Description

Technical Field

[0001] The utility model relates to the technical field of medical care products, in particular to a surgical drape with adjustable operation holes. Background Art

[0002] A surgical drape is a surgical sheet specifically used for performing surgical operations on specific parts of a patient. The surgical drape has holes opened for specific surgical locations, and the surgeon can perform the operation at this preset hole location.

[0003] Early surgical drapes were mainly made of cotton cloth. Due to the limitation of the physical properties of cotton cloth itself, it was difficult to combine other materials into one, and it could only be a simple drape. However, the complexity of modern surgical operations requires the use of new surgical drapes with various materials according to different functional needs, such as adhesive stickers, hot melt adhesives, drainage tubes, liquid collection bags, shaping strips, cast films, TPE elastic films, absorbent materials and label paper, etc. Therefore, traditional textiles have been difficult to adapt to modern surgical operations.

[0004] Therefore, at present, most of the conventional surgical drapes are made of non-woven fabrics, and holes of suitable sizes are pre-opened thereon. The inventor of this patent found in the course of work that for surgical drapes made of existing non-woven fabrics, the inner diameter of the holes opened is fixed during specific use. For some patients who need large incision surgery, the holes opened need to be temporarily cut to expand the corresponding inner diameter of the holes to adapt to the surgeon to pass through them to perform large incision surgery on the patients, which makes the operation troublesome and laborious.

[0005] In addition, the surgical drape made of existing non-woven fabric is thin and light. When it is laid on the surface of the patient's body, its periphery is not fixed and is easily blown by the breeze, which may affect the continuation of the patient's surgery.

[0006] In this regard, the inventor of this patent combined clinical experience, thought about the problems encountered in clinical work, read a large amount of scientific research materials and literature, and conducted retrieval and novelty searches to gradually conceive and design this application to solve related technical problems. Utility Model Content

[0009] In addition, the surgical drape with adjustable operation hole size according to the above embodiment of the utility model may also have the following additional technical features:

[0010] According to an embodiment of the utility model, a plurality of counterweight blocks are evenly arranged around the periphery of the upper end surface of the drape body, and each of the counterweight blocks includes a metal block located in an inner layer and a soft rubber block covering the outside of the metal block.

[0011] According to an embodiment of the utility model, a plurality of tightening ropes are evenly connected to the periphery of the drape body, and the plurality of tightening ropes are correspondingly located beside the plurality of counterweight blocks.

[0012] According to one embodiment of the utility model, a circular plastic adhesive sheet suitable for adhering to the skin around the surgical wound of the patient is fixedly provided on the lower end surface of the drape body, and the circular plastic adhesive sheet is wrapped around the outermost tearable circle.

[0013] According to one embodiment of the utility model, the annular plastic adhesive sheet has a certain layer thickness and is made of butene copolymer, gelatin, polypropylene glycol and ethylene-vinyl acetate copolymer, and a tear film is provided on the bottom surface of the annular plastic adhesive sheet, and a tear tab is provided on the periphery of the tear film.

[0014] According to one embodiment of the utility model, the hole towel body comprises a lower waterproof layer, a middle liquid-absorbing cotton ring and an upper waterproof layer;

[0015] The upper end surface of the lower waterproof layer is provided with an annular groove around its middle and downwardly close to its periphery; the middle liquid-absorbent cotton ring is fixed in the annular groove with an interference fit; the upper waterproof layer is stacked on the upper end surface of the middle liquid-absorbent cotton ring, and its outer diameter is smaller than the outer diameter of the middle liquid-absorbent cotton ring, so that the peripheral edge of the upper end surface of the middle liquid-absorbent cotton ring is exposed to form a liquid absorption area.

[0016] According to one embodiment of the utility model, the hood body further includes a heat preservation layer;

[0017] The thermal insulation layer is adhered to the lower bottom surface of the lower waterproof layer, and the middle part of the thermal insulation layer is hollowed out, and the annular plastic adhesive sheet is adhered to the lower bottom surface of the thermal insulation layer.

[0018] According to an embodiment of the utility model, the operation opening is opened in the middle of the lower waterproof layer, the middle of the upper waterproof layer and the middle of the thermal insulation layer, and a plurality of easy-tear rings are provided.

