Description

A medical ice pack

technical field

The utility model relates to the field of small medical instruments, in particular to a medical ice bag.

Background technique

Ice packs are one of the most commonly used small medical devices in hospital nursing departments. Ice packs are commonly used in acute trauma, such as surgery, sports injuries, high fever and inflammation. Ice compress therapy uses the physical effect of cold to cause changes in the body's circulation and metabolism through the skin, relieve local tissue congestion and bleeding, shrink capillaries, slow down blood flow, reduce tissue temperature and cell metabolism, thereby reducing swelling and stopping bleeding. , relieve pain and inhibit the spread of inflammation.

When human tissues, especially soft tissues, are injured, they will enter the emergency injury period of swelling, swelling, itching, heat and pain. The physiological response of the human body varies significantly with temperature changes. When the temperature drops to 20 degrees Celsius, the pain nerve conduction will slow down or be blocked; when the temperature is lower than 10 degrees Celsius, it can relieve the tissue emergency reflex and make the injured muscles and tendons hurt. The injury is not exacerbated by the autologous tissue stress response. Therefore, early local cold compress cooling can effectively protect the body from secondary damage.

In addition, the temperature of the ice compress should not be too low, and the time of each ice compress should not be too long, otherwise it will frostbite the skin or soft tissue.

Although the therapeutic effect of ice packs is remarkable, but limited by the existing ice packs, there are still many defects and deficiencies in ice packs. For example, most of the common ice packs will solidify into lumps after being frozen, and it is difficult to completely fit the ice packs, especially Joints or body curves; ordinary ice packs cannot regulate the temperature after being applied to the patient's skin surface, cannot ensure that the temperature of the ice compress is within an appropriate range, cannot prevent frostbite, and cannot ensure that the emergency response of the damaged part is suppressed in time; Ordinary ice packs do not have ice pack reminders when the time comes, and when the patient has a heavy workload, the ice packs will not be removed and replaced in time.

Utility model content

A further technical solution is: the temperature slowing layer is memory foam.

A further technical solution is: the temperature detector is a thin-film thermistor temperature sensor.

A further technical solution is: the control unit further includes a display connected to the control output terminal of the controller.

A further technical solution is: the two ends of the spacer in the length direction and the upper and lower surfaces are sewn with Velcro that can be bonded to each other.

A further technical solution is: an opening is left on one side of the pocket, and a pocket cover is provided at the opening. The pocket cover and the pocket body are interlayer structures, and the interlayer is provided with thermal insulation materials.

The beneficial effects produced by adopting the above-mentioned technical scheme are:

The medical ice pack is made of medical latex and filled with 15% sodium chloride solution. After freezing, the sodium chloride solution becomes a smoothie, which is soft and can be shaped arbitrarily. The medical latex can be extended with the smoothie and is not easy to break The shortcomings of traditional ice packs, which harden after freezing and are not easy to fit with the ice application site, increase the comfort of patients.

When the medical ice pack is used, since the temperature-slowing layer adopts memory foam, it can preliminarily alleviate the discomfort caused by the low temperature of the ice pack to the patient, and can also absorb the water vapor produced during the melting process of the ice pack. Due to the slow resilience of memory foam, it can adapt to the surface shape of external pressure through stress relaxation, and can deform with the shape of the human body, air bag or ice bag, so that the pressure can be evenly distributed on the surface of the damaged part of the human body, avoiding microcirculation compression, making Patients are more comfortable. In addition, memory foam also has antibacterial, anti-mite and anti-corrosion properties, and can maintain a certain degree of cleanliness. It generally contacts the human body and can be used for a long time without cleaning and without exposure to the sun for disinfection.

When the medical ice pack is in use, due to the elastic air bag in the septum, when the slow temperature layer cannot completely alleviate the low temperature of the ice bag, the air at room temperature can be blown into the elastic air bag through the inflatable unit to reduce the thermal conductivity between the ice bag and the human body , to further alleviate the discomfort brought by the low temperature of the ice pack to the patient. When the human body adapts to the low temperature of the ice pack, the controller will control the solenoid valve in time to empty the air in the elastic air bag, so as to achieve a better ice compress effect.

