Description

Tourniquet and hemostat

Technical Field

The utility model relates to the technical field of medical instruments, in particular to a tourniquet and a hemostat.

Background

Patients with chronic renal insufficiency rely on hemodialysis for a long time to sustain life, and in hemodialysis treatment, fixed-point puncture is performed on arteries or veins, and the arterial or venous puncture site needs hemostasis. The traditional hemostasis method is manual compression, but the method is not only time-consuming and occupies nursing resources. Later, in clinic, the elastic bandage is adopted to stop bleeding through compression bandaging, although the materials are available, the price is low, the bleeding condition of local wounds is not easy to observe, and the tightness of the bandage is difficult to control. Along with the development of diagnosis and treatment technology, the hemostat gradually enters the visual field of people, and the hemostat performs local compression on the puncture part through the special device to complete hemostasis, so that compared with the bandage hemostasis, the hemostat has remarkable hemostasis effect, is convenient for patients and medical staff, and improves the use comfort of the patients while reducing clinical complications.

Currently, the most commonly used hemostat in the medical field is the balloon compression hemostat. The gasbag pressurization type hemostat mainly comprises a wrist strap, a gasbag, a supporting plate, an inflation injector and the like, and the gasbag is injected with air to expand to the wrist side to generate pressure, so as to compress a puncture part to complete hemostasis. However, due to the difference of wrist structures of patients, different manipulations of operators, different tightness of fixation and the like, the condition of injecting equal amount of gas but different pressure can occur, and the difference of hemostatic effects is easy to occur.

The air bag pressurizing type hemostat cannot judge the overflow of blood flow, so that a doctor cannot be guided to timely adjust the inflation pressure of the air bag of the hemostat, when the hemostasis pressure is too small, hemostasis is not achieved, and when the hemostasis pressure is too large, long-time improper pressure can also cause forearm swelling, numbness, skin damage and even limb necrosis.

Therefore, how to indicate the overflow of blood flow so as to facilitate the doctor to adjust the inflation pressure of the compression air bag in time is a technical problem which needs to be solved by the person skilled in the art at present.

Detailed Description

The utility model aims at providing a tourniquet which can indicate the overflow of blood flow so as to facilitate doctors to adjust the inflation pressure of a compression air bag in time;

another core of the present utility model is to provide a hemostat having the above tourniquet.

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 1 and 2, the embodiment of the present utility model discloses a tourniquet 100, wherein the tourniquet 100 can compress a bleeding point by applying pressure to the bleeding point by inflating a compression balloon 104.

The tourniquet 100 includes a strap 101 and a compression balloon 104. The binding band 101 is used for being wound on a part to be haemostatic, and a puncture point is usually located at the wrist, so that the part to be haemostatic is the puncture point of the wrist, and the binding band 101 can be wound on the wrist.

For ease of understanding, depending on the function, the regions at both ends of the strap 101 are defined as fastening regions, and the region between the fastening regions at both ends is defined as a compression region. The fastening area of one end of the strap 101 is provided with a first fastening member 102 and the fastening area of the other end of the strap 101 is provided with a second fastening member 103, the first fastening member 102 being adapted to be connected to the second fastening member 103. After the strap 101 is wrapped around the site to be haemostatic (e.g. wrist), the strap 101 may be secured to the site to be haemostatic by the first fastener 102 for connection with the second fastener 103.

The compression balloon 104 is arranged in a compression area, the compression area is an area close to a bleeding point, and the compression balloon 104 is provided with a blood flow overflowing mark 105 for pressing the bleeding point, wherein the blood flow overflowing mark 105 comprises a plurality of similar patterns, and the similar patterns are patterns with the same shape but different sizes. Each similar graph is nested in sequence, namely, the graph with larger size is sleeved on the outer side of the graph with smaller size, and the bleeding amount can be intuitively judged by checking the graph where blood flow is stained. The compression balloon 104 is used to compress at the bleeding point, specifically the middle of the blood flow extravasation marker 105 should be compressed at the bleeding point. The compression balloon 104 has an inflation/deflation port 106, through which port 106 air can be inflated into the compression balloon 104, which in turn adjusts the pressure of the compression balloon 104 against the bleeding site.

In order to enable the blood flow overflow mark 105 to be observed, the compression region and the compression balloon 104 are both made of transparent materials, so that the blood flow overflow mark 105 can be observed through the compression region and the compression balloon 104, and the fastening region can be made of transparent materials.

In summary, in the tourniquet 100 provided by the present utility model, the compression balloon 104 is provided with the blood flow overflow mark 105 for pressing the bleeding point, and the blood flow overflow mark 105 includes a plurality of similar patterns nested in sequence. The doctor can determine how much blood overflows by observing the position of the blood flow to the blood flow overflow mark 105, and the more the blood flow overflows, the larger the blood flow overflow range spreads to the outer circle. When it is judged that blood continuously overflows through the puncture, the inflation pressure of the compression air bag 104 can be adjusted first, and if the compression air bag 104 is adjusted to stop bleeding, the compression air bag 104 is deflated and then the binding belt 101 is re-bound and then inflated. The present utility model can not only easily align the compression balloon 104 with the puncture site by the blood flow overflow mark 105, but also judge the magnitude of the blood flow overflow amount, and timely adjust the inflation pressure of the compression balloon 104.

