Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to a quantifiable intestinal inflation device. Background Art

[0002] Intestinal inflation is a common auxiliary treatment method in gastrointestinal surgery. It can help doctors expand the intestines to facilitate better surgical operations.

[0003] Intestinal inflation can be used to assist in the treatment of certain intestinal problems, such as intussusception. In the treatment of intussusception, air is injected into the intestinal cavity, and the pressure of the air is used to reposition the intussusception. In addition, intestinal inflation can also be used to assist in the diagnosis of certain intestinal problems, such as intestinal stenosis or intestinal obstruction. By inflating the intestine, the intestinal morphology and structure can be more clearly displayed in X-rays or CT scans, which helps doctors diagnose the problem more accurately. It should be noted that intestinal inflation needs to be performed under the guidance of a doctor, and care should be taken to control the pressure and amount of inflation to avoid damage to the intestine.

[0004] At present, a common gastrointestinal inflation device requires the pipe to be removed before air is introduced, and then the pipe is connected before inflation. The process of pipe connection and removal is prone to cause pollution, which in turn is likely to affect the health of the patient, and has certain defects. Utility Model Content

[0024] Figure 1 The utility model is a schematic diagram of the overall structure of the quantifiable intestinal inflation device. DETAILED DESCRIPTION

[0025] The following will be described in more detail with reference to the schematic diagram of the present invention, wherein the preferred embodiment of the present invention is shown, and it should be understood that the present invention described herein can be modified by a person skilled in the art, while still achieving the advantageous effects of the present invention. Therefore, the following description should be understood as being widely known to a person skilled in the art, and not as a limitation to the present invention.

[0026] The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the accompanying drawings are in very simplified form and in non-precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0027] like Figure 1 As shown, the embodiment of the utility model provides a quantifiable intestinal inflation device, including an inflation cylinder 1, a piston rod 2 and an air intake pipe 3.

[0028] Specifically, the inflatable cylinder 1 has an output end, and the output end is provided with a control valve 4 , and the inflatable cylinder 1 also has an inflating chamber 5 .

[0029] The piston rod 2 is slidably disposed inside the inflation cylinder 1 , and the piston rod 2 compresses the gas in the inflation chamber 5 by sliding, and inflates the gas through the output end.

[0030] The air intake pipe 3 is arranged on the outer side wall of the inflation cylinder 1 , and the air intake pipe 3 is communicated with the inflation chamber 5 , and the air intake pipe 3 is used to provide an air intake channel to the inflation chamber 5 .

[0031] In this embodiment, the output end is connected to the patient's stomach and intestines through a pipeline. When the patient's stomach and intestines need to be inflated, the air intake pipeline 3 is closed, and the piston rod 2 is pressed to fill the gas in the inflation chamber 5 into the patient's stomach and intestines. When the gas in the inflation chamber 5 is completely filled, the output end is closed, the air intake pipeline 3 is opened, and the piston rod 2 is pulled out from the inflation chamber 5 to the outside. At this time, the external gas enters the inflation chamber 5 through the air intake pipeline 3. At this time, the piston rod 2 can be pressed to fill the gas into the patient's stomach and intestines again. In this cycle, an appropriate amount of gas can be filled into the patient's stomach and intestines.

[0032] In a specific embodiment, the outer wall of the inflation tube 1 is provided with scale marks 6. When using the inflation device, medical staff can intuitively record the amount of inflation each time, and thus can accurately and quantitatively inflate the patient's stomach.

[0033] In order to facilitate the air intake operation of the inflation chamber 5, a one-way valve 7 is provided between the air intake pipe and the inflation cylinder 1. External gas can only enter the inflation chamber 5, and the gas in the inflation chamber 5 cannot be discharged through the air intake pipe.

[0034] In addition, in order to allow external gas to smoothly enter the inflation chamber 5, the air inlet pipe 3 is arranged at one end of the inflation cylinder 1 close to the output end. When the piston rod 2 is pulled outward, the external gas can be sucked into the inflation chamber 5.

[0035] Furthermore, the output end includes a sealing end cover 8 and an output sleeve 9.

[0036] Specifically, the sealing end cover 8 is fixedly arranged at the end of the inflation cylinder 1 .

[0037] The output sleeve 9 is disposed on the sealing end cover 8 , and the output sleeve 9 is communicated with the inflation chamber 5 .

[0038] In this embodiment, the sealing end cover 8, the output sleeve 9 and the inflator 1 are integrally formed, the control valve 4 is mounted on the output sleeve 9, and the control valve 4 is a straight-through valve. When the inflatable chamber 5 needs to be inflated, the control valve 4 is closed and the piston rod 2 is pulled, and the external gas passes through the inlet pipe 3 and enters the inflatable chamber 5.

[0039] Furthermore, the piston rod 2 includes a driving piston 10 , a push rod 11 and a pushing plate 12 .

[0040] Specifically, the driving piston 10 is fixedly disposed at the end of the push rod 11 , and the driving piston 10 is in close contact with the inner wall of the inflation chamber 5 and in sliding contact.

[0041] The pushing plate 12 is fixedly disposed at the end of the push rod 11 , and the pushing plate 12 faces away from the driving piston 10 .

[0042] In this embodiment, the outer diameter of the pushing plate 12 is greater than the inner diameter of the inflation cavity 5 .

[0043] In this embodiment, when the patient's stomach needs to be inflated, the push disk 12 is pressed, so that the driving piston 10 squeezes the internal space of the inflation chamber 5, thereby filling the gas inside the inflation chamber 5 into the patient's stomach. When the inflation chamber 5 needs to be inflated, the push disk 12 is pulled outward.

[0044] Compared with the prior art, the utility model has at least the following beneficial effects:

[0045] The utility model takes in air through the air intake pipe, and can continuously inflate the patient's stomach and intestines without removing the inflation cylinder and the patient's gastrointestinal tract, thereby reducing infection during the removal and connection of the gastrointestinal tract and improving the efficiency of inflation. It has the characteristics of simple structure and convenient operation.

[0046] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
