Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical equipment, in particular to a bladder irrigation injection pump. BACKGROUND

[0002] Bladder irrigation is an important operation in clinical nursing for maintaining bladder function, preventing and treating related diseases, and its core purpose is to remove foreign matter in the bladder through liquid circulation, reduce the risk of infection and promote disease recovery. Among them, the incidence of urinary tract infection in patients with long-term indwelling catheter is high, and irrigation of the bladder can effectively reduce the probability of bacterial colonization. Blood clots are easily formed in the bladder after urological surgery, and irrigation of the bladder can prevent catheter blockage and reduce the risk of secondary surgery.

[0003] In clinical nursing, a bladder irrigation device is used to irrigate the bladder of a patient. In operation, the output end of the irrigation device is first placed into the catheter or bladder, and the internal irrigation liquid is slowly delivered to the bladder by the irrigation device to irrigate the bladder. After the irrigation is completed, the mixed irrigation liquid after irrigation is extracted from the bladder by using the liquid extraction function of the irrigation device, and finally the mixed irrigation liquid in the irrigation device is poured into a waste collection container. The above steps are repeated until the extracted mixed irrigation liquid becomes light pink or clear irrigation liquid. Although this type of bladder irrigation device can complete the bladder irrigation, the liquid injection function and the liquid extraction function of the device are independent of each other. When in use, the irrigation liquid for irrigating the bladder is first injected into the patient's bladder, and then the liquid extraction function of the irrigation device is turned on to extract the waste liquid. In clinical application, some patients are in bed for a long time and have a catheter. In the daily state, the urine in the bladder will be discharged from the catheter to the urine bag, and the bladder is always in an empty state, losing the expansion and urine storage state similar to daily life. Prolonged use of the irrigation device to inject irrigation liquid into the patient's bladder cannot real-time grasp the maximum tolerable state of the irrigation liquid after the bladder is expanded, and the entire injection process is in a non- visible state. Once the operation is wrong, the patient's bladder is easily damaged by injecting too much irrigation liquid into the bladder. Therefore, the irrigation device has certain safety hazards in clinical application. SUMMARY

Thus, the harm caused by the instantaneous expansion of the bladder of the patient can be effectively reduced.

[0020] Secondly, the lifting drive of the drainage plate arranged in the flushing chamber can compress the space of the upper and lower two regions of the inside of the flushing chamber, and the blocking function of the stopper to the extension pipeline can form a negative pressure or a positive pressure state in the upper and lower two regions of the flushing chamber. Thus, the waste liquid in the bladder of the patient can be extracted at the same time as the new flushing liquid is guided into the flushing chamber for subsequent injection into the bladder to complete the flushing. At the same time, the waste liquid after flushing can be removed, so that the one-way operation of the drainage plate can achieve a bidirectional effect, and the safety hazard caused by the excessive expansion of the bladder due to the instantaneous filling of the flushing liquid can be further avoided.

[0021] Thirdly, the flushing port and the suction port arranged in the flushing pipeline can be used as channels for guiding the flushing liquid and the waste liquid. The suction port and the flushing port are arranged separately at the front end of the flushing pipeline, so that the flushing liquid can be discharged from the flushing port at the front end of the flushing pipeline and can flush along the inner wall of the bladder, and the suction port at the front end of the flushing pipeline can provide a channel for immediately extracting the flushing liquid injected into the bladder.

[0039] In order to make the objects, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be described below in connection with specific embodiments of the present application and corresponding drawings. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0040] The technical solutions provided by the embodiments of the present application will be described in detail below in connection with the drawings.

[0041] The embodiment of the present application provides a bladder irrigation injection pump, which comprises a casing 1; an irrigation bin 11, a water storage bin 12 for storing irrigation liquid and a waste liquid bin 13 for collecting waste liquid generated after bladder irrigation are arranged in the casing 1; an adjuster 2 for controlling injection of irrigation liquid into the bladder of a patient and extraction of waste liquid is arranged on the irrigation bin 11; one side of the irrigation bin 11 is in communication with the water storage bin 12 and the waste liquid bin 13; the other side of the irrigation bin 11 is in communication with an irrigation pipeline 3 for delivering liquid into the bladder of the patient and extracting liquid; a controller for driving and controlling the adjuster 2 is arranged on the casing 1, and the controller and the adjuster 2 are provided with a matched power supply system which can be connected by a wired circuit to maintain the driving force of the controller and the adjuster 2;

