Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, but rather should be construed as broadly as the present invention is capable of modification in various respects, all without departing from the spirit and scope of the present invention.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the utility model herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1 to 3, an inflation infusion device for an infusion bag of a uterus expanding machine according to an embodiment of the present invention includes an inflator 1, an air pipe 2, and an inflation bag 3.

The inflator 1 is used to supply gas. One end of the gas pipe 2 is connected with the inflator pump 1. One end of the inflatable bag 3 is a closed end, the other end of the inflatable bag is an open end, the inflatable bag 3 comprises an inner layer 31 and an outer layer 32, an inflatable cavity 33 is formed between the inner layer 31 and the outer layer 32, the inflatable cavity 33 is connected with the other end of the air conveying pipe 2, and an accommodating cavity 34 communicated with the open end is formed inside the inner layer 31. In the working state, the infusion bag is placed in the containing cavity 34, and along with the air pump 1 pumping the air into the air inflation cavity 33 through the air pipe 2, the containing cavity 34 gradually expands to extrude the infusion bag so as to provide the pressure required by infusion of the infusion bag.

As is well known to those skilled in the art, when the uterus expander is used for transfusion, a transfusion tube is firstly connected into a transfusion bag, and then liquid in the transfusion bag is extruded out through extrusion and is supplemented into a uterine cavity through the uterus expander.

When the device works, the infusion bag is firstly placed in the accommodating cavity 34, and the infusion tube of the uterus expanding machine is to be connected with the infusion. Then the inflation pump 1 inflates the inflation bag 3 gradually, the inflation cavity 33 expands to enable the accommodating cavity 34 to be gradually reduced, so that the infusion bag is extruded, and after the infusion bag is extruded, liquid in the infusion bag is gradually input into the infusion tube and enters the uterine cavity through the uterine dilator. Because the inflation pump 1, the gas pipe 2 and the inflation bag 3 provide the extrusion force required by infusion of the infusion bag, manual extrusion operation is replaced, and the infusion bag has the advantages of convenient operation and labor saving.

The device also comprises an air pressure detection mechanism 4 and a controller 5, wherein the air pressure detection mechanism 4 is arranged on the inflation cavity 33, and the controller 5 is respectively electrically connected with the air pressure detection mechanism 4 and the inflator pump 1. The air pressure detecting mechanism 4 can transmit the detected pressure value of the inflation cavity 33 to the controller 5, and the controller 5 can control the action of the inflator 1 according to a preset command. The air pressure detecting means 4 may be an air pressure sensor which is hermetically mounted on the outer layer 32 of the air-filled cavity 33.

Specifically, the air pressure detection mechanism 4 is arranged on the inflation cavity 33, and when the inflation cavity 33 is inflated and expanded, the air pressure detection mechanism 4 can detect the pressure value of the inflation cavity 33 in real time and control the action of the inflator pump 1 accordingly, so that the relative automation of infusion is realized. When the infusion bag is gradually reduced, the accommodating cavity 34 is synchronously reduced, and at the moment, the inner layer 31 of the inflatable bag 3 expands inwards to reduce the air pressure in the inflatable cavity 33. After detecting the data, the air pressure detecting mechanism 4 transmits the data to the controller 5, and the controller 5 controls the inflation action of the inflator 1. In this embodiment, a set air pressure range value of the operation of the inflator 1 may be set, and when it is detected that the air pressure value of the inflation cavity 33 is smaller than the low value of the set air pressure range value, the controller 5 controls the inflator 1 to inflate the inflation cavity 33. When the air pressure value of the inflation cavity 33 is detected to be larger than or equal to the high value of the set air pressure range value, the controller 5 controls the inflator 1 to stop inflating the inflation cavity 33.

Of course, the air pressure detecting mechanism 4 may also be a barometer, and the inflator 1 may also be a pedal-type inflator 1, the air inflation cavity 33 is inflated by the pedal-type inflator 1, and the air pressure in the air inflation cavity 33 is observed by the barometer.

In this device, a binding string 38 is provided in the circumferential direction of the open end of the air bag 3. Specifically, a plurality of binding strings 38 are provided in the circumferential direction of the open end. After the bag is placed in the receiving cavity 34, the open end can be sealed by the tying rope 38 to prevent the bag from leaking. This structure can improve the practicality of this device.

In the device, an inflation inlet 35 is arranged on the inflation cavity 33, and an inflation valve 36 is arranged at the inflation inlet 35. The inflation valve 36 may be a single check valve or a multiple inflation and deflation valve. When the inflation valve 36 is not inflated, the inflation port 35 can be automatically sealed, and gas leakage is avoided. Meanwhile, when the air needs to be deflated, the air in the inflation cavity 33 can be discharged for reuse or convenient storage.

In this device, a hanging ring 37 is provided on the outer surface of the outer layer 32. The device can be hung on the support frame through the hanging ring 37 so as to carry out transfusion.

In the present apparatus, the outer layer 32 and/or the inner layer 31 is a composite film of PE (polyethylene resin) and PA (polyamide resin). Of course, the material of the outer layer 32 and the inner layer 31 may be an airtight bladder.

In the device, the connection part of the closed end is connected in an integrated way, and the inner layer 31 and the outer layer 32 can be supported by a piece of integral material, so that the manufacturing cost can be reduced.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
