Description
Technical field
The utility model relates to a kind of medical instruments, especially disclose a kind of colonic manometry conduit, are used for gastrointestinal tract dynamia
Colonic manometry in detection.
Background technique
Stomach and intestine dynamics detection technique passes through development in more than 20 years, and high-resolution pressure measuring system is widely used in stomach food at present
The detection such as pipe reflux, constipation, colonic activity.High resolution bathymetric pressure divides two ways: 1, hydraulic gastroenteritic power inspection is perfused in liquid water
It surveys, 2, solid-state survey pressure probe gastroenteritic power detection.Be widely used in clinical use at present is that Ningbo Mai Da company produces
Hydraulic gastroenteritic power detection system is perfused for pressure catheter, liquid water and biofeedback training system carries out surveying pressure and biofeedback is controlled
It treats.
Pressure measuring system, the conduit in terms of mainly having for oesophagus, manometry in rectum at present, temporarily not for tying is perfused in liquid water
Intestines survey the conduit of pressure.
If Chinese patent ZL 2,004 2 005790.2 discloses filling type enteron aisle pressure catheter, conduit is enclosed with air bag,
Need to be inflated to it when measurement makes its expansion stimulate rectum intestinal wall neural, then by pressure tap measure sigmoid colon, rectum,
The wave amplitude of each section of intestinal wall nerve conduction of anal canal internal sphincter is detected.
And pressure measuring catheter for digestive system disclosed in Chinese patent ZL 2,005 2 012293.1, including tube body, it is fixed on pipe
The capsule of body one end and the connecting tube and pipe fitting composition for being connected to the other end, design at least 5 in the tube body
A chamber, the biggish chamber in center is filling cavity, and surrounding small chamber is pressure measuring cavity, one end of filling cavity and each pressure measuring cavity equal communicating pipe
The other end of connector, filling cavity is connected to rubber bag tank target seeker, and the other end of each pressure measuring cavity is with setting in tube body close to target seeker
Side opening connection at position, each side opening can be located on the same radial section of tube body, can also be arranged in catheter body in the shape of a spiral
On tube wall., can be relatively difficult by narrow enteric cavity but since the pressure catheter front end is air bag, it is difficult to measure narrow section intestines
The pressure of chamber.So clinically, the pressure catheter length is shorter, it is only used for the perfusion to digestive system, gradient surveys pressure, complies with
Sexuality is known and vector surveys the operation such as pressure, can also be achieved diagnosis digestive system dyskinesia and detection muscular movement power,
But the survey pressure of colon is not suitable for it.
What it is currently used for colonic manometry is the i.e. high score using solid pressure measuring system in such a way that constipation patient colon surveys pressure
It distinguishes that colonic pressure measures, is to survey pressure in lateral colon descendens using 36 Sensor solid-states and pop one's head in, 1 centimetre of range sensor.Pass through
This solid pressure measuring system detects colon pressure, can accurately reflect the pressure change of colon, but a solid-state pressure catheter
About 100,000 yuan, somewhat expensive is unfavorable for medical applications and popularization.
Summary of the invention
The purpose of this utility model is to solve the defect of the prior art, designs a kind of colonic manometry conduit, classics can be used
8 channel water injection pressures measure colonic pressure, and manipulate simple, using effect is good, and measurement result is accurate.
The utility model is realized in this way: a kind of colonic manometry conduit, the catheter body including being equipped with central through hole, institute
The catheter body one end connection connecting tube and pipe fitting stated, the other end are equipped with 8 channel water and pressure tap, the 8 channel water are perfused
8 outlets of perfusion pressure tap are perfused pressure measuring system with external water by connecting tube and pipe fitting respectively and are connected to, it is characterised in that:
The central through hole is guidance seal wire through-hole, and pincers road junction of the colonic manometry conduit through colonoscopy, edge guidance seal wire is forward
It is advanced into the survey pressure section for being located at obstruction proximal end, is equipped in the catheter body between 8 outlets of 8 channel water perfusion pressure tap
One radiopaque label, the catheter body length are 160~220cm.
The catheter body uses polyvinyl chloride pipe, and the central through hole diameter of outer diameter 3.3mm, the catheter body are
1.0~1.25mm.8 outlets of 8 channel water perfusion pressure tap are separated by 1.5cm, and pressure tap road is perfused in corresponding 8 channel water, each
It is 0.6mm that pressure tap road diameter, which is perfused, in water, is arranged on the tube wall of catheter body in the shape of a spiral.
The the 6th to the 8th water that one end that the radiopaque label is located at self-conductance tube body insertion enteron aisle is risen, which is perfused, to be surveyed
It presses between mouth.
The beneficial effects of the utility model are: the utility model uses silica gel system compared with existing solid-state pressure measuring system
At, about 1500 yuan of the cost of a conduit, cooperate 8 classical channel water injection pressure measurement methods, effectively reduce use at
This.The utility model conduit can be passed through from the pincers road junction of electronics colonoscopy, per anum approach, be pushed ahead along guidance seal wire, Ke Yifang
Just the narrow section for passing through enteric cavity can be used for colon, jejunum survey pressure, tie most probably in intestinal obstruction patient particular up to ileocecus
Intestines survey pressure, understand influence of the obstruction of colon colonic pressure variation to body.The utility model not only manipulates, using simplicity, but also
It is accurate to survey pressure precision.