[0042] The water storage bin 12 and the waste liquid bin 13 in the present application are both prior art, wherein the water storage bin 12 can be used for storing irrigation liquid for bladder irrigation of a patient, and the waste liquid bin 13 is used for collecting mixed waste liquid generated after irrigation liquid is injected into the bladder to complete irrigation; the top ends of the water storage bin 12 and the waste liquid bin 13 are provided with liquid adding ports and discharge ports extending to the outside of the casing 1, so as to facilitate irrigation liquid supplement in the water storage bin 12 and waste liquid discharge and cleaning in the waste liquid bin 13;

[0043] When it is necessary to flush the bladder of a patient, the flushing pipeline 3 can be placed in the bladder of the patient, and then the controller is operated to drive the regulator 2 to perform a driving instruction operation, so that the regulator 2 performs a negative pressure state switching operation on the inside of the flushing chamber 11, so that the inside of the flushing chamber 11 drains the flushing liquid in the water storage chamber 12 into the chamber of the flushing chamber 11, and the regulator 2 performs a negative pressure state switching operation on the flushing chamber 11, so that the flushing liquid injected into the flushing chamber 11 can be transported into the flushing pipeline 3 and discharged into the bladder of the patient, and the inside of the flushing chamber 11 can extract the flushing liquid discharged into the bladder of the patient and discharge it into the flushing chamber 11 when the negative pressure state is switched, and the negative pressure state in the flushing chamber 11 is switched again during the subsequent operation of the regulator 2, so that the waste liquid extracted from the bladder can be discharged into the waste liquid chamber 13, and the flushing chamber 11 can again drain the flushing liquid in the water storage chamber 12 into the flushing chamber 11, so as to simultaneously transport the flushing liquid into the bladder of the patient and extract the waste liquid after flushing the bladder, and simultaneously discharge the waste liquid in the flushing chamber 11 and again drain the flushing liquid in the water storage chamber 12 into the flushing chamber 11, thereby facilitating secondary flushing of the bladder, so that the flushing liquid can be extracted at the same time as flushing the bladder, and the waste liquid can be discharged in time. Since the prior art injects flushing liquid into the bladder of the patient, the inside of the bladder of the patient expands like urine retention, and when the flushing liquid is transported into the bladder multiple times, the bladder of the patient expands multiple times in a moment, which can easily cause damage to the patient, and the body organ perception ability of some elderly and long-term bedridden patients decreases, and if the expansion of the bladder of the patient is not timely feedback to medical staff, greater safety hazards can be caused. Therefore, the present application can simultaneously flush the bladder of the patient and remove the waste liquid after flushing, so that the bladder of the patient does not expand in a moment, thereby effectively reducing the damage caused by the momentary expansion of the bladder of the patient.

[0044] In further preferred embodiments of the application, with reference to the accompanying drawings, Figure 4 As shown in the drawings, the flushing chamber 11 is in a cylindrical structure; a support is arranged at the bottom of the flushing chamber 11 to support the entire flushing chamber 11; and a chamber for storing liquid is arranged in the inside of the flushing chamber 11.

[0048] In the further preferred embodiment of the present application, referring to the accompanying drawings Figures 1 to 3 As shown, the water injection pipeline 14, the water suction pipeline 15, the waste liquid extraction pipeline 16 and the waste liquid discharge pipeline 17 are all provided with a drainage pipeline 33; the two ends of the drainage pipeline 33 on the water injection pipeline 14 are in communication with the water injection pipeline 14 and the flushing port 32 at the terminal end of the flushing pipeline 3; the two ends of the drainage pipeline 33 on the water suction pipeline 15 are in communication with the water suction pipeline 15 and the water outlet port of the water storage chamber 12; the two ends of the drainage pipeline 33 on the waste liquid extraction pipeline 16 are in communication with the waste liquid extraction pipeline 16 and the suction port 31 at the terminal end of the flushing pipeline 3; the two ends of the drainage pipeline 33 on the waste liquid discharge pipeline 17 are in communication with the waste liquid discharge pipeline 17 and the water injection port of the waste liquid chamber 13;

[0049] The flushing port 32 and the suction port 31 arranged in the flushing pipeline 3 are used as channels for draining the flushing liquid and the waste liquid, and the suction port 31 and the flushing port 32 are separately arranged at the front end of the flushing pipeline 3, so that the flushing liquid can be flushed along the inner wall of the bladder after being discharged from the flushing port 32 at the front end side wall of the flushing pipeline 3, and the suction port 31 at the front end of the flushing pipeline 3 can provide a timely extraction channel for the flushing liquid injected into the bladder.

