Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to a flushing liquid heating device. Background Art

[0002] During prostatectomy, a large amount of normal saline is used to flush the bladder. Generally, more than ten or twenty bags of 3000ml bagged normal saline are used. Due to the large amount of usage, patients are prone to hypothermia during surgery. Therefore, it is most appropriate to heat the flushing fluid to a temperature between 37-41 degrees. If an incubator is used for heating, the incubator is large in size and inconvenient to place. In addition, the temperature is easy to drop during use, and a better insulation effect cannot be achieved. In addition, there is an infusion thermostat on the market that can clamp the pipeline in the thermostat to heat the liquid. The patient experience is better, but the infusion thermostat is used for bladder flushing. The following disadvantages exist in the pipeline: during bladder irrigation, it is sometimes necessary to turn off the regulator to prevent the liquid from flowing, and when the liquid stops flowing, the operator needs to manually turn off the infusion thermostat. Manual closing or opening is troublesome and it is easy to forget to turn it off. If you forget to turn off the thermostat, the thermostat will continue to heat the pipeline, causing the temperature of the medicine or flushing fluid in the pipeline to rise. After the regulator is turned on, the heated medicine or flushing fluid has the risk of scalding the patient's bladder. In addition, when some medicines are heated to too high a temperature, the medicinal properties will change, and even affect the patient's health. Therefore, it is necessary to design a new type of flushing fluid heating device. Utility Model Content

[0003] In view of the above situation, in order to overcome the defects of the prior art, the purpose of the present invention is to provide a flushing liquid heating device, which effectively solves the problems of poor heating effect on the flushing pipeline and inconvenience in use of the prior art devices.

[0017] In order to enable the slide plate 2 to slide on the mounting plate 1 , an inverted L-shaped groove 10 with an opening facing left is provided on the rear side of the mounting plate 1 , and the right side of the slide plate 2 is inverted L-shaped and is slidably connected to the inverted L-shaped groove 10 .

[0018] In order to fix the slide plate 2 on the regulator 19 of different models of infusion pumps, the slide plate 2 is provided with a plurality of positioning holes 11 distributed in the left and right directions and passing through the upper and lower parts. The mounting plate 1 is slidably connected with an upper and lower axial and T-shaped positioning rod 12. The lower end of the positioning rod 12 can be inserted into the corresponding positioning hole 11. The stepped surface of the positioning rod 12 is connected to the upper end surface of the mounting plate 1 via a tension spring.

[0019] In order to improve the heat preservation effect of the flushing pipeline, heat preservation cotton layers 13 are fixed on the front and back sides of the inner surface of the lower arc groove and the inner surface of the upper arc groove respectively.

[0020] In order to prevent the flushing pipeline from slipping out of the two arc-shaped grooves, a downward-opening slot 14 is provided on the front side of the upper clamping plate 7, and a clip 15 that can cooperate with the slot 14 is fixed on the front side of the lower clamping plate 8, and the clip 15 can produce slight deformation.

[0021] A rechargeable battery 16 is installed in the mounting plate 1, and a USB interface 17, an indicator light and a switch 18 are provided on the mounting plate 1. The main contact 4, the auxiliary contact 6, the battery 16, the indicator light, the switch 18, the USB interface 17 and the constant temperature chip are all electrically connected.

[0022] When the utility model is in use, the auxiliary contact 6 is set to contact the main contact 4 under the action of the compression spring, the clamping strip 15 is clamped in the clamping groove 14, that is, the upper clamping plate 7 and the lower clamping plate 8 are connected together, and the regulator 19 is set to be open, that is, the initial state of the maximum flow rate of the flushing liquid;

[0023] The medical staff holds the mounting plate 1 and pries the lower splint 8 downward. The card strip 15 is deformed by the squeeze of the side wall of the card slot 14 and comes out of the card slot 14. The lower splint 8 is out of contact with the upper splint 7. The opening between the two arc grooves is opened, and the left end of the mounting plate 1 is in contact with the right end of the regulator 19. The left end of the T-bar 5 is inserted into the through groove on the right side of the regulator 19. The T-bar 5 is located above the flushing tube, and the flushing tube is located between the lower splint 8 and the upper splint 7. The positioning rod 12 is pulled upward to adjust the position of the slide plate 2, and the hook shape of the left end of the slide plate 2 is hooked into the through groove on the left side of the regulator 19. After the inner part of the hook shape on the slide plate 2 contacts the left side of the regulator 19, the positioning rod 12 is operated to be inserted into the corresponding positioning hole 11, and the mounting plate 1 is fixed on the regulator 19.

[0024] The lower splint 8 is swung upward, and the clip 15 on the lower splint 8 is inserted into the clip groove 14. The lower splint 8 and the upper splint 7 fix the flushing pipe therein, and the heat-insulating cotton layer 13 wraps the flushing pipe. The switch 18 is turned on, and the constant temperature heating chip 9 starts heating. The indicator light comes on, and the heat is transferred to the heat-insulating cotton layer 13 and the flushing pipe, heating the flushing liquid in the flushing pipe and keeping the temperature of the flushing liquid between 37 and 41 degrees Celsius. This increases the comfort of the patient during bladder flushing and avoids discomfort such as hypothermia.

[0025] When the medical staff needs to stop the flow of the flushing liquid, they roll the roller 20 on the regulator 19 to the right. The roller 20 rolls to the right and gradually squeezes the flushing tube. When the flushing tube is completely squeezed and closed by the roller 20, the roller 20 squeezes the T-shaped rod 5 on the right. At this time, the T-shaped rod 5 drives the auxiliary contact 6 to move to the right and squeezes the compression spring, so that the auxiliary contact 6 and the main contact 4 are disengaged, the circuit is disconnected, the indicator light is off, the constant temperature heating chip 9 no longer heats up, and the flushing tube is no longer heated, effectively preventing the liquid from being heated when it is not flowing, and the patient from being scalded.

[0026] When the regulator 19 needs to be opened, the roller 20 is rolled to the left, and the flushing tube is gradually not squeezed, that is, the liquid flows. At the same time, the T-bar 5 is not squeezed by the roller 20. Under the action of the compression spring, the T-bar 5 drives the auxiliary contact 6 and the main contact 4 to attract, and the circuit is connected. The constant temperature heating chip 9 starts to heat the liquid in the flushing tube.

[0027] In the present invention, the main contact 4, the auxiliary contact 6, the battery 16, the switch 18, the USB interface 17 and the thermostat chip are all electrically connected, and the connection method adopts the existing technology, which will not be described in detail here.

[0028] The regulator 19 in the present invention is the existing technology, and the roller 20 thereon has many grooves. When the flushing pipe is squeezed, the roller 20 will not roll accidentally due to the effect of friction. Moreover, when the roller 20 completely closes the flushing pipe, the pressure after the compression spring is compressed will not cause the roller 20 in this state to roll accidentally.
