Description

Technical Field

[0001] The invention relates to the technical field of disposable infusion sets, in particular to a disposable infusion set for assisting subcutaneous injection. Background Art

[0002] The patient-controlled disposable infusion device is a pain management technology that is pre-set by medical staff according to the patient's pain level and physical condition, and then handed over to the patient for "self-management". According to the patient's condition, the PCA drug delivery mode includes: simple PCA, the patient is completely self-controlled, the patient presses the PCA control device when in pain, and a single dose is given; background infusion plus a single dose, on the basis of continuous infusion of a certain drug, the patient increases a single dose when in pain; loading amount plus background infusion plus a single dose, when the patient is in pain, first give a loading amount to let the patient quickly eliminate the pain, and then continuously infuse a certain drug, and the patient increases a single dose when in pain.

[0003] A Chinese invention patent with publication number CN205683355U discloses a disposable infusion set for injection analgesia, which can facilitate upper arm muscle injection and has high skin-friendliness and overpressure protection function, including a pressing piece and a drawstring, wherein one end surface of the pressing piece is provided with a protruding needle, and the other end surface is provided with a furry surface that matches with Velcro, and the furry surfaces are at least two and are respectively arranged on both sides of the puncture hole; both ends of the drawstring are provided with hook surfaces that match with the furry surfaces tightly; the pressing piece and the protruding needle should be made of soft skin-friendly materials. The utility model has a simple structure, is easy to use, has a wide range of applications, has a good disposable infusion set effect, has low side effects, and has a good market promotion prospect.

[0004] In addition, since patients inject pain-relieving drugs into their bodies through disposable infusion sets according to their own pain conditions, generally, a person inserts an injection needle into the human body by holding a disposable infusion set, and then presses down with the thumb to inject the drug inside the disposable infusion set into the human body. Since different individuals have different minimum effective analgesic doses and minimum effective blood drug concentrations under different conditions, patients need to hold the disposable infusion set for long-term slow injection. Therefore, in the disposable infusion set disclosed by Chinese invention patent CN205683355U, during the injection process, the patient cannot keep the injection needle in the human body for a long time, which will increase the pain at the needle eye of the patient. In addition, when injecting some drugs with higher concentrations, the patient cannot increase the absorption efficiency of the drug by the subcutaneous tissue in a short period of time, which will cause a feeling of distension and pain at the needle eye.

[0038] A disposable infusion set for assisting subcutaneous injection, reference Figure 1 As shown, it includes a support plate 1 and a limiting slide groove 2, and the limiting slide groove 2 is symmetrically opened on the support plate 1;

[0039] In view of the above-mentioned disposable infusion set for assisting subcutaneous injection, it can be specifically implemented as follows:

[0043] Summary 1: Compared with the prior art, a person inserts the injection needle into the human body by holding the disposable infusion set, and then presses down with the thumb to inject the medicine inside the disposable infusion set into the human body, so the stability of the disposable infusion set 6 during injection cannot be guaranteed. Therefore, the elastic force generated by the deformation of the special-shaped rubber plate 37 and the spring 1 313 is used to buffer the external force on the disposable infusion set 6, thereby preventing the disposable infusion set 6 from deviating too much and causing the needle to pierce the subcutaneous tissue around the needle eye hole, thereby improving the stability of the disposable infusion set 6 during injection.

[0044] refer to Figures 6 to 8As shown, the knocking mechanism 4 is used to knock the skin around the needle hole, which prevents the person from injecting too quickly through the disposable infusion set 6 and relieves the distending pain at the needle hole;

[0045] refer to Figures 6 to 8 As shown, the knocking mechanism 4 includes a rectangular groove plate 1 41 fixedly connected to the upper surface of the support plate 1, and four driving buttons 42 are fixedly connected to the inner wall of the rectangular groove plate 1 41 in a circular array. A rectangular groove plate 2 43 is vertically slidably connected inside the rectangular groove plate 1 41. The size of the rectangular groove plate 2 43 is adapted to the size of the disposable infusion set 6, and the size of the rectangular groove plate 2 43 is adapted to the size of the top of the inner cavity of the rectangular groove plate 1 41. The lower surface of the rectangular groove plate 2 43 is arranged in a circular array and has four electric shock grooves 44. The electric shock grooves 44 and the driving buttons 42 are on the same vertical plane, and the size of the electric shock grooves 44 is adapted to the size of the driving buttons 42. There is electrical contact between the electric shock grooves 44 and the power supply. The lower surface of the rectangular groove plate 1 41 is arranged in a circular array and fixedly connected with four telescopic rods 2 45. The driving device inside the telescopic rod 2 45 is electrically connected to the driving button 42. The telescopic end of the telescopic rod 2 45 away from the rectangular groove plate 1 41 is fixedly connected with a knocking plate 46. The size of the knocking plate 46 is smaller than the size of the groove opened on the top of the special-shaped rubber plate 37. The disposable infusion set 6 slides vertically inside the rectangular groove plate 2 43. The knocking plate 46 gently taps the skin around the needle eye, which can promote the rate of drug absorption by the surrounding skin tissue. In the process of tapping the skin, the patient's skin touch is diverted, which effectively avoids the patient's perception of pain.

