Description

Technical Field

[0001] This invention relates to the field of medical care products technology, and in particular to a multi-site subcutaneous infusion auxiliary device. Background Technology

[0002] Patients who fall into a coma in hospitals, in the wild, or at disaster sites are mostly suffering from traumatic shock, hypoglycemia, electrolyte imbalance, hyponatremia, or dehydration due to high temperature. In such cases, it is necessary to provide emergency subcutaneous fluid resuscitation to treat them. For example, subcutaneous infusion of 2.5% glucose + 0.45% NaCl + 100 IU / L hyaluronidase can be used to treat traumatic shock; subcutaneous infusion of 3.5% glucose + 1.5 μg / mL glucagon can be used to treat hypoglycemia; and subcutaneous infusion of 1.5% glucose + 0.9% NaCl + 0.2% potassium chloride can be used to treat dehydration due to high temperature.

[0003] Traditional subcutaneous fluid resuscitation is typically performed in the tensor fasciae latae region of the abdomen or anterolateral thigh. Each subcutaneous puncture should be spaced approximately 3.5 cm apart to prevent multiple puncture points from being too concentrated, which could lead to local bleeding, infection, inflammation, pain, hematoma, nerve and vascular damage, etc. However, currently, the location of subcutaneous fluid resuscitation puncture points is mostly determined by medical staff through visual estimation. This method can lead to positioning errors, and when there are many subcutaneous puncture points, there is also a possibility that the same puncture point may be located repeatedly, resulting in repeated punctures and poor operational reliability.

[0004] In response, the inventor of this patent, combining clinical experience, deeply considered the problems encountered in clinical work, reviewed a large amount of scientific research data and literature, and gradually conceived and designed this application through a novelty search to solve the relevant technical problems. Summary of the Invention

[0005] This invention aims to at least partially solve one of the technical problems in related technologies. Therefore, the object of this invention is to provide a multi-site subcutaneous infusion support device.

[0006] To achieve one of the above objectives, a multi-site subcutaneous infusion auxiliary device according to an embodiment of the present invention includes a multi-site subcutaneous infusion positioning patch adapted to be adhered to the tensor fasciae latae region of the abdomen or anterolateral thigh:

[0007] The multi-site subcutaneous infusion positioning patch has multiple subcutaneous infusion positioning holes evenly distributed on its upper surface near its periphery, extending to its lower surface.

[0008] In addition, the multi-site subcutaneous infusion auxiliary device according to the above embodiments of the present invention may also have the following additional technical features:

[0009] According to one embodiment of the present invention, the multi-site subcutaneous infusion positioning patch has a certain layer thickness and is made of butene copolymer, gelatin, polypropylene glycol and ethylene-vinyl acetate copolymer to allow for plastic deformation.

[0010] According to one embodiment of the present invention, it further includes a plurality of sterile hemostatic cotton balls;

[0011] Multiple sterile hemostatic cotton balls are correspondingly embedded in multiple subcutaneous infusion positioning holes to fix them together with the multi-site subcutaneous infusion positioning patch.

[0012] According to one embodiment of the present invention, it further includes a bottom protective film for isolating and protecting the bottom surface of the multi-site subcutaneous infusion positioning patch;

[0013] The size of the bottom protective film is adapted to the size of the multi-site subcutaneous infusion positioning patch, and it is peelably attached to the bottom surface of the multi-site subcutaneous infusion positioning patch. The outer edge of the bottom protective film is provided with a tear loop A.

[0014] According to one embodiment of the present invention, it further includes a plurality of top protective films for correspondingly covering the plurality of said subcutaneous infusion positioning holes to isolate and protect them respectively;

[0015] The outer diameter of each of the multiple top protective films is slightly larger than the inner diameter of each of the multiple subcutaneous infusion positioning holes, and each of the films can be peeled off and adhered to the upper surface of the subcutaneous infusion positioning patch at the multiple sites to seal and cover the multiple subcutaneous infusion positioning holes, and each of the top protective films is provided with a tear loop B on its outer edge.

[0016] According to one embodiment of the present invention, the hole distance between any two adjacent subcutaneous infusion positioning holes is D, wherein D = 2.0cm-4.0cm.

