Description

Technical Field

[0001] This invention relates to the field of medical equipment technology, and in particular to a flushing and sealing device for infusion catheters. Background Technology

[0002] Clinically, infusion catheters require different flushing and sealing methods. For example, indwelling needles require 5ml flushing and sealing, while medium-length, PICC, CVC, and port-a-cath require syringes of 10ml or more, and different fluid volumes. Furthermore, different flushing and sealing techniques require nurses to memorize the syringes and techniques used, increasing their workload. A problem with this approach is that nurses find it difficult to quickly learn different injection techniques, and in practice, they need to repeatedly verify the injection technique and the correct specifications of the flushing and sealing equipment, especially for inexperienced novice medical staff. Therefore, we propose an infusion catheter flushing and sealing device. Summary of the Invention

[0003] The main objective of this invention is to provide a device for flushing and sealing infusion catheters.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] An infusion catheter flushing and sealing device includes a processing and mounting carrier. A control board integration assembly and an injection control component are disposed on the outer side of the processing and mounting carrier. An injection syringe locking component and a locking model response component are disposed on the inner side of the processing and mounting carrier. The control board integration assembly is signal-connected to the injection syringe locking component and the locking model response component. The control board integration assembly is used to set the processing signal of the injection control component according to the flushing and sealing method. The injection control component is used to fix the syringe plunger and control the plunger to complete the injection flushing and sealing according to the sealing method. After the control board integration assembly selects the flushing and sealing method for the injection control component, the injection syringe locking component verifies whether the currently assembled syringe meets the sealing requirements.

[0006] The injection syringe locking assembly is used to calibrate the clamping distance according to the syringe size inside the treatment mounting carrier. The injection syringe locking assembly includes several positioning clips, an inner arc locking pad, and a telescopic propulsion mechanism. The positioning clips are slidably connected to the inside of the treatment mounting carrier, the inner arc locking pad is fixedly connected to the outer wall of the positioning clips, and the telescopic propulsion mechanism is disposed inside the treatment mounting carrier. The output end of the telescopic propulsion mechanism is fixedly connected to the positioning clips.

[0007] The locking response component includes a flexible tensioning connection, a separating positioning strip, a pressure sensing response unit, and a displacement sensing unit. The flexible tensioning connection is fixedly connected between two adjacent positioning clips. A pressure sensing response unit is fixedly connected between the separating positioning strip and the inner arc locking pad. The pressure sensing response unit is used to obtain the contact pressure after the syringe is clamped to verify the clamping stability. The displacement sensing unit is used to obtain the extension length of the telescopic propulsion mechanism when the syringe is fixed to determine whether the current syringe size is consistent with the processing method of the punching and sealing tube selected by the control board integration group.

[0008] A further improvement of the present invention is that the injection control component includes an electromagnetic locking buckle, an upper push cap, an injection action guide module, and an electric flipping mechanism. The electromagnetic locking buckle is fixedly connected to the inner side of the upper push cap and is used to fix the syringe plunger. The electric flipping mechanism is fixedly connected to the sliding transmission end of the injection action guide module, and the upper push cap is fixedly connected to the rotation transmission end of the electric flipping mechanism. The injection action of the flushing and sealing tube is achieved by driving the upper push cap to slide longitudinally through the injection action guide module.

[0009] A further improvement of this invention is that the control board integrated group includes a dynamic switching module for flushing and sealing tubes, a sub-item touch control module, a flushing and sealing tube form command input module, a dynamic display module, and a main control microprocessor. The flushing and sealing tube form command input module pre-inputs operation commands for controlling the driving amount of the propulsion action guidance module based on the flushing and sealing tube injection volume requirements. The main control microprocessor stores the operation commands pre-input by the flushing and sealing tube form command input module. After the dynamic switching module for flushing and sealing tubes sends an execution instruction to the main control microprocessor based on the flushing and sealing tube operation requirements, the corresponding operation command stored in the main control microprocessor is selected through the sub-item touch control module. The dynamic display module is used to display the corresponding flushing and sealing tube operation command currently being executed by the main control microprocessor.

[0010] A further improvement of the present invention is that a lower positioning shell of the cylinder is fixedly connected to the bottom of the processing installation carrier, and a syringe sleeve is fixedly connected to the top of the processing installation carrier. The lower positioning shell of the cylinder and the syringe sleeve are used to support the operating syringe when the tube is flushed.

[0011] A further improvement of the present invention is that the use of an infusion catheter flushing and sealing device includes the following steps:

[0012] Step S1: Input the punching and sealing tube selection command to the punching and sealing tube dynamic switching module through the sub-item touch control module set by the control board integrated group. After the main control microprocessor receives the trigger signal of the punching and sealing tube dynamic switching module, it reads the corresponding punching or sealing tube requirements entered by the punching and sealing tube form command input module. At this time, the operator is prompted to select the injection syringe corresponding to the currently selected command through the dynamic screen display module.

