Abstract
The utility model relates to a medical thoracic cavity drainage tube, which is mainly composed of a tube body and a tube head. The tube head is an umbrella-shaped tube head; the side wall of the umbrella-shaped tube head is provided with a drainage hole; a convex lug boss is formed on the connecting position of the tube head and the tube body. After arranged in the thoracic cavity, the convex lug boss can be tightly contacted and arranged on the inner side of the thoracic cavity, playing the functions of fixing and limiting the tube head. The drainage tube has the advantages of accurate position, less complication, convenient operation and easy control. The utility model is particularly suitable for field conditions and no thoracic surgery professionals.
Description
This utility model relates to a kind of medical drainage equipment.
Existing intrathoracic drain is simple straight tube form, and its head is made duck and chewed type, has conduction hole on the sidewall.The drainage tube head injects the thoracic cavity during use, and intrathoracic liquid or gas enter drainage tube by the conduction hole on tube head and the sidewall and discharges.The shortcoming of this straight tube-like drainage tube is be difficult for to place correctly, puts the pipe depth and is difficult for grasping, and fixing difficulty comes off easily, particularly to non-thoracic surgery professional or reach not open under the breast situation all the more so in field condition.Because the position of drainage tube is difficult for fixing, the conduction hole of tube head sidewall may move outward and facing to the thoracic wall tissue, drain gas be introduced the thoracic wall tissue and caused subcutaneous emphysema; The position of drainage tube is forbidden also to be difficult to reach up hill and dale the drain of liquid (gas) body is come out, and influences the lung expansion.In addition, the fixing and duck of the drainage tube head of chewing type also can cause the diaphram friction to cause pain, hemorrhage and influence expectoration.
The purpose of this utility model is the above-mentioned shortcoming that overcomes existing straight pipe type intrathoracic drain, and a kind of convenience, accurate positioning, fixing reliable, sufficient medical intrathoracic drain of drain of inserting is provided.
The purpose of this utility model is to improve this technical scheme by the head to existing drainage tube to realize.The main composition of drainage tube comprises pipe shaft, tube head two parts, and the tube head sidewall has conduction hole.Described tube head is a umbrella tube head, and the junction of this umbrella tube head and pipe shaft constitutes an evagination boss.In use, pull back slightly after the umbrella tube head is inserted, its evagination boss is leaned against on the thoracic wall medial surface, play the effect of fixed diversion pipe and qualification tube head position.Thoracic wall is close at the tube head rear portion that is the evagination boss, guaranteed conduction hole on the tube head sidewall be in all the time do not understand in the drainage lumens outer move relative with the thoracic wall tissue, thereby can avoid the generation of subcutaneous emphysema complication to greatest extent.
This utility model is compared with existing straight tube-like drainage tube, has the following advantages:
1, easy to use, operating technology requires lowly, is particularly suitable under the field condition and the outer training personnel of non-breast use;
2, the design of umbrella tube head has guaranteed that drainage tube is fixing reliable, difficult drop-off, and simultaneously, the design of the arc of umbrella tube head has also been avoided causing residual cavity and has been stimulated and caused pain every flesh;
3, fixing tube head spacing and that be close to thoracic wall has fundamentally avoided gas is imported the probability of thoracic wall tissue, thereby has also avoided the probability of subcutaneous emphysema complication generation.
Content of the present utility model further illustrates with the following Examples, but content of the present utility model is not limited only to content related among the embodiment.
Fig. 1 is the structural representation of drainage tube among the embodiment.
Fig. 2 is the A-A cutaway view of Fig. 1.
Shown in Fig. 1～2, the drainage tube among the embodiment comprises pipe shaft 1 and tube head 2.Tube head 2 is one to be the tube head of umbrella, and the junction between itself and the pipe shaft 1 constitutes an evagination boss 3.On the sidewall of tube head, have the conduction hole 5 that communicates with inner cavity of tube body 4.In addition, have water conservancy diversion recessed 6 with the conduction hole for end point on the tube head surface.During work the tube head 2 of drainage tube is inserted in the thoracic cavity, make its evagination boss 3 by being attached on the thoracic wall medial surface, desire drain liquid (gas) body in the thoracic cavity then imports conduction holes 5 by diversion groove 6, within pipe shaft 1 outside 4 lead bodies of chamber.The purpose of setting up diversion groove 6 in the present embodiment is to make desire drain liquid (gas) body flow into conduction hole 5 more smoothly.
Claims (2)
1, a kind of medical intrathoracic drain is made of pipe shaft and tube head, and the tube head sidewall has conduction hole, it is characterized in that described tube head is a umbrella shape tube head, and this umbrella shape tube head and pipe shaft junction constitute an evagination boss.
2, medical intrathoracic drain as claimed in claim 1 is characterized in that it is the diversion groove of low spot that described umbrella shape tube head surface offers with the conduction hole on its sidewall.