[0017] According to one embodiment of the present invention, it further includes a positioning seat for inserting and positioning a subcutaneous infusion syringe;

[0018] The size of the positioning seat is adapted to the size of the multi-site subcutaneous infusion positioning patch, and is stacked and fixed on the upper surface of the multi-site subcutaneous infusion positioning patch. Multiple positioning slots that penetrate to the lower surface of the upper surface are evenly provided.

[0019] The plurality of positioning slots are located directly above the plurality of subcutaneous infusion positioning holes, and the inner diameter of the plurality of positioning slots is larger than the inner diameter of the plurality of subcutaneous infusion positioning holes, and is slightly larger than the outer diameter of the syringe barrel of the subcutaneous infusion syringe.

[0020] According to one embodiment of the present invention, the outer diameter of the plurality of top protective films is slightly larger than the inner diameter of the plurality of positioning slots, and all of them can be peeled off and adhered to the upper surface of the subcutaneous infusion positioning patch at the multiple sites, so as to correspondingly seal and cover the plurality of positioning slots.

[0021] According to one embodiment of the present invention, the positioning seat is made of transparent plastic material, and the vertical height of the positioning seat is H, wherein H = 2.0cm-4.0cm.

[0022] According to one embodiment of the present invention, it further includes a syringe for subcutaneous infusion;

[0023] The subcutaneous infusion syringe includes a syringe barrel, a piston-type plunger, and a puncture needle for assembling the subcutaneous infusion solution;

[0024] The syringe barrel has a Luer connector at the front end and an open rear end; the piston-type push rod has a sealing piston at the front end, and the outer wall of the sealing piston at the front end has a soft rubber sealing ring that tightly abuts against the inner wall of the syringe barrel; the outer wall of the rear end of the sealing piston has an external thread; the inner wall of the syringe barrel has an internal thread that meshes with the external thread; the piston-type push rod has a handle at the rear end, so that the sealing piston can be pushed to move along the length of the syringe barrel when rotated; the rear end of the puncture needle is detachably inserted into the Luer connector.

[0025] The beneficial effects of this invention are:

[0026] Firstly, the multi-site subcutaneous infusion auxiliary device provided in this application, in its specific implementation, involves pre-disinfecting the patient's abdomen or the tensor fasciae latae region of the anterolateral thigh with iodine or similar disinfectant. Then, the multi-site subcutaneous infusion positioning patch described in this application is adhered to the skin surface of the patient's abdomen or the tensor fasciae latae region of the anterolateral thigh. Subsequently, puncture needles are inserted into the multiple subcutaneous infusion positioning holes, regardless of their orientation, to infuse the required medication into the patient's skin via a connected subcutaneous infusion syringe. The pre-defined positions and distances of the subcutaneous infusion positioning holes prevent the multiple puncture points from becoming too concentrated, thus reducing the risk of local bleeding, infection, inflammation, pain, hematoma, nerve and vascular damage at the subcutaneous puncture site. This ensures the safety and reliability of this application.

[0027] Secondly, since the location and distance of the subcutaneous infusion positioning hole are predetermined, compared with the related operations in the background technology, medical staff do not need to estimate and determine it by visual means, which can greatly reduce the physical exertion of medical staff. Moreover, it is less likely to cause repeated punctures due to the same puncture point being located repeatedly. This is because after a subcutaneous infusion positioning hole is used, it can be marked on the side for differentiation, which makes the operation of this application highly reliable.

[0028] Thirdly, because the multi-site subcutaneous infusion positioning patch has a certain thickness and is made of butene copolymer, gelatin, polypropylene glycol and ethylene-vinyl acetate copolymer, it is malleable and deformable. As a result, it is soft and clay-like, and can be molded into any desired shape. It also has self-adhesive properties. When it is adhered to the skin surface of the patient's abdomen or the anterolateral tensor fasciae latae region, even if the skin of the relevant adhesion area is uneven, it will automatically shape itself when the multi-site subcutaneous infusion positioning patch is pressed with a little force, so as to automatically fill the uneven parts of the skin surface of the patient's abdomen or the anterolateral tensor fasciae latae region. This achieves a more stable adhesion to the skin surface of the patient's abdomen or the anterolateral tensor fasciae latae region, making the use of this application more reliable.

