Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices and relates to a sterile pad, in particular to a combined sterile pad which combines a compression cuff and a pad into one. Background Art

[0002] A drape is a common medical device used during blood collection. When used, it is placed under the patient's arm. During blood collection, not only is a drape necessary, but a cuff, cotton swabs, and other items are also required. First, the drape is placed, then the patient places their arm on the drape, and the cuff is fastened to their arm before blood is drawn. However, in daily blood collection, cuffs are often reused, while cotton swabs, drapes, and other items are typically disposable. Therefore, medical personnel need to separately retrieve the drape and cuff, which is cumbersome and can easily lead to forgetting to remove certain items. To address this issue, the drape, cuff, and other items are integrated into a single-use, disposable drape. This makes it more convenient for medical personnel to retrieve and prevents them from forgetting to remove certain items, thereby improving blood collection efficiency.

[0003] To this end, the utility model patent application number 201621126806.6 discloses a blood drawing pad that can prevent direct contact between the skin and the cuff. The pad includes a pad body, a first binding strap, and a second binding strap. The first binding strap and the second binding strap are respectively arranged on either side of the pad body, and the first binding strap, the second binding strap, and the pad body are integrally formed into a cross-shaped structure. When a doctor draws blood from a patient, the patient first places their arm on the pad body to keep the patient's arm in a relatively hygienic environment. The doctor then wraps the first and second binding straps around the patient's arm and tightens the cuff around the wrapped first and second binding straps to isolate the cuff from the patient's skin, thereby making it less likely for the patient to be infected with a disease or cause cross infection.

[0004] The utility model patent with application number 202120385117.1 discloses a disposable blood collection pad, which includes a pad main body and a tourniquet; the pad main body and the tourniquet are connected by a connecting part; one end of the pad main body and one end of the tourniquet are respectively fixedly connected with a bristle-surface Velcro; the pad main body and the tourniquet both include a first cotton layer, a PE film layer and a second cotton layer fixedly connected from top to bottom in sequence; the bristle-surface Velcro can be folded and opened; two elastic bags are fixedly connected to the first cotton layer of the pad main body; elastic ropes are provided on both sides of the tourniquet perpendicular to the extension direction of the tourniquet to keep the tourniquet in an uneven state. By providing a tourniquet and elastic ropes on both sides of the tourniquet for keeping the tourniquet in an uneven state, and fixing a bristle-surface Velcro on one end of the tourniquet, the tourniquet can replace the existing compression cuff, thereby improving the comfort of the human body to a certain extent and avoiding the problem of the existing compression cuff requiring disinfection after use; the pad main body and the tourniquet both include a first cotton layer, a PE film layer and a second cotton layer fixedly connected from top to bottom, which not only improves the comfort of the human body but also avoids contamination caused by bleeding from the needle hole during blood collection; two elastic bags are fixedly connected to the first cotton layer of the pad main body, one of which is used to place blood collection tubes, cotton swabs and other items before blood collection, and the other elastic bag is used to place blood collection tubes after blood collection, which greatly facilitates the blood collection work of nurses and avoids or reduces the risk of blood collection tubes falling, missing blood and causing contamination.

[0005] The first utility model relates to a blood-drawing drape, in which a bandage is wrapped around the patient's arm and a tourniquet is tightened around the bandage to isolate the tourniquet from the patient's skin. In the second utility model, a connecting portion connects the pad body to the tourniquet along the width of the pad body, so that the tourniquet can be detachably connected to the tourniquet by folding the bristle-surface Velcro 4 thereon. However, although neither of the two utility models involves an integrated connection between the tourniquet and the drape, the integrated connection between the bandage, tourniquet, and drape provides a reference for an integrated connection between the drape and drape. However, the ends of the bandage and tourniquet are separated from the pad body, making it inconvenient to store and take out. Utility Model Content

[0006] The purpose of the utility model is to provide a combined sterile pad in order to solve the technical problem in the prior art that the pad and the cuff are not integrally connected and the blood collection efficiency is low.

[0007] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0008] A combined sterile drape comprises a drape body, a compression cuff connected to the top of the drape body, the compression cuff being arranged along the width direction of the drape body, the drape body and the compression cuff being connected by a connecting portion in the middle and tear lines on both sides of the connecting portion;

[0009] One side of the pad main body is connected with a pressure sticker via an easy-tear line, and the pressure sticker is arranged along the length direction of the pad main body.

