Description
Technical field
This utility model relates to a kind of medical treatment consumptive materials, specifically a kind of flushable negative pressure drainage dressing that is applied to the treatment of wound surface closed negative pressure drainage.
Background technology
Wound surface enclosed negative pressure treatment technology is on the basis of clinical traditional negative pressure treatment method, wound surface is put the medical sponge body, wound surface seals with biological hyaline membrane, form an airtight drainage system, prevent extraneous bacterial invasion, improve the wound surface microcirculation blood flow velocity, expansion blood capillary, thereby the effect of increase wound surface quickly-healing.Wound surface closed negative pressure treatment technology is the new wound surface treatment technology that development in recent years is got up, and can promote acute and chronic wound healing, comprises acute, chronic, infected wound.The wound surface enclosed negative pressure is treated and was changed one time medicine in general about 3 days.Along with increasing with dry of exudate, sometimes stop up easily the hole between spongy body, cause the spongy body drain obstructed.At present, yet there are no clinically the negative pressure drainage applicator of washing capacity.
Summary of the invention
Technical problem to be solved in the utility model is in order to overcome above-mentioned the deficiencies in the prior art, a kind of simple structure, reasonable is provided, operation, easy to use, spongy body can be in therapeutic process limit flushing, limit drain, the flushable negative pressure drainage dressing of avoiding spongy body to stop up.
The technical scheme in the invention for solving the above technical problem is: a kind of flushable negative pressure drainage dressing, it comprises a spongy body, drainage catheter, irrigating catheter, it is characterized in that: be inserted with double channel catheter in the described spongy body, evenly have some through holes on the duct wall in the described double channel catheter insertion spongy body, the double channel catheter outer end connects drainage catheter and irrigating catheter by threeway.
Be provided with flushing tract and drain tract in the described double channel catheter, have some flushing through holes on the flushing tract tube wall, have some drain through holes on the drainage lumens road tube wall.
Described threeway is provided with two-chamber pore, flushing pore, drain pore, wherein is provided with the flushing tract that a stainless steel tube connects flushing pore and double channel catheter in the two-chamber pore.
The described irrigating catheter other end is connected with joint, is connected with flushing device with convenient, realizes washing capacity.The drainage catheter other end and negative pressure drainage equipment connection carry out negative pressure drainage.
Be inserted with two double channel catheteres in the described spongy body, each double channel catheter outer end connects a drainage catheter and an irrigating catheter by a threeway.
Be inserted with three double channel catheteres in the described spongy body, each double channel catheter outer end connects a drainage catheter and an irrigating catheter by a threeway.
This utility model is owing to be inserted with double channel catheter in spongy body, double channel catheter connects drainage catheter and irrigating catheter by threeway, against existing technologies, can carry out respectively drain and flushing, also can carry out simultaneously drain and flushing.The medical sponge body can be washed in therapeutic process repeatedly, avoids in wound negative pressure treatment process spongy body to occur dry and stops up and cause the generation of the phenomenons such as inadequate drainage.Its structure rationally, and is easy for operation, reduced the number of times of changing dressings, and reduced the probability of clinical infection, the clinical manipulation safe ready.
Description of drawings
Below in conjunction with accompanying drawing this utility model is done to describe further.
Fig. 1 is this utility model structural representation.
Fig. 2 is the structural representation of this utility model double channel catheter.
Fig. 3 is the structural representation of this utility model threeway.
Label among the figure is: 1. spongy body, 2. double channel catheter, 3. threeway, 4. irrigating catheter, 5. joint, 6. drainage catheter, 21. flushing tracts, 22. drain tracts, 31. stainless steel tubes, 32. flushing pores, 33. drain pores, 34. two-chamber pores.
The specific embodiment
As can be seen from Figure 1, a kind of flushable negative pressure drainage dressing, it comprises a spongy body 1, drainage catheter 6, irrigating catheter 4 etc.Spongy body 1 is made by the composite polyvinyl alcohol porous material.
Be inserted with double channel catheter 2 in the described spongy body 1, evenly have some through holes on the duct wall that described double channel catheter 2 inserts in the spongy body 1.Be provided with flushing tract 21 and drain tract 22 in the described double channel catheter 2, have some flushing through holes on flushing tract 21 tube walls, have some drain through holes on drain tract 22 tube walls.As shown in Figure 2.
Described double channel catheter 2 outer ends connect drainage catheter 6 and irrigating catheter 4 by threeway 3.Described irrigating catheter 4 other ends are connected with joint 5, are connected with flushing device with convenient, realize washing capacity.Drainage catheter 6 other ends and negative pressure drainage equipment connection carry out negative pressure drainage.
Described threeway 3 is provided with two-chamber pore 34, flushing pore 32, drain pore 33, wherein is provided with a stainless steel tube 31 in the two-chamber pore 34, and it connects the flushing tract 21 of flushing pore 32 and double channel catheter 2.As shown in Figure 3.
Can be inserted with 1-3 double channel catheter in the described spongy body 1, each double channel catheter outer end connects a drainage catheter and an irrigating catheter by a threeway.For example, be inserted with two double channel catheteres in the described spongy body 1, each double channel catheter outer end connects a drainage catheter and an irrigating catheter by a threeway.Again for example, be inserted with three double channel catheteres in the described spongy body, each double channel catheter outer end connects a drainage catheter and an irrigating catheter by a threeway.
When this utility model uses, at first that patient's wound and wound surface cleaning is clean, select flushable negative pressure drainage dressing according to the size of wound surface, perhaps cutting and wound surface are complementary, and place on the wound surface of cleaning, cover with the transparent sticking film of biology, connect the HC negative pressure system or be connected to form drainage system with vacuum suction machine by drainage catheter 6, carry out drain, regulate the negative pressure of drainage system, observation drains the color of liquid and the state of spongy body 1, finds to have lump the shutdown system negative pressure to occur.By joint 5 and the irrigating catheter 4 flushing tract 21 interior injection physiological saline solution to double channel catheter 2, treat that spongy body 1 is softening with syringe, again open the drainage system switch, carry out drainage treatment.Drain and flushing can be carried out respectively, also drain and flushing can be carried out simultaneously.The medical sponge body can be washed in therapeutic process repeatedly, avoids in wound negative pressure treatment process spongy body to occur dry and stops up and cause the generation of the phenomenons such as inadequate drainage.Its structure rationally, and is easy for operation, reduced the number of times of changing dressings, and reduced the probability of clinical infection, the clinical manipulation safe ready.
