Fig. 1 is the structural representation of this utility model one embodiment.
Fig. 2 is the structural representation at drainage tube interface place.
Fig. 3 is the structural representation that negative-pressure suction pipe takes out instrument.
Detailed description of the invention
As shown in Figure 1, Figure 2 and Figure 3, the present embodiment proposes a kind of drawing out type deep wound negative pressure closed drainage device.Comprise and to be arranged on wound surface 1 for adsorbing the dressing 2 of the shallow table sepage of wound surface, be arranged at the sealing biological semi-permeable film 3 in dressing 2 and seal with biological semi-permeable film 3 negative pressure drainage device be communicated with.
Negative pressure drainage device comprises negative pressure power source (not shown), negative-pressure suction pipe 4 and the negative pressure sucker 5 for sealing connection negative-pressure suction pipe 4 and dressing 2.In order to ensure the sealing effectiveness between negative pressure sucker 5 and biological semi-permeable film 3, the bottom design of negative pressure sucker 5 is the caliber being greater than negative-pressure suction pipe 4.
As shown in Figure 1, biological semi-permeable film 3 is also provided with an interface 7 inserted for drainage tube 6, in interface 7, is provided with the passage worn for drainage tube 6.The dressing 2 coordinated with interface 7 is provided with the passage worn for drainage tube 6.Wherein, being provided with between interface 7 and biological semi-permeable film is tightly connected uses drainage tube sucker, and in the present embodiment, drainage tube sucker and negative pressure sucker are structure as a whole.
In other embodiments, also drainage tube sucker and negative pressure sucker independently can be arranged.
Owing to having additional the interface inserted for drainage tube in dressing and biological semi-permeable film, as required the drainage tube of different size, different structure can be inserted therein during use and realize different functions., after drain completes, drainage tube can be removed when not moving dressing and biological semi-permeable film, reducing the replacement frequency of drainage system, reduce the probability of wound surface cross infection, and structure is simple meanwhile, easy to operate.
As shown in Figure 2, the outside of interface 7 is also provided with access flap 8, and access flap 8 and interface 7 are tightly connected.For the ease of the connection between interface 7 and external piece, there is external screw thread in the arranged outside of interface 7.The outside of interface 7 is also provided with the access flap 8 that can be combined on interface 7, and the female thread of access flap 8 matches with the external screw thread of interface 7.Therefore, when not needing degree of depth drain, can drainage tube be extracted, access flap being combined on interface, allow whole device still closed state, block the chance that wound surface contacts with external environment, reduced the probability of traumatic infection, shorten treatment time.
As shown in Figure 3, for the ease of being taken out from the passage dressing 2 by drainage tube, the inner side of interface 7 being provided with female thread 71, being also provided with drainage tube in the outside of interface 7 and taking out instrument 9.The end that drainage tube takes out instrument 9 is provided with the external screw thread 91 coordinated with the female thread 71 of interface.When needs take out drainage tube 6, the external screw thread 91 drainage tube being taken out instrument 9 screws in the female thread 71 of interface 7, then outwards extracts out, easy to operate, quick, significantly reduces the impact on the negative pressure in dressing when getting drainage tube.
In other embodiments, being tightly connected between interface and access flap also can adopt other the known connected modes except being threaded.
The wall of drainage tube 6 is provided with multiple side opening 61.Owing to being provided with multiple side opening on drainage wall, under the effect of negative pressure, slough in wound surface or transudate direction as shown by the arrows in Figure 1, be inhaled into from different directions in drainage tube, thus planar drain and deep drain are changed in traditional point-like drain or local drainage, improve drainage effect, shorten drainage time, and then shorten the time that drainage tube inserts wound surface, accelerate the speed of wound healing.
Due to the foamed materials that polyurethane sponge is a kind of porous, the soft high resilience of quality, have good plasticity and breathability, therefore, the present embodiment preferably adopts polyurethane sponge as dressing.
Embody rule situation of the present utility model is as follows:
Step one, the placement of drain.1. debridement: downright bad devitalized tissue or easily downright bad tissue, abnormal secretion thing and the foreign body etc. of thoroughly removing wound surface, open all lacunas, guarantee the blood confession of soft tissue and osseous tissue, the skin around cleaning wound surface.2. prepare drain: the size and shape pressing wound surface, prune the dressing inserted for drainage tube and negative-pressure suction pipe.The sidewall of drainage tube is provided with multiple side opening.The direction that drainage tube goes out pipe is sealed into principle to facilitate drainage tube.3. fill: cover and fill dressing, dressing is sewed up fixing, make the complete flap coverage of dressing.When wound surface is darker, dressing need be filled to bottom, in wound surface, stay dead space.
Step 2, closes.Negative pressure sucker is adhered in dressing, then drainage tube is inserted wound surface lacuna, close in dressing and negative pressure sucker outer side covers and use biological semi-permeable film.Wherein interface contacts with biological semi-permeable film phonograph seal.
Step 3, connects negative pressure.One end of negative-pressure suction pipe is sealedly attached to the opening part of negative pressure sucker, another termination negative pressure device.Negative pressure is regulated between-450 to-125mmHg.Judge that the effective standard of negative pressure is that dressing is obviously sunken, under biological semi-permeable film, no liquid is gathered.
Step 4, after guaranteeing that negative-pressure sealed drainage is normal, observes and records character and the quantity of negative pressure condition and effluent.When not needing by drainage tube drain, first closing negative pressure device, opening access flap, take out instrument with negative-pressure suction pipe and take out negative-pressure suction pipe, then access flap be covered on seam and make it be in sealing state, finally opening negative pressure device again.When not needing negative pressure drainage, remove negative pressure drainage device.This device is simple to operate, practical.
Embodiment 2
This embodiment is substantially the same manner as Example 1, and its difference is, access flap is arranged on the inner side of interface, and access flap is connected with sealing joint.
Adopt the drawing out type deep wound negative pressure closed drainage device of this embodiment, when not needing drainage tube, drainage tube is taken out with drainage tube withdrawing device, access flap is covered on seam and makes it be in sealing state, in order to ensure the sealing property between interface and interface, method well known in the art can be adopted to carry out sealed envelope to its junction.
More than describe preferred embodiment of the present utility model in detail.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to design of the present utility model without the need to creative work.Therefore, all technical staff in the art according to design of the present utility model on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should by the determined protection domain of claims.
