Description

Catheter fixation band

BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a catheter-fixed medical device, and more particularly to a fixation device for securing a medical catheter to a patient to prevent movement of the catheter relative to the patient. Background technique

Often, some patients have to lie in bed and cannot walk around because of their own disease or treatment needs, such as some patients after surgery. In this case, the FOLEY catheter is usually used to excrete urine or some special postoperative bladder effusion/blood. The bladder-to-external access established by a special three-lumen catheter can achieve regular bladder irrigation to meet the patient's treatment needs, improve patient comfort, and restore health better and faster.

Typically, the FOLEY catheter is a flexible hose made of silicone or natural latex that contains two or three coaxial tubing: an inflation tube, a drain tube and/or a flush tube. Wherein the urinary catheter has one or more openings near the bladder end to expel urine, body fluids or blood from the bladder through a collection container (e.g., a negative pressure urine bag) connected to the distal end of the urinary catheter. The proximal end of the inflation tube communicates with an air bag, and the distal end is connected with an inflation valve to facilitate the medical personnel to fill the air bag with air or liquid (such as physiological saline) through the air valve, and the inflated air bag can prevent the catheter from being blocked. Accidental release from the bladder occurs. Typically, the inflation valve branch of the distal bladder end of the FOLEY catheter, the catheter branch of the catheter and the body of the catheter form a "Y"-like structure. Since the safety and effectiveness of the FOLEY catheter has been clinically proven for many years, it is currently widely used in all types of medical institutions for applicable patients.

In the actual use of the FOLEY catheter, the patient may need to move or the medical staff needs to adjust the catheter, replace the collection container (such as the urine bag), or perform a bladder irrigation operation, which may cause the catheter tube outside the urethra. The body is folded or twisted to cause blockage. It may also cause traction of the catheter, which may cause the tube to rub against the bladder of the urethra or catheter at the end of the catheter, causing mucosal congestion, damage, and even infection. Therefore, it is of great clinical significance to effectively fix the FOLEY catheter tube outside the urethra.

Conventional methods of fixing the FOLEY catheter include attaching the tube to the skin of the thigh using a simple medical tape, or wrapping the tube around the thigh or bedside bracket using gauze, bandages, and the like. These simple fixing methods are not effective in fixing the pipe body, preventing the pipe body from moving particularly in the longitudinal direction, and are also inconvenient to operate. There are also a number of specialized FOLEY catheter fixation devices that use a hook and loop fastener to secure the catheter tube directly, as disclosed in U.S. Patent No. 5,941,856. However, this patent effectively fixes the catheter tube body to prevent the movement of the longitudinal axis from at least partially compressing the tube body, and thus affecting the inner diameter of the catheter to varying degrees (depending on the skill and strength of the operator locking the strap) May affect the discharge of urine through the body, may cause discomfort, and even infection. There are also some specially designed medical stickers for use in FOLEY catheter fixation, such as the US patent USD608, 887 Open. This patent is designed to be attached to the patient's thigh skin by a bottom adhesive tape, and the catheter tube is secured to the underlying adhesive tape by a second layer of adhesive attached to the bottom adhesive tape. This design with adhesive tape can effectively fix the pipe body and also reduce the deformation caused by the extrusion of the pipe body. However, there are many disadvantages to attaching the underlying adhesive tape directly to the skin. For example, it may cause allergies, it is inconvenient to adjust the position, it is easy to accumulate dust bacteria, the skin pulled by the adhesive strip is pulled, the hair is torn and the pain is caused, the patient sweats, etc. Causes the patient to wear uncomfortable.

Therefore, there is a need for a simple fixing device for fixing the catheter to the patient safely and effectively, without affecting the diameter of the catheter and the function of guiding the catheter, facilitating the adjustment of the catheter by the medical staff, changing the urine bag or performing urinary tract irrigation. At the same time, the patient is comfortable to wear and does not affect the patient's small movement. It is more suitable for mass production, material safety, low cost, and is suitable for a wide range of clinical applications. Summary of the invention

The object of the present invention is to provide a catheter fixing strap, which is particularly suitable for fixing a FOLEY catheter to a patient's thigh for more comprehensive safety, convenient operation, firm fixation, easy removal, easy processing, low cost, and patient Wear comfort and other requirements.

To achieve the above object, a catheter fixing belt of the present invention comprises an elastic band, a connecting fixing piece fixed to one end of the elastic band, and an opening fixing piece of the opening. The elastic band can be fixed around the patient's limbs, such as the thigh, by a connecting piece fixed at one end. The buckle fixing piece of the opening may be a hook-and-eye fastener piece or a single-sided hook fastening piece, one end is fixed on the upper surface of the elastic band, and the other end is suspended and can be folded to the same side of the hook. The fixing piece is fixed to the elastic band portion or directly to the surface of the elastic band, and the releasable connection is fixed by the hook-and-hair hook connection of the hook hair or the single-sided hook connecting with the surface of the elastic band. For specific use, the inflation end valve of the FOLEY catheter can be branched through the opening of the hook-floating fastener or the single-sided hook fastener, and then the hook of the suspended portion is fastened with the same surface. The sheet or the single-sided hook fastener fixing piece is folded to the corresponding portion of the elastic belt or directly folded toward the surface of the elastic belt, and is directly releasably connected to the surface of the elastic belt by the hook connection or the single hook fastener, and further The "Y"-shaped structure formed by the catheter joint branch of the catheter, the catheter tube body and the inflation valve branch is fixed on the elastic band to fix the catheter to the patient's thigh.

The catheter fixation device of the present invention is particularly useful for securing a FOLEY catheter to the patient's thigh. The simple structure facilitates processing and reduces costs. At the same time, the present invention utilizes an elastic band to be fixed to the limbs of the patient, such as the thigh, to avoid the discomfort caused by the allergy or removal caused by the adhesive directly applied to the skin. By using the "Y"-type structure of the FOLEY catheter, the catheter can be effectively fixed in the circumferential direction and the axial direction, and the deformation of the tube body caused by the tube body fixation can be avoided. The elastic band combined with the fastening method of the buckle fixing piece is convenient to release and repeatedly fixed, which is beneficial to adjust the fixing position and the treatment operation of the medical staff.

In particular, the inventive novel uses a non-woven elastic band surface mount buckle fixing piece as a main structure to fix the FOLEY catheter. The non-woven elastic belt is light, breathable and easy to process. It is easy to realize multi-layer composite processing by ultrasonic or rubber coating. It can realize the direct composite processing method which is difficult to realize by traditional braided elastic belt, reducing cost and facilitating large-scale processing. Promote use. The catheter fixing device of the invention has the advantages of safety, reliability, ease of use, convenient adjustment, comfortable wearing, easy processing, low cost and the like. DRAWINGS
