SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a wound face continuous flushing pipe to solve when washing internal wound face, need insert two root canals to internal, it is great to patient's injury, patient can be painful problem relatively.
In order to achieve the above purpose, the basic scheme of the utility model is as follows: the wound surface continuous flushing pipe comprises a liquid discharge pipe with one end communicated with a flusher and a return pipe with one end communicated with a negative pressure drainage device, wherein one of the liquid discharge pipe and the return pipe is inserted into the inner cavity of the other pipe to form a sleeve, and the free end of the inner pipe of the sleeve extends out of the free end of the outer pipe.
The theory of operation and the beneficial effect of this basic scheme lie in:
1. when in use, the sleeve is inserted into the body of a patient, and can be used for simultaneously flushing and extracting waste liquid, but only one pipeline is required to be inserted into the body of the patient, so that the pain of the patient is reduced.
2. The inner pipe of the sleeve refers to a pipeline positioned in the sleeve, and the outer pipe of the sleeve refers to a pipeline positioned outside the sleeve. The free end of the inner side pipe of the sleeve extends out of the free end of the outer side pipe, so that liquid in the pipeline in the sleeve can flow out or be pumped out, and the interference of the liquid movement of the two pipelines is avoided.
Further, a drain pipe is inserted into the return pipe.
Has the advantages that: under the condition that the velocity of flow is unchangeable, the flowing back volume of flowing back pipe is relevant with the pipe diameter of flowing back pipe in the unit interval, and the waste liquid extraction volume of back pipe also is relevant with the pipe diameter of back pipe, that is to say, the pipe that the pipe diameter is less, no matter is flowing back or waste liquid is taken out, and its speed can be relatively slow. Therefore, if insert the back flow in the flowing back, the back flow pipe diameter is less than the pipe diameter of flowing back pipe promptly, then the waste liquid speed of taking out is slower than the flowing back speed, and then the flush fluid dwell time is longer in the human body, and the flush fluid volume of getting into is far greater than the waste liquid volume of taking out, and the flush fluid piles up in the human body, leads to patient comparatively painful. In this device, insert the fluid-discharge tube in the return pipe for the speed that the waste liquid was taken out is greater than the flowing back speed, and the flush fluid that will let in internally that can be quick is discharged, avoids the flush fluid to pile up in the human body.
Furthermore, a connecting hole is arranged on the side wall of the return pipe, and the liquid discharge pipe is inserted into the inner cavity of the return pipe through the connecting hole.
Has the advantages that: compare in the fluid-discharge tube inserts the backward flow completely, cause the interference easily to the connection of back flow and negative pressure drainage device, among this device, the lateral wall that the fluid-discharge tube passes through the back flow inserts in the backward flow, makes things convenient for back flow, fluid-discharge tube to communicate with negative pressure drainage device, flusher respectively, mutually noninterfere.
Simultaneously, the connecting hole sets up on the back flow, and in the lateral wall that does not make the back flow pass through the fluid-discharge tube inserted the fluid-discharge tube, because the setting of connecting hole, it is relatively poor to lead to the leakproofness of back flow easily, and the liquid in the back flow is probably takes place to leak through connecting hole department, and what flow in the back flow is the waste liquid, even leak and can not cause great influence yet, nevertheless if set up the connecting hole in the fluid-discharge tube, the leakage of the flush fluid in the fluid-discharge tube then can cause the waste, increases the cost that the wound face washed.
Furthermore, the side wall of the return pipe is provided with a pressure reducing hole.
Has the advantages that: when the negative pressure acting force is too large, the suction force in the human body is large, the pain of a patient is increased, and the arrangement of the pressure reducing holes can be supplemented by external gas, so that the human body is prevented from feeling the large suction force. Meanwhile, when the backflow pipe is blocked in the body, medical staff can not timely perceive and close the negative pressure drainage device, and at the moment, the negative pressure effect can be completely acted at the pressure reducing hole, so that the human body is prevented from being greatly injured.
Furthermore, the inner diameter range of the liquid discharge pipe is 3mm-5mm, and the pipe wall thickness of the liquid discharge pipe is 1mm-2 mm.
Has the advantages that: the pipe diameter of the liquid discharge pipe is prevented from being too large, and the liquid discharge pipe is arranged in the return pipe, so that waste liquid which is easy to interfere with the return pipe is easily pumped out; meanwhile, the phenomenon that the pipe diameter of the liquid discharge pipe is too small, the discharge speed of flushing liquid is too low, and the cleaning effect on the wound surface is poor is avoided.
