Description

Technical Field

[0001] The present invention relates to medical device manufacturing technology, in particular to an emergency drug discharge device for an intravenous infusion tube, and belongs to the technical field of medical product manufacturing. Background Art

[0002] During anesthesia induction, sedatives, analgesics, and muscle relaxants are administered. Overdose of anesthetic drugs can lead to hemodynamic fluctuations, especially in elderly patients with comorbid cardiovascular and cerebrovascular diseases. Hemodynamic fluctuations can cause perioperative cardiovascular and cerebrovascular damage in elderly patients, including myocardial hypoxia, arrhythmias, and cerebral infarction. Therefore, precise control of drug dosage is crucial during anesthesia.

[0003] Furthermore, because surgical duration is uncontrollable, the anesthesiologist can easily miscalculate the timing of drug administration, sometimes ending the surgery immediately after administration, which can delay the patient's recovery. Furthermore, patients with allergies may experience varying degrees of allergic reactions after receiving anesthetics. Severe cases may even lead to anaphylactic shock, requiring emergency treatment and the immediate withdrawal of the anesthetic.

[0004] Therefore, it is often necessary to urgently withdraw the drug after it is added to the intravenous infusion tube. This can effectively avoid overdose of anesthetic drugs, achieve precise drug administration during anesthesia, avoid overdose of anesthetic drugs, protect the vital signs of perioperative patients, and promote rapid awakening of patients.

[0005] In the prior art, in order to deal with such a situation, the infusion needle can be directly pulled out to stop the injection of drugs into the human body. However, once the infusion needle is pulled out, when performing subsequent operations, not only does it need to be injected again, but other drugs required for the anesthesia process also need to be re-configured, and the original drugs cannot be used again, which is extremely time-consuming.

[0006] Of course, existing technologies can also use a tee connection between the lower end of the infusion tube and the injection needle, and install a drainage tube there. However, this requires a dedicated medical staff to monitor the emergency discharge of the drug to prevent excessive leakage of other drugs and prevent blood from flowing back into the patient. In addition, the emergency discharge of drugs also requires a dedicated container. In actual use, this is extremely time-consuming and labor-intensive, and poses a significant safety hazard.

[0007] Therefore, there is an urgent need in the prior art for an emergency drug discharge device for an intravenous infusion tube that is easy to operate and controllable at any time. Summary of the Invention

[0033] The intravenous infusion tube drug emergency discharge device described in the present invention can be made of the following materials and components, but is not limited to the following materials and components, such as: intravenous infusion tube, spring sheet, grid plate, plastic tube, elastic tube, press button, hard support tube, etc.

[0034] like Figure 1 The figure shows the side structure of the emergency drug discharge device for intravenous infusion tube according to the embodiment of the present invention; Figures 2 to 5 .

[0035] The emergency drug discharge device for intravenous infusion tubes of the embodiment of the present invention is installed on the intravenous infusion set during use and is used vertically; or it can be directly integrated into the intravenous infusion set. In addition, the emergency discharge device of this embodiment can also be installed on a central venous catheter in clinical practice. Installing this device on a central venous catheter can achieve precise administration of vasoactive drugs. Compared with ordinary central venous catheters, the infusion set of this embodiment does not need to open the heparin cap of the central venous catheter during the drug discharge process, which can effectively avoid the formation of air embolism in the central venous catheter when the drug is discharged.

[0036] It should be noted that the upper end of the infusion tube in the present invention is connected to the intravenous infusion set and is located below the flow regulator and injection piece of the intravenous infusion set, while the lower end of the infusion tube is connected to the intravenous needle. The injection piece is the component that allows the addition of anesthetics or other drugs during the infusion process.

[0037] The embodiment of the present invention includes: an infusion tube 1, a storage tube 2, and a push switch; the push switch is used to open and close the device by pressing. The push switch can be implemented as a push switch valve or other device that can be opened and closed by mechanical pressing.

[0038] The storage tube 2 is sleeved on the outside of the infusion tube 1, and both ends of the storage tube 2 are sealed with the outer wall of the infusion tube 1; a storage space is formed between the inner wall of the storage tube 2 and the outer wall of the infusion tube 1 for storing medicines that need to be discharged urgently.

[0039] A guide hole 30 is provided on the side wall of the infusion tube 1 , and the infusion tube 1 is connected to the storage tube 2 through the guide hole 30 ; the push switch is installed on the guide hole 30 to open or close the guide hole 30 .

[0040] Generally, in order to ensure that the medicine is quickly discharged into the storage tube 2 through the guide hole 30, the storage tube 1 is provided with an exhaust pipe 5. The exhaust pipe 5 is used to automatically exhaust the air discharged after the medicine enters the storage tube 2, thereby ensuring that the medicine quickly flows into the storage tube 2.

[0041] Furthermore, an air filter 50 (also known as a precision filter) is provided at the top of the exhaust pipe 5. The air filter 50 is generally a cotton ball seal. The air filter 50 prevents external contaminated air from entering the storage tube 2. The exhaust pipe 5 is located at the top of the storage tube 2, thereby ensuring maximum drug storage space.

[0042] The present invention is used on an intravenous infusion tube. By pressing a switch with one hand, the diversion hole on the side wall of the infusion tube can be opened, so that in an emergency, the medicine in the infusion tube can be promptly diverted to the storage tube, thereby realizing the emergency withdrawal of the medicine and avoiding overdose.