[0029] Fourthly, in actual use of this application, the puncture needle is inserted directly through the sterile hemostatic cotton ball to the subcutaneous tissue of the relevant patient for subcutaneous fluid resuscitation. Then, the sterile hemostatic cotton ball can be used to isolate the relevant puncture site and absorb any oozing blood as much as possible to avoid blood from the relevant puncture site splashing everywhere and causing cross-infection.

[0030] Fifthly, when the sterile hemostatic cotton ball at a certain location absorbs blood and turns red, it indicates that the relevant subcutaneous infusion positioning hole has been used. This allows the sterile hemostatic cotton ball to also serve as a marking tool, saving medical staff the trouble of marking it separately. This makes it less likely that the same puncture point will be repeatedly positioned, leading to repeated punctures.

[0031] Sixthly, in practical use of this application, by setting the positioning seat and opening multiple positioning slots, after the puncture needle of the subcutaneous infusion syringe is inserted into the subcutaneous tissue of the relevant patient through the subcutaneous infusion positioning hole at the required position, the lower half of the syringe barrel is fitted and stabilized by the positioning slot at the corresponding position, so that medical staff can operate it with one hand to inject the liquid into the subcutaneous tissue of the relevant patient for fluid replacement. Furthermore, especially when multiple subcutaneous infusion syringes are used in sequence, the lower halves of the corresponding syringe barrels can all be fitted and stabilized, allowing medical staff to free up their hands to operate each subcutaneous infusion syringe with one hand. Thus, the use of this application greatly facilitates medical staff.

[0032] Seventhly, after the medical staff inserts the puncture needle of the subcutaneous infusion syringe into the patient's subcutaneous tissue at a certain depth through the subcutaneous infusion positioning hole at the desired location, they can rotate the handle to push the sealing piston along the length of the syringe barrel, so as to slowly infuse the required medication into the patient's subcutaneous tissue. This process eliminates the need for the medical staff to perform pressing operations, making medication infusion less strenuous. Because the rear end of the sealing piston is threaded to the inner wall of the syringe barrel, the sealing piston is not prone to rebounding outward, making it less likely for the medication to flow back into the patient's subcutaneous tissue. Because the outer wall of the front end of the sealing piston is provided with a soft rubber sealing ring A that tightly abuts against the inner wall of the syringe barrel, even if the rear end of the sealing piston is threaded to the inner wall of the syringe barrel, the medication pre-filled in the syringe barrel is not prone to overflowing through the rear end of the sealing piston, making the subcutaneous infusion syringe of this application highly reliable in use.

[0033] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0071] The multi-site subcutaneous infusion auxiliary device 1000 of the present invention will now be described in detail with reference to the accompanying drawings.

[0072] Example 1

[0073] Reference Figure 1 , Figure 2 and Figure 5 As shown;

[0074] The multi-site subcutaneous infusion auxiliary device 1000 provided in this embodiment of the invention includes a multi-site subcutaneous infusion positioning patch 10 adapted to be adhered to the tensor fasciae latae region of the abdomen or anterolateral thigh.

[0075] The multi-site subcutaneous infusion positioning patch 10 has multiple subcutaneous infusion positioning holes 101 that penetrate to its bottom surface evenly on its upper surface near its periphery.

[0076] Based on the above, it is clear that in specific implementation, this application is mainly used as a multi-site subcutaneous infusion auxiliary device 1000.

[0077] Specifically, when applying this application, the patient's abdomen or the anterolateral tensor fasciae latae area is disinfected with iodine solution beforehand. Then, the multi-site subcutaneous infusion positioning patch 10 described in this application is adhered to the skin surface of the patient's abdomen or the anterolateral tensor fasciae latae area. Subsequently, when subcutaneous fluid resuscitation is required for the patient, multi-site puncture is performed to administer subcutaneous fluid resuscitation treatment for traumatic shock, hypoglycemia, electrolyte imbalance, hyponatremia, or hyperthermic dehydration. Puncture needles can be inserted into the multiple subcutaneous infusion positioning holes 101 respectively to infuse the required medication into the relevant patient's subcutaneous tissue through the subcutaneous infusion syringe 60 connected to them. In this way, this application can be used easily.

