Or table drive working principle


Generally, there are 3 kinds drive for or table:
1. Hydraulic transmission means that the oil is injected into the tubing from the tank through an oil pump, solenoid valve controls the opening and closing of the oil circuit, using hydraulic pressure to push the piston in the hydraulic cylinder to achieve various positions of the operating table.

2. Mechanical transmission means sending signals to the motor through the control circuit, the motor drives the transmission components such as the turbine, the worm, the gear, and the rack, thereby realizing various actions of the operating table.

3. The pneumatic part is mainly driven by a self-locking gas spring. The self-locking gas spring has a needle valve at the end of the piston rod. When the needle valve is opened, the self-locking gas spring can be freely adjusted to achieve various positions of the operating table, when the needle valve is released, the self-locking type gas spring can be locked in position at the moment, and the self-locking force is large, and the support can be achieved.

Surgical teaching system solution

图片
Why do we recommend the surgical teaching system solution? The first reason is the driving force for the development of the medical imaging system market. National policy support: The state encourages the development of digital operating rooms and has launched research on related topics. The development of medical information needs; with the advancement of medical industry information construction, the demand for video teaching, telemedicine, and information archiving has increased. Product performance improvement: The development of high-definition camera, network transmission and other technologies has accelerated the application of camera products in the medical industry. Medical accidents occur frequently and doctor-patient disputes increase. The frequent occurrence of medical malpractice prompted the hospital to archive video in order to avoid disputes. The second reason is that the surgical teaching system is the key to the advancement of the hospital. Conduct li

Inspect before using the medical pendant

图片
Medical pendant is an indispensable gas supply medical equipment for modern operating room. Its main function is to supply oxygen, absorption, compression and other medical gases in the operating room. It is recognized by healthcare professionals because of its superior performance. However, we should do the inspection before using it, so that we can be prepared. Pre-inspection work of medical pendant: 1.        Check if all the parts of the PICU pendant are intact. Sometimes, when transporting or storing, due to the accumulation of products, the structure will be deformed. Be sure to check before installation, do not ignore the problem of deformation and damage, otherwise it will easily collapse or break due to improper force when used. 2.        Check that each bracket is complete and ensure that no items are missing, including instrument platform, drawers, infusion stand, sundries, etc. Although the lack of these parts does not have a great impact on safety, but when using

What is the difference between cold light source and thermal light source?

图片
  The cold light source we often say does not actually refer to those light sources that do not generate heat during the light-emitting process, but refers to the light-emitting method that is not like the traditional light source that converts heat energy into light energy. In fact, it refers to a cold light source that uses chemical energy and electrical energy to excite the light source, and has the characteristics of variable flicker. The thermal light source we are talking about is a light source excited by thermal energy. During the light-emitting process, most of its energy needs to be converted into thermal energy, and then converted from thermal energy into light energy. Therefore, the thermal energy loss is relatively high, and the luminous efficiency is not cold light source. high. However, there are also advantages. Hot light sources can be directly connected to the circuit, and the maximum brightness can be achieved at the moment of power-on, but cold light sources cannot.
