Description

Fluid collecting system of negative pressure wound therapeutic instrument capable of being poured in short time

Technical Field

The utility model belongs to negative pressure wound therapeutic instrument field especially relates to a fluid collecting system of negative pressure wound therapeutic instrument that can empty for the short time.

Background

Negative pressure wound therapy is an auxiliary treatment method for promoting wound healing, which is more and more popular in recent years, and the treatment method is characterized in that negative pressure is applied to the surface of a wound, so that the surface of the wound is uniformly subjected to the negative pressure to be reduced, the effect of draining body fluid is achieved, excessive exudates are removed, a relatively humid rather than humid environment is provided for wound closure, the edema of tissues around the wound is relieved, and the proliferation of granulation tissues is stimulated.

Currently, negative pressure wound therapy is widely used in clinical treatment of many acute/chronic wounds, including orthopedic, soft tissue, skin grafts, pressure sores, venous leg ulcers, diabetic feet, surgical infections, and post-operative wounds, among others. The physician will know whether the patient is suitable for negative pressure wound therapy according to the past disease history, current physiological status, medication status, autonomy and the like of the patient, and factors such as the size, depth, exudate quantity, infection and the like of the wound are evaluated.

The negative pressure wound therapeutic apparatus is necessary equipment for realizing negative pressure wound therapy, and comprises a negative pressure source, wherein the negative pressure source is connected with a fluid collecting system through a pipeline, the fluid collecting system is connected with a wound dressing system through a pipeline, and the wound dressing system is used for forming sealing on the surface of a wound. The wound exudate enters the fluid collection system through the pipeline under the suction action of the negative pressure source. Due to the fluidity of the exudate, when the fluid collection system is inadvertently dumped, the exudate can flow through the tubing to the negative pressure source, causing the negative pressure source to malfunction and fail.

When the patient needs to move, in order to prevent the exudate from entering the negative pressure source when the fluid collection system is toppled over, the negative pressure source needs to be cut off, the fluid collection system and the wound dressing system are disconnected, and only the wound dressing system is carried to move. During the patient's activity, the wound cannot be in a negative pressure state, and the exudate cannot be absorbed immediately, which may reduce the therapeutic effect.

Therefore, there is a need for a fluid collection system that can be dumped for a short period of time, so that a patient can carry the negative pressure wound therapy apparatus with him or her while exercising, and the therapeutic effect is improved.

Detailed Description

The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.

Examples are given. A fluid collecting system of a negative pressure wound therapy apparatus which can be poured in a short time, as shown in figure 1, comprises a drainage tank consisting of a front cover 1 and a back cover 2;

a first pipe joint 3 is arranged at the upper end of the rear cover 2, a V-shaped partition plate 4 is arranged in the rear cover 2, two ends of the partition plate 4 are fixed with a top plate of the rear cover 2, a sealing cover 5 is arranged on the front side of the partition plate 4, a small bin 6 communicated with the first pipe joint 3 is formed among the partition plate 4, the sealing cover 5 and the rear cover 2, and an air pipe 17 extending into the small bin 6 is arranged on the sealing cover 5;

the front side of protecgulum 1 is equipped with the eckerchief 18 that is used for placing negative pressure source 7, negative pressure source 7 is the suction pump, and the top of protecgulum 1 is equipped with gas pocket 8, and gas pocket 8 department is equipped with the second coupling 9 that is used for connecting negative pressure source 7, is equipped with water absorbing material 10 in the drainage jar, and water absorbing material 10 is located the bottom of drainage jar, and water absorbing material 10's top is equipped with drainage tube 11, and the rear end of drainage tube 11 inserts in little storehouse 6.

A water-blocking breathable film 12 is arranged in the air hole 8, and dehumidifying cotton 13 is arranged on the lower side of the water-blocking breathable film 12.

The drainage tube 11 is L-shaped, the front end of the drainage tube 11 is bent downwards, and the side wall of the drainage tube 11 is provided with a vent 14.

The water absorbing material 10 is super absorbent resin or ice crystal powder.

The first pipe joint 3 is positioned in the middle of the small chamber 6.

A U-shaped supporting plate 15 is arranged in the front cover 1, two ends of the supporting plate 15 are fixed with a top plate of the front cover 1, and the dehumidifying cotton 13 is located on the inner side of the supporting plate 15. The support plate 15 is used for fixing the dehumidifying cotton 13.

The drainage tank is internally provided with a horizontal plate 16, and the horizontal plate 16 is positioned below the partition plate 4. The two horizontal plates 16 are fixed to the front cover 1 and the rear cover 2, and a gap is left between the two horizontal plates 16. Draft tube 11 passes between two horizontal plates 16.

The utility model discloses an use: the negative pressure source 7 is placed in the bib, the suction port of the negative pressure source 7 is connected by tubing to the second tube connector 9, and the first tube connector 3 is connected by tubing to the wound dressing system. When the negative pressure type wound drainage device works, the negative pressure source 7 generates negative pressure, exudate of a wound enters the small bin 6 through the pipeline and the first pipe joint 3 under the action of the negative pressure, and when the liquid level of the exudate in the small bin exceeds the drainage pipe 11, the exudate flows out of the drainage pipe 11 and enters the lower part of the drainage tank to be absorbed by the water absorption material 10, so that the flowability of the exudate is greatly reduced. Moisture generated by the exudate leaves the small bin 6 through the air pipe 17, is absorbed by the dehumidifying cotton 13, and is ensured not to enter a negative pressure source through the water-blocking breathable film 12.

The air vent 14 has the function of balancing the internal and external pressure of the drainage tube 11 when the liquid level of the effusion at the bottom of the drainage tank is higher than the height of the lower end of the drainage tube 11, and preventing the effusion from being sucked back into the small bin 6. The air tube 17 is used to enable the negative pressure generated by the negative pressure source to be transmitted into the small chamber 6 and further to the wound dressing system.

When the fluid collecting system is toppled, the exudate at the bottom of the drainage tank is absorbed by the water absorbing material 10, so that the flowability is greatly reduced, and the horizontal plate 16 plays a certain role of isolating, so that the exudate is not easy to flow to the position near the second pipe joint 9 and then is not easy to enter the negative pressure source 7. The effusion in the small chamber 6 is obstructed by the air pipe 17, and can not directly leave the small chamber 6, and can not flow to the vicinity of the second pipe joint 9, and can not easily enter the negative pressure source 7. Moreover, even if the exudate flows to the vicinity of the second pipe joint 9, the water-blocking breathable film 12 can prevent the exudate from flowing out within a certain period of time, and further prevent the negative pressure source 7 from being damaged.

The utility model has the advantage of short-time dumping, so that the patient can carry the negative pressure wound therapeutic apparatus when moving, and the therapeutic effect is improved.
