Description

Lung abscess treatment auxiliary device

Technical Field

The invention relates to the field of medical equipment, in particular to an auxiliary device for treating lung abscess.

Background

The lung abscess is a lung suppurative lesion caused by various microorganisms such as bacteria, fungi or amebiasis histolytica, is mostly a focal lesion, is not easy to absorb by self, and is easy to aggravate infection and respiratory failure of a patient if not discharged in time, so that the patient finally dies. In addition, the patient with lung abscess can not reach effective concentration in lung by using antibiotics in the whole body, thus affecting anti-infection effect and aggravating metabolic burden of liver and kidney of body. The pulmonary vessels and lymphatic systems are abundant, the lung abscess is removed by an operation, the systems are easy to damage, complications such as atelectasis, hemopneumothorax and the like can be caused, in addition, patients suffer pain, the body damage is large, the treatment cost is high, and the pus is easy to spread to cause systemic infection. Therefore, the lung needs to be punctured and pus is discharged, the pain of the patient is relieved, the wound is small, and the probability of systemic infection is reduced. Meanwhile, antibiotics are injected into the lung abscess focus, so that the concentration of the local antibiotics is improved, and the anti-infection effect is effectively achieved. The lung abscess puncture bag which is commonly used for placing pus clinically at present has the following defects: the number of the included apparatuses is large, the price is high, and the burden of the patient is increased; the repeated use is easy to cause nosocomial infection; when in use, the utility model needs to be matched by a plurality of people, occupies more hands, and uses a syringe to extract pus, thus the labor intensity of doctors is higher; the volume quantity of the extracted pus can not be directly observed, and the total volume quantity can be estimated only after the extraction times are calculated, so that the method is very troublesome and inaccurate; antibiotics cannot be injected directly into lung abscesses. The defects determine that the currently used lung abscess puncture bag cannot meet the clinical requirement.

Disclosure of Invention

The invention aims to provide an auxiliary device for treating lung abscess, and aims to solve the problem that antibiotics cannot be directly injected to an affected part in time after pus is pumped out in the existing lung abscess treatment process.

In order to achieve the purpose, the basic technical scheme of the invention is as follows: the lung abscess treatment auxiliary device comprises a puncture mechanism, a collection mechanism, an intermittent shunt mechanism, a medicine storage mechanism and a power mechanism, wherein the puncture mechanism comprises a support sheet, a pus pumping pipe and a medicine injection pipe; the power mechanism comprises a transmission gear, the intermittent shunting mechanism comprises a transmission gear ring, and the transmission gear is meshed with the transmission gear ring.

The principle of the scheme is as follows: during practical application, store up medicine mechanism and be used for depositing the antibiotic, collect the mechanism and be used for depositing the pus and make statistics of the volume of taking out from the patient is internal, power unit is used for providing the power of suction and the power of injection antibiotic, puncture mechanism is used for the puncture to get into the internal suction and the injection of antibiotic that are convenient for carry out the pus of patient, intermittent type reposition of redundant personnel mechanism is used for intermittent type nature timing to carry out the suction and the injection of antibiotic to the pus to make suction and injection form precedence order, be convenient for in time inject the antibiotic in the affected part after the pus suction. The support sheet is used for puncturing into the lung, and simultaneously, the support sheet is used for supporting the pus pumping tube and the medicine injection tube to ensure that the pus pumping tube and the medicine injection tube can accurately reach the affected part under the operation. Power unit forms the negative pressure and then draws out the pus way and draw out the pus pipe and aspirate the pus of wound in collecting the mechanism, power unit forms the malleation simultaneously and passes through the injection way with the antibiotic in storage medicine mechanism, the injection pipe is injected the wound of getting rid of the pus, power unit passes through the meshing of drive gear and transmission ring gear and through chooseing for use different modulus, the drive ratio, make the pus way of drawing out in the intermittent type reposition of redundant personnel mechanism, the intermittent type of medicine way of annotating switches on, be convenient for carry out the extraction of wound pus and the injection of antibiotic regularly to the in-process that lung abscess patient treated.

The scheme has the advantages that: 1. the pus can be directly sucked and the antibiotics can be directly injected to the affected part in the treatment process of the lung abscess, so that the treatment progress can be accelerated, the anti-infection effect can be improved, and the treatment effect can be improved; 2. the power mechanism is used for providing continuous power to extract pus and inject antibiotics, and compared with the traditional manual operation, the labor intensity is lower.