[0059] Referring to FIG. 1 Figure 7 Before the patient's bladder needs to be flushed, the controller needs to be operated to run the lifting electric cylinder, so that the driving end of the lifting electric cylinder drives the support 23 to descend by a distance, and the adjusting members 24 on both sides of the support 23 drive the corresponding flow-stopping plugs 41 to descend, wherein, since the spring 44 is arranged on each flow-stopping rod 42, the two flow-stopping plugs 41 on the adjusting member 24 on the left side of the support 23 will be pushed downward by the spring 44 at all times, and with the descent of the support 23, the two flow-stopping plugs 41 on the adjusting member 24 on the left side of the support 23 will immediately be inserted into the bottom of the extension pipe 18, and until the bottom of the two flow-stopping plugs 41 contacts the inner wall part of the water injection pipe 14 and the waste liquid extraction pipe 16 at the bottom end of the extension pipe 18, so that the flow-stopping plugs 41 can block the extension pipe 18 part on the water injection pipe 14 and the waste liquid extraction pipe 16, so as to block the flow state between the water injection pipe 14 and the waste liquid extraction pipe 16 and the inside of the flushing chamber 11;

[0060] The two stop plugs 41 on the right side adjusting member 24 of the support 23 are limited in their maximum travel distance by the stop blocks 43 provided on the respective stop rods 42, so that when the support 23 is lowered, the two stop plugs 41 on the right side adjusting member 24 of the support 23 will not remain in the water inlet pipe 14 and the waste liquid discharge pipe 17 due to the continuous pushing force of the spring 44. In order to ensure that the flushing chamber 11 can store enough flushing liquid for one bladder flushing, the length of the drain plate 21 that can be lifted in the flushing chamber 11 in this patent application is greater than the length of the extension pipe 18, so that the stop plugs 41 and the adjusting member 24 can not normally lift and move due to the excessive length of the extension pipe 18. At the same time, since the length of the extension pipe 18 is limited, when the bottom of the stop plug 41 first contacts the inner bottom of the extension pipe 18 on the water inlet pipe 14 and the waste liquid extraction pipe 16, the stop rod 42 is designed to slide up and down with the adjusting member 24, so that the stop plug 41 can be pushed by the spring 44 to resist the inner bottom of the extension pipe 18 on the water inlet pipe 14 and the waste liquid extraction pipe 16. The upper half of the top end stop rod 42 can pass out of the adjusting member 24 by a certain distance, so as to prevent the stop plug 41 from being damaged due to excessive compression in the water inlet pipe 14 and the waste liquid extraction pipe 16 when the drain plate 21 needs to be lowered greatly;

[0061] When the water inlet pipe 14 and the flushing chamber 11 are in a closed flow state, and the parts between the water extraction pipe 15 and the waste liquid discharge pipe 17 and the respective extension pipes 18 are not blocked by the stop plugs 41, the water extraction pipe 15 and the waste liquid discharge pipe 17 are in a normal flow state. When the drain plate 21 is lowered, the upper area of the drain plate 21 will form a negative pressure state in the upper half of the flushing chamber 11, so that the negative pressure airflow in the upper half of the flushing chamber 11 will attract the inside of the water extraction pipe 15 and the drainage pipe 33, so as to suck the flushing liquid in the water storage chamber 12 into the upper half area of the flushing chamber 11 separated by the drain plate 21. Secondly, due to the lowering of the drain plate 21, the lower half of the flushing chamber 11 is compressed by the drain plate 21. Since the waste liquid extraction pipe 16 and the flushing chamber 11 are in a closed flow state, and the waste liquid discharge pipe 17 and the flushing chamber 11 are in an open flow state, when the drain plate 21 compresses the lower half of the flushing chamber 11, the internal air will be squeezed out of the flushing chamber 11 through the waste liquid discharge pipe 17, so that the lower half of the flushing chamber 11 is in a compressed idle state, which facilitates the subsequent temporary storage of the waste liquid generated after flushing the bladder.

[0062] After the above operation steps are completed, the initial stage flushing liquid filling work in the upper half of the flushing chamber 11 can be realized.

