Description

Technical Field

[0001] The invention relates to the technical field of medical equipment, in particular to a Chinese medicine external application nursing device for preventing phlebitis. Background Art

[0002] Phlebitis is an inflammation of the vein wall, which is mainly manifested by local redness, swelling and pain in the affected limb, and some are accompanied by nodules. The causes of phlebitis are generally divided into two situations: the first is phlebitis caused by external factors such as long-term infusion, intravenous catheterization, trauma, etc. This situation can generally be cured after the treatment is completed. The second is phlebitis caused by internal factors such as high blood lipids and venous valve dysfunction. This situation requires longer treatment and conditioning, and is accompanied by a higher risk of recurrence. The classification of phlebitis is related to the area of ​​inflammation and other symptoms, as follows: Grade 0: no clinical symptoms; Grade 1 (or 1+): The skin may develop erythema with or without pain, and the edema range is less than 2.5 cm. At this point, the inflamed area is relatively small; Grade 2 (or 2+): skin pallor or erythema, edema ranging from 2.5cm to 15cm. At this point, the inflamed area is relatively large; Grade 3 (or 3+): The skin is pale and transparent, the edema is greater than 15 cm, accompanied by mild to moderate pain and possible numbness. At this point, the inflamed area is already very large; Level 4: The skin is pale and transparent, tight and faded, with fluid exudation, the edema area is still greater than 15cm, the tissue becomes sunken after compression of the edema area, the circulatory system function is reduced, and there is moderate to severe pain. This is the most serious level of phlebitis, with a wide area of ​​inflammation and severe symptoms.

[0003] When phlebitis reaches level 3 or above, it needs to be treated in the hospital. According to clinical experience, the inflammation area of ​​most phlebitis patients is level 2 or below, that is, the edema range is within 15cm. For patients with phlebitis at level 2 or below, they are generally treated by external application of liquid medicine, usually twice a day, 20-30 minutes each time. The operation is relatively simple, but the frequency is too high and the time is relatively long. For most people, the working hours of the hospital are often the same as the working hours of the patient's own company. Going back and forth to the hospital many times a day is very inconvenient for themselves. In the long run, it is also a high expense. For medical resources, it may cause delays to the condition of other patients. Therefore, after the diagnosis, the doctor often prescribes the medicine and tells the patient how to use it, and the patient has more ways to treat himself at home.

[0004] The general method of home treatment for patients is: patients prepare a small basin, mix the medicine and a certain proportion of water in the small basin to ensure that the concentration of the medicine is within the appropriate range, then add hot water to another large basin, place the small basin containing the medicine inside the large basin for a hot water bath, so as to drive the medicine to about 40°C, then place a towel in the medicine, after it is completely wetted, take out the towel and twist it until the medicine does not drip, then apply the towel to the affected area, and wrap it tightly with plastic wrap to keep it moisturized and fixed. In order to prevent the temperature of the towel soaked in the medicine from losing during the external application process, a hot water bag needs to be used to press on the towel. After a single treatment, the towel needs to be cleaned and sterilized, and the small basin needs to be sealed with plastic wrap again to prevent bacteria in the air from entering the medicine and affecting the effect of the next use; It can be seen that although the operation is simple, the whole process is relatively cumbersome, and the patient cannot control the concentration of the medicine and the temperature of the medicine when it is heated. The fixation of the hot water bag also requires the patient to find a way to solve it by himself, and the disinfection of the towel is also worrying. Phlebitis occurs relatively more frequently in the limbs, and it is extremely inconvenient for such patients to perform the above operations. If the disease occurs in the upper limbs, the patient will cause pain due to the force of the arms when using both arms, and the condition will be aggravated. Even if phlebitis occurs in the lower limbs, the above operations will also cause inconvenience when walking, and there are safety hazards when carrying a large basin filled with hot water. For this reason, we propose a low-cost and easy-to-use Chinese medicine external application nursing device for preventing phlebitis for home use. Summary of the invention

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions 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. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example 1

[0018] See also Figure 1-4 The present invention provides a technical solution: a Chinese medicine external application nursing device for preventing phlebitis, comprising a support plate 10, handles 11 are installed on both sides of the support plate 10, a display controller 12 is installed on the support plate 10, the display controller 12 is a prior art, and the main structural parts are a programmed mainboard and an LED display screen, and also include: A wetting box 20, which is mounted on the support plate 10, and a weighing sensor 21 is disposed between the wetting box 20 and the support plate 10, and the weighing sensor 21 is electrically connected to the display controller 12, and a sealing cover 23 is mounted on the top of the wetting box 20 through a hinge 22, and a sealing ring 24 is disposed at the contact portion between the sealing cover 23 and the wetting box 20; The sealed cover 30 is installed at the bottom of the support plate 10. A fixed cylinder 31 is installed at the bottom of the sealed cover 30. A base 32 is installed in the fixed cylinder 31. A bearing 33 is sleeved on the base 32. The inner wall of the bearing 33 is fixed to the base 32, and the outer wall is fixed to the fixed cylinder 31. A disposable sterile gauze block 4, which is arranged inside the moistening box 20; A filter screen 5, the filter screen 5 is arranged inside the moistening box 20; The squeezing mechanism 6 is mounted on the support plate 10 and connected to the filter screen 5. The squeezing mechanism 6 drives the filter screen 5 to approach the sealing cover 23 to squeeze out the excess liquid medicine in the disposable sterile gauze block 4; A heating mechanism 7, which is mounted on the support plate 10 and connected to the wetting box 20, and heats the liquid medicine in the wetting box 20 to 40°C; The wet compress mechanism 8 is arranged on the support plate 10 and is partially located in the moistening box 20. The wet compress mechanism 8 adheres to the squeezed disposable sterile gauze piece 4 and continuously provides heat energy thereto.

