Abstract
Description
Technical Field
[0001] This application relates to the technical field of wound care medical devices, and particularly to a wound secretion drainage bag. Background Art
[0002] Wound ulceration refers to an open wound that occurs on the body surface or deep within tissues, usually accompanied by tissue damage, ulceration, and inflammation. This condition can be caused by a variety of factors, including trauma, surgery, infection, blood circulation problems, or chronic diseases. For example, patients with advanced tumors often face multiple health problems, one of which is advanced wound ulceration. This may be due to ulceration caused by the primary tumor or due to side effects of cancer treatment, such as radiotherapy or chemotherapy, which lead to tissue damage.
[0003] Many patients with wound ulceration have excessive exudate. Clinically, the frequency of dressing changes is usually increased to prevent the exudate from flowing out, but this increases the workload of medical staff, and repeated dressing changes also increase the pain of the patient; or the amount of dressing is increased to absorb more exudate and reduce the frequency of dressing changes, but fixing too many dressings for bandaging will cause discomfort to the patient. Utility Model Content

[0026] In addition, the technical features involved in the different embodiments of the present invention described above can be combined with each other as long as they do not conflict with each other.
[0027] The present invention provides as Figures 1 to 2As shown in the figure, a wound secretion drainage bag aims to solve the problem that the exudate of patients with wound ulceration cannot be removed in time.
[0028] This wound secretion drainage bag mainly includes a chassis 100 and a collector 200. The chassis 100 is used to collect the wound secretions of patients, and the collector 200 is used to store the wound secretions of patients collected by the chassis 100. The chassis 100 and the collector 200 are detachably connected. When there is too much wound secretion of patients in the collector 200, the collector 200 can be replaced to continue storing the wound secretions of patients collected by the chassis 100, reducing the frequency of dressing changes.
[0029] The chassis 100 includes an adsorption part 101, a drainage channel 102 and a disc part 103. The drainage channel 102 has opposite proximal and distal ends. For the convenience of description, the end of the drainage channel 102 close to the medical staff is called the proximal end, and the end of the drainage channel 102 close to the patient is called the distal end. The drainage channel 102 is arranged on the adsorption part 101, and the adsorption part 101 is used to adsorb on the skin of the patient, so that the opening at the distal end tightly adsorbs on the skin of the patient to collect the wound secretions of the patient.
[0030] The disc part 103 is fitted in the opening at the distal end. The opening at the distal end covers the patient's wound and is used to collect the wound secretions of the patient. There is an opening in the middle of the disc part 103, and the patient's wound is arranged in the opening of the disc part 103. Preferably, the disc part 103 can be cut, that is to say, the opening of the disc part 103 can be enlarged as needed to match the size of the wound. When the wound secretion of the patient flows out, it first flows to the disc part 103 under the action of gravity, and then moves along the drainage channel 102.
[0031] The collector 200 is detachably connected to the proximal end. The collector 200 can be replaced to continue storing the wound secretions of patients collected by the chassis 100, reducing the frequency of dressing changes. There is a receiving cavity 201 in the collector 200, and the receiving cavity 201 is communicated with the drainage channel 102. The receiving cavity 201 is used to store the wound secretions of patients collected by the chassis 100.
[0032] Many patients with wound ulceration have too much exudate. Clinically, the frequency of dressing changes is usually increased to prevent the exudate from flowing out, but this increases the workload of medical staff, and repeated dressing changes also increase the pain of patients; or the amount of dressing is increased to adsorb more exudate to reduce the frequency of dressing changes, but fixing too many dressings will cause discomfort to patients.
[0033] The utility model adsorbs on the skin of a patient through a chassis 100 provided with an adsorption part 101. The distal opening of a drainage channel 102 covers the patient's wound. The wound secretion of the patient flows into the drainage channel 102 and is stored in a containing cavity 201, without the need to use dressings to adsorb exudate, reducing the discomfort of the patient. Moreover, the collector 200 is detachably connected to the chassis 100. When there is too much wound secretion in the containing cavity 201, only a new collector 200 needs to be replaced, greatly reducing the frequency of dressing changes and the workload of medical staff.
[0034] In some embodiments, as Figures 1 to 2 shown in [reference], the adsorption part 101 is arranged in a circle around the circumferential direction of the distal opening. A paste layer is arranged on the surface of the adsorption part 101 opposite to the skin of the patient. Preferably, the paste layer is an adhesive layer and can be pasted on the skin of the patient.
[0035] In some embodiments, the adsorption part 101 is a hydrocolloid dressing, which is suitable for wound care, can also absorb exudate, and prevent the wound secretion of the patient from flowing out.
[0036] In some embodiments, as Figures 1 to 2 shown in [reference], the inner diameter of the distal end gradually becomes smaller towards the proximal end to form a funnel-shaped funnel part 1021, so as to facilitate the collection of the patient's wound secretion. Preferably, the outer surface of the funnel part 1021 is made of a plastic film.