[0078] Clearly, the use of this application will have the following technical effects:

[0079] On the one hand, the patient's abdomen or the anterolateral thigh tensor fasciae latae area is disinfected with iodine solution beforehand. Then, the multi-site subcutaneous infusion positioning patch 10 described in this application is adhered to the skin surface of the patient's abdomen or the anterolateral thigh tensor fasciae latae area. Then, puncture needles can be inserted into the multiple subcutaneous infusion positioning holes 101 in a front-to-back manner to infuse the required medication into the relevant patient subcutaneously through the subcutaneous infusion syringe 60 connected to them. For the relevant operation, the position and distance of the subcutaneous infusion positioning holes 101 are predetermined, so that the multiple puncture points are not too concentrated, so as not to cause problems such as local bleeding, infection and inflammation, pain and hematoma, nerve and blood vessel damage at the subcutaneous puncture site of the relevant patient due to the concentration of puncture points, making the use of this application safe and reliable.

[0080] On the other hand, since the position and distance of the subcutaneous infusion positioning hole 101 are predetermined, compared with the related operations in the background technology, medical staff do not need to estimate and determine by visual means, which can greatly reduce the physical exertion of medical staff. Moreover, it is less likely that the same puncture point will be repeatedly located, resulting in repeated punctures. This is because after a subcutaneous infusion positioning hole 101 is used, it can be marked on its side for differentiation, which makes the operation of this application highly reliable.

[0081] Furthermore, through the above-mentioned optimized design, the whole constituted by this application is highly practical and has a good effect in use.

[0082] Furthermore, in a specific implementation, according to one embodiment of the present invention, the multi-site subcutaneous infusion positioning patch 10 has a certain layer thickness and is made of butene copolymer, gelatin, polypropylene glycol and ethylene-vinyl acetate copolymer to allow for plastic deformation.

[0083] In this regard, it is clear that in the technical solution of this application, the multi-site subcutaneous infusion positioning patch 10 has a certain layer thickness and is made of butene copolymer, gelatin, polypropylene glycol and ethylene-vinyl acetate copolymer to make it malleable and deformable. This makes its texture soft and like clay, allowing it to be molded into any desired shape. It also has inherent adhesiveness. When it is adhered to the skin surface of the patient's abdomen or the anterolateral thigh tensor fasciae latae region, even if the skin in the relevant adhesion area is uneven, it will automatically shape itself when the multi-site subcutaneous infusion positioning patch 10 is pressed with slight force. This automatically fills in the uneven areas of the skin surface of the patient's abdomen or the anterolateral thigh tensor fasciae latae region, achieving a more stable adhesion to the skin surface of the patient's abdomen or the anterolateral thigh tensor fasciae latae region, making the application more reliable in use.

[0084] Furthermore, through the above-mentioned optimized design, the overall performance of this application can be effectively improved.

[0085] Preferably, in this technical solution, according to an embodiment of the present invention, this application further includes a plurality of sterile hemostatic cotton balls 20;

[0086] The sterile hemostatic cotton balls 20 are respectively embedded in the subcutaneous infusion positioning holes 101 so as to be fixed together with the multi-site subcutaneous infusion positioning patch 10.

[0087] In this regard, it is clear that in actual use of this application, the puncture needle is inserted directly into the subcutaneous tissue of the relevant patient through the sterile hemostatic cotton ball 20 to administer subcutaneous fluid replacement. Then, the moment the puncture needle is withdrawn, the sterile hemostatic cotton ball 20 can be used to isolate the relevant puncture site and absorb any oozing blood, so as to avoid blood from the relevant puncture site splashing everywhere and causing cross-infection.

[0088] Meanwhile, when the sterile hemostatic cotton ball 20 at a certain location absorbs blood and turns red, it indicates that the relevant subcutaneous infusion positioning hole 101 has been used, so that the sterile hemostatic cotton ball 20 can also serve as a marking function, saving medical staff from marking it separately, and making it less likely that the same puncture point will be repeatedly positioned, resulting in repeated punctures.

