Abstract
Description
Technical Field
[0001] The utility model relates to the field of medical instruments, in particular to an invisible test tube rack anti-backflow structure. Background Art
[0002] During the egg retrieval operation, an egg retrieval needle is used to collect eggs directly from the ovaries through the vagina. The egg retrieval needle is connected to a test tube, which is placed on a constant temperature test tube rack. The other end of the egg retrieval needle is connected to an aspirator. If too much suction is performed and the follicular fluid level is too high, the follicular fluid will reflux into the drainage bottle. Since eggs are sensitive to light, the egg retrieval operation needs to be performed in a dark room environment, and the test tube capacity is limited. Nurses need to concentrate and change test tubes frequently, otherwise reflux is likely to occur. At the same time, nurses must also observe the patient's vital signs and hand over follicular fluid with embryo laboratory personnel. There is still a risk of follicular fluid reflux. Reflux can cause egg loss, and follicular fluid reflux requires disinfection of the entire set of equipment, increasing instrument loss and labor and disinfection costs. At present, the commonly used constant temperature chamber tube racks on the market are made of transparent materials, so nurses can directly observe the height of the test tube pages. However, this structure of the test tube is not conducive to the heat preservation of the test tube rack, which can easily lead to unstable temperature and damage to the eggs. The other is a closed invisible test tube rack. This test tube rack has good heat preservation effect and constant temperature, but it cannot be observed. When the liquid level exceeds the constant temperature chamber tube rack, it is often close to the critical point, and the risk of reflux is high. The liquid level height monitoring of the invisible test tube rack can be achieved by using a contact infrared sensor, such as the Chinese utility model patent with application number CN202021465024.1 and the name of the biological reagent liquid level detection device. However, this method still has the risk of causing damage to the eggs and introducing contamination. Utility Model Content
[0003] The technical problem to be solved by the utility model is to provide an invisible test tube rack anti-reflux structure which can avoid egg damage.
[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: an invisible test tube rack anti-backflow structure, including a test tube rack, a test tube jack is provided on the top of the test tube rack, a constant temperature chamber is provided inside the test tube rack, a pressure sensor is provided in the constant temperature chamber, the pressure sensor is located vertically below the test tube jack, a main board and a relay alarm are provided on the test tube rack, and the main board is respectively connected to the pressure sensor and the relay alarm.
[0005] Furthermore, the test tube rack includes a frame and a spliced shell covered on the frame.
[0006] Furthermore, the spliced shell is a light-shielding shell.
[0007] Furthermore, a temperature control module is provided in the constant temperature chamber, and the main board is connected to the temperature control module.
[0008] Furthermore, at least two test tube insertion holes are arranged at intervals on the top of the test tube rack, and at least two pressure sensors are arranged in one-to-one correspondence with the at least two test tube insertion holes.
[0009] The beneficial effects of the utility model are: an invisible test tube rack anti-backflow structure. The eggs are sensitive to light and temperature, so a constant temperature chamber is provided inside the test tube rack to ensure constant temperature. A pressure sensor is used to support the test tube inserted into the test tube jack, and the liquid level height data is converted into pressure data of the pressure sensor at the bottom of the test tube to avoid damage to the egg.

When the main board collects the data and the follicular fluid height approaches the critical value, the control alarm is sounded, and the monitoring alarm will not damage the egg at the same time. The invisible test tube rack anti-reflux structure provided by the utility model can monitor the pressure data at the bottom of the test tube in real time, monitor the pressure changes caused by the liquid level of the follicular fluid and issue a warning in time through a relay alarm, so as to avoid the damage to the egg by the traditional infrared liquid level detection device and the pollution problem that may be caused by the contact liquid level detection device, avoid the unclear field of vision caused by dark room operation, and remind the operating room nurse to replace the test tube in time to prevent the loss of the egg due to the reflux of the liquid level. It can allow the operating room nurse to pay more attention to the patient, pay attention to the patient's vital signs and emotional changes in time, and improve the patient's safety and service quality.
