Description

Technical Field

[0001] The utility model relates to the technical field of medical treatment, in particular to a medical blood fistula protector for patients with upper arm arteriovenous fistula dialysis accompanied by agitation who need protective restraint. Background Art

[0002] Nowadays, the number of patients with kidney disease increases year by year, and blood fistula has become the choice of many patients as a common blood purification route. Kidney disease accumulates in multiple organs, and many patients need to be hospitalized as time progresses. Many patients may experience mental symptoms and become agitated. Due to the doctor-patient ratio and other reasons, hospitals cannot guarantee 24-hour monitoring of patients. For these agitated patients, especially those with multiple indwelling tubes, protective restraint is necessary to avoid unplanned extubation.

[0003] The existing technology often uses Figure 5 The restraint belt shown restrains the patient's wrist. The restraint belt is provided with a rough Velcro 2' on one side of a base fabric 1' of a certain length and width, and a wrist fixing belt 5' is provided on the base fabric and the rough Velcro. An iron ring is provided at one end of the wrist fixing belt 5' for the other end to be drilled through as a fixing ring 4' to provide the function of adjusting its tightness, and Velcro is provided at the other end of the wrist fixing belt. A part of the transverse fixing belt 3' is sewn below the rough Velcro or wrist fixing belt and above the base fabric to provide the function of limiting the patient's range of motion. When in use, the base fabric of the restraint belt is placed on the patient's wrist and formed into a circle, and the other end of the wrist fixing belt is drilled into the fixing ring. After adjusting the tightness, it is folded after being wrapped around the central iron sheet of the fixing ring, and affixed to the rough Velcro on the base fabric. Then the transverse fixing belt is bolted to the bed guard to limit the patient's range of motion.

[0004] The above-mentioned restraint belt can only restrain the patient's wrist and cannot limit the movement of the upper arm. Agitation patients with greater strength or a large range of movement can directly throw off or destroy the restraint belt. In order to avoid unplanned extubation, the only way is to increase the restraint force. For patients with fistulas, excessive external pressure may cause damage to the fistula function. The fistula of some patients is close to the wrist. In order to reduce fistula pressure and avoid affecting the fistula function, it is impossible to restrain the wrist on the fistula side, or the force is not enough to restrain the patient's activities. When the patient is agitated, unplanned extubation and accidental injury may occur, causing certain health and economic losses to the patient. If necessary, personnel are required to continuously accompany and inspect the patient, which consumes a lot of manpower. In addition, the materials used in existing restraints are not soft and skin-friendly enough, and are prone to skin abrasion and pressure injuries at the restraint site; the restraints are fixed using Velcro and tethers, and the suturing method is rough, and the Velcro is easily damaged after long-term use; the metal fixing rings are poorly selected and cannot be removed or replaced. After long-term use, they deform and rust after cleaning, and the restraint effect cannot be guaranteed; the restraints are of a single model, and too thin patients can still escape from them when the restraints are pulled to the tightest, and the Velcro fixing belts of overweight patients are not long enough, and the folded part is short, and the fixing force cannot be achieved; the horizontal fixing belt of the restraint belt is of a single length, which cannot be adapted to the use of each bed unit, and there is too much remaining length that needs to be repeatedly wrapped, or the length is insufficient, the patient's range of motion is too small, and the patient feels uncomfortable.

[0005] In addition, due to the particularity of the patient's blood fistula physiological structure, it cannot be compressed by external force, and the blood fistula site needs to be exposed during the blood purification treatment. However, there are currently no restraint tools with the above functions for patients with blood fistula on the market. Summary of the invention

[0006] The purpose of the utility model is to solve the above-mentioned problems and to provide a medical blood fistula protector with a simple structure and easy use.

[0025] like Figure 1 , Figure 3 As shown, there are two different structural schematic diagrams of the medical fistula protector provided by the utility model. It can be seen from the figure that the medical fistula protector of the utility model comprises: a sleeve 2 for being put on the outside of the patient's fistula-side arm; an upper adjustment belt 1 and a lower adjustment belt 5 respectively arranged at the upper end and the lower end of the sleeve for adjusting the tightness of both ends thereof; a fixing plate 4 fixedly installed on one side of the sleeve; two fixing belts 3 detachably connected to the fixing plate and whose positions on the fixing plate can be adjusted.

[0026] Specifically, Figure 4 As shown, the sleeve of the utility model is in the shape of a cone that gradually narrows from top to bottom. It is a sleeve made of pure cotton material. When manufacturing, sleeves of different sizes can be processed. The length of each sleeve can cover the upper arm from the wrist to the elbow or slightly above the elbow. When using, the patient can choose a suitable model according to the location of the fistula and the body shape. Elastic bands are sewn on the upper and lower ends of the sleeve respectively. The sleeve can be fixed on the arm after being put on the patient's fistula-side arm through the elastic band. The length of the elastic band needs to be reasonably selected to make the tightness appropriate.