[0019] The beneficial effects of the utility model are:

[0020] First, in the specific implementation of the surgical drape with adjustable operation hole size provided by the present application, since a plurality of easy-tear circles are evenly arranged from the inside to the outside on the periphery of the surgical operation hole, a plurality of easy-tear openings are evenly spaced between each two adjacent easy-tear circles, and a plurality of easy-tear openings are also evenly spaced between the outermost easy-tear circle and the drape body, each of the easy-tear circles can be easily torn off, so that the size of the surgical operation hole can be quickly adjusted, eliminating the need for temporary cutting with medical scissors, so that the present application is time-saving, convenient and flexible in actual use.

[0021] Second, by evenly arranging a plurality of the counterweight blocks on the periphery of the upper end surface of the drape body, when the present application is actually used and laid on the patient, the plurality of the counterweight blocks will droop due to their own gravity, so that the periphery of the drape body can be better pressed to prevent the periphery from being blown up by the breeze and affecting the continuation of the patient's surgery. Since each of the counterweight blocks includes a metal block located in the inner layer and a soft rubber block covering the outside of the metal block, each of the counterweight blocks not only has a counterweight function, but also has a good soft appearance. When it touches the patient's body, it is not easy to hurt the patient's body, so that the present application is safe to use.

[0022] Third, since the lower end surface of the drape body is fixed with a circular plastic adhesive sheet suitable for being adhered to the skin around the surgical wound of the patient, the circular plastic adhesive sheet is wrapped outside the outermost easy-tear circle. Therefore, the circular plastic adhesive sheet is adhered to the skin around the surgical incision of the patient's body. Even if the skin around the surgical incision of the patient's body is uneven, after slightly pressing the circular plastic patch, it will automatically shape to automatically fill the uneven part of the skin around the surgical incision of the patient's body. In this way, it can be better adhered to the skin around the surgical incision of the patient's body together with the drape body, so that the fixing effect of the drape body is better and the adaptability to use is stronger.

[0023] Fourthly, when bleeding occurs at the surgical incision site of the patient's body, the bleeding will flow out along the upper end surface of the drape body, and when it flows to the liquid absorption area of ​​the liquid-absorbing cotton ring exposed at the annular groove, it will be quickly absorbed by the liquid-absorbing cotton ring. In this way, it can effectively prevent the bleeding from the surgical incision site of the patient's body from continuing to flow out, thereby dirtying the operating table or causing blood cross-infection among medical staff.

[0024] Additional aspects and advantages of the present invention will be given in part in the following description, and in part will become apparent from the following description, or will be learned through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0056] The following describes in detail a surgical drape 1000 with adjustable operation hole size according to an embodiment of the utility model with reference to the accompanying drawings.

[0057] Reference Figures 1 to 5 As shown, a surgical drape 1000 with an adjustable operation hole size provided according to an embodiment of the utility model comprises a drape body 10; a surgical operation opening 101 is opened in the middle of the drape body 10, and a plurality of easy-tear circles 102 are evenly arranged around the periphery of the surgical operation opening 101 from the inside to the outside, a plurality of easy-tear openings 103 are evenly spaced between each adjacent two easy-tear circles 102, and a plurality of easy-tear openings 103 are also evenly spaced between the outermost easy-tear circle 102 and the drape body 10.

[0058] Based on the above, it is clear that when the present application is implemented, it is mainly used as a surgical drape 1000 with an adjustable operating hole size.

[0059] Specifically, when applying the present application, medical staff tear off the tear-away ring 102 at the fitting position from the inside out by hand according to the size of the surgical incision on the patient's body. In this way, the inner diameter of the surgical operation port 101 can be adjusted to fit the surgical incision required for the use of the present application.

[0060] Regarding the use of the above-mentioned present application, it is obvious that since a plurality of easy-tear circles 102 are evenly arranged on the periphery of the surgical operation port 101 from the inside to the outside, a plurality of easy-tear openings 103 are evenly spaced apart between each two adjacent easy-tear circles 102, and a plurality of easy-tear openings 103 are also evenly spaced apart between the outermost easy-tear circle 102 and the drape body 10, each of the easy-tear circles 102 can be easily torn off, so that the size of the surgical operation port 101 can be quickly adjusted, eliminating the need to use medical scissors for temporary cutting, so that the present application is time-saving, convenient and flexible to use when actually used.

[0061] Furthermore, through the above-mentioned optimized design, the overall structure of the present application is highly practical and has good use effect.

[0062] Furthermore, in the specific implementation, Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, according to one embodiment of the utility model, a plurality of counterweight blocks 20 are evenly arranged around the periphery of the upper end surface of the drape body 10 , and each of the counterweight blocks 20 includes a metal block 201 located in an inner layer and a soft rubber block 202 coated outside the metal block 201 .

