Description
Technical field
This utility model relates to the medical imaging diagnostic device, relates in particular to a kind of pulmonary ventilation imaging device.
Background technology
Lung perfusion imaging is a kind of conventional method that is used to diagnose pulmonary embolisms disease and assessment pulmonary ventilation function, and the pulmonary ventilation imaging device is the common equipment of this diagnostic method.Present existing pulmonary ventilation imaging device is that atomization cylinder and filtering cloth jar are placed in the shielding of plumbous system, to reduce the physical impairment of radiopharmaceutical to the operator.During use, high pressure oxygen or 10Pa medical air are injected in the atomization cylinder, make medicinal liquid in the atomization cylinder reach atomizing particle about 1-30um and become aerosol, the patient will be difficult to articulate and cover in oral area, thereby sucking aerosol by breather develops pulmonary, gas of breathing out and the aerosol that does not suck are being transported in the filtering cloth jar by breather, and gas is after filtering discharged by air vent, has reduced the radioprotective to operator.But the atomization cylinder of this pulmonary ventilation imaging device communicates with filtering cloth jar and the single tube of breather for directly being connected with filtering cloth jar, atomization cylinder, the testee sucks by breather and the gas of exhalation just mixes, the gas of Hu Chuing is sucked by the testee once more like this, prolong respiratory time and increased depositional phenomenon, and when patient's Halfway Stopping sucks, aerosol with radioprotective can be leaked in the air by the suction side, pollutes video picture and pops one's head in and the healthy of people around had a negative impact.In addition, because the medicine injection port is opened the sidewall at atomization cylinder, lead screen also needs one opening is set so that the medicine syringe passes in the relevant position except that the oxygen air inlet of the exhaust port at top and bottom, increased the medicine radioprotective, and when injectable drug, medicinal liquid is adhesion on tube wall easily also.
The utility model content
For overcoming the shortcomings and deficiencies that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of pulmonary ventilation imaging device, and the gas that uses this image reproducer to make the testee suck exhalation separates, and has accelerated testee's respiratory time, improves the video picture quality.
For achieving the above object, pulmonary ventilation imaging device of the present utility model by atomization cylinder, filtering cloth jar, be built in defecator in the filtering cloth jar, breather, and lead screen constitute, described filtering cloth jar 11 is divided into medicine filtering cloth jar 14 and gas filtration cylinder 13 by filtering sealing coat 4; One atomizing sealing coat 5 is set between gas filtration cylinder 13 and the atomization cylinder 12; Described breather constitutes by the breathing of U type is two-tube, and suction nozzle 6 communicates with atomization cylinder 12, is provided with the valve 8 of unidirectional unlatching to the right in suction nozzle 6; Exhaust tube 7 communicates with gas filtration cylinder 13, is provided with the valve 9 of unidirectional unlatching to the left in exhaust tube 7.
Further, described medicine syringe 3 passes and extends to the atomization cylinder 12 by the air vent 1 of lead screen open top from filtering cloth jar 12; Described suction nozzle 6 is provided with closed opening device 15; Described closed opening device 15 is a manually-operated gate.
Compared with prior art, this utility model since adopt sealing coat with the gas filtration cylinder with the medicine filtering cloth jar is separated and the U type is breathed two-tube and in breathing is two-tube unidirectional opening device is set, the gas that sucks and breathe out is separated, increased the drug level in the atomization cylinder, accelerated respiratory time, thereby improved the video picture quality, also reduced simultaneously the testee and be inhaled into the adverse effect that causes depositional phenomenon once more owing to the gas of breathing out has, and when the testee ends to suck suddenly halfway, the unidirectional opening device of suction side can seal suction inlet immediately, thereby the aerosol of avoiding having radioprotective is leaked in the air.In addition, one closed opening device is set, can makes operator end the suction of atomization gas at any time, improved the safety that equipment uses in the suction side; Further the medicine injection port is changed into by the atomization cylinder sidewall and directly is deep in the atomization cylinder by the air vent of medicine syringe by filtering cloth jar, lead screen has only the oxygen inlet of the air vent at top and bottom and the medicine interface need not be set specially like this, reduced radioprotective, and medicinal liquid is injected directly into the atomization cylinder from the medicine syringe, reduced the adhesion of medicine on tube wall.

The specific embodiment
Below in conjunction with the drawings and the specific embodiments this utility model is described further.
The structure of the Reference numeral representative in each accompanying drawing is as follows: 1, air vent 2, oxygen inlet 3, medicine syringe 4, filter sealing coat 5, atomizing sealing coat 6, suction nozzle 7, exhaust tube 8, right one-way Open valve 9, the unidirectional Open valve 10 in left side, lead screen 11, filtering cloth jar 12, atomization cylinder 13, gas filtration cylinder 14, medicine filtering cloth jar 15, closed opening device 16, be difficult to articulate 17, defecator.
The pulmonary ventilation imaging device of prior art as shown in Figure 1, filtering cloth jar 11 and atomization cylinder 12 10 clads of shielding by lead system are to prevent radioprotective.Lead screen 10 except that the oxygen inlet of the air vent at top and bottom, sidewall also have one with the corresponding medicine injection port of atomization cylinder, medicine syringe 3 communicates with atomization cylinder by this opening.Filtering cloth jar 11 communicates with atomization cylinder 12 and by being threaded to one, the breather atomization cylinder links to each other, filtering cloth jar 11, atomization cylinder 12 communicate, in filtering cloth jar 11, be provided with the defecator 17 of filter paper as medicine and gas, the gas that the testee sucks exhalation mixes in atomization cylinder 12 and filtering cloth jar 11, and the gas of exhalation is inhaled into once more; Medicine injects by the syringe on atomization cylinder 12 sidewalls 3, because medicine syringe 3 is to stretch out from atomization cylinder 12 and lead screen 10 levels, and when injection, medicine adhesion on tube wall easily.