[0089] Furthermore, in a specific implementation, according to an embodiment of the present invention, this application also includes a bottom protective film 30 for isolating and protecting the bottom surface of the multi-site subcutaneous infusion positioning patch 10;

[0090] The bottom protective film 30 is adapted to the size of the multi-site subcutaneous infusion positioning patch 10 and can be peeled off and adhered to the bottom surface of the multi-site subcutaneous infusion positioning patch 10. The outer edge of the bottom protective film 30 is provided with a tear loop A301.

[0091] Therefore, before using this application, the bottom surface of the multi-site subcutaneous infusion positioning patch 10 is isolated and protected by the bottom protective film 30, which makes the bottom surface have good anti-pollution effect and is not easy to lose its adhesiveness. When using it, medical staff can easily tear off the bottom protective film 30 by pinching the tear loop A301, making the bottom protective film 30 convenient to use.

[0092] Furthermore, in a specific implementation, according to an embodiment of the present invention, this application also includes a plurality of top protective films 40 for correspondingly covering the plurality of subcutaneous infusion positioning holes 101 to isolate and protect them respectively;

[0093] The outer diameter of each of the multiple top protective films 40 is slightly larger than the inner diameter of each of the multiple subcutaneous infusion positioning holes 101, and each of them can be peeled off and adhered to the upper surface of the multi-site subcutaneous infusion positioning patch 10 to seal and cover the multiple subcutaneous infusion positioning holes 101, and each of the top protective films 40 is provided with a tear-off loop B401 on its outer edge.

[0094] Therefore, before using this application, the multiple top protective films 40 are used to seal and cover the multiple subcutaneous infusion positioning holes 101, making the multiple subcutaneous infusion positioning holes 101 less prone to contamination. When a certain subcutaneous infusion positioning hole 101 needs to be used, the tear loop B401 can be squeezed to tear off the top protective film 40 at the corresponding position. In this way, the corresponding subcutaneous infusion positioning hole 101 can be easily used to perform subcutaneous fluid resuscitation through subcutaneous puncture of the relevant patient.

[0095] In this regard, it can also be clearly stated that as long as the top protective film 40 is torn off at a certain position, it can also be clearly stated that the subcutaneous infusion positioning hole 101 at the corresponding position is being used or has been used, so as to better remind medical staff that the subcutaneous infusion positioning hole 101 at the corresponding position can no longer be reused.

[0096] Furthermore, in this technical solution, according to one embodiment of the present invention, the hole distance between any two adjacent subcutaneous infusion positioning holes 101 is D, where D = 2.0cm-4.0cm.

[0097] In a preferred embodiment, D is set to 3.5cm. That is, in actual application of this application, the hole distance D between each two adjacent subcutaneous infusion positioning holes 101 is set to 3.5cm, so that it is neither too far nor too close.

[0098] Furthermore, in a preferred embodiment of the present invention, the subcutaneous infusion positioning holes 101 are uniformly provided in 5-8 locations, preferably 6, so that the required medication can be infused into the subcutaneous tissue of the relevant patient without prior arrangement. For example, a subcutaneous infusion of 2.5% glucose + 0.45% NaCl + 100 IU / L hyaluronidase can be used to treat traumatic shock; a subcutaneous infusion of 3.5% glucose + 1.5 μg / mL glucagon can be used to treat hypoglycemia; and a subcutaneous infusion of 1.5% glucose + 0.9% NaCl + 0.2% potassium chloride can be used to treat hyperthermic dehydration. Each medication can be infused once or multiple times.

[0099] Example 2

[0100] Reference Figures 3 to 8 As shown;

[0101] Based on Embodiment 1, according to an embodiment of the present invention, this application further includes a positioning seat 50 for inserting and positioning the subcutaneous infusion syringe 60;

[0102] The size of the positioning seat 50 is adapted to the size of the multi-site subcutaneous infusion positioning patch 10, and is stacked and fixed on the upper surface of the multi-site subcutaneous infusion positioning patch 10. Multiple positioning slots 501 that penetrate to the lower surface of the upper surface are evenly provided.

[0103] Furthermore, the plurality of positioning slots 501 are located directly above the plurality of subcutaneous infusion positioning holes 101, and the inner diameter of the plurality of positioning slots 501 is larger than the inner diameter of the plurality of subcutaneous infusion positioning holes 101, and is slightly larger than the outer diameter of the syringe barrel 601 of the subcutaneous infusion syringe 60.