[0019] The specification of the disposable sterile gauze piece 4 is 15cm×15cm, and the number of layers is 4-6 layers.

[0020] The disposable sterile gauze block 4 of this specification is suitable for patients with phlebitis below level 3, that is, it can be used by patients with phlebitis who treat themselves at home. The disposable sterile gauze block 4 with 4-6 layers can provide an appropriate thickness. Gauze of this thickness can not only ensure the permeability of the solution, but also prevent the solution from evaporating too quickly, thereby maintaining the moisturization of the wet compress area, and at the same time can absorb enough liquid medicine to maintain the wet compress effect for a longer time. At the same time, the disposable sterile gauze block 4 of this specification can be purchased directly on the market, which reduces the patient's use cost while ensuring hygiene.

[0021] The specification of the moistening box 20 is 20 cm×20 cm×10 cm, wherein 10 cm is the height.

[0022] When the liquid medicine in the moistening box 20 is heated to a temperature suitable for wet compressing the patient's body surface, that is, the time required to heat the liquid medicine to about 40° C. is shorter, and the smaller volume is also convenient for transportation, and the production cost is low.

[0023] The filter screen 5 has a specification of 18 cm×18 cm×2 mm, wherein 2 mm is the thickness, and is made of martensitic stainless steel.

[0024] The four sides of the filter 5 have the same spacing as the four sides corresponding to the inner wall of the wetting box 20. Martensitic stainless steel has high tensile strength and yield strength, high hardness, good corrosion resistance, and can be adsorbed by magnets. These characteristics give it a long service life. At the same time, it can be attracted and fixed by the magnet block 64 mentioned later, and move synchronously with the magnet block 64. After using it for a period of time, it is also convenient to disassemble and clean it.

[0025] The squeezing mechanism 6 includes a slide bar 61 installed through the four corners of the bottom of the wetting box 20, the slide bar 61 penetrates the bottom of the wetting box 20 and the support plate 10, one end of the slide bar 61 is located inside the wetting box 20, and the other end is located inside the closed cover 30. The connection part between the slide bar 61 and the wetting box 20 is a sliding connection, and also includes a cross 62 in the closed cover 30, and the four corners of the cross 62 are respectively fixed to one of the slide bars 61. An electric push rod 63 is installed at the bottom of the support plate 10, and the electric push rod 63 is electrically connected to the display controller 12. The top of the electric push rod 63 is fixed to the center of the cross 62. Magnet blocks 64 are fixed to the top of the slide bar 61, and the magnet blocks 64 correspond to the four corners of the bottom surface of the filter 5 respectively, and the connection between the slide bar 61 and the wetting box 20 and the support plate 10 are all sealed.

[0026] Patients perform corresponding operations according to the type of medicine: When the moistening medicine is a prepared solution, pour the appropriate amount of liquid medicine directly according to your own condition; When the wetted medicine is a powder and needs to be dissolved with a certain proportion of water, a part of the powder is placed in the wetting box 20 through packaging, and the weight of the powder is obtained under the action of the weighing sensor 21. Then the powder is taken out and a corresponding proportion of water is added to the wetting box 20. Similarly, the weight of the added water is sensed by the weighing sensor 21 and displayed by the display controller 12. After the amount of water is appropriate, the powder is added to ensure that the concentration of the liquid medicine is within an appropriate range. The space between the sealing cover 30 and the supporting plate 10 is sealed, so as to prevent the sliding rod 61 from being in contact with the outside air for a long time and being contaminated by bacteria in the air.

[0027] The heating mechanism 7 includes a power supply 71 installed at the bottom of the support plate 10. The power supply 71 is electrically connected to the display controller 12. An electric heating tube 72 is installed on the power supply 71. The electric heating tube 72 passes through the support plate 10 and the bottom of the wetting box 20, and is distributed in an S shape inside the wetting box 20, and is located between the bottom of the wetting box 20 and the filter 5.

[0028] The wet compress mechanism 8 includes an electric heating plate 81 arranged on the wetting box 20, the bottom surface of the electric heating plate 81 is coated with a plastic layer, and the thickness of the plastic layer is not less than 1 mm, and a Velcro 82 with adhesive backing is pasted on the bottom surface of the electric heating plate 81. A group of elastic bandages 83 are arranged on both sides of the electric heating plate 81, and conventional Velcro 84 is arranged on the elastic bandages 83.

