Description

Technical Field

[0001] The present application relates to the technical field of punching and sealing tubes, and in particular to an automatic drug injection and punching and sealing tube device capable of adding drugs. Background Art

[0002] In modern medical practice, double-lumen and multi-lumen catheters play a vital role in clinical treatment due to their ability to provide multi-channel venous access. These catheters are widely used in patients requiring long-term intravenous infusion, hemodialysis, intensive care, and blood product transfusion. They allow medications and blood products to be delivered simultaneously or independently without the need for multiple punctures, reducing patient discomfort and the risk of infection. However, according to the "Technical Operation Guidelines for Intravenous Therapy Nursing" and the "Standards of Infusion Therapy Practice" of the American Academy of Intravenous Nursing, even if only a single lumen is used, all lumens must be flushed and sealed after use to prevent catheter clogging.

[0003] In clinical practice, a double-chamber syringe is generally used to flush and seal the lumen. Medical staff use the fish muscle to control the double-chamber syringe with a "push-stop-push" technique. Each push is used to seal the tube with a positive pressure of 0.5-1 ml. After the remaining 0.5-1 ml of the double-chamber syringe is filled, the two chambers are pushed straight at the same time.

[0004] While existing dual-chamber syringes offer significant advantages over single-chamber syringes in clinical applications, they rely on manual operation by nursing staff, requiring not only a high degree of coordination and precision but also the potential for muscle damage from prolonged manual operation. Furthermore, they lack flexibility, hindering convenient addition of medication to the injection chamber when necessary, and inefficient flushing and sealing of the tube. Utility Model Content

[0038] In addition, the technical features involved in the different embodiments of the present invention described above can be combined with each other as long as they do not conflict with each other.

[0039] The utility model provides Figures 1 to 4 As shown in the figure, an automatic drug injection and sealing tube device capable of adding drugs is intended to solve the shortcomings of the existing double-chamber syringe 100 that cannot automatically push the tube and add drugs.

[0040] The automatic drug injection, flushing, and sealing device for adding medication primarily comprises a dual-chamber syringe 100, two drug adders 200, and a tube pusher 300. The dual-chamber syringe 100 has two injection chambers 111 for containing injection liquid, and the two drug adders 200 are connected to the two injection chambers 111, respectively, for placing medication. Specifically, pushing the dual-chamber syringe 100 enables its two nipples to simultaneously flush and seal the tube. Compared to using two conventional single-chamber syringes for flushing and sealing the tube, this avoids the effects of different injection volumes caused by uneven force applied to the two single-chamber syringes.

[0041] In actual use, conventional physiological saline or heparinized saline can be used for flushing and sealing the lumen. Heparinized saline is a dilution formed by diluting sodium heparin injection with physiological saline. Conventional physiological saline can be converted to heparinized saline by injecting an appropriate amount of sodium heparin injection into the drug adding device 200. Specifically, different drugs can be added to the drug adding device 200 according to actual needs, so that the injection cavity 111 and the drugs in the drug adding device 200 mix to form the desired drug.

[0042] The tube pusher 300 is detachably connected to the dual-chamber syringe 100 and is used to drive the dual-chamber syringe 100 for injection. Specifically, the tube pusher 300 can drive the dual-chamber syringe 100 for injection by elastic potential energy drive, electric drive, or other methods, and can drive the dual-chamber syringe 100 for injection in a continuous or intermittent manner to meet the actual needs of medical personnel. Moreover, by detachably connecting the tube pusher 300 to the dual-chamber syringe 100, the dual-chamber syringe 100 can be set up once. After use, the tube pusher 300 can be separated from the dual-chamber syringe 100 and the dual-chamber syringe 100 can be discarded, while the tube pusher 300 can be reused, saving usage costs.

[0043] Although the existing dual-chamber syringe 100 has significant advantages over single-chamber syringes in clinical applications, its operation relies on manual manipulation by nursing staff, which not only requires a high degree of coordination and precision, but also can cause hand muscle damage due to prolonged manual manipulation. Furthermore, it lacks flexibility, making it difficult to conveniently add medication to the injection chamber 111 when necessary, and its efficiency in flushing and sealing the tube is low.

