Description

Closed thoracic sleeve pipe drainage needle

Technical field

This utility model belongs to a kind of medical apparatus and instruments, and concrete is a kind of apparatus that is used for chest drainage.

Background technology

Vehicle accident in recent years rolls up, the hemopneumothorax showed increased that vehicle accident causes, and Traumatic Hemopneumothorax is sick and wounded is not only wartime, has also become common emergency case at ordinary times.After hemopneumothorax took place, negative pressure became malleation in the pleural space, caused vein to return painstaking effort stream and was obstructed, and the cardio-pulmonary function obstacle that the generation degree is different, severe patient heart rate can occur and accelerate blood pressure drops, even shock or death by suffocation.The Traumatic Hemopneumothorax traumatic condition is serious, development rapidly, as treat untimely, can be rapidly because of breathing, circulatory failure dead [.Normal is the topmost cause of death of wartime and vehicle accident.

How as early as possible, safe and effective to carry out aerofluxus, liquid be the key that improves patient's salvage success rate.Traditional aerofluxus, the therapy of discharge opeing have two kinds: a kind of is pleurocentesis, inserts the thoracic cavity with thoracentesis needle, extracting gases, liquid.That the advantage of this method is is simple to operate, relatively safety, patient's wound little, should not cause the negative property pulmonary edema of opening, cause that complication such as hemothorax and infection are less.But the effective sex ratio of its treatment hemopneumothorax is relatively poor, be difficult to gas, liquid are extracted totally, often need every day or extraction every other day, strengthened doctor's workload, increased the weight of patient's misery, and when lung is opened again, easily caused lung to be punctured pin damage once more and cause iatrogenic pneumothorax; Another kind method is to select closed drainage of thoracic cavity operation for use, selects for use thick drainage tube to insert the thoracic cavity, can effectively get rid of thoracic cavity blood, gas.But this kind method complicated operation often needs to cut skin, separates the flesh layer, brings new wound and misery to the patient.Thick drainage tube also can cause the pain of patient's severe postoperative, need to use analgesic, and can cause the subcutaneous hematocele of patient, pneumatosis, infection of incisional wound, thoracic cavity infection, a series of complication such as opening property pulmonary edema again.And this method complex operation, the time spent is longer, is unfavorable for field first aid, and large hospital just can be operated, thereby usually incurs loss through delay rescue opportunity, has increased mortality in said patients.

Present scholar both domestic and external makes the advantage that ins all sorts of ways in conjunction with both, aspect puncture needle and drainage tube, adopts venous cannula pin or deep vein puncture pin to replace, and has obtained certain effect.But also find to exist following shortcoming: 1, the venous cannula needle material is rolled over easily and is closed, and lacks flexibility, and can only put pipe again after folding closes; 2, the venous cannula pin does not have gaging hole, relatively poor, the also obstruction easily of drain, blood drainage weak effect.Therefore, the drainage needle that needs the portable first-aid thoracic duction instrument use of a kind of architecture advances of proposition.

The utility model content

The purpose of this utility model is in order to solve the problems of the technologies described above, a kind of closed thoracic sleeve pipe drainage needle is proposed, be used for the portable first-aid pleural cavity closed drainage device, difficulty simplifies the operation, shorten rescue time, reduce the generation of complication, thereby reach the breath cycle obstacle that rapid solution Traumatic Hemopneumothorax is brought, reduce mortality rate.

The purpose of this utility model solves by the following technical programs: closed thoracic sleeve pipe drainage needle, be provided with nook closing member, sleeve pipe, it is characterized in that: described nook closing member is made of the syringe needle and the needle handle of normal injection needle head structure, this needle handle is a hollow tubular, front end and syringe needle are sealedly and fixedly connected, and the rear end is an opening; Described sleeve pipe is made of body and pipe handle, flexible and flexible, the not easy to break non-toxic material that closes of body apparatus is made, hollow tubular, the external diameter of its internal diameter and described syringe needle matches, and the front port wall is thin, be provided with side opening, the rear end is provided with the hollow pipe handle that is tightly connected, and body is enclosed within the syringe needle outside, and the tip of syringe needle stretches out the body front end, the body front port is held syringe needle tightly, and rear end pipe handle and needle handle front end are pegged graft.

A capping is housed in the open rearward end of described needle handle.

The rear end outer surface of described needle handle is provided with fastening rib, makes things convenient for the grafting drainage tube.

Indication is spontaneous pneumothorax, iatrogenic pneumothorax, traumatic hydropneumothorax.Operating process: select between patient's side second rib after clearly having pneumothorax, behind the sterilization skin, this utility model is thrust after pumpback has gas behind the thoracic cavity, pull out nook closing member, pad pasting fixed cover bobbin, makes gas, liquid can only go out to drive in the wrong direction and enters with the needle handle rear port connection bivalve film check valve-type vacuum suction bottle of drainage tube from drainage needle in thoracic wall, prevent retrograde infection, get rid of intrathoracic gas and liquid rapidly.

Drainage needle of the present utility model has the following advantages: 1, simple to operate, be easy to Medicine and Surgery, the doctor of emergency department on top of; 2, prepare before the art to lack, the operating time is short, generally is no more than 1 minute, can solve patient's misery as early as possible, saves patient's life; 3, saved doctor's workload, do not needed repeatedly breast to wear, reduced a large amount of breasts repeatedly and wear the time; 4, alleviated patient's breast misery of wearing repeatedly; 5, postoperative complication, side effect obviously reduce, and have reduced the subcutaneous emphysema of closed drainage of pleural cavity, the side effect of infection, and patient's postoperative does not have pain perception, need not take analgesic, have also avoided thoracentesis needle to cause the shortcoming of lung tissue damage simultaneously; Need not anaesthetize when 6, patient's state of an illness is heavier; 7, expense is cheap.
