Abstract
The utility model relates to a continuous micro-wound liquid-air draining/feeding puncture outfit. The structure is that the puncture outfit consists of a puncturing trocar and a unidirectional flow device, and the puncturing trocar consists of a trocar core and a trocar guard sheathed on the needle core. Two ports of the triple body of the unidirectional flow device are respectively connected with a one-way valve, wherein a one-way valve is connected with the trocar guard of the puncturing trocar. The utility model does not need to incise the patient's skin, and directly pierces the puncturing trocar into the patient's chest (belly) cavity after local anesthesia. The trocar core is extracted and the silica gel conducting sleeve tube of the trocar guard is left in the patient's body, being used for injecting drug to the body or connecting the unidirectional flow device to use the hypodermic syringe connected with the unidirectional flow to continuously abstract the liquid (air) in the body and does not need to stitch after tube drawing. The puncturing outfit has advantages of easy and simple operation, easy fixation, small injury and no complaints, and the puncturing outfit can effectively avoid the cross infection and blemish to the intracavity organs.
Description
Technical field
This utility model relates to a kind of medical thrust device, and particularly a kind of Wicresoft continues liquid, gas extraction perforator.
Background technology
In clinical, the apparatus that is used for extraction patient foot chamber hydrops (gas) and seroperitoneum is still for continue the common puncture needle that uses for many years always, this puncture needle only is made of a steel hollow needle and the needle handle that is connected with this hollow needle one end, during use, needing to adopt one by one, end is connected with needle handle, the other end connects the silica gel tube of syringe, utilize syringe to extract and suffer from intravital liquid (gas) body, because during operation, syringe can't once be extracted liquid in it (gas) body out, adopt mosquito forceps clamp silica gel tube so take out Man Houxu, remove syringe and release in the syringe behind liquid (gas) body, will connect syringe aforesaid operations repeatedly once more, it is not only operated wastes time and energy, and increased the chance of patient's cross infection, simultaneously, the steel puncture needle very easily damages foot (abdomen) chamber internal organs, can not keep somewhere, so each extraction all needs puncture again, and breast (abdomen) portion is damaged repeatedly, patient also is difficult for accepting.And gas foot closed drainage often adopts the hard conduit of the about 1cm of internal diameter at present, by the surgical incision thoracic wall, insert conduit and sew up reservation, the method not only wound is big, conduit and histocompatibility are poor, merge subcutaneous emphysema easily, and, behind the tube drawing even need sew up wound, just can avoid occurring iatrogenic gas human hair combing waste and give birth to.
The utility model content
This utility model is at the technical problem that exists in the background technology, provide a kind of easy and simple to handle, safe in utilization, wound is little, no pain and can the one-pass operation process and the Wicresoft of inlying catheter continue liquid, gas extraction perforator.
Its concrete solution is: constitute this perforator by paracentesis trocar and one-way flow device.And, paracentesis trocar is made of needle guard and nook closing member, wherein, the needle guard that is made of drain sleeve pipe and toggle is socketed on the nook closing member, and the puncture needle end of nook closing member is placed outside the drain sleeve pipe, and needle handle one end of nook closing member places outside the toggle, so that behind inserting needle and the inserting needle nook closing member is extracted out, and the two-port of one-way flow device triple-valve body is connected with a check valve respectively, and wherein a check valve is connected with the needle guard toggle of paracentesis trocar.
In addition then, the telescopic end of drain is provided with side opening, and what this drain sleeve pipe adopted is soft silica gel material, and the nook closing member employing is the steel puncture needle.
When this utility model uses, do not need the patient skin otch, can directly puncture casing be needled into patient's breast (abdomen) chamber after the local anaesthesia, extract nook closing member and the silica gel drain sleeve pipe of needle guard is retained in suffers from the body, utilize liquid (gas) body in the syringe continuous drawing body that is connected with the one-way flow device after being used in body injection or connecting the one-way flow device, and need not stitching behind the tube drawing.This puncture needle is easy and simple to handle, easily fixing, little, the no pain of wound, and can effectively avoid the damage of cross infection and intracavity internal organs, and be suitable in the pneumothorax closed drainage, using.
Description of drawings
Fig. 1 is this utility model paracentesis trocar structure chart.
Fig. 2 is the johning knot composition of this utility model paracentesis trocar needle guard and one-way flow device.
The specific embodiment
Among Fig. 1, the drain sleeve pipe of needle guard 2 and what be connected that the toggle 3 of drain sleeve pipe 2 one ends adopts respectively is soft silica gel tube and hard gel material.And an end of drain sleeve pipe 2 is provided with two drains side opening 1.Nook closing member is made of puncture needle 4 and needle handle 5, and wherein, puncture needle 4 is a hollow steel pin.Needle guard and nook closing member socket, and the point position that makes puncture needle (4) one ends after the socket is outside drain sleeve pipe 2, the afterbody of needle handle 5 places outside the toggle 3, thus the paracentesis trocar that uses when constituting inserting needle.The two-port of the triple-valve body 8 in Fig. 2 one-way flow device is connected with a check valve 7,10 respectively, and wherein check valve 7 is pegged graft with needle guard 6, uses during for extraction patient's foot (abdomen) chamber liquid (gas) body.
During puncture, do not need skin incision, paracentesis trocar directly can be thrust breast (abdomen) chamber after the local anaesthesia, when pumpback has liquid (gas) body, extract nook closing member needle guard 6 is kept somewhere, can the intracavity injection.During as need extraction hydrops (gas), the check valve 7 of one-way flow device is connected with needle guard 6, and take out the blocking piece 9 that the triple-valve body port connects, connect a syringe in this port and one container is set at check valve 10 places, can utilize syringe that check valve 7 is opened, check valve 10 closures make in liquid (gas) the body suction syringe.During the pushing syringe bolt, check valve 7 closures, check valve 10 is opened, and the interior extract of syringe is injected in the container.So repeatedly, reach the purpose of continuous extraction liquid (gas) body.
Claims (2)
1, a kind of Wicresoft continues liquid, gas extraction perforator, it is characterized in that constituting by paracentesis trocar and one-way flow device, and, paracentesis trocar is made of needle guard (6) and nook closing member, wherein, the needle guard that is made of drain sleeve pipe (2) and toggle (3) is socketed on the nook closing member, and puncture needle (4) end of nook closing member is placed outside the drain sleeve pipe (2), and needle handle (5) one ends of nook closing member place outside the toggle (3), and the two-port of one-way flow device triple-valve body (8) is connected with a check valve (7) respectively, (10), wherein check valve (7) is connected with the needle guard toggle (3) of paracentesis trocar.
