Description

Technical Field

[0001] The present invention relates to the field of medical devices, and in particular to an auxiliary device for relieving pain caused by intravenous infusion of irritating liquid medicine. Background Art

[0002] Potassium is an indispensable constant substance in the human body. Most of it exists in each cell of the human body. It can form a coordinated effect with the sodium outside the cell to keep the acid-base and water balance in the blood and body fluids of the human body. Once the human body lacks potassium, it will cause general weakness, fatigue, dizziness, vomiting, and arrhythmia. If the potassium deficiency is severe, it will lead to respiratory failure and even death. Currently, many scenarios can cause potassium deficiency in the human body, such as gastrointestinal obstruction, coma, or long-term fasting after surgery, and severe diarrhea, vomiting, and heavy sweating, which lead to excessive potassium excretion in the body, and the transfer of potassium from extracellular to intracellular.

[0003] Therefore, when a patient is deficient in potassium, potassium supplementation is required in a timely manner. Potassium supplementation is usually taken orally, but for patients who cannot eat through the digestive tract, potassium can only be supplemented by potassium infusion. It is well known that intravenous infusion of potassium chloride will cause excessive potassium ion content in the local vein and stimulate nerve cells to produce strong pain, which is difficult for many adults to endure, and even more painful for children. In addition, potassium infusion is not like injection or blood drawing, which is only a short-term pain, but lasts throughout the potassium infusion period. Therefore, it is necessary to design a device that can relieve the patient's pain during potassium infusion. Summary of the invention

[0004] The present invention is intended to provide an auxiliary device for relieving pain caused by intravenous infusion of irritating liquid medicine, so as to relieve the pain felt by patients during infusion of irritating liquid medicine.

[0005] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: an auxiliary device for relieving the pain of intravenous infusion of irritating liquid medicine, comprising a heatable restraint belt and a medicine bag filled with medicine, one end of the medicine bag is open, and the side of the medicine bag close to the restraint belt is made of waterproof material; the restraint belt is provided with a fixing portion, and the restraint belt is provided with a clamping mechanism for detachably connecting the medicine bag, the clamping mechanism includes two clamping portions that respectively clamp the two ends of the medicine bag, the clamping portion includes a clamping rod, and the two ends of the clamping rod are respectively provided with connecting shafts, the connecting shaft vertically penetrates the restraint belt and is slidably connected to the restraint belt, the end of the connecting shaft extending out of the restraint belt is provided with a limiting portion, and the restraint belt is provided with a receiving groove for accommodating the clamping rod.

[0006] Preferably, as an improvement, a side edge of the restraint belt is provided with an avoidance notch.

[0007] Preferably, as an improvement, the limiting portion includes a limiting cap arranged on the connecting shaft, a spring is sleeved on the connecting shaft, and two ends of the spring are respectively connected to the limiting cap and the restraining belt.

[0008] Preferably, as an improvement, the limiting portion includes a connecting piece for rotational movement with the connecting shaft, two ends of the connecting piece are respectively connected to the ends of the two connecting shafts, and the restraining belt is provided with a hanging piece for hanging the connecting piece.

[0009] Preferably, as an improvement, the medicine bag is provided with a scraping mechanism for scraping the medicine evenly.

[0010] Preferably, as an improvement, the scraping mechanism includes a holding member and a sliding shaft sliding on the medicine bag, the sliding shaft is provided with a scraping plate, the scraping plate is located in the medicine bag, the ends of the sliding shaft extend out of both sides of the medicine bag, the holding member is horizontally and vertically slidably connected to the restraining belt, the restraining belt is provided with a movable groove for the holding member to slide, one end of the holding member is detachably connected to the end of the sliding shaft, and the other end of the holding member extends out of the movable groove.

[0011] Preferably, as an improvement, the drug bag is a hexagonal structure, the two side surfaces of the drug bag adjacent to the opening are elastic sealing strips, and the middle of the elastic sealing strip is provided with a hole for the sliding shaft to slide.

[0012] Preferably, as an improvement, comb grooves and balls are equidistantly provided on both long sides of the scraper plate, and the balls are located on both sides of the comb grooves.

[0013] Preferably, as an improvement, the width of the movable groove is greater than the width of the holding member.

[0014] Preferably, as an improvement, the restraining belt is provided with a connecting belt for connecting two side edges of the avoidance slot.

