Description

Tourniquet with compression mechanism OBJECT OF THE INVENTION The invention, as the title of this descriptive document states, is a tourniquet with a compression mechanism. It is an innovation that offers advantages previously unknown within current techniques. TECHNICAL SECTOR The present invention falls within the sector of current needs of life in the subclass of medical or veterinary sciences and hygiene, especially in diagnosis, surgery and identification, specifically in the section on surgical instruments, devices or procedures, for example, tourniquets, as well as in the classification for tourniquets. STATE OF THE ART The present invention arises from observing that, after a blood extraction procedure using venipuncture technique, patients face difficulties in maintaining the necessary rest and applying constant pressure on the puncture point to avoid bleeding and possible hematoma. This situation causes discomfort, as it is common for patients to interrupt the pressure process when trying to put on a coat, use their mobile phone, or when they feel embarrassed to keep their arm uncovered in public. The lack of an adequate system not only compromises the effectiveness of post-puncture treatment, but also increases the risk of prolonged bleeding and the appearance of hematomas. Furthermore, in many cases, applying pressure to the puncture site requires healthcare personnel to cut adhesive tape and manually place a cotton ball, which increases the procedure time. It is also common for patients to be instructed to apply pressure to the puncture site after the blood draw, which can cause confusion or discomfort. Accordingly, this invention provides a tourniquet with a compression mechanism that acts in two phases: first, before the puncture, as a device that improves the visibility of the veins by exerting pressure around the forearm, allowing the restriction of blood flow through the vein, which causes the veins under the band to dilate, and makes it easier for the needle to reach one of the blood vessels, and subsequently, as a tourniquet designed to apply localized pressure at the puncture point. This ensures the prevention of bruising without the need for additional manual intervention, simplifying the process and freeing the patient from the need to apply strong manual pressure to the area. Furthermore, the device allows the patient to comfortably maintain their normal activities without discomfort, while also preserving discretion when used in public. Currently, there is no known existence of any tourniquet with a compression mechanism that presents structural and constitutive technical characteristics equal or similar to those described in this descriptive report, as claimed. DESCRIPTION OF THE INVENTION The object of the present invention is the creation of a tourniquet with a compression mechanism that provides a notable innovation within its field of application in the current state of the art, the characterizing details that make it possible being conveniently included in the final claims that accompany this description. The present invention relates to a tourniquet with a compression mechanism consisting of an elastic band equipped with a quick-release fastening mechanism (e.g., a hook-and-loop fastener such as Velcro (registered trademark)), as well as a protrusion contained within its structure on one side of the band. This protrusion allows for the application of focused pressure. The elastic band is thus configured to act in two phases: in the first phase, it improves venous visibility by applying compression to the antecubital fossa; and in the second phase, by repositioning the band, the protrusion exerts pressure on the puncture site, in order to reduce the risk of hematoma formation without requiring manual intervention. This invention effectively solves the challenges associated with post-puncture care after venipuncture, by providing a system that automatically and constantly maintains the necessary pressure on the puncture site, simplifying the procedure and preventing the patient from having to exert intense manual pressure on the area. Its innovative design works in two phases: first as a conventional tourniquet to facilitate visibility and venous access, and then as a focused compression mechanism that ensures hemostasis after blood extraction. This prevents the patient from interrupting the process by trying to put on a coat, handling objects, or due to discomfort from leaving their arm uncovered, which is particularly useful in public settings. By allowing the patient to resume their activities normally and discreetly, the user experience is optimized and the care time and operational burden of the health personnel are significantly reduced. In this invention, the elastic band must be of a suitable length to fit comfortably in the antecubital fossa and of sufficient width to ensure uniform pressure distribution around the forearm, allowing for controlled compression that temporarily restricts venous blood flow. It can be marketed in various sizes to select the appropriate length for each patient. This restriction causes dilation of the superficial veins located below the band, facilitating their visualization and access, and thus increasing the accuracy and effectiveness of needle insertion during venipuncture. Additionally, this elastic band may be equipped with a retractable protrusion mechanism that allows the protrusion to be moved outward from within its structure and, optionally, vice versa. In this case, the protrusion may be separated from the exterior by an elastic membrane, the configuration of which incorporates an opening with a diameter smaller than that of the protrusion itself. When the protrusion is squeezed, it is forced through the opening, since the band is elastic. This design allows the protrusion to protrude from the surface of the band by applying pressure, remaining in that position with stability during the post-puncture compression phase. Similarly, the elastic band can have two distinct sides, one smooth and the other with the integrated protrusion. In this configuration, during the first phase of use, the smooth side is in contact with the patient's skin, while the side with the protrusion faces outwards. Subsequently, in the second phase, the band can be turned over so that the side with the protrusion is in direct contact with the skin, aligning with the puncture point to exert effective localized pressure. Furthermore, the elastic band can be made of biodegradable or reusable materials that allow for a secure and comfortable fit to the patient's arm, while promoting environmental sustainability by reducing healthcare waste. Furthermore, the closing and release mechanism may include a sliding adjustment system for one end of the band. This system can be complemented with a locking mechanism that prevents recoil once adjusted, and with a release mechanism that allows it to be unlocked by pressure or other mechanical means, facilitating a quick and safe withdrawal. Furthermore, this locking and release mechanism can be configured as an adjustable system, based on clip, buckle or quick-release clasp elements, which guarantees efficient and simple handling by healthcare personnel, even in urgent or repetitive intervention conditions. As for the protuberance, it may have a circular or semicircular shape, generally with smooth edges, and have a rigid or semi-rigid core, in order to apply adequate pressure on the puncture point without causing excessive