Description

Improved cold-proof comfortable pillow for internal arteriovenous fistula

Technical Field

The utility model belongs to the field of comfortable pillows, and particularly relates to an improved cold-proof comfortable pillow for arteriovenous fistula.

Background

Uremic patients require long-term hemodialysis treatment because their kidney function has been lost and metabolic waste and excess fluid in the body cannot be removed by themselves. For these patients, arteriovenous internal fistulae are an important means of hemodialysis that surgically connects an artery and a vein together to form a high flow, high pressure vascular access. This pathway is called the "lifeline" of the patient, as it provides a stable and adequate blood flow for hemodialysis, directly related to the effect of the treatment and the quality of life of the patient.

During hemodialysis, the patient needs to go 2 to 3 times per week for about 4 hours. Such frequent and prolonged treatments place high demands on the patient's body. Due to the different trend and anatomy of the blood vessels of each individual, the healthcare worker needs to select the appropriate puncture site according to the specific situation. After the arteriovenous fistula puncture is successful, the patient's arm must remain in a fixed position for a long period of time in order to ensure successful dialysis. This fixed posture is mainly to prevent the puncture needle from slipping off and to ensure that blood can flow continuously and stably into the dialysis machine.

However, maintaining a fixed posture for a long period of time, coupled with the cold weather, may have adverse effects on the patient's blood circulation and nervous system. Firstly, the arm is fixed for a long time, local muscles are continuously pressed, and blood backflow is easy to cause, and local blood supply is insufficient. This condition can lead to the patient feeling soreness, heaviness, and even tingling. In addition, resting posture may cause the nerves to be compressed, further exacerbating discomfort, and causing paresthesia such as numbness or tingling.

This situation may be more pronounced in cold weather. The low temperature can cause vasoconstriction, blood flow is slower, and the soreness and numbness of the arms are further aggravated. At the same time, cold stimulation may also trigger a response to the sympathetic nervous system, leading to systemic vasoconstriction, increased heart rate, and increased blood pressure. For patients already suffering from uremia, elevated blood pressure is a dangerous condition, possibly increasing the risk of cardiovascular events.

The present utility model has been made in view of this.

Referring to fig. 1-5, in this embodiment, an improved cold-proof comfortable pillow for arteriovenous fistula is provided, which comprises a lower pad part 1 and an upper pad part 2 connected by a zipper, wherein the upper pad part 2 and the lower pad part 1 are combined to form a pocket-shaped structure, an inflatable bag 3 is arranged below an opening of the pocket-shaped structure, a pressing component is arranged above the inflatable bag, a plurality of fixing belts 4 are fixedly connected to the lower pad part 1 from the opening to the bottom in sequence, the fixing belts 4 are fixedly connected to two sides of the edge of the upper pad part 2, a PVC glass soft transparent film 5 is arranged on one side, far away from the lower pad part 1, of the upper pad part 2, and the PVC glass soft transparent film 5 can effectively cover the arm of a patient, so that an additional warm-keeping function is provided in the dialysis process. During hemodialysis, the patient typically needs to maintain the arm exposed for a long period of time, which can lead to localized temperature reductions in the arm, particularly in cold environments. Such low temperatures not only cause discomfort to the patient, but may also cause muscle stiffness and vasoconstriction due to cold, increasing the difficulty and risk of the dialysis procedure. The soft transparent film 5 can keep the temperature of the arm like a heat insulation layer, and avoid cold air from directly contacting the skin, thereby providing comfortable warm-keeping effect for patients.

Secondly, the design of the transparent film 5 greatly facilitates the inspection and observation of the arms and the arteriovenous fistula of the patient by medical staff in the dialysis process. Due to the transparency of the material, nurses can clearly see the conditions of the covered arms and dialysis pipelines, and timely find any abnormality, such as the movement of the needle head position, the change of local skin or the occurrence of blood seepage. The design avoids the operation of frequently uncovering the cover checking arm, not only simplifies the nursing process and improves the working efficiency, but also reduces the interference to the patient and reduces the infection risk.

By combining the warm keeping function and the transparent observation function, the PVC soft transparent film 5 can effectively reduce the occurrence rate of early shutdown due to the reduction of patient tolerance caused by cold. During hemodialysis, the patient often needs to remain stationary for a long period of time, and the cold sensation can increase discomfort, even causing the patient to stop dialysis midway due to intolerance. The warmth retention effect of the transparent film 5 helps to improve the overall tolerance of the patient and reduce the occurrence of premature machine-down, thereby ensuring the integrity of the dialysis treatment course and the therapeutic effect.

In this embodiment, the pressing component includes a pressing inflation valve 6 disposed on the inflation bag 3, a one-way valve 7 is disposed on an air inlet of the pressing inflation valve 6, and an air outlet of the pressing inflation valve 6 is communicated with the inflation bag 3.
