Abstract
Description
Technical Field
[0001] This invention relates to the field of medical devices, and in particular to a medical dialysis bed with hemodialysis function. Background Technology
[0002] Hemodialysis is primarily used in cases of acute renal failure, chronic renal failure, drug or toxin poisoning, and refractory congestive heart failure. Currently, hemodialysis machines are commonly used. The principle behind hemodialysis is the difference in concentration between the dialysate and the waste products in the patient's blood. Based on this concentration difference, waste products are filtered, adsorbed, or diffused from the blood into the dialysate through a semi-permeable membrane, thus achieving the purpose of waste removal. The dialysate has an affinity for waste products, allowing them to actively move towards the dialysate side, aiming to remove metabolic waste products from the body, maintain electrolyte and acid-base balance, and remove excess water. The purified blood is then returned to the body, completing the entire hemodialysis process.
[0003] During hemodialysis, patients may experience various complications such as muscle spasms, bleeding, and infection. If these complications are not detected and treated promptly, they can seriously impact the patient's health. For example, low blood pressure can cause dizziness, fainting, or even death; muscle spasms can cause excruciating pain, affecting the smooth progress of dialysis; bleeding can lead to excessive blood loss and anemia; and infection can worsen the patient's condition and prolong hospitalization. Alternatively, patients are prone to arm displacement and movement during hemodialysis, which can cause the dialysis needle to shift. This displacement can lead to significant blood leakage, not only worsening the patient's condition but also potentially endangering their life. Currently, avoiding these problems relies on random monitoring by medical staff or family accompaniment during dialysis. However, relying on random monitoring by medical staff or family accompaniment is not ideal. Medical staff may need to allocate attention to multiple patients, and family members may lack professional medical knowledge and nursing skills. This can result in problems during dialysis not being addressed promptly and professionally, increasing uncertainty.
[0004] Therefore, there is an urgent need for a medical dialysis bed with hemodialysis function, which can monitor the patient's condition in real time during the dialysis process to ensure the patient's safety and comfort during the dialysis process. Summary of the Invention

Detailed Implementation
[0023] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.
[0024] The following is in conjunction with the appendix Figure 1-3 The present invention will be described in further detail below.
[0025] This invention discloses a medical dialysis bed with hemodialysis function.
[0026] Reference Figure 1 , Figure 2 , Figure 3 A medical dialysis bed with hemodialysis function includes a bed body 1, monitoring equipment and terminal equipment installed on the bed body 1. The monitoring equipment includes a first monitoring device for monitoring the patient's upper body area and a second monitoring device for monitoring the patient's dialysis site. The first and second monitoring devices are used to transmit real-time captured images to the terminal equipment. During hemodialysis, the patient's hemodialysis is monitored by the first monitoring device for monitoring the patient's upper body area and the second monitoring device for monitoring the patient's dialysis site. This allows for observation of the patient's mental state and vital signs during the hemodialysis process, helping medical staff to promptly detect and handle any abnormalities, ensuring the patient's safety and avoiding dangers caused by the absence of medical personnel.
[0027] In this embodiment, the monitoring device includes a movable frame 7, a connecting plate 8, and a monitoring component 9. The movable frame 7 is rotatably mounted on the bed body 1. The connecting plate 8 is mounted on the movable frame 7 and has a clamping assembly 10 for holding entertainment equipment. The monitoring component 9 is mounted on the connecting plate 8, allowing the monitoring device to be flexibly installed on the bed while providing the patient with the function of holding entertainment equipment. The monitoring component 9 focuses on monitoring the vital signs of the patient's upper body. The monitoring component 9 uses a high-definition camera and a vital sign monitoring radar. The high-definition camera monitors the patient's real-time video footage and changes in vital signs in the upper body. Through the high-definition camera, medical staff can clearly observe the patient's facial expressions, limb movements, and overall condition, thereby determining whether the patient is conscious and whether there are any abnormal behaviors or reactions. The vital sign monitoring radar monitors the patient's heart rate, respiratory rate, and other vital signs in real time to ensure the safety and effectiveness of the hemodialysis process.