[0063] Referring to the drawings Figure 8 As shown in the process of bladder irrigation, the front end of the irrigation pipeline 3 is placed in the patient's bladder, and then the controller is operated again to drive the drive end of the lifting cylinder to operate, so that the support 23 rises and drives the two adjusting members 24 on both sides to rise. At this time, the adjusting member 24 on the left side of the support 23 drives the corresponding two stop plugs 41 to move upward from the extension pipeline 18, and under the limiting action of the end block 43 of each stop plug 42, the stop plug 41 cannot continue to move downward due to the pushing force of the spring 44, and the bottom of the two stop plugs 41 is removed from the state of resisting the inner wall part of the water injection pipeline 14 and the waste liquid extraction pipeline 16 at the bottom end of the extension pipeline 18, and with the rising of the two stop plugs 41, the water injection pipeline 14 and the waste liquid extraction pipeline 16 will be re-opened with the flushing bin 11. The state of flow; while the two stop plugs 41 of the support 23 on the right side of the support 23 will be placed at the top of the extension pipeline 18 under the pushing force of the respective spring 44, and will be placed at the top of the extension pipeline 18 until the top of the two inverted state stop plugs 41 on the right side of the support 23. The adjusting member 24 forms a resistance to the inner part of the water extraction pipeline 15 and the waste liquid discharge pipeline 17 at the top end of the extension pipeline 18, so as to block the flow state of the water extraction pipeline 15 and the waste liquid discharge pipeline 17 in the flushing bin 11. With the support 23 driving the drain plate 21 to continue to rise by a distance, the spring 44 between the two stop plugs 41 on the right side of the support 23 and the adjusting member 24 will shrink due to pressure, and the bottom of the two stop plugs 41 will be inserted into the adjusting member 24, so as to avoid damage to the two stop plugs 41 due to excessive compression;

[0064] With the water injection pipeline 14 and the waste liquid extraction pipeline 16 being in a flow open state with the inside of the flushing bin 11, and the water extraction pipeline 15 and the waste liquid discharge pipeline 17 being in a flow closed state with the inside of the flushing bin 11, when the drainage plate 21 rises, the upper part of the drainage plate 21 will squeeze the upper half of the flushing bin 11, and the flushing liquid temporarily stored in the upper half of the flushing bin 11 will be squeezed out of the water injection pipeline 14, and then transported to the flushing port 32 in the flushing pipeline 3 through the drainage pipeline 33, and then discharged from the front end of the flushing pipeline 3, so as to flush the patient's bladder; at this time, the lower part of the drainage plate 21 will be in a negative pressure state due to the rising of the drainage plate 21, so that the negative pressure airflow formed in the lower half of the flushing bin 11 will attract the waste liquid extraction pipeline 16 and the drainage pipeline 33, so as to suck the waste liquid generated after flushing in the bladder from the front end of the flushing pipeline 3 through the suction port 31 in the flushing pipeline 3, and then perform synchronous flushing and waste liquid removal operation on the inside of the bladder, so that the inside of the bladder can be cleaned after a certain amount of flushing liquid is injected for flushing, so as to avoid overexpansion of the bladder due to single over-injection of flushing liquid, effectively prevent the patient's bladder from expanding like holding urine due to instantaneous liquid filling, and avoid damage to the patient's bladder caused by frequent instantaneous expansion state due to multiple delivery of flushing liquid into the bladder; secondly, in clinical application, since the bladder flushing is in a non-visible state, it is difficult for medical staff to master the injection of flushing liquid into the patient's bladder by relying on feeling operation, and one-time over-injection of flushing liquid is easy to cause damage to the patient's bladder due to instantaneous overexpansion, and part of the long-term bedridden elderly patients may not be able to timely feedback the state of the bladder after expansion to the medical staff due to the decline of their own organ perception ability, and the whole operation process will undoubtedly cause multiple damage to the bladder of such patients, and once the bladder is damaged, it will affect the whole urinary system of the patient, and in serious cases, it may even lead to more serious medical accidents such as rupture of the bladder and urethra, therefore, the present application can realize the injection and synchronous extraction operation of the flushing liquid in the patient's bladder during use, so that the patient's bladder will not be overexpanded due to over-injection of flushing liquid, and the damage caused by overexpansion of the patient's bladder can be effectively prevented, and the use experience is safer in clinical application.

Those skilled in the art can make various changes and modifications to the present application. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application shall be included in the scope of the claims of the present application.
