners by adhesive.
[0010] A fixing component is disposed on one side of the second window and is used to fix the positive pressure connector.
[0011] Preferably, there are two second windows, and the two second windows are symmetrically arranged on both sides of the first window.
[0012] Preferably, the fastening component includes a second female hook and loop fastener and a second female hook and loop fastener. The second female hook and loop fastener is fixedly disposed on one side wall of the breathable elastic fabric. One end of the second female hook and loop fastener is fixedly connected to one end of the second female hook and loop fastener, and the second female hook and loop fastener are connected by adhesive.
[0013] Preferably, it also includes a plurality of third female hook and loop fasteners disposed around the periphery of the first window, and one side wall of each of the plurality of third female hook and loop fasteners is fixedly connected to one side wall of the breathable elastic fabric. A compression pad is provided on one side of the first window, and a plurality of third female hook and loop fasteners are fixedly connected around the periphery of the compression pad. The third female hook and loop fasteners are connected to the third female hook and loop fasteners by adhesive.
[0014] Compared with the prior art, this utility model has the following advantages:
[0015] After catheter puncture, the breathable elastic fabric is wrapped around the patient's arm where the catheter was punctured. During the wearing process, the first window is positioned at the catheter puncture point, and the second window is used for the catheter positive pressure connector to pass through. The fabric is then secured by a fixing component. Subsequently, the breathable elastic fabric is secured at both ends by using the adhesive connection between the first female and first female Velcro straps. This provides a good catheter fixation effect and prevents the catheter from falling off.
[0016] On the first day of puncture, to prevent bleeding at the puncture site, medical staff can use the adhesive connection between the third hook and loop fastener to cover one side of the first window with a pressure pad to achieve hemostasis. Afterwards, when not in use, the third hook and loop fastener can be separated from the third hook and loop fastener, making the structural design user-friendly. Attached Figure Description