[0104] Therefore, it is clear that in actual use of this application, by setting the positioning seat 50 and opening multiple positioning slots 501, after the puncture needle 603 of the subcutaneous infusion syringe 60 is inserted into the subcutaneous tissue of the relevant patient through the subcutaneous infusion positioning hole 101 at the required position, the positioning slots 501 at the corresponding positions are used to fit and stabilize the lower half of the syringe barrel 601 of the subcutaneous infusion syringe 60, so that medical personnel can operate it with one hand to inject the liquid into the subcutaneous tissue of the relevant patient for fluid replacement. Specifically, refer to... Figure 6 As shown.

[0105] Based on this, especially when multiple subcutaneous infusion syringes 60 are used in sequence, the lower half of the corresponding multiple syringes 601 can be covered and stabilized, allowing medical staff to free up their hands to operate the multiple subcutaneous infusion syringes 60 used with one hand. In this way, the use of this application can greatly facilitate medical staff.

[0106] Furthermore, in this technical solution, according to an embodiment of the present invention, the outer diameter of the plurality of top protective films 40 is slightly larger than the inner diameter of the plurality of positioning slots 501, and all of them are peelable and adhered to the upper surface of the multi-site subcutaneous infusion positioning patch 10 to correspondingly seal and cover the plurality of positioning slots 501.

[0107] Thus, based on Embodiment 1, the multiple top protective films 40 are peelable and adhered to the upper surface of the multi-site subcutaneous infusion positioning patch 10 to correspondingly seal and cover the multiple positioning slots 501, making the multiple positioning slots 501 less susceptible to contamination before use.

[0108] When it is necessary to use a certain positioning slot 501 and the subcutaneous infusion positioning hole 101 located directly below it, the tear loop B401 can be squeezed to tear off the top protective film 40 at the corresponding position. In this way, the corresponding positioning slot 501 and the subcutaneous infusion positioning hole 101 located directly below it can be easily used to perform subcutaneous fluid resuscitation on the relevant patient through subcutaneous puncture.

[0109] Meanwhile, in this preferred embodiment of the present invention, the positioning seat 50 is made of transparent plastic material, and the vertical height of the positioning seat 50 is H, where H = 2.0cm-4.0cm.

[0110] Thus, by making the positioning seat 50 a transparent plastic material, medical personnel can easily observe the depth to which the puncture needle 603 of the subcutaneous infusion syringe 60 is inserted under the skin of the relevant patient. It also makes it easy for medical personnel to observe whether there is any abnormality such as severe bleeding from the puncture site on the skin surface of the relevant patient. Furthermore, when the vertical height H of the positioning seat 50 is 2.0cm-4.0cm, its vertical height is neither too high nor too low. After the puncture needle 603 of the subcutaneous infusion syringe 60 is inserted under the skin of the relevant patient, the positioning seat 50 can indeed stably support and hold the lower half of the syringe barrel 601 of the subcutaneous infusion syringe 60.

[0111] It should be added that, in specific implementation, comparison should be made with... Figures 6 to 8 As shown, the multi-site subcutaneous infusion auxiliary device 1000 provided according to an embodiment of the present invention also includes a dedicated subcutaneous infusion syringe 60 for use in conjunction with it;

[0112] The subcutaneous infusion syringe 60 includes a syringe 601 for holding a subcutaneous infusion solution, a piston rod 602, and a puncture needle 603.

[0113] The syringe 601 has a Luer connector 6011 at its front end and an open rear end; the piston-type push rod 602 has a sealing piston 6021 at its front end, and a soft rubber sealing ring A60211 that tightly abuts against the inner wall of the syringe 601 on the outer wall of the front end of the sealing piston 6021; the outer wall of the rear end of the sealing piston 6021 has an external thread 60212; the inner wall of the syringe 601 has an internal thread that meshes with the external thread 60212; the piston-type push rod 602 has a handle 6022 at its rear end, which can push the sealing piston 6021 to move along the length of the syringe 601 when rotated; the puncture needle 603 is detachably inserted into the Luer connector 6011 at its rear end.

[0114] Furthermore, in the preferred embodiment, when the handle 6022 is rotated one revolution, the sealing piston 6021 is driven to move along the length of the syringe 601 to inject 1 ml of medication into the patient's subcutaneous tissue.