[0013] Step S2: After selecting the injection syringe, insert the injection syringe into the positioning clip inside the mounting carrier. Then, the main control microprocessor sends a control signal to the telescopic propulsion mechanism. The telescopic propulsion mechanism drives the inner arc locking pad to clamp the syringe. After clamping, the displacement sensing unit obtains the range of motion of the telescopic propulsion mechanism, and the pressure sensing response unit obtains the pressure applied to the syringe clamping. It verifies whether the specifications of the currently inserted syringe meet the corresponding requirements of the flushing or sealing tube input module.

[0014] Step S3: If the verification is not compliant, the dynamic display module will prompt the operator to replace the syringe with one of the corresponding specifications. If the verification is compliant, the main control microprocessor will send a control command to the electric flipping mechanism, which will drive the upper push cover to close the upper end of the syringe casing and clamp the syringe push head part with the electromagnetic locking buckle. Then, the main control microprocessor will send a push control signal to the push action guide module according to the selected flushing or sealing requirements, and control the push action guide module to complete the push action of the needle push head at a fixed distance.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: The flushing and sealing tube type command input module pre-inputs the operation command for controlling the driving amount of the propulsion action guide module based on the flushing and sealing tube injection volume requirements. After the flushing and sealing tube selection command is input to the flushing and sealing tube dynamic switching module through the sub-item touch module set by the control board integrated group, the dynamic screen display module prompts the operator to select the injection syringe corresponding to the currently selected command. The displacement sensing unit obtains the movement range of the telescopic propulsion mechanism, and the pressure sensing response unit obtains the pressure applied by the syringe clamp. It verifies whether the currently inserted syringe specification meets the corresponding flushing or sealing tube requirements input by the flushing and sealing tube type command input module, which can effectively reduce the probability of misoperation by medical personnel. When the verification is satisfactory, the main control microprocessor sends a control command to the electric flipping mechanism and, based on the selected flushing or sealing tube requirements, sends a push control signal to the propulsion action guide module, controlling the propulsion action guide module to complete the needle push action at a fixed distance, thus improving the flushing and sealing tube efficiency.

[0021] The present invention will be further described below with reference to specific embodiments. The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual pictures. They should not be construed as limiting the present invention. In order to better illustrate the specific embodiments of the present invention, some parts in the drawings may be omitted, enlarged or reduced, and do not represent the actual product size. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1-4 The system includes a processing and installation carrier 1. A control board integration group 3 and an injection control component 4 are provided on the outside of the processing and installation carrier 1. An injection syringe locking component 5 and a locking model response component 6 are provided on the inside of the processing and installation carrier 1. The control board integration group 3 is connected to the injection syringe locking component 5 and the locking model response component 6. The control board integration group 3 is used to set the processing signal of the injection control component 4 according to the tube flushing and sealing method. The injection control component 4 is used to fix the syringe push head and control the push head to complete the injection flushing and sealing according to the tube sealing method. After the control board integration group 3 selects the injection control component 4 to perform the tube flushing and sealing process, the injection syringe locking component 5 verifies whether the currently assembled syringe meets the tube sealing requirements.

[0023] In this embodiment, the present invention aims to solve the problem that in clinical practice, different flushing and sealing methods are required for infusion catheters due to different techniques for Western medicine. Nursing staff find it difficult to record different injection techniques in a short period of time, and need to check the current injection technique and the specifications of the flushing and sealing device multiple times during actual operation.

[0024] The syringe locking assembly 5 is used to calibrate the clamping distance according to the syringe size inside the treatment mounting carrier 1. The syringe locking assembly 5 includes several positioning clips 51, an inner arc locking pad 52, and a telescopic pushing mechanism 53. The positioning clips 51 are slidably connected to the inside of the treatment mounting carrier 1, the inner arc locking pad 52 is fixedly connected to the outer wall of the positioning clips 51, and the telescopic pushing mechanism 53 is located inside the treatment mounting carrier 1. The output end of the telescopic pushing mechanism 53 is fixedly connected to the positioning clips 51.

[0025] In this embodiment, the telescopic propulsion mechanism 53 is an electromagnetic telescopic rod. The telescopic propulsion mechanism 53 and the positioning clasp 51 are arranged in a ring. The telescopic propulsion mechanism 53 pushes the positioning clasp 51 and clamps and fixes the syringe. The inner arc locking pad 52 is filled inside the positioning clasp 51. When the telescopic propulsion mechanism 53 pushes the positioning clasp 51 to clamp the syringe, the inner arc locking pad 52 provides stress buffering during clamping.

[0026] The locking model response component 6 includes a flexible tensioning connection part 61, a separating positioning strip 62, a pressure sensing response unit 63, and a displacement sensing unit 64. The flexible tensioning connection part 61 is fixedly connected between two adjacent positioning clips 51. The pressure sensing response unit 63 is fixedly connected between the separating positioning strip 62 and the inner arc locking pad 52. The pressure sensing response unit 63 is used to obtain the contact pressure after the current syringe is clamped, and is used to verify the clamping stability. The displacement sensing unit 64 is used to obtain the extension length of the telescopic propulsion mechanism 53 when the syringe is fixed, and is used to determine whether the current syringe size is consistent with the processing method of the punching and sealing tube selected by the control board integration group 3.