[0010] Furthermore, two easy-tear lines are provided on each side between the pad main body and the compression cuff, and a tear strip is formed between the two easy-tear lines on the same side.

[0011] Furthermore, one end of the tear strip close to the connecting portion is a cylindrical surface, and a gap is left between the cylindrical surface and the connecting portion.

[0012] Furthermore, the compression cuff is an elastic band.

[0013] Furthermore, the pressure patch includes a patch body, a drug layer arranged at the bottom of the patch body, and an adhesive layer arranged at the bottom of the patch body and located on both sides of the drug layer; an airbag is arranged in the middle area of the patch body, and air storage bags are arranged on both sides of the airbag in the patch body, and the air storage bags are connected to the airbag through an airway.

[0014] Furthermore, a sealing line formed by heat-pressing sealing is provided in the middle of the air channel.

[0015] The beneficial effects of the utility model are as follows:

[0016] 1. In this utility model, the cuff, pressure patch, and pad are connected by easy-tear threads to form an integrated structure. This integrated structure is like a rectangular piece of paper. When picking up a piece of paper, all three are picked up together, making it difficult to miss any device. The entire structure can be easily and quickly rolled up or folded, making it easy to store and take out. In addition, the cuff is arranged longitudinally and the pressure patch is arranged horizontally, which matches the orientation of the patient and medical staff during blood drawing, making it easy to operate. During use, the cuff can be tied to the arm by tearing the easy-tear thread. After blood drawing is completed, another set of easy-tear threads can be torn to attach the pressure patch to the needle hole, greatly improving the overall blood collection efficiency.

[0017] 2. In the present invention, two tear lines are provided on each side between the pad main body and the cuff, and a tear strip is formed between the two tear lines; when the binding section of the cuff needs to be separated from the pad main body and tied, the tear strip can be torn off from the pad main body conveniently and quickly, and the cuff can be tied to the arm in a timely and efficient manner, thereby greatly improving the efficiency of blood collection.

[0018] 3. In the present invention, one end of the tear strip is set as a cylindrical surface, and a gap is left between the cylindrical surface and the connecting part, so that when tearing the tear strip, it is more convenient and quick to pick up and grab the cylindrical surface of the tear strip, and tear off the tear strip more conveniently and quickly.

[0019] 4. In this utility model, the patch body is provided with a central airbag and air storage bags on either side of the airbag. During application, the gas in the air storage bags is squeezed into the airbags. After the patch is applied, most of the gas enters the airbags, leaving a small amount or no gas in the air storage bags. Because the gas in the airbags is pre-compressed during application, the airbags can squeeze the needle eye and the small area around the needle eye after the patch is applied. During use, only the airbags apply pressure to the skin, and the pressing area of the airbags is relatively small, which does not tighten the skin and affect blood circulation. This pressure patch is more convenient to use, fully freeing up the other hand, suitable for various situations, and more safe and reliable to use.

[0020] 5. In the present invention, a sealing line formed by hot pressing is provided in the middle of the airway; before use, the sealing line is in a sealed state, and the gas in the air storage bag cannot enter the airbag through the airway; when in use, the airbag area is first pressed against the skin, and then the air storage bag is pressed hard, the sealing line is stretched, and the gas in the air storage bag enters the airbag, and most of the gas is located in the airbag due to the pre-tightening force applied on both sides of the pressure patch during fitting, and presses the needle hole and the surrounding area; because the airbag is pressed against the skin at the beginning, and then gas is filled to expand the airbag, the needle hole and the needle hole area are effectively pressed, and the use of the pressure patch is safer and more reliable.

DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in combination with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0034] Therefore, based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.

[0035] Example 1

[0036] A combined sterile drape is designed to integrate a cuff and a pressure patch onto the drape to form a whole drape. The cuff and the pressure patch can be separated separately when in use, and used to tie the arm during blood collection, and to be applied to the needle eye and the surrounding area for pressing after blood collection, thereby improving blood collection efficiency.

[0037] First of all, it should be noted that the sterile drape does not mean that the drape needs to be used in a sterile environment, but that the drape itself is sterile.