[0115] Therefore, it is clear that after the medical staff inserts the puncture needle 603 of the subcutaneous infusion syringe 60 into the patient's subcutaneous tissue to a certain depth through the subcutaneous infusion positioning hole 101 at the desired location, they can rotate the handle 6022 to push the sealing piston 6021 along the length of the syringe 601, so as to slowly infuse the required medication into the patient's subcutaneous tissue. Because the subcutaneous fat layer of the patient is generally thick, there will be great resistance during this infusion process, and the sealing piston 6021 can only be moved slowly along the length of the syringe 601. When using a traditional syringe to inject medication subcutaneously by pressing the plunger, the piston at the tip of the plunger is prone to rebound due to high resistance, making it difficult for the medication to enter the subcutaneous tissue. Furthermore, the pressing operation is very laborious. To address this, this application designs a new subcutaneous infusion syringe 60 that uses the rotating handle 6022 to drive the sealed piston 6021 along the length of the syringe barrel 601, thus slowly infusing the required medication subcutaneously. This process eliminates the need for medical personnel to press the plunger, making medication infusion much less strenuous.

[0116] Furthermore, because the rear end of the sealing piston 6021 is threadedly connected to the inner wall of the syringe 601, the sealing piston 6021 is not prone to rebounding outwards, making it less likely for the infused medication to flow back under the patient's skin. At the same time, because the outer wall of the front end of the sealing piston 6021 is provided with a soft rubber sealing ring A60211 that tightly abuts against the inner wall of the syringe 601, even if the rear end of the sealing piston 6021 is threadedly connected to the inner wall of the syringe 601, the medication pre-filled in the syringe 601 is not likely to overflow through the rear end of the sealing piston 6021, thus making the subcutaneous infusion syringe 60 of this application highly reliable in use.

[0117] Furthermore, in this application, the rear end of the puncture needle 603 is provided with a connecting seat 6031. The connecting seat 603 is preferably threaded onto the outside of the Luer connector 6011, and the outer wall of the Luer connector 6011 is fitted with a soft rubber sealing ring B60111 near its connecting end, which can tightly abut against the inner wall of the connecting seat at the rear end of the puncture needle. In this way, the drug solution is less likely to overflow from the rear end of the puncture needle 603 during the process of infusing the drug solution into the patient's subcutaneous tissue.

[0118] Furthermore, in specific implementation, the end of the throttle 6022 is provided with an anti-detachment ball head 60221, so that when the operator holds the throttle 6022 and rotates it, he can simultaneously hold the anti-detachment ball head 60221 and make it less likely to slip out of his hand, thus making the application more stable to use.

[0119] Furthermore, through the above-mentioned optimized design, the subcutaneous infusion syringe 60 described in this application achieves excellent results.

[0120] Furthermore, in specific implementation, according to the multi-site subcutaneous infusion auxiliary device 1000 provided in the embodiment of the present invention, the thickness of the multi-site subcutaneous infusion positioning patch 10 is preferably set to about 0.5 cm, so as to be neither too thick nor too thin.

[0121] Other embodiments, etc., will not be described here.

[0122] In summary, the multi-site subcutaneous infusion auxiliary device 1000 provided in this application, in specific implementation, involves first disinfecting the patient's abdomen or the tensor fasciae latae region of the anterolateral thigh with iodine solution, then adhering the multi-site subcutaneous infusion positioning patch 10 described in this application to the skin surface of the patient's abdomen or the tensor fasciae latae region of the anterolateral thigh. Then, puncture needles can be inserted into the multiple subcutaneous infusion positioning holes 101, regardless of their position, to infuse the required medication into the patient's subcutaneous tissue via the connected subcutaneous infusion syringe 60. For related operations, the position and distance of the subcutaneous infusion positioning holes 101 are pre-defined, preventing the multiple puncture points from being too concentrated, thus reducing the risk of local bleeding, infection and inflammation, pain and hematoma, nerve and vascular damage at the subcutaneous puncture site due to concentrated puncture points, making this application safe and reliable to use.