In this embodiment, the blood flow overflow mark 105 may include a plurality of circles (i.e., the similar pattern is a circle) arranged concentrically, and the diameter differences of two adjacent circles are equal. For example, the diameters of the respective circles are 5mm, 10mm, 15mm, etc. are progressive with a diameter difference of 5mm. It should be noted that the blood flow overflow mark 105 may further include a plurality of concentrically arranged squares, ovals, equilateral triangles, etc., and the present utility model is not limited to the form of circles. The spacing between two adjacent similar patterns can also be designed to be other, and can be specifically designed according to the bleeding part and the conventional bleeding amount. For example, in the conventional case, a puncture with a large bleeding amount can be designed with a correspondingly large pitch, whereas a puncture with a smaller pitch can be designed.

Further, the compression balloon 104 has a rectangular structure, and one side of the compression balloon 104 is connected to the compression region, and the other side is disconnected from the compression region. That is, compression balloon 104 has only one side edge attached and restrained to the compression zone of strap 101 and the other side edge remains free. The compression balloon 104 is hinged on the compression area of the bandage 101, and after inflation, the compression balloon 104 can have a larger degree of freedom, so that the compression balloon 104 can be unconstrained to charge more gas, provide greater pressure and compress the puncture site.

Taking the compression balloon 104 as a square, the side length may be 2.0cm by 2.0cm. The side length of the compression balloon 104 may be set to other lengths according to the requirements, for example, the hemostasis site.

Since the middle of the blood flow escape mark 105 is pressed at the bleeding point and the maximum inflation area of the pressing balloon 104 is located at the middle of the pressing balloon 104, the blood flow escape mark 105 is provided in the middle of the pressing balloon 104 in this embodiment. That is, the blood flow overflow mark 105 is arranged in the maximum expansion area of the compression air bag 104, so that a larger compression force can be provided for the bleeding point, and a better hemostatic effect can be achieved.

The binding band 101 may be made of a polyolefin material such as polyvinyl chloride, polyethylene, polypropylene, polybutadiene, and EVA (ethylene-VINYL ACETATE copolymer), a polyester material such as PET (polyethylene glycol terephthalate, polyethylene terephthalate), PBT (polybutylene terephthalate ), a thermoplastic elastomer such as polyvinylidene chloride, silicone, polyurethane, polyamide elastomer, polyurethane elastomer, and polyester elastomer, or a combination of any of these materials (e.g., a mixed resin, a polymer alloy, and a laminate). The compression balloon 104 may be made of polyethylene, polypropylene, polyurethane, or the like.

In one embodiment of the present utility model, the first fastener 102 is disposed on one side surface of the strap 101 and the second fastener 103 is disposed on the other side surface of the strap 101. The first fastener 102 and the second fastener 103 may each be a velcro. The first fastener 102 and the second fastener 103 are arranged on different sides of the strap 101 such that after the strap 101 is wrapped around the wrist, the first fastener 102 and the second fastener 103 can be brought into engagement with each other to achieve the connection. It should be noted that the first fastener 102 and the second fastener 103 may also be snaps, double-sided tape, and the like, and are not limited to the specific fastening form of the velcro tape. The length of the first fastener 102 and the second fastener 103 on the strap 101 should be able to meet the wrist thickness of most people.

The embodiment of the utility model also discloses a haemostat, which comprises a tourniquet 100 and an inflation and deflation device 200, wherein the tourniquet 100 is the tourniquet 100 disclosed in the embodiment above, the compression balloon 104 is provided with an inflation and deflation port 106, and the inflation and deflation device 200 is used for inflating and deflating the compression balloon 104 through the inflation and deflation port 106. The inflation and deflation device 200 can be an inflator or a syringe. When a syringe is selected as the air charge and discharge device 200, a check valve that is communicated in the air charge direction needs to be provided on the air charge and discharge port 106, so that the pressure pressing the air bag 104 can be maintained under the action of the check valve when the syringe is pulled out.

The valve core of the one-way valve is kept in a cut-off state under the action of the spring, so that the gas in the pressing air bag 104 cannot be discharged from the air charging and discharging port 106 through the one-way valve, and the air pressure in the pressing air bag 104 is kept. When inflation or deflation is needed, the injector is inserted into the valve body of the one-way valve, the injector pushes the valve core to compress the spring, so that the valve core is separated from the cut-off position, the one-way valve is in a conducting state, at the moment, the inflation and deflation port 106 is communicated with the injector, the injector is pushed to be inflated into the compression air bag 104, and after the injector is pulled out, the spring pushes the valve core to reset, so that the one-way valve is in the cut-off state. The pressure pressing the balloon 104 is maintained. When deflation is desired, the one-way valve is also inserted with the syringe such that the one-way valve is in a conductive state and can be withdrawn outwardly through the syringe to withdraw the gas that is forced into the balloon 104.
