Application of sensors in dialysis machines

Sensors play an important role in dialysis machines, and the sensor's platform technology benefits designers.

In order to provide the patient with the same fluid temperature and body temperature to ensure the safety of the patient, temperature management solutions and pressure sensors are also used in the dialysis machine. Rather than looking for multiple temperature technologies and sensors from multiple suppliers, purchasing heater assemblies and pressure sensors from a single accessory manufacturer not only streamlines the manufacturing process and supply chain, but also simplifies assembly and reduces design time. Give developers more time and energy to research other systems. Platformized sensing provides a complete assembly that meets regulatory requirements and enables the system to meet relevant quality standards.

The heater assembly heats the blood and dialysate to the body temperature before it is reintroduced into the patient. In this process, the heating controller can precisely control the temperature of the dialysate; the circuit board-mounted pressure sensor can measure the flow rate of the fluid exiting and entering the patient, and obtain the dialysate and venous pressure without disturbing the fluid flow. reading.

Erosion adds the complexity and cost of protection.

In order to implement the use of a temperature sensor in combination with a temperature adjustment device, the heater assembly needs to be designed with various heating techniques and materials suitable for the design requirements of different dialysis machines. The design of these dialysis machines often requires consideration of different types of heating techniques due to the different size and temperature ranges of the heater assemblies.

The heater assembly should have a variety of sizes, power, mounting options, and temperature monitoring and temperature control capabilities. Because, in the same dialysis machine application, different heater assembly configurations (flat, transparent composite and high temperature) and manufacturing materials (silicon, polyimide film, polyester indium tin oxide, and other dielectric materials) are available. Produce different application options.

Accurate measurement of dialysate and venous pressure is critical for patient safety during dialysis treatment. Pressure sensors require accurate detection of fluid and blood flow pressures to ensure that the pressure is maintained within the applicable range and that overpressure or underpressure conditions are avoided. Because either the overpressure or the low pressure will cause the blood vessel to break or bubbles in the pipeline, respectively.

The best way to get more accurate and faster response time is to place the sensing element as close as possible to the flow of liquid. This requires the use of pressure sensors with liquid media compatibility to reduce the complexity and cost associated with sensor protection design.

In addition, pressure sensors should provide a variety of mounting options to suit different applications. By providing cable assembly options, the sensor platform can be installed in remote locations or products with limited interior space. As a result, designers can place sensors accurately where they can be measured accurately.

Raschel Machine

Raschel machine is a type of knitting machine used to produce fishing net and sport net, a type of lace fabric that is commonly used in clothing and home textiles. The machine is named after its inventor, Karl Mayer Raschel, and is characterized by its ability to produce complex patterns and designs in a wide range of materials, including cotton, silk, nylon, and polyester.

Raschel machine works by using a series of latch needles to knit the yarn into a patterned fabric. The needles are arranged in a warp knitting configuration, with each needle working independently to create a loop in the yarn. The machine can be programmed to create a wide variety of patterns and designs, including floral motifs, geometric shapes, and intricate lace patterns.

Raschel lace is known for its durability and strength, making it a popular choice for use in clothing and home textiles. It is often used in lingerie, swimwear, and bridal wear, as well as in curtains, tablecloths, and other decorative textiles.
