Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to an absorbable cotton sheet with hemostatic effect. Background Art

[0002] Vaginal bleeding is a common problem for patients after gynecological surgery, especially after egg retrieval for in vitro fertilization. Bleeding is mainly caused by bleeding at the vaginal puncture site.

[0003] At present, the commonly used method of hemostasis in clinical practice is to pack the vagina with gauze to control bleeding by compression. After about 1-2 hours, the medical staff will remove the gauze.

[0004] However, there are some obvious shortcomings in the simple compression hemostasis method. First, the hemostasis effect is general, and most patients will still have varying degrees of bleeding after removing the gauze. Secondly, packing gauze and later removal will cause obvious discomfort to the patient and there is a risk of damaging the surgical wound. In addition, the gauze needs to be collected and processed separately after use, which increases the workload of medical staff. At the same time, the existing method cannot accurately grasp the patient's bleeding volume.

[0005] Therefore, there is an urgent need for a new type of hemostatic product that can effectively control bleeding, avoid the discomfort caused by secondary removal, and does not require separate treatment. At the same time, the amount of bleeding can be monitored to make up for the various shortcomings of existing hemostatic methods. Utility Model Content

[0006] In order to solve the problems of the prior art, the embodiment of the utility model provides an absorbable cotton sheet with hemostatic effect. The technical solution is as follows:

[0007] On the one hand, an absorbable cotton sheet with hemostatic effect is provided, comprising: a porous hemostatic layer for absorbing blood and promoting hemostasis; an outer membrane surrounding the outside of the porous hemostatic layer for controlling the dissolution rate; characterized in that: the porous hemostatic layer and the outer membrane are both made of biodegradable materials, so that the entire cotton sheet can be completely dissolved and absorbed in the body.

[0008] Furthermore, the porous hemostatic layer comprises gelatin, chitosan and thrombin.

[0009] Furthermore, the outer membrane comprises hyaluronic acid.

[0010] Furthermore, a monitoring device is included for monitoring the amount of blood absorbed.

[0011] Furthermore, the monitoring device includes a test paper card with a color scale and a lead connecting the cotton piece and the test paper card.

[0012] Furthermore, the size of the cotton sheet is 65 mm×65 mm.

[0013] Furthermore, the estimated in vivo dissolution time of the cotton sheet is 4-6 hours.

[0014] The beneficial effects brought by the technical solution provided by the embodiment of the utility model are:

[0015] Excellent hemostatic effect The absorbable hemostatic cotton pad of the utility model adopts a porous structure design, which is conducive to rapid absorption of blood. At the same time, natural hemostatic agents chitosan and thrombin are added to the cotton pad, which can accelerate blood coagulation, thereby achieving a good hemostatic effect, which is better than the conventional gauze compression hemostasis method.

[0016] No need for secondary removal, improving patient comfort

[0017] Since the cotton pad and its materials are biodegradable, there is no need to remove it after use, which avoids the discomfort and risk of wound expansion and bleeding during removal, greatly improving the patient's comfort.

[0018] No need to handle separately, reducing workload Traditional gauze needs to be collected and handled separately after use, which brings extra work to medical staff. However, the cotton piece of the utility model can be completely dissolved and absorbed in the body, and no separate handling is required after use, which reduces the workload of medical staff.

[0019] The monitoring device facilitates the grasping of the amount of bleeding. The utility model designs a test paper card monitoring device, which can accurately grasp the patient's bleeding amount at any time. It is more accurate and reliable than the existing method of estimating based on experience alone, and is conducive to evaluating the condition and formulating treatment plans.

[0020] Disposable, hygienic and safe cotton pads are disposable products that are sterile packaged and do not require disassembly and assembly when used. They are easy to operate and avoid the risk of cross infection that may be caused by repeated use of traditional gauze.

[0021] In conclusion, the absorbable hemostatic cotton sheet of the utility model has outstanding innovation and superiority over the prior art, brings great convenience to clinical application, and has broad application prospects. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings required for use in the description of the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work.

[0023] Figure 1 It is a schematic diagram of an absorbable cotton sheet with hemostatic effect according to an embodiment of the utility model. DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0025] The utility model is an absorbable cotton sheet with hemostatic effect, which aims to solve the problems of inconvenience and poor hemostatic effect of existing hemostatic methods. Figure 1 The cotton piece is composed of a porous hemostatic layer 1 and an outer membrane 2, both of which are made of biodegradable materials, so that the entire cotton piece can be completely dissolved and absorbed in the body without having to be taken out again.

[0026] The main material of the porous hemostatic layer 1 is gelatin, which has good blood absorption and biocompatibility. Chitosan, a natural high molecular weight polysaccharide, is also added, which has the effect of stopping bleeding and promoting wound healing. In addition, a small amount of thrombin is added to further promote hemostasis. The above materials are cross-linked and dried to form a porous structure, which is conducive to rapid absorption of blood.

[0027] The outer layer 2 is mainly made of hyaluronic acid, which has excellent biocompatibility and degradability. The function of the outer layer 2 is to control the dissolution rate of the entire cotton sheet to prevent it from dissolving too quickly. By adjusting the cross-linking degree and coating thickness of the hyaluronic acid, the dissolution time of the cotton sheet in the body can be controlled to be about 4-6 hours.

[0028] In addition, an innovative feature of the present invention is the design of a monitoring device 3 for monitoring the amount of blood absorbed. The monitoring device 3 includes a test paper card 31 with a color scale and a lead 32 connecting the cotton piece and the test paper card. When the cotton piece absorbs blood, the blood penetrates into the test paper card through the lead, and the color of the test paper deepens as the amount of blood increases. Medical staff can judge the amount of bleeding based on the color of the test paper corresponding to the scale.

[0029] The size of the cotton sheet is 65mm×65mm, which is comparable to the size of a common gauze piece. When in use, open the sterile package and insert it into the body, and the other end of the lead wire is led out of the body and connected to the test paper card. After about 4-6 hours, when the cotton sheet is completely dissolved and absorbed, the test paper card and the lead wire can be taken out together.

[0030] In summary, the absorbable cotton pad with hemostatic effect of the utility model has the following advantages: disposable use, good hemostatic effect, no need to be removed, convenient monitoring of bleeding volume, etc., providing an effective way to solve relevant clinical needs.

[0031] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