[0027] In this embodiment, when the telescopic propulsion mechanism 53 pushes the positioning clasp 51 to fix the syringe, the displacement sensing unit 64 reads the activity path parameters of the extended end of the telescopic propulsion mechanism 53. After the main control microprocessor 35 obtains the collected parameters from the displacement sensing unit 64, the pressure sensing response unit 63 determines whether the clamping pressure of the current positioning clasp 51 after merging meets the required size parameters for the tube sealing injection volume. At the same time, based on the comparison between the current activity path parameters of the telescopic propulsion mechanism 53 and the pre-entered required size parameters for the tube sealing injection volume, it verifies whether the specifications of the currently inserted syringe meet the corresponding requirements for tube flushing or tube sealing entered by the tube flushing and sealing form command entry module 33.

[0028] The injection control component 4 includes an electromagnetic locking buckle 41, an upper push cap 42, a push action guide module 43, and an electric flipping mechanism 44. The electromagnetic locking buckle 41 is fixedly connected to the inner side of the upper push cap 42 and is used to fix the syringe pusher. The electric flipping mechanism 44 is fixedly connected to the sliding transmission end of the push action guide module 43, and the upper push cap 42 is fixedly connected to the rotation transmission end of the electric flipping mechanism 44. The push action of the flushing and sealing tube is realized by driving the upper push cap 42 to slide longitudinally through the push action guide module 43.

[0029] In this embodiment, after the electric flipping mechanism 44 controls the upper push cover 42 to flip to the top position of the injection syringe shell 2, the electromagnetic fixing latch 41 is used to lock and fix the syringe push head. After the electromagnetic fixing latch 41 locks and pushes the syringe, the push action guide module 43 drives the electromagnetic fixing latch 41 to complete the longitudinal extension along the inner path of the injection syringe shell 2 according to the control signal sent by the main control microprocessor 35, thereby completing the injection of the syringe to fix the inner side of the positioning cover 51.

[0030] The control board integrated group 3 includes a dynamic switching module for punching and sealing tubes 31, a sub-item touch module 32, a punching and sealing tube form command input module 33, a dynamic display module 34, and a main control microprocessor 35. The punching and sealing tube form command input module 33 pre-inputs operation commands for controlling the driving amount of the push-in action guide module 43 based on the punching and sealing tube injection volume requirements. The main control microprocessor 35 stores the operation commands pre-input by the punching and sealing tube form command input module 33. After the dynamic switching module for punching and sealing tubes 31 sends the execution instruction to the main control microprocessor 35 according to the punching and sealing tube operation requirements, the corresponding operation command stored in the main control microprocessor 35 is selected through the sub-item touch module 32. The dynamic display module 34 is used to display the corresponding punching and sealing tube operation command currently executed by the main control microprocessor 35.

[0031] The bottom of the processing and installation carrier 1 is fixedly connected to the lower positioning shell 11 of the cylinder, and the top of the processing and installation carrier 1 is fixedly connected to the syringe sleeve 2. The lower positioning shell 11 and the syringe sleeve 2 are used to support the operating syringe when the tube is flushed.

[0032] In this embodiment, the syringe sleeve 2 and the lower positioning shell 11 are both used for external protection when the syringe is inserted into the positioning clip 51 inside the treatment mounting carrier 1, so as to prevent the syringe from being displaced by external forces during the injection process.

[0033] The method of using this invention includes the following steps:

[0034] Step S1: Input the punching and sealing tube selection command to the punching and sealing tube dynamic switching module 31 through the sub-item touch control module 32 set by the control board integrated group 3. After receiving the trigger signal from the punching and sealing tube dynamic switching module 31, the main control microprocessor 35 reads the punching or sealing tube corresponding requirements entered by the punching and sealing tube form command input module 33. At this time, the operator is prompted to select the injection syringe corresponding to the currently selected command through the dynamic screen display module 34.

[0035] Step S2: After selecting the injection syringe, insert the injection syringe into the positioning clip 51 inside the processing and installation carrier 1. Then, the main control microprocessor 35 sends a control signal to the telescopic propulsion mechanism 53. The telescopic propulsion mechanism 53 drives the inner arc locking pad 52 to clamp the syringe. After clamping, the displacement sensing unit 64 obtains the range of motion of the telescopic propulsion mechanism 53, and the pressure sensing response unit 63 obtains the pressure applied to the syringe clamping. It verifies whether the specifications of the currently inserted syringe meet the corresponding requirements of the flushing or sealing tube input module 33.

[0036] Step S3: If the verification is not compliant, the dynamic display module 34 will display a prompt to the operator to replace the syringe with the corresponding specification. If the verification is compliant, the main control microprocessor 35 will send a control command to the electric flipping mechanism 44. The electric flipping mechanism 44 will drive the upper push cover 42 to close the upper end of the syringe shell 2 and clamp and fix the syringe push head part through the electromagnetic locking buckle 41. Then, according to the selected flushing or sealing requirements, the main control microprocessor 35 will send a push control signal to the push action guide module 43 to control the push action guide module 43 to complete the push action of the needle push head at a fixed distance.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of this invention is defined by the appended claims and their equivalents.