[0015] The principles and advantages of this solution are as follows:

[0016] When patients are infusing potassium chloride, they feel strong pain around the infusion site. At the same time, since potassium supplementation is usually taken orally, and intravenous infusion is only performed in extremely special circumstances, there is currently no effective way to relieve potassium infusion pain. At present, medical staff will recommend that patients or their families massage or apply hot compresses around the infusion site to relieve pain, but the infusion time is usually long, and long-term massage will make the hands more sore, and the relief effect is also very limited; there are many ways to apply hot compresses, such as using hot towels, and those with better conditions can use hot compress pads, but the relief effect is also relatively limited. There are hot compress pads on the market that have both massage and hot compress functions, but due to the need for massage functions and the relatively large and complex structure, it is inconvenient to install on the arm. At the same time, the massage method is not applicable, which can easily affect the infusion needle and cause other injuries. The most important thing is that for patients who are more sensitive to pain, the relief effect is limited.

[0017] The applicant discovered in his work that aloe vera gel and fresh aloe vera pieces have a good effect in relieving the pain caused by potassium infusion. Therefore, based on this discovery, the applicant designed this solution, which has the following effects:

[0018] 1. This scheme can select different structures according to the different pain levels of the patients. If the pain is relatively mild, only the binding belt with heating function can be used to accelerate blood flow through hot compress, so that the local excessive potassium ions can flow quickly with the blood, thereby reducing the local pain of the patient. If the patient's pain is strong, a drug bag filled with drug fillers can be installed on the binding belt, so that the patient's pain can be greatly reduced under the dual effects of hot compress and drug compress.

[0019] 2. In this solution, the clamping rod used to clamp the medicine bag slides up and down through the connecting shaft, and a receiving groove for accommodating the clamping rod is opened on the restraint belt. In this way, when only the restraint belt is used without clamping the medicine bag, when the restraint belt is tied to the patient's arm, there is no need to cooperate with the additional action. The clamping rod is automatically retracted into the receiving groove to avoid the clamping rod causing pressure on the patient's skin and discomfort.

[0020] 3. A scraping mechanism is designed in this scheme, through which this scheme can achieve three effects at the same time: 1. After using for a period of time, the medicine on the side close to the patient's skin gradually becomes ineffective, while the other side of the medicine bag is made of waterproof material, and the liquid medicine in the medicine filler cannot seep out, so it cannot be used by turning it over. Therefore, in this scheme, the medicine filler on the upper side of the medicine bag can be turned down by pulling the scraping plate, thereby extending the medicinal time of the medicine bag. 2. At the same time, during the hot compress + medicine compress process, if the patient still feels slight pain, the scraping plate can be tilted and pulled so that the ball on the side of the scraping plate is pressed and contacted with the skin to play a massage role. At this time, this scheme achieves the triple effects of hot compress, medicine compress and massage at the same time, greatly relieving the patient's pain. 3. After the medicine filler is loaded into the medicine bag, the medicine filler tends to accumulate in one place of the medicine bag. At this time, after installing it on the restraint belt, the scraping plate can be moved back and forth in the medicine bag to evenly disperse the accumulated medicine fillers in various places of the medicine bag.

[0021] In summary, this solution has a simple structure, small size, easy use, low cost, and can achieve the triple effects of hot compress, medicinal compress and massage at the same time. It has excellent pain relief ability and has a good market prospect. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following is further described in detail through specific implementation methods:

[0032] The figure marks in the drawings of the specification include: restraint belt 1, avoidance slot 2, connecting belt 3, fixing part 4, clamping rod 5, connecting shaft 6, limiting cap 7, spring 8, accommodating groove 9, medicine bag 10, sliding shaft 11, holding member 12, push rod 13, scraping plate 14, combing groove 15, movable groove 16, clamping piece 17.

[0033] The embodiment is basically as shown in the attached Figure 1-4 As shown: an auxiliary device for relieving pain caused by intravenous infusion of irritating liquid medicine, comprising a restraining belt 1 and a medicine bag 10 for filling medicine, the medicine bag can be filled with medicines with analgesic effects such as aloe vera powder and aloe vera gel, one end of the medicine bag 10 is open for filling medicine. The side of the medicine bag 10 close to the restraining belt 1 is made of waterproof material to prevent water stains and medicine stains in the medicine from contaminating the restraining belt 1.

[0034] The restraint belt 1 is provided with a heating material, and the heating material can be a heating film made of carbon-based material, metal foil or conductive polymer. The heating material is soft and can be bent and folded at will, and is not easy to be damaged, so the restraint belt 1 can be better wrapped around the patient's arm. The outer surface of the restraint belt 1 is equipped with a power supply unit and a functional operation unit. The heating film is connected to the power supply, and the heating film is heated by conduction. The functional operation unit includes a switch for controlling the operation of the power supply, and a component for adjusting the size of the heating temperature. This is a prior art and will not be elaborated here. Figure 1As shown, the restraint belt 1 is provided with a fixing part 4, and the fixing part 4 includes a snap-on buckle, a Velcro, etc. respectively installed at both ends of the restraint belt 1, and is used to fix the restraint belt 1 to the patient's infusion site. An avoidance slot 2 is provided on one side of the restraint belt 1 close to the infusion site, so that the patient's infusion site can be avoided to relieve the surrounding parts. At the same time, a connecting belt 3 is sewn on one side of the avoidance slot 2, and a Velcro is set between the free end of the connecting belt 3 and the other side of the avoidance slot 2. The two sides of the avoidance slot 2 are connected by the connecting belt 3, so that the restraint belt 1 located at the avoidance slot 2 can better fit the patient's skin, thereby achieving a better relief effect.