Furthermore, the side wall of the free end of the return pipe is provided with a plurality of return holes.
Has the advantages that: when the negative pressure is relatively large, the acting force of the waste liquid entering the return pipe is greater than the acting force of the flushing liquid discharged by the liquid discharge pipe, the flushing liquid cannot flush the wound surface and then enters the return pipe 1 under the action of the negative pressure, and therefore the flushing effect is poor; and when the effort that the waste liquid got into in the return line was less than the effort of fluid-discharge tube discharge flush fluid, lead to the waste liquid like this when being close to the free end of fluid-discharge tube, the influence that receives the discharge flush fluid can be broken away, leads to getting into the effect in the return line not good.
In the device, the backflow hole is arranged on the side wall of the backflow pipe, and a part of waste liquid is gathered at the side wall of the backflow pipe under the action of negative pressure and enters the backflow pipe, so that the interference of the waste liquid and flushing liquid discharged by the liquid discharge pipe is reduced. Meanwhile, a part of waste liquid is pumped out through the backflow hole, the acting force of the waste liquid on the free end of the liquid discharge pipe is reduced, and the liquid discharge pipe is prevented from being influenced by the waste liquid and retracting into the backflow pipe.
Furthermore, the part of the liquid discharge pipe, which is positioned outside the reflux pipe, is connected with a limiting ring in a sliding way, and the inner diameter of the limiting ring is equal to the outer diameter of the liquid discharge pipe; the lateral wall of the limiting ring is fixed with a clamping ring, the inner diameter of the clamping ring is equal to the outer diameter of the return pipe, and the liquid discharge pipe and the return pipe are hoses.
Has the advantages that: the fluid-discharge tube inserts in the backward flow, waste liquid in the backward flow receives the negative pressure effect when too big, drive the fluid-discharge tube easily and pass through the connecting hole and outwards slide, the connection of fluid-discharge tube and back flow is unstable promptly, but at the actual in-process of washing, fluid-discharge tube and back flow are disposable article, for avoiding the cost too high, all directly assemble through two pipelines and use, if extra customization, through gluing or other mode fixed connection with fluid-discharge tube and extract tube, the cost is higher.
In this device, with the spacing ring, the fluid-discharge tube is established to snap ring slip cap, on the back flow and with the spacing ring, the snap ring slides to the junction that is close to fluid-discharge tube and back flow, because fluid-discharge tube and back flow are the hose, then when the internal diameter of spacing ring (snap ring) equals fluid-discharge tube (back flow) external diameter, fluid-discharge tube (back flow) can block into in spacing ring (snap ring), when being full of flush fluid (waste liquid) in fluid-discharge tube (back flow), fluid-discharge tube (back flow) are strutted joint that also can be better in spacing ring (snap ring). The junction card with fluid-discharge tube and back flow through spacing ring, snap ring is in the same place, and when flush fluid or waste liquid were full of fluid-discharge tube or back flow in, spacing ring, snap ring were difficult to slide on fluid-discharge tube, back flow, just also avoided the fluid-discharge tube to outwards slide for the connection of fluid-discharge tube and back flow is comparatively firm.
Meanwhile, after the flushing is finished, after no liquid exists in the liquid discharge pipe and the backflow pipe, the limiting ring and the clamping ring can be taken down from the liquid discharge pipe and the backflow pipe, the limiting ring and the clamping ring can be reused when being connected next time, and the use cost is reduced.
Further, the snap ring is an incomplete ring.
Has the advantages that: the incomplete ring is a notch arranged on the ring, when the device is used, the limiting ring only needs to slide on the liquid discharge pipe to a position close to the connection position of the liquid discharge pipe and the backflow pipe, and then the backflow pipe is clamped into the clamping ring through the notch of the clamping ring. Compare the snap ring and be complete ring, need snap ring and spacing ring to slide longer distance on back flow, fluid-discharge tube simultaneously, the slip process is comparatively troublesome, designs the snap ring for incomplete ring in this device, then connects more conveniently.
Furthermore, the snap ring is a three-quarter circular ring.
Has the advantages that: the situation that the clamping effect on the return pipe is poor due to the fact that the notch of the clamping ring is too large is avoided; and the situation that the return pipe is difficult to be clamped into an incomplete ring due to the fact that the notch of the snap ring is too small is also avoided.
