Description
Technical field
The invention belongs to technical field of medical equipment, and in particular to a kind of crossover connection for injecting medical treatment device.
Background technology
Secretory otitis media is using hydrotympanum and Hearing as the middle ear inflammatory disease of main feature.The cause of disease is mainly
Obstruction of eustachian tube, tympanum endocrine cannot be drained to pharyngeal, formation hydrotympanum.Hydrotympanum is mostly omission timber, diffusate
With the mixture of juice.It is the key that treatment secretory otitis media to remove hydrotympanum.Hydrotympanum is sucked out in tympanotomy
It is the most common therapy of tympanitis, it is simple and practicable.Wherein, when treating secretory otitis media, after conventional tapping
Need second of inserting needle injection, form two holes sometimes, when injection drug from another pin hole reflux to eardrum outside；In addition, secondary
Puncture also can making patients puncture pain.
CN105496644A discloses a kind of auripuncture, Injection in Tympanic Cavity medical treatment device, including：First sting device,
Second sting device and suction unit, the first sting device include puncture needle and first connector, the second sting device packet
Injection needle and second connector are included, suction unit includes negative pressure mechanism and third connector；When by puncture needle and injection needle
It, can be by the third connector of suction unit and the when needing to aspirate intratympanic hydrops after being inserted into the tympanum of patient
Second connector of two sting devices is spirally connected；When needing to Injection in Tympanic Cavity liquid, the third of suction unit can be connected
Head is screwed out from the second connector, and the 4th connector of injection device is screwed into the second connector.
The medical treatment device has the following advantages：Since second puncture needle is set in inside first puncture needle, when the first puncture
When the eardrum of pin puncture patient, the second puncture needle that first puncture needle can drive it internal also punctures the eardrum of patient, and first
Both puncture needle and second puncture needle only form on the eardrum of patient there are one puncturing hole, when needing to aspirate intratympanic hydrops
Or when needing to Injection in Tympanic Cavity liquid, it is only necessary to select corresponding connector (third connector or the 4th connector) and second
Connector connects, and forms two holes on eardrum without secondary puncture and causes outside liquid reflux to eardrum, secondary will not wear
It pierces and increases the pain punctured to patient.
But the medical treatment device also has the following deficiencies place：When suction hydrops and injection drug two kinds of functional status it
Between when converting, need after disassembling a sting device, can just load onto another sting device, operation is relatively complicated；Separately
When outside due to conversion operation, the syringe needle of injection needle and puncture needle also extends through eardrum and is located in tympanum, and so cumbersome function turns
Operation is changed, the shake because of hand is easy, syringe needle is caused accidentally to prick other positions in ear.