[0035] like Figure 2 , Figure 3 As shown, the restraint 1 is also provided with a clamping mechanism for detachably connecting the drug bag 10, the clamping mechanism includes two clamping parts respectively clamping the two ends of the drug bag 10, each clamping part includes a clamping rod 5, the two ends of the clamping rod 5 are respectively fixedly connected to a connecting shaft 6, the connecting shaft 6 vertically passes through the restraint 1 upward, and is slidably connected to the through hole on the restraint 1, and the end of the connecting shaft 6 extending out of the restraint 1 is provided with a limiting part. In one embodiment, the limiting part includes a limiting cap 7 integrally formed or welded to the top of the connecting shaft 6, and a spring 8 is sleeved on the connecting shaft 6, and the two ends of the spring 8 are respectively connected to the limiting cap 7 and the restraint 1. With this design, when installing the drug bag 10, the clamping rod 5 is pulled to put the end of the drug bag 10 into the clamping rod 5 and the clamping rod 5 is loosened, and the drug bag 10 is automatically clamped on the restraint 1 under the action of the spring 8, and the operation is simple.

[0036] In another embodiment, the limiting portion includes a connector for rotating with the top of the connecting shaft 6, and the two ends of the connector are respectively connected to the ends of the two connecting shafts 6. The connector can be a rope, a chain, etc., or a hard plastic strip, a metal strip, etc. The latter is connected in a hinged manner. A hanging piece for hanging the connector is fixedly mounted on the upper surface of the restraint belt 1. When installing the drug bag 10, the two ends of the drug bag 10 are respectively placed in the clamping rod 5, and then the connector is pulled and hung on the hanging piece, so that the clamping rod 5 is tightened upward to clamp the drug bag.

[0037] The restraint belt 1 is provided with a receiving groove 9 for accommodating the clamping rod 5. By providing the receiving groove 9, when only the restraint belt 1 is used without clamping the medicine bag 10, when the restraint belt 1 is tied to the patient's arm, the clamping rod 5 is automatically received into the receiving groove 9 to avoid the clamping rod 5 causing pressure on the patient's skin and discomfort.

[0038] When used specifically:

[0039] Only use the strap 1: tie the strap 1 around the patient's arm and place the avoidance slot 2 at the patient's infusion site to prevent the strap 1 from pressing on the infusion site, and activate the heating function to apply heat to the area around the infusion site to accelerate blood flow and allow the locally excessive potassium ions to flow quickly with the blood, thereby reducing the patient's local pain.

[0040] Using the restraint belt 1 and the medicine bag 10: Figure 4 As shown, when the patient's pain is severe and hot compress cannot effectively relieve it, a drug filler with the ability to relieve pain or analgesia, such as aloe vera powder or aloe vera gel, is loaded into the drug bag 10, and then the two ends of the drug bag 10 are respectively clamped on the clamping rods 5 at the two ends of the restraint belt 1 and fixed. The drug filler in the drug bag 10 is flattened with an additional tool and tied to the patient's arm together with the restraint belt 1, and the heating function is activated. In this way, hot compress and drug application are performed at the same time, which is more effective in relieving the patient's pain.

[0041] Embodiment 2:

[0042] like Figure 5-Figure 9 As shown, the medicine bag 10 is a hexagonal structure, and the two sides of the medicine bag 10 near the opening are elastic sealing strips, and the elastic sealing strips can be made of elastic cloth strips. There are holes in the middle of the two elastic sealing strips, and the positions of the two holes are opposite. The medicine bag 10 is also provided with a scraping mechanism for scraping the medicine evenly, and the scraping mechanism includes a sliding shaft 11 slidably connected to the medicine bag 10, and the two ends of the sliding shaft 11 pass through holes respectively. A scraping plate 14 is fixedly installed on the sliding shaft 11 located in the medicine bag 10. Since the scraping plate is a disposable component, the scraping plate 14 is preferably made of plastic material, which has both toughness and hardness and low cost. In this solution, by designing the two sides of the medicine bag 10 as elastic sealing strips, when the sliding shaft 11 is operated in the medicine bag 10, on the one hand, it can slide back and forth by utilizing the elasticity of the elastic sealing strip, and on the other hand, it can ensure that the medicine in the medicine bag 10 will not leak out during the sliding process.