[0028] The second monitoring device includes a sliding frame 11 and a monitoring component 12. The sliding frame 11 is slidably mounted on the bed body 1 along its length. The monitoring component 12 is mounted on the sliding frame 11 and is used to monitor the position of the patient's dialysis arm and dialysis needle. This dedicated monitoring allows the second monitoring device to flexibly follow the patient's position changes on the bed, ensuring continuous and accurate monitoring of the dialysis arm and needle. Precise monitoring of the patient's dialysis arm and needle position is crucial during hemodialysis, helping to promptly detect and address any potential abnormalities, thereby ensuring the safety and effectiveness of dialysis treatment.
[0029] In this embodiment, an arm fixation device is also provided, which includes an elbow joint fixation component 2 for fixing the patient's elbow joint and a wrist joint fixation component 3 for fixing the patient's wrist joint. The elbow joint fixation component 2 has an adsorption part for adsorbing the skin near the patient's elbow joint, and the wrist joint fixation component 3 has a fixation part for fixing the patient's palm. During hemodialysis, fixing the patient's palm and elbow joint facilitates puncture and ensures the stability of the dialysis process. During dialysis, the patient needs to remain relatively still to avoid traction or compression of the vascular access, which could affect the dialysis effect. Fixing the palm and elbow joint can effectively reduce arm movement, ensure the stability and safety of the dialysis process, and ensure that dialysis treatment can be carried out smoothly.
[0030] The bed body 1 is equipped with an arm placement device, which has a placement cavity for accommodating the patient's arm. The placement cavity has a track along the length of the arm. The elbow joint fixation component 2 includes a sliding seat 25, an air source, and an adsorption component 23. The sliding seat 25 is equipped with an adsorption component 23 for adsorbing the skin near the patient's elbow joint to form an adsorption part. The trachea is connected to the air source for air extraction. The sliding seat 25 is slidably fitted onto the track in a lockable manner.
[0031] In this embodiment, the suction element 23 is a suction cup with an added sponge. The sponge is provided in the part of the suction cup that contacts the patient. On the one hand, it can increase comfort. The soft texture of the sponge can reduce the direct pressure of the suction cup on the patient's skin and improve the comfort of use. On the other hand, it can improve the sealing performance. Due to its softness and plasticity, the sponge can make good contact with the patient's skin surface, thereby maintaining a better sealing effect and ensuring that the suction cup can be firmly attached to the patient and is not easy to fall off.
[0032] Multiple sliding seats 25 are arranged along the length of track one, and adjacent sliding seats 25 are slidably connected to each other in a lockable manner. Specifically, the sliding seats 25 include sliding seat 25-1, sliding seat 25-2, and sliding seat 25-3. Sliding seat 25-1 is used to attach to the triceps muscle area of the patient's upper arm, sliding seat 25-2 is used to attach to the elbow joint, and sliding seat 25-3 is used to attach to the brachioradialis muscle area of the patient's forearm. By attaching the patient's triceps muscle, elbow joint, and brachioradialis muscle of the forearm to the corresponding sliding seats 25-1, 25-2, and 25-3, the patient's arm is fixed, which can improve the stability and safety of the dialysis process. During hemodialysis, the patient's arm needs to maintain a fixed position for a long time to ensure that the dialysis needle or catheter can be accurately inserted into the blood vessel and remain stable. By using corresponding sliding seats 251, 252, and 253 to attach to the triceps surae of the patient's upper arm, elbow joint, and brachioradialis muscle of the forearm, the patient's arm can be effectively fixed, preventing it from moving or shaking during dialysis. This ensures that the dialysate can smoothly enter and exit the patient's blood vessels, improving dialysis efficiency. Fixing the arm also reduces the risk of complications such as vascular damage, bleeding, or infection caused by patient movement, ensuring patient safety. It allows the patient to maintain a relatively comfortable posture during dialysis, reducing arm fatigue and discomfort.
