Abstract
The utility model relates to a disposable continuous negative pressure aspirator with low cost and good usage effect, which comprises an injector body and a piston rod, wherein the injector body is connected with the piston rod in a relative slide mode, and volume markings are arranged on the injector body. The disposable continuous negative pressure aspirator is characterized in that a silica gel drainage tube is in sealing connection with an injection end of the injector body, side holes are arranged at a free end of the silica gel drainage tube, a sealing plug is arranged at a connecting end of the silica gel drainage tube, fixing holes are arranged on the piston rod, and fixing rods are arranged in the fixing holes.
Description
Technical field
This utility model relates to a kind of medical supplies, relates in particular to a kind of Dispensable continuous negative-pressure suction pump.
Background technology
Utilize at present that negative-pressure sealed drainage technology VSD technology treatment III, IV phase pressure ulcer are clinical to have obtained sure effect.Because the VSD device costs an arm and a leg about 3000 yuan, must connect central negative pressure and attract, the patient is mobile restricted.The noise of vacuum suction has also had a strong impact on patient's sleep.The drain caliber is thicker, and under the high negative pressure state, pipeline is inhaled flat easily, causes attraction obstructed.The pipeline that relates to is more, is unfavorable for the pipeline nursing, stands up also to be restricted, and cost is high, and result of use is poor.
Summary of the invention
The purpose of this utility model provides the Dispensable continuous negative-pressure suction pump that a kind of cost is low, result of use is good.
For realizing above-mentioned purpose; The technical scheme that this utility model adopts is: a kind of Dispensable continuous negative-pressure suction pump, comprise syringe body and piston rod, and syringe body and piston rod are slidingly connected relatively; Syringe body is marked with the capacity sign; It is characterized in that: the dispensing end of described syringe body is sealedly connected with the silica gel drainage tube, and the free end of silica gel drainage tube has side opening, and the link of silica gel drainage tube is designed with sealing-plug; Be designed with fixing hole on the described piston rod, be inserted with fixed bar in the fixing hole.
In this structure, also indicate the pressure sign on the syringe body.
The utility model has the advantages of and be: because the dispensing end of syringe body is sealedly connected with the silica gel drainage tube in this utility model; The free end of silica gel drainage tube has side opening; The link of silica gel drainage tube is designed with sealing-plug, is designed with fixing hole on the piston rod, is inserted with fixed bar in the fixing hole; So use this utility model cost low, result of use is good.
Description of drawings
Fig. 1 is the structural representation of this utility model.
In the accompanying drawing: 1, capacity sign; 2, pressure sign; 3, syringe body; 4, piston rod; 5, fixing hole; 6, fixed bar; 7, sealing-plug; 8, side opening; 9, silica gel drainage tube.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment this utility model is described further:
This utility model is as shown in Figure 1; A kind of Dispensable continuous negative-pressure suction pump comprises syringe body 3 and piston rod 4, and syringe body 3 is slidingly connected with piston rod 4 relatively; Syringe body 3 is marked with capacity sign 1; It is characterized in that: the dispensing end of described syringe body 3 is sealedly connected with silica gel drainage tube 9, and the free end of silica gel drainage tube 9 has side opening 8, and the link of silica gel drainage tube 9 is designed with sealing-plug 7; Be designed with fixing hole 5 on the described piston rod 4, be inserted with fixed bar 6 in the fixing hole 5; In the present embodiment, also indicate pressure sign 2 on the syringe body 3.
After pressure ulcer wound surface flushing is changed dressings, the free end of silica gel drainage tube is placed on the wound surface place, utilizing applies ointment or plaster fills and covers, and the reuse transparent dressing is airtight fully with whole wound; According to wound size, utilize fixed bar to insert in the fixing hole, the seized piston bar makes it not bounce back, and forms the negative pressure drainage device of a sealed, sterile like this, can keep in the wound surface, negative pressure state in drainage tube and the syringe; Fix according to position, prevent the pressurized drainage system; The fully drain of applying ointment or plaster can keep the uniform negative pressure in wound surface center again, and adsorptivity is strong, and can adhere to a large amount of sloughs, and more change dressings can be removed these sloughs easily, avoids the residual of secretions.The tissue fluid that utilizes this utility model to draw can be done microorganism culturing, injects the choose reasonable antibiotic according to cultivation results to wound surface, and disposable use, and disinfection and isolation is convenient, and is cheap, easy and simple to handle, is fit to use at home.