[0046] It should be noted that the working principle of the drive button 42 is similar to that of the control button. The working principle of the electronic control button is based on the principle of electronic circuits. It is usually an electronic switch element, such as a micro switch or a touch switch. When the button is pressed, the button changes the state of its internal circuit and generates an electrical signal. This electrical signal can be a change from a low level to a high level (or vice versa), which is transmitted to the control circuit board of the device through a wire. After receiving this signal, the microprocessor or logic circuit on the control circuit board makes judgments and processes according to a pre-written program.

[0047] Summary 2: Compared with the prior art, when a person performs an injection, due to the difference between the minimum effective analgesic dose and the minimum effective blood drug concentration and the inability of the person to control the speed after the injection, a feeling of distension and pain will occur at the needle hole. Therefore, the telescopic end of the telescopic rod 2 45 drives the knocking plate 46 to repeatedly tap the skin tissue around the needle hole, which can accelerate the absorption of the drug by the subcutaneous tissue, avoid the impact of the drug concentration on the absorption effect of the subcutaneous tissue when it is too high, and prevent excessive high-concentration drugs from accumulating in the subcutaneous tissue to cause distension and pain in the needle hole. At the same time, by knocking the skin around the needle hole with the knocking plate 46, the patient's attention can be effectively diverted, reducing the patient's perception of pain.

[0048] refer to Figures 4 to 9 As shown, the fixing mechanism 5 is used to fix the disposable infusion set 6, so that the disposable infusion set 6 and the knocking mechanism 4 are always fixed;

[0049] refer to Figures 4 to 9 As shown, the fixing mechanism 5 includes a fixing plate 2 51 symmetrically fixedly connected to the outer wall of the rectangular groove plate 2 43, and a limited position abutment block 52 is symmetrically fixedly connected to the outer wall of the fixing plate 2 51. The lower surface of each fixing plate 2 51 is fixedly connected to a fixing plate 3 53, and a hinge rod 1 54 is fixedly connected to the outer wall of the fixing plate 3 53. A sleeve 55 is rotatably connected to the outer wall of the hinge rod 1 54. The sleeve 55 is adapted to the size of the hinge rod 1 54. A spring 2 56 is fixedly connected between the two sleeves 55. The two fixing plates 2 51 are connected to each other. A rotating rod 57 is connected to the rotating rod 57 for rotation. The rotating rod 57 and the hinge rod 1 54 are on the same vertical horizontal plane. The rotating rod 57 and the limit contact block 52 are on the same water surface. A clamping block 2 58 is fixedly connected to the middle outer wall of the rotating rod 57. A hinge rod 2 59 is fixedly connected to the outer wall of the rotating rod 57 away from the clamping block 2 58. The length of the hinge rod 2 59 is greater than the distance between the rotating rod 57 and the limit contact block 52. The clamping block 2 58 is made of rubber. The hinge rod 2 59 and the clamping block 2 58 are both set to L shape.

[0050] Summary 3: Compared with the prior art, when personnel install the disposable infusion set 6, not only are the steps cumbersome but also the timeliness of the injection is affected. Therefore, the disposable infusion set 6 is fixed by the clamping block 2 58, so that disposable infusion sets 6 of various specifications can be fixed, and the disposable infusion set 6 can be quickly disassembled, thereby improving the flexibility of the device.

[0051] The following is the working process and principle of the above embodiment:

[0052] The initial state is as follows: the special-shaped rubber plate 37 does not deform to expand to both sides, the telescopic rod 1 312 is in an unstretched state, the spring 1 313 is in an unstretched state, the telescopic rod 2 45 is in an unstretched state, and the spring 2 56 is in an unstretched state.