[0063] Thus, it can be clearly seen that, on the one hand, by evenly arranging a plurality of the counterweight blocks 20 on the periphery of the upper end surface of the drape body 10, when the present application is actually used and the present application is laid on the patient, the plurality of the counterweight blocks 20 arranged will droop due to their own gravity, so that the periphery of the drape body 10 can be better pressed to prevent the periphery from being blown up by the breeze and affecting the continuation of the patient's surgery. On the other hand, since each of the counterweight blocks 20 includes a metal block 201 located in the inner layer and a soft rubber block 202 covering the outside of the metal block 201, each of the counterweight blocks 20 not only has a counterweight function, but also has a good soft appearance. When it touches the patient's body, it is not easy to hurt the patient's body, so that the present application is safe to use.

[0064] Furthermore, through the above-mentioned optimization design, the overall use effect of the present application can be effectively improved.

[0065] Furthermore, in the specific implementation, Figure 1 , Figure 2 and Figure 5 As shown, according to one embodiment of the present invention, a plurality of tie ropes 30 are evenly connected to the periphery of the drape body 10 , and the plurality of tie ropes 30 are correspondingly located beside the plurality of counterweight blocks 20 .

[0066] In this regard, it is clear that when the present application is actually used, when necessary, multiple tie ropes 30 can be used to tie the periphery of the drape body 10 to the edge of the operating bed, so that the fixing effect of the present application is better during specific use.

[0067] Furthermore, in this technical solution, Figure 3 and Figure 4 As shown, according to one embodiment of the utility model, a circular plastic adhesive sheet 40 suitable for adhering to the skin around the surgical wound of the patient is fixedly provided on the lower end surface of the drape body 10, and the circular plastic adhesive sheet 40 is wrapped outside the outermost tear circle 102.

[0068] Preferably, in the present technical scheme, according to an embodiment of the present utility model, the annular plastic adhesive sheet 40 has a certain layer thickness, and its layer thickness is preferably set to 0.5 cm, and is made of butene copolymer, gelatin, polypropylene glycol and ethylene-vinyl acetate copolymer, and a layer of tear film 50 is provided on the bottom surface of the annular plastic adhesive sheet 40, and a tear tab 501 is provided on the periphery of the tear film 50.

[0069] In this regard, it can be understood that after tearing off the tear film 50 through the tear tab 501 and adhering the annular plastic adhesive sheet 40 to the skin around the surgical incision site of the patient's body, even if the skin around the surgical incision site of the patient's body is uneven, after slightly pressing the annular plastic patch, it will automatically shape so as to automatically fill the uneven area of ​​the skin around the surgical incision site of the patient's body. In this way, it can be better adhered to the skin around the surgical incision site of the patient's body together with the drape body 10, so that the fixing effect of the drape body 10 is better and the adaptability to use is stronger.

[0070] At the same time, after the drape body 10 is adhered to the skin around the surgical incision site on the patient's body, it is not easy for bleeding to overflow from the surgical incision site on the patient's body and flow around along the bottom surface of the drape body 10 or flow around along the skin around the surgical incision site on the patient's body to dirty the operating table or cause blood cross infection to medical staff, making the application safe to use.

[0071] In addition, during the specific implementation, continue to compare Figure 3 and Figure 4 As shown, according to one embodiment of the utility model, the drape body 10 includes a lower waterproof layer 10a, a middle liquid-absorbing cotton ring 10b and an upper waterproof layer 10c;

[0072] Among them, the upper end surface of the lower waterproof layer 10a is opened with an annular groove 10a1 around its middle and close to its periphery; the middle liquid-absorbent cotton ring 10b is fixed in the annular groove 10a1 with an interference fit; the upper waterproof layer 10c is stacked on the upper end surface of the middle liquid-absorbent cotton ring 10b, and its outer diameter is smaller than the outer diameter of the middle liquid-absorbent cotton ring 10b, so that the peripheral edge of the upper end surface of the middle liquid-absorbent cotton ring 10b is exposed to form a liquid absorption area 10b1.

[0073] In this regard, it is clear that when the present application is actually used, when bleeding occurs at the surgical incision site on the patient's body, the bleeding will flow out along the upper end surface of the drape body 10, and when it flows to the absorbent area 10b1 of the absorbent cotton ring exposed at the annular groove 10a1, it will be quickly absorbed by the absorbent cotton ring. In this way, it is possible to effectively prevent the bleeding from the surgical incision site on the patient's body from continuing to flow out and dirty the operating table or cause blood cross infection among medical staff.

