An interventional puncture device

Abstract

The invention discloses an interventions puncture device and relates to the field of medical instruments. The problem that existing thoracocentesis hydrops sampling is troublesome is solved. The puncture device comprises a three-way bulb, a first interface of the three-way bulb is connected with a puncture needle, a second interface opposite to the first interface is connected with a hydrops obtaining tube, the tail end of the hydrops obtaining tube is communicated with a disposable hydrops bottle, a third interface of the three-way interface is connected with a sampling tube, a first control valve is arranged on the sampling tube, a connector is arranged at the tail end of the sampling tube, a tube body of the hydrops obtaining tube is provided with an insertion base in insertion fit with the connector, the insertion base is internally provided with a reflux channel communicated with the hydrops obtaining tube, and a second control valve is arranged on the reflux channel. When the interventions puncture device is used for thoracocentesis hydrops sampling, pleural effusion can be taken out through the hydrops obtaining tube, a detection sample of pleural effusion can be synchronously taken out through the sampling tube, people only need to connect the sampling tube to the hydrops obtaining tube after sampling, sampling and hydrops obtaining are easy and convenient, and secondary interventions puncture is not needed.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an interventional puncture device which is simple and convenient for sampling and taking liquid, and does not require secondary puncture intervention. Background technique [0002] Lung abscess is a purulent lesion in the lungs caused by various microorganisms such as bacteria, fungi, or amoeba histolytica. Most of them are focal lesions. The pus is not easy to absorb by itself. If it is not released in time, it is easy to aggravate the patient's infection and respiratory failure , eventually leading to the death of the patient. In addition, the systemic use of antibiotics in patients with lung abscess cannot achieve effective concentrations in the lungs, which affects the anti-infection effect and increases the metabolic burden of the body's liver and kidneys. Pulmonary blood vessels and lymphatic system are rich. Surgical resection of lung abscess is easy to damage the above sys...

AI Technical Summary

Problems solved by technology

At present, the lung abscess puncture kit commonly used to release pus has the following disadvantages: it contains more instruments, which are more expensive, which increases the burden on patients; repeated use may easily cause nosocomial infection; it requires the cooperation of multiple people and takes up more manpower. Many, using a syringe to extract pus, the doctor's labor intensity is relatively high; the volume of the extracted pus cannot be directly observed, and the total volume can only be estimated after calculating the number of extractions, which is very troublesome and inaccurate; it cannot be directly injected into the lung abscess injection of antibiotics

The above disadvantages determine that the currently used lung abscess puncture kit can no longer meet the clinical needs, and there is an urgent need for a simple drainage device to discharge pus

[0003] At the same time, the existing puncture needles are all made of stainless steel.

The wound of the stainless steel puncture needle is jagged. Although it is difficult to distinguish with the naked eye, this kind of wound heals slowly and is easy to leave scars. At the same time, the stainless steel material contains metal diffusers, which are easy to contaminate the wound and produce pigmentation. The sharpness of the knife cut will gradually decrease
