Description
Technical field
The invention belongs to gastroenterology the field of medical instrument technology, and in particular to one kind is suitable for gastrorrhagia situation and supervises in real time
The fixable type gastrorrhagia monitoring capsule endoscope and gastrorrhagia real-time monitoring system of survey.
Background technique
Acute hemorrhage of upper gastrointestinal tract means bleeding caused by the alimentary canal illness of Qu Shi ligament or more, is clinical common urgency
It examines, case fatality rate is high.Wherein the most common position of upper gastrointestinal bleeding is stomach, accounts for 60% or more of entire upper gastrointestinal bleeding, out
Blood lesion is most commonly seen with peptic ulcer, gastric cancer, stress ulcer, portal hypertension gastopathy.Acute hemorrhage of upper gastrointestinal tract is suffered from
Person's common clinical manifestation is the peripheral circulatory failures such as spitting blood, melena symptom and dizziness, pale complexion, increased heart rate, blood pressure reduction
Sign.
For the diagnosis of the gastrorrhagia cause of disease, gastroscope is the most key inspection, can detect upper gastrointestinal mucosa situation in time,
The treatment such as herbal sprinkling injection, coagulation treatment heat and hemostatic clamp can be carried out to lesion in time simultaneously.But there is quite a few patient
It will appear the risk of bleeding again after receiving Hemostasis through endoscopy treatment.Gastrocopy simultaneously is an invasive invasive operation,
Patient has very strong sense of discomfort when checking, therefore in the clear cause of disease, moves back mirror after completing Endoscopic Treatment, can not real-time monitoring
Stomach inner disease foci situation.Clinician often passes through hemoglobin in the clinical manifestations such as the spitting blood of patient, hematochezia and blood routine examination
Concentration, red blood cell count(RBC) judge the amount of bleeding and bleeding of patient.
Capsule endoscope (capsule endoscopy) full name is " intelligent capsule digestive tract endoscope system ", is that one kind is made into
The endoscope of capsule shape includes built-in camera shooting and signal transmitting apparatus, is allowed to move in alimentary canal by peristalsis of the digest tract
And image is shot, and doctor utilizes external image recorder and image workstation, understand the entire alimentary canal situation of subject, from
And diagnosis is made to its state of an illness.Capsule endoscope have small in size, hurtless measure, it is disposable, without advantages such as cross-infections.Now in
The capsule endoscope of clinical application is divided into oesophagus capsule endoscope, small intestine capsule endoscope, magnetic control capsule stomach according to the difference of check point
Mirror, colon capsule endoscope etc..According to the different set of capsule endoscope function, gastrointestinal pressure, pH value, power can be monitored by deriving
The capsule of the different roles such as capsule.But there is presently no it is a be capable of fixing in stomach specific position stomach inner disease foci is carried out it is real-time
The capsule endoscope of monitoring.
For the patient of acute gastrorrhagia in the case where carrying out positive Endoscopic Treatment, Bleeding rate is still higher again in 3 days,
Once bleeding occurs again, death risk can be increased rapidly.But rely solely on the clinical manifestation of patient, hemoglobin, indicators
Judge that amount of bleeding often has certain retardance, rescue cannot be implemented in first time, it is even more impossible to find out in patient's stomach
Specific bleeding and healing of focus situation.Still lack at present it is a kind of can in real-time monitoring stomach situation equipment and technology, so as to
Stomach internal haemorrhage situation is reminded and alarmed to clinician in time.
Summary of the invention
The present invention is to carry out to solve above-mentioned technical problem, provides one kind and is capable of fixing the specific position pair in stomach
The fixable type gastrorrhagia that gastrorrhagia position carries out real-time monitoring monitors capsule endoscope, and the stomach comprising the capsule endoscope
Bleeding real-time monitoring system.In order to realize that purpose, the technical solution adopted in the present invention are as follows:
<structure one>
Fixable type gastrorrhagia monitoring capsule endoscope provided by the invention has following technical characteristic: including capsule shells
Body has nontransparent capsule housing and transparent capsule shell two parts；Endoscope fixed part, including be fixed at nontransparent

The action and effect of invention
Fixable type gastrorrhagia monitoring capsule endoscope and gastrorrhagia real-time monitoring system provided by the invention have as follows
Technical effect:
Firstly, since endoscope fixed part is provided in fixable type gastrorrhagia monitoring capsule endoscope, by therein
Gastric tissue is drawn into body of stomach tissue accommodating chamber by Miniature negative pressure pump, is then fixed by fine needle arrangement, thus by capsule
Endoscope is fixed in gastral cavity specific position, is persistently taken pictures to lesion, achievees the purpose that obtain lesion bleeding in real time.
Patient implantation capsule endoscope, connect data conversion instrument and monitor after, can normal activity, to capsule battery
When will exhaust, endoscope side microprocessor controls micromotor and reversely rotates, and fine needle is detached from from body of stomach tissue, realizes glue
Capsule falls off from stomach wall automatically, and excludes from anus.Entire monitoring process is easy to operate, patient's no pain, clinician and trouble
Person can observe stomach inner disease foci bleeding in real time, and the treatment and processing for bleeding patients first time again provide help.
Secondly, the fixable type gastrorrhagia in the present invention monitors in capsule endoscope and is also provided with pH value detection electrode and pH
It is worth sensor, the image in addition to obtaining bleeding part, moreover it is possible to detection data is obtained by pH value, realization carries out situation in stomach
More fully monitor.
Third contains connecting sleeve in gastrorrhagia real-time monitoring system of the invention, which is gastroscope
Connecting pin, the other end are capsule endoscope connecting pin, and capsule endoscope is connected to gastroscope camera end (side by the connecting sleeve
Visor) it can be operated.Transparent connecting sleeve allows capsule endoscope to be installed in the case where gastroscope camera lens is observed in real time, glue
Capsule endoscope lens open shooting oesophagus, the real-time pictures in stomach simultaneously, and the two is same to the observation of stomach internal haemorrhage situation and lesion
Step, therefore capsule fixation procedure can be realized and is accurately positioned to lesion.
4th, monitor is divided into monitor and mobile monitors by bed, and it is sleeping to be suitable for the big need of bleeding risk for monitor by bed
The patient of bed, big display screen facilitate doctor and patient to check patient's stomach internal haemorrhage situation in time, and mobile monitors are made with mobile phone etc.
For carrier, situation in the stomach of observation monitoring in time when facilitating patient activity.