[0074] Furthermore, through the above-mentioned optimization design, the overall use effect of the present application can be further improved.

[0075] Preferably, in the present technical solution, the lower waterproof layer 10a and the upper waterproof layer 10c are both made of waterproof non-woven fabric.

[0076] Furthermore, in this technical solution, Figure 3 and Figure 4 As shown, according to one embodiment of the present invention, the hood body 10 further includes a heat preservation layer 10d;

[0077] The thermal insulation layer 10d is bonded to the lower bottom surface of the lower waterproof layer 10a, and the middle of the thermal insulation layer 10d is hollowed out and is preferably made of cotton material. The annular plastic adhesive sheet 40 is bonded to the lower bottom surface of the thermal insulation layer 10d.

[0078] Therefore, it should be noted that when a patient undergoes surgical operation, the part of his body that needs surgery needs to be exposed to a large extent, that is, no clothes are worn. At this time, after using the present application, the thermal insulation layer 10d is attached to the surface of the patient's skin, so that the exposed part of the patient's skin can be kept warm, so that the patient feels comfortable.

[0079] On this basis, in the present technical solution, according to an embodiment of the present utility model, the operation opening is opened in the middle of the lower waterproof layer 10a, the middle of the upper waterproof layer 10c and the middle of the thermal insulation layer 10d, and a plurality of the tearable rings 102 are provided.

[0080] It should be added that, in a specific implementation, according to an embodiment of the present invention, the width of each of the easy-tear rings 102 is set to 1.0 cm, and the easy-tear rings 102 are provided with at least 4 rings.

[0081] Other embodiments and the like are not described here by way of example.

[0082] In summary, the surgical drape 1000 with adjustable operation hole size provided by the present application, in specific implementation, since a plurality of easy-tear circles 102 are evenly arranged on the periphery of the surgical operation port 101 from the inside to the outside, a plurality of easy-tear openings 103 are evenly spaced between each two adjacent easy-tear circles 102, and a plurality of easy-tear openings 103 are also evenly spaced between the outermost easy-tear circle 102 and the drape body 10, each of the easy-tear circles 102 can be easily torn off, so that the size of the surgical operation port 101 can be quickly adjusted, eliminating the need to use medical scissors for temporary cutting, so that the present application is time-saving, convenient and flexible to use when actually used.

[0083] Furthermore, by evenly arranging a plurality of the counterweight blocks 20 on the periphery of the upper end surface of the drape body 10, when the present invention is actually used and laid on the patient, the plurality of the counterweight blocks 20 will droop due to their own gravity, so that the periphery of the drape body 10 can be better pressed to prevent the periphery from being blown up by the breeze and affecting the continuation of the patient's surgery. Since each of the counterweight blocks 20 includes a metal block 201 located in the inner layer and a soft rubber block 202 covering the outside of the metal block 201, each of the counterweight blocks 20 not only has a counterweight function, but also has a good soft appearance. When it touches the patient's body, it is not easy to hurt the patient's body, so that the present invention is safe to use.

[0084] In addition, since the lower end surface of the drape body 10 is fixed with a circular plastic adhesive sheet 40 suitable for being adhered to the skin around the surgical wound of the patient, the circular plastic adhesive sheet 40 is wrapped outside the outermost easy-tear circle 102. Therefore, the circular plastic adhesive sheet 40 is adhered to the skin around the surgical incision of the patient's body, even if the skin around the surgical incision of the patient's body is uneven, after slightly pressing the circular plastic patch, it will automatically shape to automatically fill the uneven part of the skin around the surgical incision of the patient's body. In this way, it can be better adhered to the skin around the surgical incision of the patient's body together with the drape body 10, so that the drape body 10 has a better fixing effect and stronger adaptability.

[0085] At the same time, when bleeding occurs at the surgical incision site on the patient's body, the bleeding will flow out along the upper end surface of the drape body 10, and when it flows to the absorbent area 10b1 of the absorbent cotton ring exposed at the annular groove 10a1, it will be quickly absorbed by the absorbent cotton ring. In this way, it can effectively prevent the bleeding from the surgical incision site on the patient's body from continuing to flow out and dirty the operating table or cause blood cross infection among medical staff.

[0086] Furthermore, the surgical drape 1000 with adjustable operating hole size provided by the present application is indeed extremely practical and has excellent use effect, which makes the present application bound to have a good market promotion value, and the present application is bound to be very popular and will be effectively popularized.