[0038] This combined sterile drape includes a rectangular drape body 5, the length of which aligns with the patient's arm during use. A compression cuff 6 is attached to the top of the drape body 5, running along its width. The drape body 5 and the cuff 6 are connected by a central connecting portion 9 and two tear lines 8 on either side of the connecting portion 9. During use, the cuff 6 can be separated from the drape body by tearing the tear lines 8 apart, leaving free ends. Medical personnel can then manually tie the free ends of the cuff 6 to the patient's arm, achieving pulse compression.

[0039] In addition, a pressure patch 7 is connected to one side of the main body 5 (usually the right side of the medical staff) through an easy-tear line 8. The pressure patch 7 is arranged along the length of the main body 5. When in use, after the blood is drawn, the pressure patch 7 is torn off by hand and pasted on the needle hole to press the needle hole and the surrounding area.

[0040] It should be noted that the above-mentioned tear line 8 is a dotted line crack, that is, a crack evenly opened along the direction of the tear line 8. Under the action of external force (tearing force), it is very easy to be torn along the track of the tear line 8. In addition, the compression belt 6 is an elastic belt, which is convenient for better achieving the compression effect.

[0041] The combined sterile drape is used as follows: the medical staff first lays the sterile drape on the corresponding position, and the patient places his arm on the sterile drape; then the medical staff tears off the easy-tear lines 8 between the two sides of the compression cuff 6 and the drape body 5, holds the free ends of the compression cuff 6 at both ends and wraps the free ends of the compression cuff 6 around the patient's arm and ties it to the replaced arm (the tying method is consistent with the existing tying cuff 6); then the medical staff performs the blood collection operation; finally, after the blood collection is completed, the pressure patch 7 on the other side is torn off, and the pressure patch 7 is pasted on the needle eye, the compression cuff is released, and the needle eye and the surrounding area are pressed by the pressure patch 7 to complete the blood collection work, and the sterile drape is collected (the drape and the drape connected to it are collected together) for medical waste disposal.

[0042] Example 2

[0043] In order to better separate the drape body 5 from the free end of the cuff 6 and facilitate pinching the free end of the cuff 6 for tying, based on Example 1, two easy-tear lines 8 are provided on each side between the drape body 5 and the cuff 6, and a tear strip 11 is formed between the two easy-tear lines 8 on the same side. By pinching the tear strip 11 and tearing it along the direction of the easy-tear line 8, the entire tear strip 11 can be torn off from between the drape body 5 and the cuff 6, thereby forming a gap between the drape body 5 and the cuff 6 at the position where the tear strip 11 originally was. The two ends of the cuff 6 at the tear strip 11 form free ends, which can be used to tie around the patient's arm.

[0044] Furthermore, preferably, a cylindrical surface 81 is provided at one end of the tear strip 11 near the connecting portion 9, and the other end of the tear strip 11 can be flush with the end surface of the drape body 5, with a gap 10 formed between the cylindrical surface 81 and the corresponding connecting portion 9. Due to the gap 10 and the cylindrical surface 81, medical personnel can more conveniently and quickly pinch one end of the cylindrical surface 81 of the tear strip 11 and tear the tear strip 11 off the drape body 5 more conveniently and quickly.

[0045] During use, the medical staff pinches the tear strip 11 with their hands and tears it along the direction of the easy-tear line 8, tearing the tear strips 11 on both sides off the pad body 5 (they can tear them one by one or both together, and the medical staff can tear them according to the specific situation); then, the medical staff pinches the free ends of the compression cuff 6 with both hands (one free end in each hand) and ties the cuff 6 on the patient's arm.

[0046] Example 3

[0047] This embodiment provides a specific structure of a sterile pressure patch, the purpose of which is to press the needle hole and the surrounding area through the pressure patch, without the user having to manually press the needle hole and the surrounding area continuously, thereby freeing the user's hands and making the pressure patch more convenient to use.

[0048] This pressure patch comprises a long, rectangular patch body 2, with a drug layer 4 positioned in the middle of its bottom. This drug layer 4 not only sterilizes and disinfects, but also accelerates blood clotting at the needle prick, quickly stopping bleeding. Adhesive layers 3 are positioned on either side of the bottom of the patch body 2, flanking the drug layer 4. These layers allow the pressure patch to be adhered to the skin. The patch body 2, drug layer 4, and adhesive layer 3 are arranged in the same manner as a Band-Aid.

