Description

Technical Field

[0001] The utility model belongs to the field of medical instruments, and in particular relates to a disposable drainage sheet for superficial organ surgery. Background Art

[0002] In many cases, it is not necessary to place a drainage tube after superficial organ surgery. Instead, only a disposable drainage sheet is needed, which will be removed in a short period of time depending on the patient's condition. Surgeons often use the rolled edges of sterile gloves to make cigarette-shaped drainage sheets. This type of drainage sheet is characterized by a relatively soft material and decent patient comfort, but the drainage channel formed is easily blocked, and poor drainage often occurs. Surgeons sometimes use the plastic tube of a scalp needle to cut out a side hole and use it as a drainage sheet. This type of drainage sheet is characterized by a relatively hard material and poor patient comfort. Regardless of the type of drainage sheet, it needs to be sutured to fix it to the body surface in order to prevent it from slipping into the surgical wound. Utility Model Content

[0003] The utility model provides a disposable drainage sheet for superficial organ surgery, aiming to overcome the above-mentioned shortcomings of the prior art to at least a certain extent.

[0004] The utility model provides a technical solution to the above-mentioned technical problem as follows: a disposable drainage sheet for postoperative superficial organ surgery, comprising a long sheet-shaped drainage sheet one, a drainage sheet two and a drainage sheet three, the side edges of the drainage sheet one and the drainage sheet two being opposite to each other through two easy-to-tear connecting parts and then connected to each other to form a long tube body, the two easy-to-tear connecting parts extending axially on the long tube body and radially opposite to each other, the drainage sheet three being located in the inner cavity of the long tube body and the two side edges being fixedly connected to the two easy-to-tear connecting parts, an anti-slip-in protrusion and an anti-slip-out protrusion being provided on the outer wall of the middle tube section of the long tube body, the anti-slip-in protrusion and the anti-slip-out protrusion being spaced apart in the axial direction of the long tube body.

[0005] On the basis of the above technical solution, the present invention can also be improved as follows.

[0006] Furthermore, each of the easily tearable connection portions comprises two parallel and spaced-apart easily tearable lines, and the easily tearable connection portion is located in a narrow strip region between the two easily tearable lines and is fixedly connected to the side edge of the drainage piece three.

[0007] Furthermore, the tear line is broken between the anti-slip in protrusion and the anti-slip out protrusion, and the breaking length is 0.5-1.2 cm.

[0008] Furthermore, the easy-tear line is a perforated line or a half-cut line.

[0009] Furthermore, the drainage piece three is bent into an S shape in the radial direction of the long tube body.

[0010] Furthermore, the anti-slip protrusion is a circular ring piece fixed on the outer wall of the long tube.

[0011] Furthermore, the circular ring sheet is provided with at least a pair of radially opposite notches for suturing the wound below.

[0012] Furthermore, the anti-slip protrusion is composed of two hemispherical protrusions which are radially symmetrically arranged on both sides of the long tube body.

[0013] Furthermore, the drainage piece 1 and the drainage piece 2 are provided with a plurality of drainage grooves arranged along the axial direction on the side walls inside the long tube body.

[0014] Furthermore, the drainage sheet one, drainage sheet two and drainage sheet three are all made of medical flexible material, the medical flexible material is silicone or TPE, the thickness of drainage sheet one, drainage sheet two and drainage sheet are all 0.2-0.4mm, the total length of the long tube body is 8-12cm and the length of the tube section located subcutaneously when in use is 6-7cm, and the diameter of the long tube body is 0.3-0.5cm.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] The utility model provides a disposable drainage sheet for superficial organs after surgery, which is connected by a drainage sheet 1, a drainage sheet 2 and a drainage sheet 3 through an easy-tear connection part. When in use, it can be used in a plurality of forked shapes after one or both ends are torn, which can enhance the drainage effect and avoid blockage. It can also be used directly like a drainage tube without tearing both ends, and the drainage channel formed in the tube is not easy to be blocked. It has an anti-slip protrusion and an anti-slip protrusion, which cooperate to make the disposable drainage sheet better limited when it is used without suturing with the skin, avoid accidental slipping out or slipping in during use, and ensure a good drainage effect. The disposable drainage sheet is made of flexible material, and the patient feels better; the disposable drainage sheet only needs to be cut into an appropriate length when in use, which is more convenient and efficient than the current postoperative doctor cutting the sterile gloves on-site to make cigarette-shaped drainage sheets or using a harder scalp needle tube to cut out side holes to make harder drainage sheets. When the two ends are not torn along the easy-tear line, the disposable drainage sheet is soft and long tube-shaped as a whole, which is easy to package and store. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0025] In the description of the present invention, if terms indicating orientation such as "up", "down", "left", "right", "top", "bottom", "inside" and "outside" are used, the orientation or position relationship indicated is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0026] like Figures 1 to 5 As shown, the utility model provides a disposable drainage sheet for postoperative superficial organ surgery, which includes a long sheet-shaped drainage sheet 1, a drainage sheet 2 and a drainage sheet 3, the side edges of the drainage sheet 1 and the drainage sheet 2 are connected to each other through two easy-to-tear connecting parts in pairs to form a long tube body, the two easy-to-tear connecting parts extend axially on the long tube body and are radially opposite, the drainage sheet 3 3 is located in the inner cavity of the long tube body and the two side edges are fixedly connected to the two easy-to-tear connecting parts, and an anti-slip protrusion 4 and an anti-slip protrusion 5 are provided on the outer wall of the middle tube section of the long tube body, and the anti-slip protrusion 4 and the anti-slip protrusion 5 are spaced apart from each other in the axial direction of the long tube body.