[0037] In some embodiments, as Figures 1 to 2 shown in [reference], a cutting guide area 1031 is arranged on a disc part 103. The cutting guide area 1031 includes a plurality of circular guide lines with different radii, and all the plurality of circular guide lines are concentrically arranged with the opening of the disc part 103. During actual use, the opening of the disc part 103 can be cut and enlarged as needed to match the size of the wound. When the patient's wound secretion flows out, it first flows to the disc part 103 under the action of gravity, and then moves along the drainage channel 102.
[0038] In some embodiments, as Figures 1 to 2 shown in [reference], the wound secretion drainage bag further includes: a valve 301, which is arranged on the drainage channel 102 and is used to control the on-off between the proximal end and the distal end. During actual use, when there is too much wound secretion of the patient in the collector 200, the proximal end and the distal end can be blocked by controlling the valve 301 first, then a new collector 200 is replaced, and then the proximal end and the distal end are connected by controlling the valve 301, so that the new collector 200 continues to store the patient's wound secretion collected by the chassis 100, and the patient's wound secretion can be continuously collected without removing the chassis 100, reducing the frequency of dressing changes.
[0039] In some embodiments, as Figures 1 to 2As shown in [figure], the collector 200 further includes: a drainage ball 202, which is detachably connected to the proximal end. The negative pressure drainage ball 202 is made of medical-grade silicone material and mainly consists of a drainage tube, a diaphragm joint, a catheter, a balloon, a drainage plug, and a negative pressure ball. It is currently widely used for clinical negative pressure drainage and storage of drainage fluid, and can provide a negative pressure environment for the drainage channel 102 of this device to guide the patient's wound secretions into the drainage channel 102.
[0040] In some embodiments, such as Figures 1 to 2 As shown in [figure], the collector 200 further includes: a negative pressure tube 203. One end of the negative pressure tube 203 is connected to the drainage ball 202, and the other end of the negative pressure tube 203 is disposed within the drainage channel 102. The drainage ball 202 is detachably connected to the proximal end through the negative pressure tube 203. During actual use, the outer surface of the accommodation cavity 201 is made of a material with a relatively high hardness, such as plastic. The volume of the accommodation cavity 201 can be regarded as unchanged. At this time, the drainage ball 202 provides negative pressure for the drainage channel 102 through the negative pressure tube 203 to guide the patient's wound secretions into the drainage channel 102, causing the patient's wound secretions to flow into the accommodation cavity 201. When the negative pressure tube 203 is not in contact with the patient's wound secretions, the patient's wound secretions will not enter the drainage ball 202. At this time, the drainage ball 202 only serves as a structure for providing negative pressure. When there is too much patient's wound secretions in the collector 200, there is no need to replace the drainage ball 202. Only the collector 200 needs to be replaced to continue storing the patient's wound secretions collected by the chassis 100, reducing the frequency of dressing changes.
[0041] In some embodiments, such as Figure 2 As shown in [figure], the drainage channel 102 further includes: a gas-liquid separation part 1022. The gas-liquid separation part 1022 includes an inclined channel that slopes upward horizontally towards the proximal end. During actual use, a negative pressure environment is formed within the drainage channel 102. When the patient's wound secretions flow into the drainage channel 102, they move at the bottom of the inclined channel under the action of gravity. One end of the negative pressure tube 203 penetrates above the inclined channel and is connected to the inclined channel. The negative pressure tube 203 is not in contact with the patient's wound secretions, and the patient's wound secretions will not enter the drainage ball 202. At this time, the drainage ball 202 only serves as a structure for providing negative pressure. When there is too much patient's wound secretions in the collector 200, there is no need to replace the drainage ball 202. Only the collector 200 needs to be replaced to continue storing the patient's wound secretions collected by the chassis 100, reducing the frequency of dressing changes.
[0042] In some embodiments, such as Figures 1 to 2 As shown in [figure], the wound secretion drainage bag further includes: a fixing strap 401. The collector 200 is disposed on the fixing strap 401, and the fixing strap 401 is used to fix on the patient's limb to prevent the collector 200 from being too heavy and pulling the chassis 100 to cause the chassis 100 to fall off.
[0043] In summary, a wound secretion drainage bag is provided, which includes a chassis and a collector. The chassis includes an adsorption part, a drainage channel, and a disc part. The adsorption part is used to adsorb on the patient's skin. The opening at the distal end of the drainage channel covers the patient's wound. The disc part is correspondingly arranged in the opening at the distal end of the drainage channel. The collector is detachably connected to the proximal end. A receiving cavity communicating with the drainage channel is arranged in the collector. By providing the chassis and using the adsorption part to adsorb on the patient's skin, the opening at the distal end of the drainage channel covers the patient's wound, and the wound secretion of the patient flows into the drainage channel and is stored in the receiving cavity. There is no need to use dressings to adsorb exudate, reducing the discomfort of the patient. Moreover, the collector is detachably connected to the chassis. When there is too much wound secretion in the receiving cavity, only a new collector needs to be replaced, greatly reducing the frequency of dressing changes and the workload of medical staff.
[0044] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the present invention.