[0049] To increase the pressure applied to the needle eye and surrounding area, and to enhance the pressure patch's compressive effect, this embodiment incorporates an innovative structural design for the patch body 2: an airbag 23 is positioned in the central region of the patch body 2. This airbag 23 is inflated by filling it with gas, applying pressure to the skin. Air reservoirs 21 are located on either side of the airbag 23 within the patch body 2, each connected to the same airbag 23 via corresponding air passages 22.

[0050] During use, first squeeze the airbag 23 to fill the air storage bags on both sides with gas, then place the deflated airbag 23 against the skin at the needle eye. Then, gradually adhere the adhesive layer 3 on one side of the pressure patch to the skin, pressing the air storage bag 21 during the application process. The gas in the air storage bag 21 is then filled into the airbag through the airway 22, tightening the pressure patch. Then, gradually adhere the adhesive layer on the other side of the pressure patch to the skin, again pressing the air storage bag 21 during the application process, and tightening the pressure patch (the purpose of tightening is to prevent the gas in the airbag from flowing back into the air storage bag). In this way, most of the gas will fill the airbag, causing it to expand, pressing the needle eye and the surrounding area.

[0051] During use, only the airbag applies pressure to the skin. The airbag's small pressing area prevents constriction and blood flow. This pressure patch is convenient to use, freeing up your other hand for safer, more reliable, and suitable for a variety of situations. It effectively prevents bruising caused by insufficient pressure. It also addresses the problem of some patients with poor coagulation function requiring extended pressure after blood draws, and addresses the issue of patients traveling alone to the hospital with both hands free after a blood draw. The patch is also suitable for use after intravenous infusions.

[0052] It should be noted that the sterile pressure patch involves original innovation, and the applicant has separately filed a patent application for the sterile pressure patch and requested protection. The patent application was filed on the same day as this application.

[0053] Example 4

[0054] To reduce the need to squeeze the airbag 23 before applying the pressure patch, the airbag 23 is kept in a deflated (non-inflated) state before use. Based on Example 3, a sealing line 24 is provided in the middle of each air channel 22. This sealing line 24 is formed by heat-pressing, so that it can be broken open by increasing air pressure, allowing gas to enter the airbag 23.

[0055] Before use, the sealing line 24 is in a sealed state and the airbag 23 is in a deflated state; when in use, first fit the deflated airbag on the skin, then press the air storage bag 21 on one side hard, the pressure inside the air storage bag 21 increases, and the sealing line 24 in the corresponding airway 22 is broken, the gas in the air storage bag 21 is filled into the airbag 23, and the pressure sticker on that side is tightened and pasted; then press the air storage bag 21 on the other side hard, similarly, the pressure inside the air storage bag 21 increases, the sealing line 24 in the corresponding airway 22 is broken, the gas is filled into the airbag 23, and the pressure sticker on that side is tightened and pasted.

[0056] Example 5

[0057] In order to prevent the gas that has entered the airbag 23 from flowing back into the air storage bag 21 during the application of the pressure patch, the structure of the air storage bag 21 is further innovated based on Example 3 or Example 4. That is, an adhesive layer 25 is provided on the inner upper wall and the inner lower wall of the air storage bag 21. When the gas in the air storage bag 21 is filled into the airbag, the inner upper wall and the inner lower wall of the air storage bag 21 can be attached and bonded together.

[0058] During use, the air storage bag 21 is pressed, and the gas in the air storage bag 21 is filled into the airbag 23. In the process of pressing the air storage bag 21, the inner upper wall and the inner lower wall of the air storage bag 21 are attached and adhered together, thereby effectively preventing the gas in the airbag 23 from flowing back into the air storage bag 21.

[0059] A breathable and waterproof layer 1 is provided on the top surface of the sticker body 2 , and the breathable and waterproof layer 1 is a TPU film.

[0060] TPU, short for thermoplastic polyurethane film, is a non-porous, hydrophilic film. Since TPU film itself has no pores, it naturally has excellent water-repellency. The breathability of TPU film is primarily achieved through its hydrophilic properties. By utilizing the difference in vapor pressure inside and outside the film, vapor is transferred from areas of high pressure (between the pressure patch and the skin) to areas of low pressure (outside the pressure patch), thus achieving breathability.
