Problems solved by technology

[0003] 1. The pressure is unstable, the suction is not enough, the follicular fluid is not sucked clean, and the egg retrieval rate is low; or the pressure is too high, the suction is strong, and the suction speed is too fast, resulting in egg damage;
[0004] 2. When a cyst in the ovary is punctured during the egg retrieval process, due to the viscous part of the cyst, it is not easy to suck out the cyst fluid, and it is necessary for the auxiliary personnel to constantly adjust the appropriate pressure on the side. Frequent manual adjustment of the pressure is inefficient.
[0005] 3. It cannot automatically sense the air leakage of the egg collection system and the leaking parts, and it needs to be manually detected before the egg collection
[0006] There is no corresponding automation equipment that can solve this technical problem in the prior art

Embodiment 1

[0034] Such as figure 1 , 6 Among them, an intelligent negative pressure suction control system, which includes a handle base 2 fixed on the handle 15, the handle base 2 is provided with a switching value control device 100, and the switching value control device is electrically connected to the acquisition device 3;

[0035] The acquisition device 3 is electrically connected with the main control device 5 in a wireless or wired manner;

[0036] The main control device 5 is electrically connected with the vacuum device 16 in a wireless or wired manner;

[0037] To control the suction negative pressure of the vacuum device 16 through the control device. With this structure, when in use, the operator can adjust the magnitude of the negative pressure through the switching value control device 100, and this adjustment is linear and smooth. Especially through wireless or wired connection, the weight of the handle 17 of the whole egg retrieval system will not be greatly increased...

Embodiment 2

[0046] On the basis of Example 1, the corresponding negative pressure can be adjusted by adjusting the vacuum device 16, but due to the existence of air in the pipeline and in the test tube, there is a certain hysteresis in this adjustment. The preferred solution is as follows: figure 2 Among them, a negative pressure control valve 9 is also provided on the negative pressure pipe 11, and the main control device 5 is electrically connected with the negative pressure control valve 9 in a wireless or wired manner. With this structure, through the adjustment of the flow cross section, the adjustment of the negative pressure can be quickly fed back, and it is also convenient to match with the change of the negative pressure.

[0047] The preferred solution is as Figure 4 , 5 Among them, the structure of the negative pressure control valve 9 is that the valve body 91 is provided with a staggered exhaust pipe 92 and an intake pipe 95, and a slit is provided between the ends of the...

Embodiment 3

[0051] On the basis of Examples 1 and 2, the preferred scheme is as figure 1 , 2 Among them, the wireless connection method adopts one of radio frequency, infrared, bluetooth, WiFi or zigbee wireless modules; radio frequency, infrared, bluetooth, WiFi or zigbee wireless modules are all commercially available products, taking radio frequency as an example, preferably adopting The LT8920 solution is small in size. The zigbee wireless module preferably adopts the W5100 series chip of Beijing Bokong Automation Technology Co., Ltd., and the wifi module preferably adopts it. The solution of adopting the zigbee wireless module can facilitate the networking of the collection device 3 , the main control device 5 and the main control device 5 . The main control device 5 is preferably a chip of 51 series, AT series, STM32F series, capable of inputting sensor signals and wireless connection signals, and outputting control pulse signals. The main control device 5 is powered by an indepe...

Abstract

The invention provides an intelligent vacuum aspiration controlling system, and relates to the field of medical equipment. The intelligent vacuum aspiration controlling system includes a handle base which is fixed on a handle, wherein a switching value controlling device which is arranged on the handle base is electrically connected to a collection device, the collection device is electrically connected with a main control device in a wireless or wired mode, and the main control device is electrically connected with a vacuuming device in a wireless or wired mode, so that negative-pressure suction of the vacuuming device is controlled through the main control device. Through the switching value controlling device which is arranged on the handle, the negative pressure of the vacuuming devicecan be adjusted quickly, accurately and conveniently, so that the negative pressure of the vacuuming device is consistent with the actual need of a surgery.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to an intelligent negative pressure suction control system. Background technique [0002] In the process of in vitro fertilization and embryo transfer technology, when the follicles mature, the eggs in the ovary need to be sucked into the test tube outside the body through the egg retrieval needle and negative pressure aspirator, and then follow-up operations such as insemination. The pressure of the negative pressure suction device currently used clinically needs to be manually set in advance. During the egg retrieval process, the appropriate pressure cannot be adjusted according to the pressure in the follicle. The existing problems are: [0003] 1. The pressure is unstable, the suction is not enough, the follicular fluid is not sucked clean, and the egg retrieval rate is low; or the pressure is too high, the suction is strong, and the suction speed is too fast, resulting in egg d...