[0027] An observation window 8 is provided on the side wall of the sleeve for easy observation, and a transparent cover 6 detachably connected to the sleeve is placed at the observation window. During manufacturing, part of the material on one side of the sleeve is cut off to form the observation window, a circle of Velcro sub-stickers or sub-velcro is sewn or pasted at the position around the observation window on the sleeve, and a circle of Velcro mother stickers or mother velcro is pasted around the transparent cover slightly larger than the observation window, so that the transparent cover can be fixed to the observation window of the sleeve by Velcro or velcro as needed. The transparent cover is made of transparent material, such as transparent plastic, and a slightly hard transparent plastic film can be used.

[0028] A fixing plate is also fixed on the side wall of the sleeve, located beside the observation window. The length of the fixing plate is slightly smaller than the length of the sleeve. The fixing plate can be made of hard material, such as a thin plastic plate, which can be sewn on the sleeve or glued to the sleeve.

[0029] In order to fix the medical fistula protector of the utility model at a desired position, such as on a bed rail, two fixing straps are detachably mounted on the fixing plate, which can adjust the position relative to the fixing plate as needed. For example, a plurality of adjustment holes can be provided on the fixing plate (see Figure 1 ), the two fixing belts are respectively installed at any two or two pairs of the multiple adjustment holes. During installation, the middle of the fixing belt can be fixed to the adjustment hole of the fixing plate by bolts 9 (see Figure 2Alternatively, a slide groove 10 may be provided on the outer wall of the fixed plate, and a slider 11 that can slide in the slide groove is fixed in the middle of the fixed belt (see Figure 3 ), a limit piece (not shown in the figure) is provided on the slider for locking it at any position of the slide slot, and the limit piece can be a bolt or a screw, which can pass through the fixing belt and be screwed into the slider and then extend into the slide slot and abut against the inner wall of the slide slot, so that the slider can be locked at this position of the slide slot, and then the fixing belt can be locked at this position.

[0030] Furthermore, the medical fistula protector of the utility model further comprises a snap-on adjustment belt 7 arranged on the upper end of the sleeve near the fixing plate.

[0031] When in use, the patient's fistula-side arm is inserted into the sleeve from top to bottom, so that the upper end of the sleeve is located at the elbow or above the elbow, and the lower end of the sleeve is at the wrist. The tightness of the snap-on adjustment belt and the elastic band is adjusted according to the fatness of the patient's arm, so that the observation window in front of the sleeve is located on the outside of the arm. According to the patient's comfort and treatment needs, determine the appropriate position to install the fixing belt on the hard fixing plate, and then tie the fixing belt to the appropriate position of the bed rail. The fistula can be exposed through the observation window in front of the sleeve to facilitate treatment. When the puncture is completed and the machine is connected, the transparent film can be fixed at the observation window so that the fistula condition can be observed at any time through the transparent film.

[0032] In summary, the medical fistula protector of the utility model has a sleeve made of soft, skin-friendly and breathable cotton material, which can be repeatedly cleaned and disinfected to reduce the abrasion and pressure injury of the skin of a restless patient; the upper and lower ends of the sleeve are provided with a detachable elastic band and a snap-on adjustment band with adjustable tightness, and the sleeve can be ensured to have appropriate tightness when it is sleeved on the outside of the patient's fistula-side arm, and when the fistula is too high or too low, the sleeve can still be fixed above or below; the hard fixed plate with holes arranged on one side of the sleeve can be used in conjunction with movable fixed belts of different lengths, and the fixed position can be adjusted according to the patient's arm condition and surrounding facilities to ensure the restraint effect, and the hard fixed belt avoids the fixed belt from directly applying pressure to the patient's fistula-side arm, thereby improving comfort and reducing the occurrence of damaged fistula function under pressure; an observation window is provided on the sleeve, which is convenient for operation when the fistula is used for blood purification and other treatments, and the observation window is equipped with a detachable antibacterial and durable transparent cover (which can be a transparent film), which can be pasted to protect the fistula site when necessary. Different models can be set during manufacturing, and the length can cover the upper arm from the wrist to the elbow or above the elbow as needed, so that patients can choose a suitable model according to the location of the fistula and body shape.

[0033] Although the utility model is described in detail above, the utility model is not limited thereto, and technicians in this technical field can make modifications based on the principles of the utility model. Therefore, all kinds of modifications made according to the principles of the utility model should be understood to fall within the protection scope of the utility model.