[0043] like Figure 6As shown, both ends of the sliding shaft 11 extending out of the drug bag 10 are detachably connected with a holding piece 12. The detachable connection design allows the holding piece to be reused with the restraint belt. Specifically, a clamping piece 17 with a certain deformation ability is fixedly installed at the lower end of the holding piece 12. The cross section of the clamping piece 17 is an arc-shaped structure. When the clamping piece 17 is in a natural state, its inner diameter is smaller than the diameter of the sliding shaft 11; in another embodiment, a strip hole is opened at the lower end of the holding piece, and the end of the sliding shaft is a rectangular structure with a size slightly smaller than the strip hole. In this way, the holding piece can be quickly sleeved on the sliding shaft. At the same time, during the pulling process, the sliding shaft 11 can rotate with the rotation of the holding piece 12 and the two are not easy to separate during the movement process. The holding piece 12 is in a vertical state after being clamped and fixed with the scraper 14. The distance between the connection points of the left and right ends of the holding member 12 and the sliding shaft 11 is greater than the distance between the two holes, and the length of the scraping plate 14 is less than the width of the drug bag, so that the sliding shaft 11 can have sliding space along its axial direction. In this way, the scraping plate 14 can change its lateral movement path each time it slides during the back and forth scraping process, so as to comb the drug filling more quickly and effectively. The holding member 12 vertically penetrates the restraining belt 1 upward and is connected to the restraining belt 1 in a lateral sliding manner. The top ends of the two holding members 12 are fixedly connected to the two ends of the push rod 13, and the sliding shaft 11 is driven to slide by pushing the push rod 13. A movable groove 16 for the holding member 12 to slide is provided on the restraint belt 1 along the sliding direction of the holding member 12. A magnet for magnetically fixing the holding member 12 is provided at the position corresponding to the hole of the movable groove 16. With this design, when the scraper plate is not used, the holding member 12 is vertically adsorbed on the magnet of the movable groove 16. At this time, the scraper plate 14 and the medicine bag / arm remain parallel to each other to prevent the side of the scraper plate 14 from hitting the patient. At the same time, when only the restraint belt is used, when the restraint belt is tied to the arm, the holding member 12 can automatically (or manually) move upward until its bottom is located in the movable groove and is magnetically attracted to the magnet. On the one hand, the holding member 12 can be always connected to the restraint belt for repeated use, and on the other hand, the holding member will not scratch the patient's skin.

[0044] like Fig. 9 As shown, combing grooves 15 are equidistantly arranged on at least one long side of the scraping plate 14. By setting the combing grooves 15, when the scraping plate 14 is pulled back and forth, it is more conducive to the movement and flow of the medicine in the bag, so that the medicine and the medicine particles are laid more evenly; in addition, more importantly, through this design, the patient can push the sliding shaft 11 to move back and forth in the medicine bag 10 through the holding member 12 according to his or her own pain situation, and the pressing force of the scraping plate 14 on the patient's skin can play a massage role, accelerate the blood flow at the infusion site, and thus further improve the pain relief effect. At the same time, balls are equidistantly installed on both long sides of the scraping plate 14, so as to increase the local contact area between the scraping plate 14 and the patient's skin, thereby improving the patient's comfort during the scraping of the medicine by the scraping plate 14.

[0045] During specific use: after loading drug fillers, such as aloe vera crumbs, aloe vera gel and other analgesic fillers into the drug bag 10, the drug fillers tend to accumulate in one place of the drug bag 10. At this time, first clamp the two ends of the drug bag 10 on the clamping rods 5 at the two ends of the restraining belt 1 and fix them, then turn the drug bag 10 upward and clamp the clamping pieces of the pulling member 12 at the two ends of the sliding shaft 11, tilt the push rod 13 to tilt the scraper 14 to a certain angle, and move back and forth in the drug bag 10 to evenly disperse the accumulated drug fillers in various places of the drug bag 10. After using it for a period of time, the drug on the side close to the patient's skin gradually loses its effectiveness, while the other side of the drug bag 10 is made of waterproof material, and the liquid of the drug filler cannot seep out, so it cannot be used by turning it over. Therefore, in this solution, the drug filler on the upper side of the drug bag 10 can be turned over by pulling the scraper 14, thereby extending the medicinal use time of the drug bag 10. At the same time, during use, the patient can also tilt and pull the scraper 14 so that the balls on the side of the scraper 14 press against the skin to achieve a massage effect, thereby accelerating blood flow at the infusion site and further improving the pain relief effect.

[0046] The above is only an embodiment of the present invention, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
