Definitions

• the present invention relates to a probe for facilitating the execution, via endoscopy, of a haemostasis (sclerosis or binding of varices) in case of bleeding of the oesophagus varices.
• a preceding European Patent Application 0 874 657 of the same Applicant discloses a device which can be managed by one person other than the operator using the endoscope.
• Such device is formed of a tubular member of flexible material which connects at its distal end two bladders that are inflated to isolate the operating field from the gastric cavity and the proximal portion of the oesophagus . According to a peculiar feature, the length of the tubular member between the two bladders is perforated.
• tubular member The inside of such tubular member is suitably divided into three ducts, one aspiration duct with greater diameter being connected directly to the perforated length and two smaller ducts communicating with such bladders independent of each other.
• the two ducts separate from the main duct at the proximal area so as to form corresponding tubular ducts smaller than the main duct, each such duct being connected to inflating or deflating means independent of each other.
• Such a construction allows the operation to be executed under more favourable circumstances such as : easier cleaning of the operating area from the considerable quantity of blood through the suction channel which the device is provided with; blocking of the reflux of the blood from the stomach to the oesophagus; prevention of the reflux of the blood to the upper respiratory tract and reduction of ab ingestis pneumonias; more effective suction of the blood in the gastric cavity; and keeping of a desired pressure in the operating area.
• a device conceived as above has shown some problems limiting its actual use.
• a first significant problem depends on the fact that, after the device is put into the mouth of the patient and the distal bladder has been inflated, the operator using the endoscope has to put such instrument into the operating area by passing it sideways on the still deflated proximal bladder.
• the latter bladder is in turn inflated to define an isolated operating room where the endoscope has to carry out a sclerosis, it is easy to occur that the endoscope is pushed against the wall of the oesophagus, thus causing the patient to feel pain.
• the endoscope probe is passed inside the proximal bladder.
• such bladder is provided with a suitable tubular duct passing therethrough completely apart from and independent of the main duct .
• a second problem which has been arising consists in that it is not always possible to locate the field where the operation takes place via endoscope.
• the invention provides that the last length of the device just before the distal bladder is black coloured by about 5 cm or coloured by a colour which is in contrast with the remaining portion of transparent material .
• Fig. 1 is a general view of the device,-
• Fig. 2 shows in particular the length of the device between the two bladders with the entrance of the tunnel for the endoscope into the proximal bladder and the black-coloured length preceding the distal bladder,-
• Fig. 3 is a section view of the proximal bladder showing the off-center position of the tunnel for the endoscope and the presence of a diaphragm valve.
• the device or the probe of the invention includes a composite, flexible tubular member consisting of a duct A-H with circular section from which two tubular ducts FG and FI both with circular section and reduced diameter branch off at point F
• Two bladders BC and DE are provided in the length between point A and point F.
• the length of the duct between the two bladders BC and DE is perforated.
• the whole device is better described in European Patent Application No. 0 874 657 of the same Applicant which is integral part of the present disclosure and incorporated therein by reference.
• bladder DE of natural rubber or latex has a pipe or duct 6 allowing the endoscope to pass and running parallel to pipe or duct AH.
• the endoscope is no longer squeezed against the wall of the oesephagus and the inflated bladder does not interfere with the activity of the operator using the endoscope.
• FIG. 3 shows the relative position of the duct for the endoscope and the supply pipe AH. It is evident that the position can be varied in a suitable way and it should be appreciated that the two ducts are fully independent of and not communicating with each other.
• the same figure shows a diaphragm valve 8 at the input of the duct 6 which prevents blood and cleaning liquids from rising from the operating room to above the proximal bladder.
• a similar valve can also be provided at the output of duct 6 from the proximal bladder.
• the last length of pipe AH before the distal bladder is of a contrasting colour, preferably black, in order to allow the operator to locate quickly and skilfully the point where the sclerosis or any other endoscopic intervention has to be carried out.