[0029] The plastic layer can ensure that the adhesive Velcro 82 is firmly attached to the electric heating plate 81. At the same time, the adhesive Velcro 82 can be replaced after being used for a period of time. Since the adhesive Velcro 82 will come into contact with the outside world during each treatment, regular replacement has a positive effect on the efficacy of the medicine in the wetting box 20.

[0030] The specification of the adhesive-backed Velcro 82 is 10 cm×10 cm, and it is an injection-molded hook-type Velcro, and the thickness of the hook surface part is 1-2 mm.

[0031] Due to the limitation of specifications, when the disposable sterile gauze block 4 approaches the adhesive Velcro 82 in the wetting box 20, the adhesive Velcro 82 always completely overlaps with the disposable sterile gauze block 4, which can prevent the adhesive Velcro 82 from being partially dislocated after being attached to the disposable sterile gauze block 4, and the adhesive Velcro 82 part directly contacts the patient's skin and causes discomfort. The 1-2mm hook surface can stick the disposable sterile gauze block 4, and its fiber hook cannot completely penetrate the multi-layer gauze structure, thereby ensuring the patient's comfort during external application.

[0032] The moistening box 20 and the sealing cover 23 are provided with a buckle body 90 and a buckle ring 91 respectively.

[0033] It can also be a push-type buckle, which is a mature product on the market, and its main purpose is to be able to be operated with one hand.

[0034] It should be noted that in the present device, the liquid medicine in the wetting box 20 is placed at most 80% of its volume. On the one hand, it can be heated faster, and on the other hand, it can ensure that the disposable sterile gauze piece 4 will not come into contact with the liquid medicine in the wetting box 20 after being squeezed.

[0035] The working principle is as follows: under the action of the weighing sensor 21, the patient prepares a suitable concentration of liquid medicine by himself, pours a suitable amount of liquid medicine into the moistening box 20, places the disposable sterile gauze piece 4 in the moistening box 20, and then wraps it with the handle 11 through the elastic bandage 83. The handle 11 can be provided with a Velcro corresponding to the conventional Velcro 84 on the elastic bandage 83 for easy fixation, suspends the electric heating plate 81 above the moistening box 20, and then drives the sealing cover 23 to seal the moistening box 20 through the buckle body 90 and the buckle ring 91, and displays the controller 1. The electric heating tube 72 is turned on to heat the liquid medicine. Then the patient holds the handle 11 on one side of the support plate 10 and shakes it back and forth. Under the action of the base 32, the bearing 33 and the fixing cylinder 31, this process can be operated with one hand with a small force. The support plate 10 drives the liquid medicine to shake back and forth through the moistening box 20. While the liquid medicine is being shaken, the disposable sterile gauze piece 4 can also be in more sufficient contact with the liquid medicine. After being heated to about 40° C., the electric heating tube 72 stops working. The inside of the moistening box 20 can also be kept warm as required. When the patient needs external application, the electric push rod 63 is turned on through the display controller 12, and the electric push rod 63 drives the slide bar 61 and the magnet block 64 at the top of the slide bar 61 to move upward through the cross 62, and the magnet block 64 drives the filter screen 5 to move upward synchronously, and the filter screen 5 drives the disposable sterile gauze block 4 to approach the electric heating plate 81. Under the obstruction of the closed cover 23, the excess liquid medicine in the disposable sterile gauze block 4 is squeezed out by the filter screen 5 and falls back into the wetting box 20 through the filter screen 5. Under this squeezing, the adhesive Velcro 82 on the electric heating plate 81 is simultaneously pasted to the disposable sterile gauze block 4 to prevent the disposable sterile gauze block 4 from being immersed in the liquid medicine again, and then the squeezing mechanism 6 is reset, and the filter screen 5 is synchronously reset under the action of the magnet block 64; At this time, the patient removes the restriction between the sealed cover 23 and the wetting box 20, removes the electric heating plate 81 through the elastic bandage 83, and closes the sealed cover 23 again to prevent the liquid medicine in the wetting box 20 from being contaminated by bacteria, and at the same time prevent the evaporation of the liquid medicine from causing changes in its concentration. Then, the electric heating plate 81 is fixed to the affected area through conventional Velcro 84 and elastic bandage 83, so that the disposable sterile gauze block 4 completely covers the affected area, and then the electric heating plate 81 is turned on to prevent the disposable sterile gauze block 4 from losing heat too quickly. The above is a single complete external application process. When used next time, only the disposable sterile gauze block 4 needs to be replaced, and then the above operation can be repeated.

[0036] It should be noted that the device is small in size, and most of the required parts can be purchased directly on the market, and the parts are sold at a low price. The cost of producing the device is low, and the patient does not need to move drastically during the entire process. After purchasing the equipment, the total cost for a single use is the cost of the medicine + a single disposable sterile gauze block 4 + electricity, among which the electricity cost is almost negligible, and the cost of the medicine is a necessary expense. The market price of a disposable sterile gauze block 4 of this specification is 1.3-2 yuan per piece. That is, under the premise of ensuring a certain degree of hygiene and safety, the device is simple to operate, easy to use, low in production cost, and low in single-use cost, which is more suitable for patients who require long-term treatment and have a high recurrence rate.

[0037] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
