Description

Stethoscope hammer for neurology

Technical Field

The invention relates to the technical field of medical instruments, in particular to an auscultation hammer for neurology.

Background

Neurology is an independent secondary subject and does not belong to the concept of internal medicine, the nervous system consists of brain, spinal cord and peripheral nerves, and the neurology is clinical medicine for researching nervous system diseases and skeletal muscle diseases and is mainly researched by means of internal medicine. The diseases include spinal cord and cerebrovascular diseases, central nervous system infection, demyelinating diseases, dyskinesia diseases, epilepsy, headache, degenerative diseases, nervous system hereditary diseases, etc. The main examination means of neurology comprise head and neck MRI, CT, ECT, PETCT, electroencephalogram, TCD transcranial Doppler ultrasound electromyography, evoked potential, blood rheology examination and the like.

The auscultation hammer is frequently used in the examination of neurology, the hammer head of the auscultation hammer used at present has two types, namely a barbed roller and a flexible contact, and the selection is carried out according to the condition of a patient in the diagnosis process. When the stethoscope with the thorn roller is used, a doctor presses the thorn roller on the skin of a patient and then takes the thorn roller to roll along the same trend. While the auscultatory hammer with flexible contacts is mostly used to tap the patient's joints to observe the nerve response. When the patient who needs to carry out above two kinds of detections in the face, the doctor then need carry two kinds of auscultation hammers, not only carries inconvenience, and need change different auscultation hammers as required when checking for the patient, troublesome poeration.

Disclosure of Invention

The invention aims to provide an auscultation hammer for neurology, and aims to solve the problems that in the prior art, the auscultation hammer is inconvenient to carry and troublesome to operate.

In order to achieve the purpose, the invention provides the following technical scheme:

auscultation hammer for department of neurology, the electric iron comprises a handle, the inside chamber of aerifing that is provided with of handle, aerify the intracavity and be provided with fixed establishment, it is provided with the piston to aerify the intracavity slip, the piston rod of piston is located outside the one end of handle, it has the outlet duct to aerify chamber one end intercommunication, the handle other end is provided with flexible hammer, be provided with a plurality of pinholes on the flexible hammer, be provided with a plurality of felting needles that can pass the pinhole on the gasbag, intercommunication between gasbag and the outlet duct has the intake pipe, the intake pipe rotates with the center department of flexible hammer to be connected, the symmetry is provided with the through-hole in the intake pipe, through-hole department is provided with elastic cloth, it has the horizontal pole to articulate.

The principle of the invention is as follows:

the flexible hammer is used for knocking the joint of a patient, and the handle is convenient for a doctor to hold for examination. When the flexible hammer is used, the fixing column on the cross rod is inserted into the sleeve on the flexible hammer to fix the flexible hammer and prevent the flexible hammer from rotating. When the roller with the puncture needles is needed to be used, the gas in the inflation cavity is pushed into the air bag by pushing the piston, the volume of the air bag is increased, and the puncture needles on the air bag penetrate through the needle holes on the flexible hammer to extend out of the flexible hammer to form the roller with the puncture needles. Then extract the fixed column from the sleeve to in the through-hole that the horizontal pole made the fixed column on it inserted the intake pipe, the elastic cloth of through-hole department can take place deformation in order to seal the intake pipe, prevents that gas from spilling over. At this point, the flexible hammer is pushed to roll on the skin of the patient for examination. The fixing mechanism is used for fixing the position of the piston and preventing the piston from moving to cause gas to overflow.

The invention has the beneficial effects that:

1. the flexible hammer is rotationally connected with the air inlet pipe, and the fixed column is pulled out of the sleeve to release the flexible hammer, so that the flexible hammer can rotate; the gas in the inflation cavity is pushed into the air bag by pushing the piston, so that the volume of the air bag is increased, the pricker on the air bag penetrates through the needle hole on the flexible hammer and extends out of the flexible hammer to form the roller with the pricker, and the requirement that a patient needs to check by using the roller with the pricker can be met.

2. The flexible hammer is secured by inserting a securing post into a sleeve on the flexible hammer so that the flexible hammer can be used to strike a joint of a patient for examination.

3. The invention combines the flexible hammer and the roller with the puncture needle, combines the two auscultation hammers together, does not need to carry a plurality of tools when a doctor checks, is convenient to carry, can complete the conversion between the flexible hammer and the roller with the puncture needle by pushing the piston, and has simple operation.

The disinfection chamber can be opened to the slide damper, slides flexible hammer to the disinfection intracavity, and the disinfection of flexible hammer can be accomplished to the disinfection intracavity towards filling sterile gas to switch on the sterilizer to kill the bacterium on the flexible hammer.

Furthermore, the piston rod is rotatably connected with the piston, the fixing mechanism comprises a clamping groove formed in the side wall of the inflation cavity, and a bolt capable of being clamped into the clamping groove is arranged on the piston rod of the piston. When the piston needs to be fixed, the piston is rotated to enable the plug pin on the piston to be clamped into the clamping groove, and then the piston can be fixed.

Furthermore, the adjusting mechanism comprises a gear arranged in the disinfection cavity, the air inlet pipe is provided with a driving gear capable of being meshed with the gear, the handle is provided with a rotating wheel, and a transmission part is connected between the rotating wheel and the gear. The gear can be driven to rotate by stirring the rotating wheel, and the air inlet pipe can be driven to move when the gear rotates, so that the flexible hammer is driven to move.

Further, the sleeve is iron, and fixed column tip is provided with magnet. Magnet can adsorb on the sleeve, has increased the fixed stability of flexible hammer.

Furthermore, a sweat absorbing pad is arranged on the outer surface of the handle. The sweat absorbing pad can absorb sweat of the hands of a doctor, and the hands of the doctor and the handle are prevented from slipping.