When the medical ice pack is in use, a temperature detector is placed on the side where the ice pack is in contact with the human body; it can monitor the body temperature of the damaged part of the human body in real time, transmit the measured temperature to the controller, and display it on the monitor. It is convenient to monitor the body temperature of the damaged part of the patient. If the temperature exceeds the effective temperature range of ice compress, the alarm will remind the nursing staff to adjust or replace it in time, so as to avoid frostbite on the damaged part of the patient caused by too low temperature of ice compress, or too high temperature of ice compress to prevent It can inhibit the emergency response of the damaged part and cause secondary injury to the patient.

When the new medical ice pack is in use, its timer can time the duration of the ice pack, and when the ice pack expires, an alarm signal will be output through the controller to prompt the nursing staff to remove the ice pack, which solves the problem of removing the ice pack when the patient’s workload is heavy. untimely problem.

As shown in FIGS. 1-2 , a medical ice bag includes an ice bag 1 , an ice bag jacket 2 , an inflation unit 3 and a control unit 4 .

The ice pack 1 is made of medical latex material, and its interior is filled with 15% sodium chloride solution that forms ice sand after freezing. Medical latex has good elasticity and is not easy to break. The 15% sodium chloride solution is like a smoothie after freezing. It is soft and can be shaped arbitrarily. The combination of the two materials ensures no leakage and can be completely attached to the injured part of the patient.

The ice bag jacket 2 includes a septum 21 and a pocket 22, and the pocket 22 is used to hold the ice bag 1. Putting the ice pack 1 in the pocket 22 facilitates the replacement of the ice pack 1 , and only the ice pack 1 needs to be frozen during freezing, which takes up less space. Both the ice bag coat 2 and the ice bag 1 can be used repeatedly by patients, which reduces the medical expenses of patients.

The spacer 21 is fixed below the pocket 22 in order to relieve the discomfort caused by the low temperature of the ice pack 1 and to prevent frostbite.

The spacer 21 includes an elastic airbag 211, which is designed to be flat and long, so as to form a ring when the ice pack 1 covers the human body. The elastic airbag 211 is wrapped with a temperature-slowing layer 212 , and the temperature-slowing layer 212 is wrapped with an elastic coat 213 . When the slow temperature layer 212 cannot completely alleviate the low temperature of the ice pack 1, the air at room temperature can be filled into the elastic airbag 211 through the inflatable unit 3, so as to reduce the thermal conductivity between the ice pack 1 and the human body, and further alleviate the low temperature of the ice pack 1. coming discomfort.

The slow temperature layer 212 adopts memory foam, which can initially alleviate the discomfort caused by the low temperature of the ice pack 1 to the patient, and can also absorb the water vapor produced during the melting process of the ice pack 1 . Because memory foam has slow resilience, it can adapt to the surface shape of external pressure through stress relaxation, and can deform with the shape of the human body, elastic airbag 211 or ice pack 1, so that the pressure can be evenly distributed on the surface of the damaged part of the human body to avoid microcirculation compression to make the patient more comfortable.

In addition, memory foam also has antibacterial, anti-mite and anti-corrosion properties, and can maintain a certain degree of cleanliness. It generally contacts the human body and can be used for a long time without cleaning or exposure to the sun.

The elastic jacket 213 is made of medical elastic non-woven fabric, which is not only soft and comfortable to the skin, but also moisture-proof and breathable.

The inflation unit 3 includes an air tube 31 , one end of the air tube 31 is sealed and connected to the side of the elastic air bag 211 away from the human body, and the other end is connected to an air pump 33 for inflating the elastic air bag 211 . Trachea 31 stretches out the part outside elastic air bag 211 and is provided with electromagnetic valve 32 with air intake, exhaust, pressure maintaining function; When it is removed, the air in the elastic airbag 211 will not leak, so that multiple patients can share the inflator 33, which can save resources.