discomfort to the patient. Additionally, the protrusion is made of a sterile, medical-grade material that can be absorbent, capable of retaining the blood residue generated after extraction, thus eliminating the need to incorporate an additional gauze, which simplifies the procedure and reduces the handling of materials. Finally, the elastic band and the protrusion are integrated into a single, disposable, functional unit. This configuration maintains the stability and functionality of the protrusion during its retractable and expansive phases, without compromising its ability to exert effective and safe localized compression. In this way, the proposed solution not only improves the functionality and comfort of the tourniquet, but also optimizes its use in the healthcare context, providing an efficient and discreet experience for the patient. To use the tourniquet with compression mechanism, healthcare personnel must place the elastic band around the patient's arm, adjusting it comfortably to the antecubital fossa using the locking and release mechanism. This restriction induces dilation of the superficial veins, facilitating their visualization and access, and thus increasing the accuracy and effectiveness of needle insertion during venipuncture. Once the procedure is complete, the healthcare worker can activate or reposition the protrusion incorporated into the tourniquet, which applies localized pressure directly to the puncture site without further intervention. In other designs, the tourniquet is flipped over to position the protrusion toward the patient's body. The device maintains constant and effective compression, allowing the patient to continue their daily activities without compromising treatment or comfort. Finally, after the indicated time, the tourniquet can be easily removed and, if it is a disposable model, disposed of safely and in an environmentally friendly manner. EXPLANATION OF THE FIGURES To complete the description being made and in order to help in the better understanding of the characteristics of the invention, this descriptive report is accompanied, as an integral part thereof, by some figures in which, for illustrative and non-limiting purposes, the following has been represented. Figure 1: illustrates the tourniquet with compression mechanism. Figure 2: represents the application of the turnstile in the first phase. Figure 3: shows the application of the turnstile in the second phase. PREFERRED EMBODIMENT OF THE INVENTION. The compression tourniquet, the subject of the present invention, comprises an elastic band (1) equipped with a quick-release and locking mechanism (2), and a protrusion (3) on one side of the elastic band (1) that allows for the application of focused pressure. This elastic band (1) is configured to operate in two distinct phases: in the first phase, it is used to improve venous visibility by applying compression to the patient's antecubital fossa; while in the second phase, the protrusion (3) automatically acts on the puncture site, exerting localized pressure intended to reduce the risk of hematoma formation, all without requiring additional manual intervention by the healthcare professional. Preferably, the elastic band (1) is of sufficient length to allow it to fit comfortably around the patient's antecubital fossa, and of adequate width to ensure even pressure distribution during application. This configuration allows for controlled compression of the forearm, temporarily restricting venous blood flow and causing dilation of the superficial veins located beneath the band. This effect facilitates visualization and access, increasing the accuracy of needle insertion and contributing to both the effectiveness of the clinical procedure and the comfort of the patient. Alternatively, the elastic band (1) is equipped with a retractable mechanism that allows for the controlled displacement of the protrusion (3) within the elastic band (1) itself. This protrusion (3) is separated from the outside by an elastic membrane, in which an opening with a diameter smaller than that of the protrusion (3) is provided, allowing it to protrude from the elastic band (1) when controlled pressure is applied. This configuration ensures that, once protruded, the protrusion (3) remains stable in its position, thus guaranteeing safe and effective compression during the post-puncture phase. Preferably, the elastic band (1) has two distinct sides: one smooth and the other incorporating the protrusion (3). During the first phase of use, the smooth side is placed in direct contact with the patient's skin, while the side with the protrusion (3) faces outwards. Subsequently, in the second phase, the band is turned over so that the side with the protrusion (3) is in contact with the skin, aligning it properly with the puncture site to apply the necessary focused pressure. The elastic band (1) is typically made of biodegradable and / or reusable materials that allow for a comfortable and secure fit on the patient's arm. This selection of materials not only promotes good device functionality but also contributes to environmental sustainability by reducing the generation of clinical waste. Preferably, the locking and release mechanism (2) consists of a sliding adjustment system for one end of the elastic band (1). This system incorporates a locking mechanism that prevents the band from retracting once adjusted, as well as a release mechanism that allows it to be unlocked by pressure or other mechanical means, thus facilitating quick and efficient removal after use. In general, the locking and release mechanism (2) can be adjustable, configured by means of a clip, buckle or quick-release clasp system, which allows for simple and efficient handling by healthcare personnel, especially in contexts of rapid care or in outpatient procedures. Preferably, the protuberance (3) has a circular or semicircular shape, with smooth edges and a rigid or semi-rigid core, which allows sufficient localized pressure to be exerted to contain bleeding after puncture, without causing excessive discomfort to the patient. In another preferred configuration, the protrusion (3) is made of a sterile, absorbent material, which allows for the efficient retention of blood residues, thus eliminating the need for additional gauze. This simplifies the procedure and reduces the number of items required during blood collection or intravenous medication administration. Preferably, the elastic band (1) and the protrusion (3) are integrated into a single, disposable functional unit. This configuration ensures that the protrusion (3) remains contained and protected within the structure of the elastic band (1) while in its retractable phase, without compromising its expansion capacity or its ability to exert effective localized compression. This integration contributes to easier handling, faster application, and a higher level of safety and hygiene in the clinical setting. Having sufficiently described the nature of the present invention, as well as the manner of putting it into practice, it is not considered necessary to make its explanation more extensive so that any expert in the field may understand its scope and the advantages that derive from it, it being noted that, within its essentiality, it may be put into practice in other modes of embodiment that differ in detail from the one indicated as an example, and which will also achieve the protection sought provided that its fundamental principle is not altered, changed or modified.
