Description
Technical field
This utility model belongs to medical instruments field, is specifically related to a kind of disposable nested type closed thoracic drainage tube.
Background technology
Closed thoracic drainage tube need be inserted in thoracic operation or post-traumatic needs of patients thoracic cavity, makes drainage-fluid flow out external through closed thoracic drainage tube.But current used closed thoracic drainage tube is only a flexible pipe, and its one end is inserted in thoracic intracavity, and the other end is positioned at outside patient body, and is connected with closed drainage bottle by union joint, form enclosed construction.In the time that needs carry out administration to thoracic intracavity, one method is: medical personnel pull out union joint, medicine is directly poured in flexible pipe, make medicine flow into patient thoracic cavity along flexible pipe, and in the time of administration in order to prevent that thereby air from entering flexible pipe and causing patient's pneumothorax, medical personnel want the in good time different parts that pinches flexible pipe in the time that medicine is poured into flexible pipe, and operation easier is larger, often needs multi-person synergy complete operation; Use in addition same passage simultaneously as effuser and the delivery tube of drainage-fluid, the risk of patient's retrograde infection is increased; Secondly the position of administration and the time of staying of medicine can accurately be not controlled, affect drug effect.Another kind method is that patient is punctured separately, penetrate an other flexible pipe and carry out administration, although this method has reduced the risk of retrograde infection, but puncture can increase patient's misery greatly again, and the position of twice puncture needs strict control, if put pipe through same puncturing hole, air likely enters patient thoracic cavity from the gap forming between two flexible pipes, thereby causes patient's pneumothorax.
Utility model content
The purpose of this utility model is to provide a kind of disposable nested type closed thoracic drainage tube, use this disposable nested type closed thoracic drainage tube to carry out breast intracavitary administration to patient easily, reduce operation easier, reduce the risk of retrograde infection and pneumothorax, can not increase patient's misery simultaneously.
For achieving the above object, this utility model adopts following technical scheme:
A kind of disposable nested type closed thoracic drainage tube, comprise the outer tube for closed drainage of pleural cavity of both ends open, the top of outer tube be connected for the adapter being connected with drainage bottle, in outer tube, be set with both ends open for to the inner tube of thoracic cavity administration, stretch out from the bottom of outer tube the bottom of inner tube, the top of inner tube passes from the tube wall on outer tube top, and the top of inner tube is provided with the joint for being connected with administration device, and dismountable sealing cap is housed on joint.
The length of described outer tube is 40～45cm, and external diameter is 10～12mm, and internal diameter is 8～10mm.
The external diameter of described inner tube is 2～3mm, and the length that inner tube is stretched out the part of outer tube bottom is 10～15cm, and the length that inner tube passes the part of outer tube wall is 1～2cm.
The part that described outer tube is passed by inner tube is provided with for preventing that gas from entering the hermetically-sealed construction of outer tube;
Described hermetically-sealed construction is 10～15cm apart from the length on outer tube top.
Scale is carved with in described outer tube middle part to the tube wall of bottom part.
The length of described scale is 30～35cm.
Described outer tube bottom offers side opening.
The number of described side opening is 2～3.
Described outer tube is made up of silica gel material; The bottom of outer tube is provided with chamfering.
Described adapter is provided with the control valve of the rate of outflow of controlling drainage-fluid.
With respect to prior art, the beneficial effects of the utility model are:
This utility model provides a kind of disposable nested type closed thoracic drainage tube, comprise outer tube and be sleeved on inner tube wherein, this disposable nested type closed thoracic drainage tube is inserted behind patient thoracic cavity, pneumatosis hydrops in patient thoracic cavity flows out by outer tube, medical personnel by inner tube to thoracic intracavitary administration, like this fluid partitioning that goes out, enters is opened, can be reduced the risk of patient's retrograde infection, and can reduce to the operation easier of thoracic intracavitary administration.And because stretch out from the bottom of outer tube the bottom of inner tube, therefore inner and outer pipe is inserted behind patient thoracic cavity, medicine-feeding part is different with drain position, action time that can prolong drug, improve curative effect, and can come to control comparatively accurately by controlling the insertion depth of outer tube the administration position of inner tube.Also, because inner tube is set with within the outer tube, in the time inserting outer tube, also insert inner tube, do not needed to carry out secondary puncture, can not increase patient's misery, do not affected drainage effect simultaneously.In addition, in the time not needing administration, sealing cap is arranged on the joint on inner tube top, can avoids air to enter thoracic intracavity by inner tube, reduce the risk of patient's pneumothorax.Therefore this utility model is a kind of simple in structure, safe and reliable, easy to operate, practical and multi-functional closed thoracic drainage tube.
Further, the part that the outer tube in this utility model is passed by inner tube is provided with for preventing that gas from entering the hermetically-sealed construction of outer tube, can avoid air to enter thoracic intracavity by outer tube, reduces the risk of patient's pneumothorax.And outer tube middle part is carved with scale to the tube wall of bottom part, can make doctor convenient, grasp outer tube accurately and be inserted in the intrathoracic degree of depth of patient.And outer tube bottom offers side opening, can make drainage-fluid more easily flow in outer tube and then discharge.The bottom of outer tube is provided with chamfering, can be convenient to the insertion of outer tube.Outer tube is made up of silica gel material, makes it have elasticity and pliability.Adapter is provided with control valve in addition, can control the rate of outflow of the mixed liquor of the intrathoracic drainage-fluid of patient, medicine or drainage-fluid and medicine, thereby controls medicine in the intrathoracic time of staying of patient.