[0053] The working steps are as follows:

[0054] The patient wraps the support plate 1 around the part requiring injection through the hinge plate 131 and the rubber bandage 32, and the personnel connects the clamp ring 34 with the buckle 35 to bind the rubber bandage 32 to the human skin, so that the support plate 1 drives the special-shaped rubber plate 37 to press against the human body through the fixed block 136, so that the special-shaped rubber plate 37 is expanded to both sides under the resistance of the human body, and then the special-shaped rubber plate 37 drives the hinge block 138 to expand to both sides synchronously, so that the hinge block 138 drives the bottom end of the fixed rod 139 rotatably connected thereto to move synchronously, so that the top end of the fixed rod 139 moves inside the limiting slide groove 12 to the side away from the hinge block 138, and then the fixed rod 139 drives the fixed rod 2 310 to move synchronously to the side away from the hinge block 138, so that the fixed rod 2 310 drives the cylindrical sleeve plate 311 sleeved therewith to move to the side away from the hinge block 138. , thereby making the cylindrical sleeve plate 311 drive the telescopic end of the telescopic rod 312 to move to the side away from the hinge block 38, thereby making the telescopic end of the telescopic rod 312 drive the spring 313 to stretch away from the fixed end of the telescopic rod 312, and at the same time making the fixed end of the telescopic rod 312 drive the set rotating rod to flip upward synchronously, under the action of the special-shaped rubber plate 37 and the rubber bandage 32, the support plate 1 and the patient are in a relatively static state, and at the same time, the rectangular groove plate 1 41 and the rectangular groove plate 2 43 are both in a relatively static state with the patient's body through the support plate 1, so that the elastic force generated by the deformation of the special-shaped rubber plate 37 and the spring 313 buffers the external force exerted on the disposable infusion set 6, thereby avoiding the excessive deviation of the disposable infusion set 6 causing the needle to pierce the subcutaneous tissue around the needle eye hole, thereby improving the stability of the disposable infusion set 6 during injection.

[0055] Then, personnel put the disposable infusion set 6 into the interior of the rectangular groove plate 2 43, so that the top end of the rectangular groove plate 2 43 contacts the outer wall of the disposable infusion set 6, and then the patient pushes the clamping block 2 58 toward the side close to the disposable infusion set 6, so that the clamping block 2 58 drives the rotating rod 57 to rotate inside the two fixed plates 2 51, so that the rotating rod 57 drives the hinged rod 2 59 to rotate synchronously, so that the top end of the hinged rod 2 59 rotates toward the side close to the rectangular groove plate 2 43, so that the hinged rod 2 59 drives the ring 55 rotatably connected thereto to rotate synchronously, and the ring 55 drives the spring 2 56 fixedly connected thereto to flip toward the side close to the rectangular groove plate 2 43 with the hinged rod 1 54 as the axis, and in the process of the rotation of the hinged rod 2 59, the ring 55 stretches the spring 2 56. The spring 2 56 generates an elastic force to contract inward. When the top of the hinged rod 2 59 rotates to the side of the rectangular groove plate 2 43 above the rotating rod 57, the elastic force of the spring 2 56 itself contracts drives the ring 55 to continue to rotate, so that the ring 55 drives the top of the hinged rod 2 59 to continue to rotate until the top of the clamping block 2 58 hits the outer wall of the disposable infusion set 6. At this time, the spring 2 56 no longer drives the hinged rod 2 59 to continue to rotate, so that the disposable infusion set 6 is fixed to the rectangular groove plate 2 43 under the resistance of the clamping block 2 58. The disposable infusion set 6 is fixed by the clamping block 2 58, thereby realizing the fixation of disposable infusion sets 6 of various specifications, and also realizing the effect of quick disassembly of the disposable infusion set 6, thereby improving the flexibility of the device.

[0056] After the disposable infusion set 6 is installed on the rectangular groove plate 2 43, the patient presses the rectangular groove plate 2 43 downward, so that the rectangular groove plate 2 43 moves toward one side of the human body inside the rectangular groove plate 1 41, so that the rectangular groove plate 2 43 drives the needle of the disposable infusion set 6 to move toward the human body through the clamping block 2 58, and the needle of the disposable infusion set 6 is inserted into the human body, and at the same time, the rectangular groove plate 2 43 drives the electric shock groove 44 to move toward the side close to the driving button 42, so that the driving button 42 enters the electric shock groove 44, and then The rear drive button 42 electrically controls the telescopic rod 45 to start reciprocating up and down motion, so that the telescopic end of the telescopic rod 45 drives the knocking plate 46 to repeatedly tap the skin tissue around the needle hole, which can accelerate the absorption of the drug by the subcutaneous tissue, avoid the impact of the drug concentration on the absorption effect of the subcutaneous tissue, and prevent excessive high-concentration drugs from accumulating in the subcutaneous tissue to cause swelling and pain in the needle hole. At the same time, by knocking the skin around the needle hole with the knocking plate 46, the patient's attention can be effectively diverted, reducing the patient's perception of pain.