[0033] A bellows 4 is provided between adjacent sliding seats 25. The bellows 4 can extend and retract along its length. A second track is provided on the arm placement component along its length. An air passage is provided on the second track. A sliding block is provided on the sliding seat 25. The sliding block is slidably fitted on the second track. The sliding seat 25 has an air passage 2 that flows with the first air passage and the air source. The bellows 4 is used to seal the non-contacting part between the first air passage and the second air passage of the adjacent sliding seat 25 within the placement cavity. An air passage 3 is provided on the arm placement component. The air inlet of the air passage 3 flows with the first air passage, and the air outlet is provided with an opening and closing device. The opening and closing device can close the air outlet of the air passage 3 or separate it from the air outlet to open the air outlet.
[0034] Specifically, a second track is provided on the inner wall of the arm placement component. The second track has two functions: one is to allow the sliding block to slide, and the other is to serve as an air passage. The air source connected to the arm placement component flows through the pipe to the air passage. The air passage is formed by the second track on the arm placement component. The air source generates suction through the hose, air passage, and air passage. The second air passage is set on the sliding block and the sliding seat 25 to form an integral air passage. This arrangement allows multiple sliding seats 25 to be placed inside the arm placement component without affecting the sliding.
[0035] To ensure a more secure fixation of the arm placement device and prevent patients from moving it during hemodialysis, a connecting frame 5 is installed on the bed body 1. The connecting frame 5 can slide along the length of the bed body 1 in a lockable manner. A telescopic rod 6 is installed on the connecting frame 5, and the movable part of the telescopic rod 6 is connected to the arm placement device to adjust the height of the arm placement device.
[0036] An air bladder 24 is provided on the inner wall of the arm placement device. The air bladder 24 can be inflated to fit snugly against the patient's arm or deflated to separate from the patient's arm. The arm placement device includes an upper placement part 21 and a lower placement part 22 that is rotatably disposed on the upper placement part 21. The upper placement part 21 and the lower placement part 22 are fastened together to form a placement cavity. The inner walls of both the upper placement part 21 and the lower placement part 22 are provided with air bladders 24. The air bladders 24 can relieve the contact pressure between the arm placement device and the patient's arm, allowing the patient to maintain a relatively comfortable posture during dialysis and reducing arm fatigue and discomfort.
[0037] The wrist joint fixation component 3 includes a mounting frame 31, a first fixation member 32 for fixing the palmar muscles of the patient's hand, and a second fixation member 33 for fixing the area near the pisiform bone of the patient's hand, forming a fixation part. The first fixation member 32 and the second fixation member 33 are slidably fitted onto the mounting frame 31 in a lockable manner. Specifically, the first fixation member 32 includes a screw and a suction cup, and the second fixation member 33 includes a screw and a flexible air bag. The screws are threaded to the mounting frame 31. By rotating the corresponding screws, the positions of the suction cup and the flexible air bag are adjusted, thereby better fixing the palmar muscles and the area near the pisiform bone of the patient's hand, ensuring the stability of the patient's hand during hemodialysis, preventing needle dislodgement or pain due to movement, and minimizing pressure on the patient's hand, thus improving comfort.
[0038] This article uses specific examples to illustrate the principles and implementation methods of the present invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of the present invention. The above descriptions are only preferred embodiments of the present invention. It should be noted that due to the limitations of textual expression, and the objective existence of infinite specific structures, those skilled in the art can make several improvements, modifications, or changes without departing from the principles of the present invention, and can also combine the above technical features in an appropriate manner; these improvements, modifications, changes, or combinations, or the direct application of the inventive concept and technical solution to other situations without modification, should all be considered within the scope of protection of the present invention.
