Description

Special drainage instrument for cardiology

Technical Field

The utility model relates to the technical field of medical tools, concretely relates to special drainage appearance of intracardiac branch of academic or vocational study.

Background

Most of the existing drainage devices special for cardiology department adopt syringes to pump off the concentrated water in the heart, after the syringes are filled with the concentrated water, the syringes need to be taken out from the inside of the human body, the syringes are replaced again to pump the concentrated water, and the needles enter the inside of the human body for many times, so that the treatment time is prolonged, and the pain of patients is aggravated.

On the basis, medical tools are continuously new, and various novel drainage tools are designed, for example, a patent of "a drainage device special for medical cardiology department" (CN210250690U) issued at present discloses a novel drainage device, which specifically discloses that "when the insertion mechanism is inserted into the heart, the suction mechanism is pulled to generate negative pressure inside the suction mechanism and the second installation mechanism, the thick water in the body is sucked into the storage mechanism through the insertion mechanism and the first installation mechanism, when the storage mechanism is full, the second valve is rotated to seal the first installation mechanism and the second installation mechanism, the screw is rotated to separate the screw from the first installation mechanism and the second installation mechanism, so that the storage mechanism is taken down from the handle, and the thick water in the storage mechanism is cleaned, the storage mechanism is connected with the first mounting mechanism and the second mounting mechanism again, so that concentrated water can be pumped again, the use is convenient, the treatment time is shortened, the insertion mechanism is prevented from entering the body for multiple times, and the pain of a patient is relieved, although the technical problem that the needle head enters the human body for multiple times can be solved, other defects exist in clinical practice, and the defect causes the situation that the technical scheme of the granted patent has poor feasibility, and the defect of the drainage tool is explained as follows:

this kind of drainage device is in the use, need to be guaranteed by medical personnel to be used for holding the interior dense water's of heart storage box volume and enough to hold the required extraction dense water, however in the actual operation in-process, the storage box often appears the thick water and accumulates the condition too much and can't in time get rid of, storage box adopts the dismantlement separation in addition, the processing method who pours out the dense water again, the loaded down with trivial details work load of medical personnel has been increased to a certain extent, and if medical personnel is in the in-process of the extraction to the dense water, storage box is full of the dense water, then need again to dismantle the separation to storage box, after pouring out the dense water, again with storing the box reinstallation, this process will increase the treatment time to the patient, and the syringe needle can't be pulled out again in this process, then probably because of external uncontrollable factor, and increase the possibility that causes the secondary injury to the patient.