[0044] The utility model provides a tube pusher 300 and a medicine adding device 200, so that the double-chamber syringe 100 can push the tube under the drive of the double-chamber syringe 100, realize automatic tube flushing and sealing or injection, and during use, the same or different drugs can be added to the two injection chambers 111 through the two medicine adding devices 200 respectively connected to the two injection chambers 111, so as to flexibly meet the usage needs of medical staff in different scenarios.

[0045] In some embodiments, as Figures 1 to 3 As shown in FIG, the dual-chamber syringe 100 further includes: a syringe body 110 , two pistons 120 and two push rods 130 .

[0046] Two injection chambers 111 are provided on the syringe body 110, which is provided with two injection grooves. Two pistons 120 are respectively disposed within the two injection grooves, forming two injection chambers 111 between the two pistons 120 and the two injection grooves. Two push rods 130 are respectively connected to the two pistons 120. The two push rods 130 are driven to move linearly along their axial directions, thereby driving the two pistons 120 toward the bottoms of the two injection grooves.

[0047] Specifically, by pushing the two push rods 130 , the two pistons 120 are driven to move toward the bottoms of the two injection grooves respectively, so that the volumes of the two injection cavities 111 become smaller, thereby achieving the injection action.

[0048] In some embodiments, as Figures 1 to 3 As shown in FIG, the medicine adding device 200 includes a medicine adding cavity 210 , a medicine adding hole and a rubber plug 220 .

[0049] The drug adding device 200 is disposed on the syringe body 110. The drug adding cavity 210 is connected to the end of the corresponding injection groove away from the groove bottom. The drug adding hole is disposed on the drug adding cavity 210 and is connected to the drug adding cavity 210. The drug adding hole is used to insert the drug. During actual use, the piston 120 is first moved toward the end away from the groove bottom, so that the drug adding cavity 210 is connected to the injection cavity 111. At this time, the drug can be placed / injected into the drug adding cavity 210 through the drug adding hole. Since the drug adding cavity 210 is connected to the end of the corresponding injection groove away from the groove bottom, the drug can enter the injection groove from the end of the injection groove away from the groove bottom. Since the nipple of the dual-chamber syringe 100 is close to the groove bottom, it can prevent the drug from entering the injection cavity 111 from the drug adding cavity 210 directly reaching the vicinity of the nipple, resulting in an excessively high concentration of the injected drug solution. This also facilitates medical personnel to shake multiple drugs evenly.

[0050] The plug 220 is removably disposed within the medicine-adding hole and is used to seal the hole. Specifically, the plug 220 prevents the medicine-adding cavity 210 from being directly connected to the outside world. The plug 220 is separated from the medicine-adding cavity 210, thereby facilitating the insertion of solid medicine. Alternatively, another syringe can be used to directly puncture the plug 220 and inject liquid medicine directly into the medicine-adding cavity 210.

[0051] In some embodiments, as Figures 1 to 3 As shown in , the medicine adding device 200 also includes: a connecting hole 230, which is provided on the syringe body 110, and is connected to the end of the corresponding injection groove away from the bottom of the groove. The medicine adding cavity 210 is connected to the corresponding injection groove through the connecting hole 230. In actual use, the piston 120 is first moved toward the end away from the bottom of the groove so that the connecting hole 230 is connected to the injection cavity 111. At this time, the medicine can be put into / injected into the medicine adding cavity 210 through the medicine adding hole. Since the connecting hole 230 is connected to the end of the corresponding injection groove away from the bottom of the groove, the medicine can enter the injection groove from the end of the injection groove away from the bottom of the groove. Since the nipple of the double-chamber syringe 100 is close to the bottom of the groove, it can prevent the medicine from directly reaching the vicinity of the nipple when entering the injection cavity 111 from the medicine adding cavity 210, resulting in too high a concentration of the injected medicine. It also makes it convenient for medical staff to shake multiple medicines evenly.