[0027] It should be noted that drainage sheets one to three are preferably of equal length and are relatively soft. The long tube formed by connecting the three is softer than ordinary scalp needle tubes and slightly harder than the cigarette-shaped drainage sheets cut and rolled by doctors using sterile gloves. Therefore, it can ensure a better drainage effect without causing discomfort to the patient due to its own hardness.

[0028] In one embodiment of the present invention, Figures 1 to 3 As shown, each of the easy-tear connection parts includes two parallel and spaced easy-tear lines 6, and the easy-tear connection part is located in a narrow strip area between the two easy-tear lines 6 and is fixedly connected to the side of the drainage sheet 3 3. The easy-tear line 6 is preferably a perforated line or a half-cut line.

[0029] It is understandable that if the perforated line is torn, the cross section is generally relatively rough, but since each drainage sheet is made of flexible material, even a relatively rough cross section will not cause obvious damage to the patient's wound or increase pain when the drainage sheet is removed. The semi-cut tear line can ensure that the torn cross section is relatively smooth.

[0030] In one embodiment of the present invention, the tear line 6 is broken between the anti-slip-in protrusion 4 and the anti-slip-out protrusion 5 and the breaking length is 0.5-1.2 cm.

[0031] The anti-slip protrusion is mainly used to prevent the drainage sheet from sliding too much or completely into the wound, and the anti-slip protrusion is used to prevent the drainage sheet from sliding out prematurely before the removal conditions are met, resulting in drainage failure.

[0032] In one embodiment of the present invention, Figure 2 As shown, the guide piece 3 is bent into an S shape in the radial direction of the long tube body.

[0033] It should be noted that the drainage sheet with an S-shaped cross section can form drainage channels on both sides (especially when torn for use), which can ensure a better drainage effect.

[0034] In one embodiment of the present invention, Figure 1 As shown, the anti-slip protrusion 4 is a circular ring piece fixed on the outer wall of the long tube. In order to ensure that the wound can be effectively sutured after the drainage piece is placed in the wound, especially the suture of the wound near the drainage piece, at least a pair of notches 7 are provided on the circular ring piece in radially opposite directions to facilitate suturing the wound below.

[0035] It should be noted that the anti-slip protrusion is not limited to the circular sheet shape, and can also be set in a convex block shape as needed. In addition, in order to enhance the anti-slip and anti-slip effects, the anti-slip protrusion in the circular sheet shape can be provided with a self-adhesive layer with release paper on the side close to the skin, and the release paper is torn off during use, and the skin surface is adhered to the self-adhesive layer.

[0036] In one embodiment of the present invention, the anti-slip protrusion 5 is composed of two hemispherical protrusions radially symmetrically arranged on both sides of the long tube body.

[0037] In one embodiment of the present invention, the drainage piece 1 and the drainage piece 2 are provided on the side walls of the long tube body with a plurality of drainage grooves 8 arranged along the axial direction.

[0038] It is understandable that the drainage groove can be arranged not only on the inner wall of the drainage piece 1 and the drainage piece 2, but also on the drainage piece 3 or on the outer wall of the drainage piece 1 or the drainage piece 2 when necessary.

[0039] In one embodiment of the utility model, the drainage sheet 1, drainage sheet 2 and drainage sheet 3 are all made of medical flexible material, the medical flexible material is silicone or TPE, the thickness of the drainage sheet 1, drainage sheet 2 and drainage sheet are all 0.2-0.4mm, the total length of the long tube body is 8-12cm and the length of the tube section located under the skin when in use is 6-7cm, and the diameter of the long tube body is 0.3-0.5cm.

[0040] The disposable drainage sheet for superficial organ surgery provided by the utility model can be directly used as Figure 4 The drainage sheet is used in the manner shown in the figure. At this time, the upper and lower ends are not torn apart, and the drainage sheet 1, the drainage sheet 2 and the drainage sheet 3 are all connected together. The whole is similar to a very short drainage tube. The tube section located on the skin is generally shorter. After being flattened and attached to the skin, it is wrapped with gauze and adhered to the skin. The drained liquid flows out from the outer end of the long tube body and is absorbed by the wrapped gauze. The disposable drainage sheet for superficial organ surgery provided by the utility model can also be torn apart along the tear line at both ends and then placed on the incision for use, such as Figure 5 As shown, at this time, the drainage sheet is bifurcated into three drainage pieces both above and below the skin, with a wider drainage range. Moreover, after the skin part is torn open, each drainage piece is softer and easier to be bent against the skin and wrapped by gauze, and the effect of the drainage fluid being absorbed by the gauze is also higher.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
