Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a constant temperature enema. Background Art

[0002] Enteral drug administration has been used in my country for a long time. Clinically, drugs are instilled into the anus, retained in the rectum or colon, and absorbed through the intestinal mucosa to achieve the purpose of sedation, hypnosis and intestinal sterilization. There are many factors that affect the efficacy of enema. In addition to the technique, drug selection, depth, and treatment frequency, the temperature of the drug solution also has an important influence on the efficacy. Clinically, there are also requirements for temperature according to different treatment purposes. For example, the temperature of the drug solution used for enema in patients with ulcerative colitis is 37.0-38.9℃, which is close to the rectal temperature. At present, most enema devices can only keep the heated drug solution warm, but do not have a heating function.

[0003] The invention patent application with publication number CN117504034A (enema device with temperature control function and method of use thereof) has the function of heating the drug solution. However, the heating device used in this technical solution only heats the drug solution flowing through the heated drug delivery tube, and does not heat the drug solution in the drug solution bag, which places high requirements on the temperature control of the heating device. In addition, the heated drug delivery tube is a special component, which is not convenient to replace and is difficult to meet the requirements of disposable use. Utility Model Content

[0016] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0017] A constant temperature enema device, the main body of which is a rectangular box-shaped device with a partition and a peristaltic pump, including a box body, a temperature control device and an adjustable peristaltic pump. The box body is equipped with a detachable perforated partition, and the inner wall of the box body is provided with slots, which can be used to divide and adjust the space in the box body according to the different drug liquid containers and catheters used. The temperature control device can heat and control the temperature of the water bath liquid in the box body according to needs, and heat the drug liquid in the drug liquid container and catheter placed inside the box body by means of a water bath. The peristaltic pump can adjust the flow rate according to the use requirements, and the pump is equipped with an adjustment device, which can be adjusted according to the diameter of the catheter used.

[0018] This device is designed to control the temperature and heat the liquid medicine containers (such as syringes, enema bags, etc.) and the liquid medicine in the catheter commonly used in clinical practice. The liquid medicine containers and catheters of the equipment can be stored separately through the partition inside the box. The catheter can be coiled in the compartment, and the size of the compartment can be adjusted according to the specifications of the equipment; the heated liquid medicine is pumped out through the peristaltic pump, and the flow rate can be adjusted according to demand.

[0019] Example

[0020] like Figure 1As shown, a constant temperature enema device includes a rectangular box body. A cover plate is arranged above the box body to keep the box body airtight, ensure that the water bath liquid inside is clean, and better keep warm.

[0021] like Figure 2 As shown, the liquid medicine container and the catheter are placed in the box. One end of the catheter is connected to the liquid medicine container, and the other end passes through the pipe groove of the peristaltic pump and extends out of the box to connect the enema device. A heater and a temperature sensor are set at the bottom of the box, both of which are connected to the temperature controller. The temperature controller can also be provided with a display panel for displaying the preset water bath temperature and the water bath temperature collected by the temperature sensor. When the water bath temperature collected by the temperature sensor reaches the preset temperature, the peristaltic pump can be turned on to pump out the liquid medicine and perform the enema operation.

[0022] like Figure 3 As shown in the figure, a pump head is arranged in the pipe groove of the peristaltic pump, and a movable slider is arranged above the pump head. The slider is fixed on the pipe groove with a thread. When in use, the slider can be rotated to adjust the pipe groove size to adapt to catheters of different specifications. The flow rate of the liquid medicine can be adjusted by the rotation speed of the pump head.

[0023] like Figure 4 As shown, the side wall of the box is also provided with grooves for fixing the horizontal and vertical partitions. The horizontal partition is to prevent the liquid medicine container and the catheter from directly contacting the heater at the bottom of the box so as to make the temperature of the liquid medicine too high. The vertical partition can divide the box into two compartments for storing the liquid medicine container and the catheter. According to the size and type of the instrument and the length of the catheter, the horizontal and vertical partitions can be inserted into different slots to adjust the size of the compartment to accommodate different instruments.

[0024] When in use, open the cover, first connect the disposable liquid medicine container to the catheter and put it into the box, and place the partition to adjust the size of the compartment according to the specifications of the device and the length of the catheter. Place the liquid medicine container in the first compartment, coil the catheter in the second compartment, and extend the catheter through the pipe groove of the peristaltic pump out of the box to connect the enema device. Then fill it with pure water as a water bath, and the water bath should submerge the liquid medicine container and the catheter. The heater set at the bottom is used to heat the water bath in the box, and the water bath is used to heat the liquid medicine in the liquid medicine container and the catheter. The temperature sensor collects the temperature of the water bath and then feeds it back to the temperature controller. The temperature controller controls the heater to work or stop working according to the preset target temperature and the actual temperature of the water bath collected to maintain a constant temperature. The peristaltic pump adjusts the size of the pipe groove through the slider of the pump body to adapt to catheters of different outer diameters, while ensuring that there is moderate pressure on the catheter to cooperate with the pump head. The pump head group in the peristaltic pump rotates simultaneously to alternately squeeze and release to pump the liquid medicine. During operation, the rotation speed of the peristaltic pump head can also be changed according to the medication needs to adjust the flow rate of the drug solution.
