Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, in particular to a convenient-to-operate hemodialysis device. Background Art

[0002] Hemodialysis is one of the renal replacement therapies for patients with acute and chronic renal failure. It involves draining blood from the body to the outside of the body and passing it through a dialyzer composed of numerous hollow fibers. An electrolyte solution (dialysate) with similar concentrations between the blood and the body is exchanged through diffusion convection inside and outside the hollow fibers, removing metabolic waste from the body, maintaining electrolyte and acid-base balance, and removing excess water from the body. The entire process is called hemodialysis.

[0003] However, when the hemodialysis device is in use, many hoses (for disinfectant, acid, dialysate, drainage, and fluid supply) are connected to its surface. After these hoses are plugged into the hemodialysis device, the hoses are distributed in a disordered manner. In addition, the hemodialysis device is transported or transferred (on casters) to the designated location for use. When used near the bed, patients, visiting family members, and nurses may collide with the hemodialysis device when walking.

[0004] In view of this, a convenient-to-operate hemodialysis device is proposed. Utility Model Content

[0005] The purpose of this section is to summarize some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and in the abstract and title of the utility model to avoid obscuring the purpose of this section, the abstract and the title of the utility model, and such simplifications or omissions shall not be used to limit the scope of the present invention.

[0006] In view of the following technical problems in the existing technology: when the hemodialysis device is in use, many hoses (for disinfectant, acid, dialysate, drainage and fluid supply) will be connected to its surface. After these hoses are plugged into the hemodialysis device, the hoses will be distributed disorderly, and the hemodialysis device is transported to the designated location for use by carrying or transferring (castors). When used near the bed, patients, visiting family members and nurses will all pose a risk of collision with the hemodialysis device when walking.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions: a convenient-to-operate hemodialysis device, comprising a device body, a display and a socket;

[0008] The surface of the device body is rotatably connected to an acrylic plate, which can protect the socket. The surface of the acrylic plate is provided with a first docking hole and a second docking hole, and the first docking hole and the second docking hole are staggered.

[0009] A storage cavity is provided on the side of the equipment body, and a limiting mechanism is provided in the storage cavity. The limiting mechanism mainly includes a supporting frame, an outer shell frame, a limiting frame 1 and a limiting frame 2. One end of the supporting frame is hinged in the storage cavity, the outer side of the outer shell frame is fixedly connected to the other end of the supporting frame, the limiting frame 1 is fixedly connected to the outer side of the outer shell frame, and the limiting frame 2 is in a rotational connection with the outer shell frame.

[0010] As an optimal technical solution for a convenient-to-operate hemodialysis device, the socket is provided on the surface of the device body, the display is mounted on the top of the device body, and a support frame is provided on the side of the device body close to the display.

[0011] As an optimal technical solution for a convenient-to-operate hemodialysis device, the docking hole 1 and the docking hole 2 both include a long hole and a round hole. The round hole is a connecting channel between the open end of the acrylic plate and the long hole. The diameter of the long hole is larger than the spacing between the round holes, ensuring that the hose can be limited when plugged into the designated position, further preventing the hose from being scattered.

[0012] As an optimal technical solution for a convenient-to-operate hemodialysis device, a holder is provided below the docking hole 1 and the docking hole 2. The holder is "L"-shaped and can guide the hose extending from the long hole to ensure that multiple hoses can be clearly arranged.

[0013] As an optimal technical solution for a convenient-to-operate hemodialysis device, a rotating shaft is rotatably connected inside the outer shell frame, a threaded hole is provided on the side surface of the outer shell frame, a spline groove is provided on the side of the rotating shaft facing the threaded hole, a spline shaft is inserted into the spline groove, and under the action of the spline groove and the spline shaft, some positional movement caused by the threaded transmission can be overcome.

[0014] As an optimal technical solution for a convenient-to-operate hemodialysis device, a threaded rod is provided at one end of the spline shaft, and the threaded rod and the threaded hole are in a threaded transmission relationship. Under the action of the threaded transmission, the limit frame 2 has a self-locking effect after being rotated to a certain angle.

[0015] As an optimal technical solution for a convenient-to-operate hemodialysis device, a linkage sleeve is provided on the outer side of the rotating shaft, wherein the linkage sleeve moves synchronously with the rotating shaft, and the outer side of the linkage sleeve is fixedly connected to one end of the limiting frame 2, and the limiting frame 2 and the limiting frame 1 have limiting grooves on their opposite inner edges, and a telescopic adjustment frame and an adjustment plate are provided in the limiting groove, and the adjustment frame and the adjustment plate are provided with springs on the side facing the limiting groove, so that they can be used with bed rods of different sizes.

[0016] As an optimal technical solution for a convenient-to-operate hemodialysis device, the middle section of the adjustment frame is an inclined section, which can guide and adjust bed rods of different sizes when they enter the limiting grooves.

[0017] Beneficial effects of the utility model:

[0018] The hemodialysis device is inserted through the circular hole through the hose, and the position of the long hole is limited, so that the joint positions of each hose can be separated. After the acrylic plate is closed, some hoses are inserted into the clamping seat. At this time, the positions of the hoses on each socket can be clearly distributed, which can prevent the hoses from being scattered, making the operation of the entire hose more convenient when docking with the device body, thereby improving the overall efficiency.

[0019] The hemodialysis device is first connected to the bed rod through the limit groove on the limit frame 1, and the threaded rod is rotated so that the limit groove on the limit frame 2 is connected to the bed rod. At this time, the two limit grooves wrap the bed rod, and the device body is now stably connected to the bed, thereby preventing the device body from shaking or tipping over due to collision.

[0020] When the acrylic plate of the hemodialysis device is closed, the joint between the device body and the hose can also be prevented from misoperation.

[0021] Other features and advantages of the present invention will be described in the following description, and in part will become apparent from the description, or understood by practicing the present invention. The purpose and other advantages of the present invention can be achieved and obtained through the structures particularly pointed out in the description and the drawings.
