Problems solved by technology

[0003] The midwifery instrument in the prior art includes a handle and an airbag connected to the handle. The airbag enters the puerpera's body to help the puerpera give birth, which can promote the eugenics of the puerpera, reduce maternal and child complications, and reduce the probability of cesarean section. Advantages such as any drug, but it also has the problem of not being able to accurately control the diameter of the bionic air bag, which in turn cannot ensure that the pain of the pregnant woman is minimized very effectively

no. 1 example

[0036] see figure 1 , the first embodiment of the present invention provides a midwifery instrument, which includes an air pump, a one-way valve, an air tank, an airflow valve, an airbag handle, an imitation airbag, an exhaust valve, a pressure sensor, a three-way valve, a control The device and the pipeline connecting the components in the midwifery instrument. The air pump communicates with the air tank through a pipeline, and inflates the air tank. The air tank is connected to the airbag handle through an inflation pipeline, the airflow valve is installed on the inflation pipeline, and the air tank is inflated to the imitation airbag through the airflow valve and the airbag handle in sequence. The exhaust valve is installed between the air bag handle and the air flow valve. The pressure sensor is installed between the air tank and the air bag handle, and is used to measure the gas pressure in the air tank and the bionic air bag before and after each inflation of the bioni...

no. 2 example

[0046] see figure 2 , the second embodiment of the present invention provides a midwifery instrument, the structure of the midwifery instrument is basically the same as that of the midwifery instrument provided by the first embodiment, the difference is that the exhaust valve is installed on the air between the tank and the airflow valve. Specifically, an exhaust pipeline is provided on the inflation pipeline between the air flow valve and the air tank, and the exhaust valve is installed on the exhaust pipeline.

[0047] The method for controlling the diameter of the above-mentioned bionic air bag provided in this embodiment is basically the same as the method for controlling the diameter of the bionic air bag in the midwifery instrument provided in the first embodiment, except that:

[0048] Step 3, the controller continues to close the airflow valve for a period of time, the air tank stops inflating the bionic airbag, and the bionic airbag maintains its predetermined diame...

Abstract

The invention provides a delivery instrument. The delivery instrument comprises a controller, an air tank, an airflow valve, an air bag handle and a bionic air bag arranged on the air bag handle; the air tank, the airflow valve and the air bag handle are orderly connected with each other; the controller is connected with the airflow valve; a pressure sensor, which is capable of measuring the air pressures of the air tank and the bionic air bag, respectively, is mounted between the air tank and the air bag handle; the pressure sensor is connected with the controller and transmits the air pressure of the air tank and the air pressures of the bionic air bag before and after each inflation to the controller; the controller converts the air pressure measured each time into a bionic air bag diameter signal and determines whether or not to control the airflow valve to enable the air tank to inflate the bionic air bag with air according to the bionic air bag diameter signals obtained by conversion each time. As a result, the delivery instrument is capable of accurately controlling the diameter of the bionic air bag. The invention also provides a bionic air bag diameter control method.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a structure of a midwifery instrument and a method for controlling the diameter of an imitation air bag in the midwifery instrument. Background technique [0002] With the development of society and the advancement of science and technology, eugenics has become an important measure to improve the quality of the population, and it has also received increasing attention from the whole society. The most common method of childbirth in humans is natural vaginal birth. [0003] The midwifery instrument in the prior art includes a handle and an airbag connected to the handle. The airbag enters the puerpera's body to help the puerpera give birth, which can promote the eugenics of the puerpera, reduce maternal and child complications, and reduce the probability of cesarean section. However, it still has the problem of not being able to accurately control the diameter of the bionic air bag,...
