Description
Technical field
The utility model relates to a kind of medical instruments, are especially used for the auxiliary device of fiberoptic bronchoscopy.
Background technique
Pulmonary tuberculosis merges bronchogenic tuberculosis patient and row branchofiberoscope etc. is usually needed to check, further to define diagnosis
Or treatment, but often this kind of patient is often active tuberculosis, sputum bacteria experiment in part is positive, has very strong infectiousness, domestic
Many hospitals or bronchuscopy room threaten medical worker and ambient enviroment with stronger infection without complete safeguard
Effect.
Such patient be expert at fiberoptic bronchoscopy when usually induce acutely cough, can lead to a large amount of germs of lung and pass through
Air borne enters in inspection chamber, and conventional mask is weaker to tulase protective capacities, this medical matters poor for Some Constitution
Personnel's infection risk with higher, the country have more document report.Li Jing's rose is to one, Shenyang general hospital's investigation result
Surface, medical worker's PPD positive rate are 60%, hence it is evident that higher than infection rate 48.5% (P < 0.001=, the ratio of non-medical staff
Value is 8.29 than (OR).The TB infection rate investigation that Henan Province TB prophylactico-therapeutic institution staff carries out, finds whole body TB prophylactico-therapeutic institution
The PPD positive rate of staff is 57.3%, and the positive rate of medical worker is 62.8%.According to the summary that joshi etc. writes, the whole world
In middle and low income country, medical worker's Mycobacterium tuberculosis average rate is 54% (33%-79%).Cook etc. is to U.S.'s knob
Data carries out retrospective analysis between about 1994-2001, and the PPD positive rate investigation result of medical staff is 51.6%-60.0%.
Especially active tuberculosis patient is huge to society and medical team harm.
Many Supervisory Office's disinfection and isolation systems are simultaneously not perfect at present, only in ventilation reduction infection risk, operation take
The mode to wear masks prevents and treats tubercle bacillus affection.But tulase survival ability is extremely strong, especially piecemeal activity bronchogenic tuberculosis, tool
There is extremely strong infectiousness, ambient enviroment is entered by air, so that medical worker's sense still with higher in the environment
Contaminate risk.
Summary of the invention
The purpose of the utility model is to provide a kind of anti-infection Fibro-bronchoscopy test auxiliary device, patient puts on the auxiliary device
In mask carry out fiberoptic bronchoscopy when, tulase outlet can be effectively prevent, to avoid tulase to inspection chamber ring
The infection of border and medical worker.
Anti- infection Fibro-bronchoscopy test auxiliary device described in the utility model, including mask offer inlet valve on mask
And outlet valve, Bronchofiberscope jack is also provided on mask, inlet valve is breather cheek valve, and outlet valve is unidirectional air outlet valve；Also
Including closed disinfect box, it is provided with partition in disinfect box by disinfect box and is separated into the first disinfection room and the second disinfection room, first
Disinfection room is connect by pipeline with the outlet valve, ultraviolet light source is arranged inside, the second disinfection room is provided with sterilizing
Liquid is provided with negative port on the disinfect box where the second disinfection room；U-tube is provided in disinfect box, U-tube is interspersed in partition
On, arrival end is located in the first disinfection room, and outlet end is located in the second disinfection room, and the outlet end is sterilized thimerosal and floods
Not yet.
Pressure reducing valve is installed on the disinfect box where the second disinfection room.
Rubber ring is fixed at the Bronchofiberscope jack of mask, centre bore and the Bronchofiberscope jack of rubber ring overlap, rubber
Rubber stopper is connected in rubber ring, which can close the center hole plug of rubber ring.
When carrying out fiberoptic bronchoscopy to patient, mask is worn over patient facial region, and will be where the second disinfection room
The negative port being arranged on disinfect box is connect with negative pressure source, and branchofiberoscope is inserted by the rubber ring centre bore on mask suffers from
In person's body.Due to the effect of breather cheek valve and unidirectional air outlet valve, oxygen and air can only be entered in mask by inlet valve, and
The gas that carries disease germs of patient's exhalation then can only enter pipeline from outlet valve, enter the first disinfection room by the pipeline, the gas that carries disease germs exists
Ultraviolet light antivirus is carried out in first disinfection room.Since the second disinfection room is negative pressure, under the action of negative pressure, after ultraviolet light is killed virus
Gas enters in the second indoor disinfection solution of disinfection through U-tube is killed virus again, later, the gas after killing virus again
Into the negative pressure space on the second disinfection room top, it is discharged from negative port.
The effect of U-tube is to import the first indoor gas of disinfection in the second disinfection room, while preventing the second disinfection room
Interior disinfection solution flows into the first disinfection room.
The pressure reducing valve installed on disinfect box where second disinfection room, effect are the indoor negative pressure of the second disinfection of control
Value prevents from leading to the false triggering of outlet valve because the second indoor negative pressure of disinfection is excessive.
Fixed rubber ring at the Bronchofiberscope jack of mask is reliable in order to enable Bronchofiberscope jack and Bronchofiberscope to carry out
Sealing cooperation.The center-hole diameter of rubber ring should be slightly less than the caliber of Bronchofiberscope, and Bronchofiberscope can be with rubber ring when being inserted into
Centre bore remains interference fit, prevents the exchange of the mask inner air and outer air when carrying out Fibro-bronchoscopy test.Bronchofiberscope is not being inserted
When, the center hole plug can be closed with the rubber stopper connected on rubber ring, when not inserting Bronchofiberscope, can also be prevented inside and outside mask
The exchange of air.
The utility model, can be by patient when carrying out fiberoptic bronchoscopy to patient due to having this kind of structure
The gas that carries disease germs of exhalation is guided in disinfect box, second level sterilization processing is carried out in disinfect box, by the tulase in the gas that carries disease germs
It is discharged after killing, makes to check indoor air that there is no tulases, to effectively prevent tulase to checking indoor environment
And the infection of medical worker.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of anti-infection Fibro-bronchoscopy test auxiliary device described in the utility model.
Fig. 2 is the cross-sectional view on the auxiliary device mask at Bronchofiberscope jack.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
Shown in Figure 1, the anti-infection Fibro-bronchoscopy test auxiliary device, including mask 6 offers inlet valve on mask 6
