Definitions
- the present invention relates to a device for gas insufflation and collection of effluents from body cavities of an individual, preferably a device for insufflation of gas rectally for distention of the intestines during the performance of an image scan of said intestines.
- the present invention refers to a device that allows gas, for example air or carbon dioxide, to be introduced into the intestines of a patient so that they are distended, thus allowing diagnostic imaging methods to be practiced.
- gas for example air or carbon dioxide
- a device for reducing these problems comprises: a gas insufflator apparatus, a first conduit for the supply of gas provided by the insufflator apparatus into a body cavity of the individual; barriers inserted in the first duct to prevent the passage of effluents from the individual into the interior of! insufflator apparatus, a collection tank for said effluents, a member insertable in a cavity of the individual, attachable to the first conduit and provided with an expandable annular element for the perimeter closure of the cavity of the individual; and means for swelling of the expandable annular element once the insertable member is inserted into the individual's body cavity.
- the effluents that occur during the exploration pass through the first conduit and are collected in the reservoir.
- This device poses several problems, the main ones being that the first conduit carries out the insufflation of the gas as for the collection of effluents, which contributes to greater contamination of the insufflator device.
- the insufflator device must withstand the excess pressure that may occur during the diagnostic process, which reverts to the fact that it must absorb gases that come from the cavity, becoming contaminated even if the barriers are effective in the presence of liquids and solids.
- the document of the PCT application WO2005105198 A1 by "Manually operated insufflator", of the signature EZ-EM INC describes a manual device to distend the abdominal cavity of a subject and that includes in a construction a gas tank to insufflate , an insertable member for insertion into an abdominal cavity and a manually operated pump to introduce the gas from the reservoir through an intermediate conduit for communication with the insertable member.
- This device is designed to perform learning practices for diagnostic tests. Therefore its construction is simple to obtain a reduced cost and does not present certain safety measures used in other devices, or these are simpler.
- to regulate the gas pressure in the cavity it comprises a valve in the intermediate duct, just before the manual pump, for intuitive operation, which allows the overpressure output. This valve does not prevent effluents and contaminating gases from leaving it right where the doctor operates the pump, reducing the aseptic management.
- a device comprising an insert member in said cavity with a balloon for its fixation and plugging of the entrance to the cavity.
- This insertable member is connected by means of valves or valves with an irrigation liquid reservoir, drainage means to a drain collection tank once the irrigation has been carried out.
- This device allows the entry of the irrigation liquid and the exit of the liquid once the irrigation is carried out through ducts parallel within the insertable member, avoiding contamination of the irrigating liquid, said liquid being maintained within the cavity for the desired time.
- This device is not intended to perform colonoscopies by air or gas insufflation, since it does not have adequate means for the constant and simultaneous handling of the introduction of the pressurized gas and the collection of effluents, necessary throughout the diagnosis. .
- the device for the insufflation of gas and collection of effluents from body cavities of an individual, object of this invention presents some technical peculiarities intended to improve patient comfort and ensure the cleaning and sanitation of the gas insufflator apparatus.
- the device comprises: a gas insufflator apparatus, a first conduit for the supply of gas provided by the insufflator apparatus into a body cavity of the individual; barriers inserted in the first conduit to prevent the passage of effluents from the individual into the insufflator, a collection tank for said effluents, a member insertable in a cavity of the individual, attachable to the first conduit and provided with an annular element expandable for the perimeter closure of the individual's cavity; and means for swelling of the expandable element once the insertable member is inserted into the individual's body cavity.
- the first conduit has a branch to which a second gas evacuation conduit is provided, provided with a safety valve for the automatic release of gas to the outside when the gas pressure contained in the first conduit exceeds a default value
- the insertable member comprises at its rear end a first mouth for the coupling of the first conduit with a first inner passage provided with an outlet located in an area close to the anterior end of the insertable member, a second mouth for coupling of an effluent evacuation conduit with a second inner passage provided with an outlet located in an area close to the anterior end of the insert member and a third mouth for the connection of the inflation means of the expandable annular element with a third inner passage provided with an outlet located inside the expandable annular element.
- the insufflator is practically blowing gas constantly and said gas flow to the patient prevents liquids and effluents into the rectum and the colon from entering the first duct.
- This device allows that when the gas enters through a passage and the effluents are collected through a different passage, a better elimination of said effluents occurs. This facilitates the work of the radiologist who performs the diagnostic procedure by not distorting the image obtained by said effluents, properly collected.
- the first conduit presents in the section between the connection branch of the second conduit and the end connected to the insufflator apparatus, a second branch to which a probe for the introduction of gas into a patient's cavity through the mouth is connected or the nose
- the length of the effluent evacuation duct, connected to the second mouth of the insert member is sufficient to collect the effluents produced.
- the effluent evacuation conduit, connected to the second mouth of the insertable member is connected at its rear end to an effluent collection vessel when these are abundant.
- the second gas evacuation duct comprises scented barriers that prevent the gases that go outside to return from being annoyed by their bad smell.
- the gas insufflator apparatus comprises means for heating the gas to be supplied.
- These gas heating means comprise a thermostat that regulates the heating of the gas at a temperature around 37.5 degrees Celsius, so that the gas introduced into the individual's cavities is at a temperature according to the body temperature, instead of the low temperature that decompressed gas usually comes from a bottle, for example. This improves patient comfort and is subjected to a less tense situation.
- At least one of the barriers arranged in the first conduit comprises antiviral or antibacterial materials, so that the gas evacuated to the outside is cleaner. Also to! less one of the barriers comprises a hydrophobic filter that prevents said gas evacuated to the outside from presenting some type of moisture or contaminant associated with the water, in addition to increasing the safety and cleanliness of the insufflator apparatus.
- the device comprises clamping, clamping or blocking means arranged in the first conduit before the barriers and in the evacuation conduit, so that when the diagnosis has been made, the spillage of the effluents upon removal and Discard media that are single use.