[0043] like Figure 1 As shown, an emergency drug discharge device for an intravenous infusion tube according to one embodiment of the present invention comprises an infusion tube 1 having an elastic tube section 3; the push switch comprises: a support tube 7 and a hard button 6; the hard button 6 is mounted on the outside of the storage tube 2, and its height corresponds to the guide hole 30; the hard button 6 is used to control the opening and closing of the guide hole 30 by squeezing.

[0044] The support tube 7 is sleeved within the elastic tube section 3; the support tube 7 is a grid structure (it can also be a porous hollow structure) and has multiple filter holes; the elastic tube section 3 is provided with multiple diversion holes 30, each of which corresponds to the filter hole, thereby ensuring that the drug in the infusion tube 1 can be discharged through the filter hole and the diversion hole 30 in sequence; the elastic tube section 3 is a deformable flexible tube, generally a silicone tube, PP tube, or PC tube with a certain degree of elasticity; the diversion hole 30 is closed in a normal state. After being squeezed, it locally deforms, thereby opening the diversion hole 30, and then allowing the drug to flow out of the diversion hole.

[0045] The hard button 6 presses the support tube 7 to partially deform the elastic tube section 3 to open the guide hole 30 in that part.

[0046] The support tube 7 is generally made of elastic stainless steel or some plastic tubes with slightly higher hardness and good resilience, which plays the role of maintaining the shape of the elastic tube section 3. When the elastic tube section 3 maintains its initial shape, the diversion hole is in a closed state; only after being squeezed, the local deformation is too large, thereby causing the diversion hole to open.

[0047] Generally, there are two hard buttons 6, which are respectively arranged on both sides of the storage tube 2, so as to facilitate one-handed operation. By pressing the two hard buttons 6 at the same time, a more obvious deformation is generated.

[0048] Preferably, each of the hard buttons 6 is provided with a flexible pad 60 and is mounted on the outside of the storage tube 2 through the flexible pad 60; the flexible pad serves to connect the hard buttons.

[0049] Each of the hard buttons 6 is provided with a protrusion on the side facing the support tube 7. The protrusion can cause significant local deformation of the elastic tube section 3 and the support tube 7 without blocking the elastic tube section; and is used to enhance the effect of local deformation.

[0050] like Figures 2 to 5 Another embodiment of the intravenous infusion tube drug emergency discharge device of the present invention comprises an infusion tube 1 having a hard tube section 3; the guide hole 30 is provided on one side of the hard tube section 30; that is, located on one of the side surfaces.

[0051] The push switch 4 includes: a sliding sleeve, a spring sheet 42 and a support seat 40; the sliding sleeve is arranged on the outside of the hard pipe section 3 and is located in the storage tube 2; one side of the sliding sleeve is a circular arc contact shoe 43, and the other side of the sliding sleeve is a pressing sheet 41; the circular arc contact shoe 43 fits tightly with the guide hole 30 to close the guide hole 30; one end of the spring sheet 42 is fixed on the pressing sheet 41, and the other end rests on the hard pipe section 3; that is, one side of the sliding sleeve is used to seal the guide hole 30 from the side, and under normal conditions, the spring sheet 42 expands, so that the circular arc contact shoe 43 fits tightly on the guide hole 30 of the hard pipe section 3.

[0052] The support seat 40 is fixed on the hard pipe section 3 and corresponds to the guide hole 30; the support seat 40 is used to provide a fulcrum for pressing, thereby facilitating operation.

[0053] The support seat 40 and the pressing plate 41 are respectively located on both sides of the hard pipe section 3; the pressing plate 41 presses the spring plate 42 to slide toward the support seat 40, so that the arc contact shoe 43 and the guide hole 30 of the hard pipe section 3 are disengaged from each other to open the guide hole 30.

[0054] The sliding sleeve can slide radially from the hard tube section 3 and open the guide hole 30, thereby realizing the opening and closing of the guide hole 30; when it is not necessary to discharge the medicine, it is only necessary to release the pressing piece 41, and the spring piece 42 will automatically rebound, so that the arc contact shoe 43 will fit with the guide hole 30 again to close the guide hole.

[0055] Furthermore, the spring piece 42 is located inside the sliding sleeve; one end of the spring piece 42 is fixed to the hard pipe section 3, and the other end is fixedly connected to the pressing piece 41. Because the spring piece 2 is always in an expanded state under normal conditions, a large friction force is generated between the sliding sleeve and the hard pipe section 3, preventing the sliding sleeve from falling off the hard pipe section 3.

[0056] Furthermore, the arc contact shoe 43 has a semicircular groove, through which it contacts the hard pipe section 3; the semicircular groove can fit tightly against the outer wall of the hard pipe section 3, thereby better sealing the guide hole 30.

[0057] In general, if Figure 2 and Figure 4 The sliding sleeve and the support seat 40 are both located inside the storage tube 2 and are not in direct contact with the outside, with a higher level of sanitary protection. The support seat 40 is a porous structure so that the medicine discharged from the guide hole can quickly flow into the storage tube 2 through the support seat.

[0058] Obviously, the support base 40 has connecting portions on both sides, which are fixed to the rigid pipe section 2 through these connecting portions, and is equivalent to a part of the rigid pipe section. The cross-section of the support base 40 is a C-shaped structure, and the arc contact shoe 43 is located within this C-shaped structure. The support base 40 acts as a limit for the arc contact shoe 43, preventing the sliding sleeve from swinging and falling off.

[0059] In addition, the intravenous infusion tube drug emergency discharge device of the present invention has low production cost, is small and exquisite, has a compact structural design, stable finished product quality, and is easy to operate. It is suitable for various modified infusion tubes and intravenous drug injection devices during surgery.