[0052] The width of the two pistons 120 in the axial direction of the push rod 130 is not less than the width of the corresponding connecting hole 230 in the axial direction of the push rod 130. Figure 2As shown in the figure, the width of the two pistons 120 in the axial direction of the push rod 130 is represented by a, and the width of the connecting hole 230 in the axial direction of the push rod 130 is represented by b. When the medical staff pushes the piston 120 to move, if a < b, it will cause the part of the connecting hole 230 away from the bottom of the groove to communicate with the outside during the process of pushing the piston 120. If the part of the connecting hole 230 facing the bottom of the groove is connected to the injection cavity 111 at this time, it will cause the injection cavity 111 to communicate with the outside, resulting in "liquid leakage", and the liquid medicine in the injection cavity 111 will spray out from the opening away from the bottom of the groove. If a ≥ b, the situation of "liquid leakage" will not occur.

[0053] In some embodiments, as Figures 1 to 3 shown in the figure, the distance between the two connecting holes 230 and the openings of the corresponding injection grooves is not less than the width of the corresponding piston 120 in the axial direction of the push rod 130. For the sake of convenience of description, as Figure 2 shown in the figure, the distance between the two connecting holes 230 and the openings of the corresponding injection grooves is represented by c, and the width of the piston 120 in the axial direction of the push rod 130 is a. If c < a, it will cause the piston 120 to block the connecting hole 230, which is not conducive to adding medicine.

[0054] In some embodiments, as Figures 1 to 4 shown in the figure, the pusher 300 includes: a fixing part 320, a movable part 330 and a driver 340.

[0055] The fixing part 320 is clamped with the syringe body 110. The movable part 330 is separated from the fixing part 320. One end of the push rod 130 away from the two pistons 120 is connected to form a pushing part 131, and the movable part 330 is clamped with the pushing part 131. The driver 340 is arranged on the fixing part 320, and the driver 340 is used to drive the movable part 330 to move to change the distance between the movable part 330 and the fixing part 320.

[0056] Specifically, the driver 340 changes the distance between the movable part 330 and the fixing part 320, and further changes the distance between the piston 120 and the bottom of the injection groove. By reducing the distance between the movable part 330 and the fixing part 320, the distance between the piston 120 and the bottom of the injection groove can be reduced, so that the volume of the two injection cavities 111 becomes smaller, thereby realizing the injection action.

[0057] In some embodiments, as Figures 1 to 4 shown in the figure, the pusher 300 further includes: a slide rail 310. The slide rail 310 is parallel to the two push rods 130 respectively. The slide rail 310 is arranged on the fixing part 320, and the movable part 330 is slidably arranged on the slide rail 310, and the movable part 330 is driven by the driver 340 to slide on the slide rail 310.

[0058] In some embodiments, as Figures 1 to 4As shown in , the fixing portion 320 includes: a limiting groove 321, and the syringe body 110 is engaged with the limiting groove 321;

[0059] The movable portion 330 includes a plate 331 , the plate 331 abutting against the pushing portion 131 ;

[0060] The driver 340 is a screw stepping motor, the movable portion 330 is in transmission connection with the screw stepping motor, and the movable portion 330 is driven by the screw stepping motor to move toward or away from the fixed portion 320 .

[0061] In some embodiments, the pipe pusher 300 further includes a timer. The timer and the driver 340 are spaced apart on the slide rail 310 , and the timer is electrically connected to the driver 340 .

[0062] Specifically, the timer can record the actual operation of the driver 340, thereby enabling the driver 340 to operate at a constant speed, a variable speed, or intermittently (pulsed) operation. For example, the driver 340 can replace the medical staff's "push-stop-push" technique during the tube sealing operation, saving manpower and material resources.

[0063] In some embodiments, as Figure 3 As shown in , the pipe pusher 300 further includes: a control panel 350, the control panel 350 is disposed on the slide rail 310, and the control panel 350 is electrically connected to the timer;

[0064] The control panel 350 includes: a uniform speed push button, a pulse push button, and a time setting button.

[0065] Specifically, the operating mode (constant speed, variable speed, and intermittent) of the driver 340 can be adjusted through the control panel 350 .

[0066] In summary, an automatic drug injection, flushing and sealing tube device capable of adding drugs is provided, comprising a double-chamber syringe, two drug adders and a tube pusher. The double-chamber syringe has two injection chambers, the two injection chambers are used to accommodate injection liquids, the two drug adders are respectively connected to the two injection chambers, the two drug adders are used to place drugs, the tube pusher is detachably connected to the double-chamber syringe, and the tube pusher is used to drive the double-chamber syringe for injection.

Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible.