Described control unit 4 comprises temperature detector 41, timer 42, controller 43 and display 44, alarm 45; Described temperature detector 41 is fixed on the side that ice pack coat 2 and human body contact; The signal input end is connected to the temperature detector 41 and the timer 42 , and the control output end is connected to the display 44 , the alarm 45 and the solenoid valve 32 . The controller 43 can control the real-time display of the measured temperature, send an alarm signal in time when the temperature exceeds the range or the ice application is due, and control the solenoid valve 32 to keep the elastic air bag 211 for a certain period of time, so that the patient can adapt to the low temperature of the ice pack 1 and keep the pressure When the time expires, the controller 43 will control the solenoid valve 32 to automatically discharge the gas in the elastic airbag 211 .

The temperature detector 41 is a thin-film thermistor temperature sensor, which is ultra-thin, ultra-thin, bendable, and can be well attached to the surface of the human body without making the patient feel uncomfortable. In addition, because it is protected by a film, it is more resistant to humidity. When the ice pack 1 melts and generates moisture, the performance will not be affected.

The two ends of the spacer 21 in the length direction are sewn with magic stickers 23 that can be bonded to each other on the upper and lower surfaces respectively. One end is a child sticker, and the other end is a mother sticker. During ice compressing, the medical ice pack can be wrapped around the injured part of the patient in a ring, and then the mother-in-law stickers of the Velcro 23 are bonded, which is beneficial to fix the medical ice pack on the affected part and prevent falling from falling. Because different parts of the human body have different thicknesses, even patients with different fat and thin body parts have different thicknesses. Therefore, the medical ice pack needs to be able to adjust the size of the formed ring. At this time, you can adjust the Velcro 23 The length of the glue between the stickers is achieved.

In order to facilitate replacement, an opening is left on one side of the pocket 22. In order to completely isolate the air, a pocket cover 221 is provided at the opening; Material.

During use, pack the frozen ice pack 1 into the pocket of the ice pack coat 2, then bind the ice pack coat 2 equipped with the ice pack 1 to the injured part of the patient, adjust the tightness of the Velcro 23, and use the air pump 33 to the elastic air bag 211 is filled with air at room temperature, and after the inflation is completed, the air pump 33 is removed, and the switch of the timer 42 is pressed at the same time to start timing. At this point, the temperature detector 41 on the side where the ice bag jacket 2 contacts the human body starts to monitor the body temperature of the damaged part of the human body, and displays it on the display 44 .

Within a certain period of time set by the controller 43, the electromagnetic valve 32 will be in a pressure-holding state, and the air in the elastic airbag 211 will not leak. The controller 43 will control the solenoid valve 32 to switch to the exhaust state, and the air in the elastic air bag 211 will be emptied under the pressure of the elastic outer casing 213 .

During the ice application, the temperature signal of the temperature detector 41 and the time signal of the timer 42 will be fed back to the controller 43. When the temperature detected by the temperature detector 41 exceeds the effective temperature range of the ice application, the controller 43 will turn on the alarm Device 45, alarm device 45 reports to the police. Nurses will come when the alarm is heard, and when the temperature is too low, they will re-inflate and adjust the temperature, and when the temperature is too high, the ice pack 1 will be replaced. When the ice application time reaches the time set by the controller 43, the controller 43 will also connect the alarm 45, and the alarm 45 will give a voice prompt of "time is up", and the nursing staff will come to remove the medical ice pack. It avoids frostbite on the damaged part of the patient caused by too low ice temperature or too long time of ice compress, and also avoids secondary injury to the patient caused by the failure of the emergency response of the damaged part to be suppressed by the high ice compress temperature.

The above are only preferred embodiments of the utility model, and anyone who makes some simple modifications, deformations and equivalent replacements to the utility model according to the content of the utility model all falls within the protection scope of the utility model.
