Description

TECHNICAL FIELD

[0001] The utility model relates to medical auxiliary appliance technical field, concretely relates to a tool for flushing and sealing multiple lumens of catheter simultaneously. BACKGROUND

[0002] Double-lumen catheter and multi-lumen catheter are commonly used in hemodialysis patients, critically ill patients in intensive care unit, and patients who need repeated intravenous infusion of blood products and cannot stop using conventional drugs. The multi-lumen structure can ensure the opening of multiple channels in the vein, allowing drugs to be injected into the vein. The part of the double-lumen and multi-lumen catheter outside the human body is independent of each tube, and merges into one lumen after entering the human body.

[0003] Currently, according to the "Technical Operation Specification for Intravenous Therapy Nursing" and "Infusion Therapy Standards" published by the American Intravenous Nurses Association, if a patient has multiple lumens, even if only one lumen is used, it is necessary to flush and seal each lumen after use to prevent the catheter from being blocked. For double-lumen or multi-lumen catheters, it is appropriate to flush and seal multiple lumens simultaneously with one hand to prevent blood from flowing back into other lumens due to flushing only one lumen. Correspondingly, after infusion is completed, pulse flushing and positive pressure sealing can effectively prevent catheter blockage. Pulse flushing, which uses the "push-stop-push" method, can form small eddies in the catheter compared to continuous flushing, which helps to flush away residual drug solution attached to the catheter and blood vessel wall. When sealing, using the method of pushing and withdrawing the needle at the same time when there is 0.5-1 mL of sealing liquid left, i.e. positive pressure sealing, can maintain positive pressure in the catheter and prevent blood from flowing back, thereby preventing poor blood flow or catheter blockage.

[0004] Currently, in order to perform standardized catheter flushing and sealing according to the guidelines, clinical nursing staff need to be trained in operation standards, and the entire flushing and sealing process is completed by clinical nurses using the thenar eminence of the palm. The entire process includes syringe selection, manual pulse injection of the syringe, manual positive pressure sealing, and multiple lumens of the multi-lumen catheter, which are all flushed and sealed by the nurse with one hand. Therefore, the operation requires high skill of the clinical nursing staff. In addition, when the nurse flushes and seals multiple lumens with one hand, the pressure in each syringe and lumen is not uniform due to the force point being in the thenar eminence, which can easily cause the drug solution to flow back into the lumen with relatively low pressure, affecting the flushing and sealing effect and posing a safety hazard. At the same time, due to the heavy workload of clinical nursing, manual methods increase the workload of nurses and can cause hand muscle damage over a long period of time. SUMMARY

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical scheme and advantage of the embodiments of the present application more clear, the technical scheme in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, not all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0023] The inventor has found that, at present, in order to perform standardized catheter flushing and sealing according to the requirements of guidelines, clinical nursing personnel need to be trained to operate standardly, and the entire catheter flushing and sealing is completed by clinical nurses using the thenar eminence of the palm by hand. The entire process includes syringe selection, manual pulse injection of the syringe, manual realization of positive pressure sealing, and catheter flushing and sealing of multiple lumens by a nurse with one hand. Therefore, the operation ability of the clinical nursing personnel is required to be high when injecting. In addition, when the nurse performs multiple lumen flushing and sealing with one hand, the pressure in each syringe and each lumen is not uniform because the force point is in the thenar eminence, which easily leads to backflow of the liquid medicine into the lumen with relatively low pressure, thereby affecting the effect of catheter flushing and sealing and causing safety hazards. At the same time, due to the large amount of clinical nursing work, the manual method increases the workload of the nurses, and long time can easily cause hand muscle injury and other problems.

[0024] Based on the above findings, the application proposes a tool for simultaneous flushing and sealing of multi-lumen catheter, which designs a front plate 1 and a rear plate 2 connected by an extension rod 3. The front plate 1 is provided with a containing hole 101 and a clamp 4 for clamping the syringe tube. The rear plate 2 is embedded with a containing seat 201 for placing the tail end of the piston handle of the syringe, preliminarily fixing the position of the syringe. The left and right sides of the front plate 1 and the rear plate 2 are respectively provided with penetrating holes 5. The penetrating hole 5 of the front plate 1 is used for placing the index finger of the operator, and the penetrating hole 5 of the rear plate 2 is used for placing the thumb of the operator. When the operator pushes the rear plate 2 forward with the thumb, the flushing of the multi-lumen catheter can be realized. Embodiment one
