UA35206A - The device for the pleural cavity drainage - Google Patents

Abstract

The invention relates to the field of medicine. The device contains of the puncture niddle and the adapter tube with the valve. On the puncture niddle the adapter tube is sticked, which is connected with the valve unit through a t-junction and with the blank flange tube that intended for cavity introducing of medicinal preparations or for connection to aspiration system

Description

The invention relates to medicine, namely surgical drainage devices, and can be used in thoracic surgery and emergency care.

The device chosen as a prototype for draining the pleural cavity is known (A.E. Romanenko,

Chukhryenko D.P., Melnikov B.O. Close damage to chest organs. - Kyiv: Zdorovya, 1982. - 160 p. - ill.). The device contains a puncture needle and an adapter tube with a valve that is inserted through the trocar.

The device works as follows: a puncture needle is inserted into the pleural cavity in order to transfer a closed pneumothorax to an open one, so that there is no disturbance of cardiac activity, then, if there is no bleeding, the puncture needle is replaced with a transition tube, which is inserted through a trocar, and the end is attached to the tube the valve, for example, is made from the finger of a rubber glove, and is immersed in a disinfectant solution. After elimination of air compression of the lungs, the tube is removed.

The features of the prototype that coincide with the essential features of the proposed invention are the presence of a puncture needle and a transition tube with a valve in the device for draining the pleural cavity.

The technical result of the invention consists in increasing the efficiency of drainage with minimal side effects, increasing the reliability of the device and its operational characteristics.

The reasons preventing the achievement of the expected technical result when using it are as follows: the design of the prototype does not allow it to be carried out in a portable version, that is why there is a possibility of injury to the lungs and infection of the pleural cavity when transporting the patient, the possibility of the development of pleuropulmonary shock due to lung emptying. When using the prototype, a person will be significantly limited in movement.

The invention is based on the task of improving the device for draining the pleural cavity by simultaneously carrying out air aspiration, dynamic control of the discharge from the pleural cavity and the introduction of drugs due to the use of a valve box and a tube with a plug, which is connected to a puncture needle, which allows to achieve the expected technical result.

The problem is solved by the fact that in the device for draining the pleural cavity, which contains a puncture needle and a transition tube with a valve, according to the invention, a transition tube is attached to the puncture needle, which is connected to the valve box through a tee and to a tube with a plug intended for administration of drugs into the cavity or for connection to the aspiration system.

Between the set of essential features of the proposed device and the technical result that can be achieved, the following cause-and-effect relationship is manifested: performing a puncture of the chest with a puncture needle with the simultaneous introduction of a transition tube, which is connected to it and communicates with the valve box, allows avoid lung election and pleuropulmonary shock due to constant air aspiration, and the connection to the transition tube through the tube tee with a plug allows simultaneous drainage and administration of drugs, which allows you to avoid, in comparison with the prototype, subsequent changes of drainage, can be used in emergency cases, which makes it possible to achieve the expected technical result: to increase the efficiency of drainage, to avoid unwanted side effects.

The invention is illustrated by graphic material, where Fig. 1 shows a diagram of a device for draining the pleural cavity. Fig. 2-4 shows the diagram of the valve box.

The device for draining the pleural cavity includes a puncture needle 1, a transition tube 2, a tee 3, a tube with a stopper 4, a stopper 5, a valve box 6, which contains a fixing head 7, a base 8, a membrane 9, a cannula 10.

The device works as follows.

When diagnosing valvular pneumothorax, a puncture of the chest is performed with a puncture needle 1, on which a transition tube 2 is attached, which connects through a tee with the valve box 6. The tube 2 has a plug 5, which serves to cover the valve system. The valve box 6 consists of a fixing head 7, which is glued to the base 8, which has a hole connected to the cannula 10, which connects the valve box 6 to the transition tube 2. A rubber membrane 9 is placed on the base 8.

When inhaling, the air that has accumulated in the pleural cavity exits through the valve box

With, which opens only in one direction, excluding the connection of the pleural cavity with the external environment, and thereby preventing the lungs from collapsing.

A tube with a plug 4 is used for the administration of drugs to irrigate the pleural cavity.

Tubes from disposable systems made of pyrogenic rubber are used to make the device for drainage. When delivering a patient to a hospital, a nipple tube can be used for drainage instead of a puncture needle, which is connected to the device in order not to damage the lung tissue. The tube is inserted through the trocar.

The proposed device for draining the pleural cavity was clinically tested in emergency care for patients with tension pneumothorax in field conditions, in surgical departments that were on duty for emergency care.

The application of the device is illustrated by the following examples.

Patient V., 42 years old, medical history No. 6783, was admitted to the emergency room with stab wounds to the chest. A tension pneumothorax was diagnosed. The proposed device for drainage was used, which made it possible to carry out diagnostic control of the discharge from the pleural cavity, to introduce antibiotics.

On the third day, with positive dynamics, the drainage device was removed. The patient was discharged on the 7th day.

The proposed device for draining the pleural cavity can be used at the scene, during transportation, as well as after installation and commissioning, the victim can be transported by any type of transport, i.e., he remains mobile, and without distracting himself from additional expenditure of strength and means of medical personnel. Thus, the proposed device is technological and easy to manufacture, universal in application.