[0123] Furthermore, since the position and distance of the subcutaneous infusion positioning port 101 are predetermined, compared with the related operations in the prior art, medical staff do not need to estimate and determine by visual means, which can greatly reduce the physical exertion of medical staff. Moreover, it is less likely that the same puncture point will be repeatedly located, resulting in repeated punctures. This is because after a subcutaneous infusion positioning port 101 is used, it can be marked on its side for differentiation, which makes the operation of this application highly reliable.

[0124] Furthermore, because the multi-site subcutaneous infusion positioning patch 10 has a certain layer thickness and is made of butene copolymer, gelatin, polypropylene glycol and ethylene-vinyl acetate copolymer, it is malleable and deformable. As a result, it is soft and clay-like, and can be molded into any desired shape. It also has self-adhesive properties. When it is adhered to the skin surface of the patient's abdomen or the anterolateral tensor fasciae latae region, even if the skin of the relevant adhesion area is uneven, it will automatically shape itself when the multi-site subcutaneous infusion positioning patch 10 is pressed with a little force, so as to automatically fill the uneven parts of the skin surface of the patient's abdomen or the anterolateral tensor fasciae latae region. This achieves a more stable adhesion to the skin surface of the patient's abdomen or the anterolateral tensor fasciae latae region, making the use of this application more reliable.

[0125] Furthermore, in actual use of this application, the puncture needle is inserted directly through the sterile hemostatic cotton ball 20 into the subcutaneous tissue of the relevant patient to administer subcutaneous fluid replacement. Then, the moment the puncture needle is withdrawn, the sterile hemostatic cotton ball 20 can be used to isolate the relevant puncture site and absorb any oozing blood, so as to avoid blood from the relevant puncture site splashing everywhere and causing cross-infection.

[0126] Meanwhile, when the sterile hemostatic cotton ball 20 at a certain location absorbs blood and turns red, it indicates that the relevant subcutaneous infusion positioning hole 101 has been used, so that the sterile hemostatic cotton ball 20 can also serve as a marking function, saving medical staff from marking it separately, and making it less likely that the same puncture point will be repeatedly positioned, resulting in repeated punctures.

[0127] Furthermore, in practical use of this application, by setting the positioning seat 50 and opening multiple positioning slots 501, after the puncture needle of the subcutaneous infusion syringe 60 is inserted into the subcutaneous tissue of the relevant patient through the subcutaneous infusion positioning hole 101 at the required position, the lower half of the syringe barrel of the subcutaneous infusion syringe 60 is fitted and stabilized by the positioning slots 501 at the corresponding positions. This allows medical personnel to operate it with one hand to inject the internal medication into the subcutaneous tissue of the relevant patient for fluid replacement. Moreover, especially when multiple subcutaneous infusion syringes 60 are used in sequence, the lower halves of the corresponding syringe barrels can all be fitted and stabilized, allowing medical personnel to free up their hands to operate each of the multiple subcutaneous infusion syringes 60 with one hand. Thus, the use of this application greatly facilitates medical personnel.

[0128] Furthermore, after the medical staff inserts the puncture needle 603 of the subcutaneous infusion syringe 60 into the subcutaneous infusion positioning hole 101 at the desired location to a certain depth, they can rotate the handle 6022 to push the sealing piston 6021 along the length of the syringe 601, so as to slowly infuse the required medication into the patient's subcutaneous tissue. This process eliminates the need for the medical staff to perform pressing operations, making the medication infusion less strenuous. Because the rear end of the sealing piston 6021 is threaded to the inner wall of the syringe 601, this... This also makes it difficult for the sealing piston 6021 to bounce back outward, preventing the medication from flowing back after being infused under the patient's skin. Because the outer wall of the front end of the sealing piston 6021 is provided with a soft rubber sealing ring A60211 that tightly abuts against the inner wall of the syringe 601, even if the rear end of the sealing piston 6021 is threadedly connected to the inner wall of the syringe 601, the medication pre-filled in the syringe 601 is not likely to overflow through the rear end of the sealing piston 6021, thus making the subcutaneous infusion syringe 60 of this application highly reliable.

[0129] Furthermore, the multi-site subcutaneous infusion auxiliary device 1000 provided in this application is indeed highly practical and has excellent effects, which makes this application inherently valuable for market promotion and will certainly be very popular and effectively popularized.
