Embodiment 1

[0028] Such as Figure 1 to Figure 3 As shown, the direct-connected intestinal fluid reinfusion device provided in this embodiment includes a reinfusion tube 1 and a magnetic suspension pump 2 located in the middle of the reinfusion tube 1 . The magnetic rotor 21 is located in the housing chamber 11, and the stator core 22 of the magnetic levitation pump 2 is located on the outer wall of the housing chamber 11. After the magnetic levitation pump 2 works, the intestinal juice is pumped back to the human body through the magnetic levitation pump 2. For proximal intestinal fistula, it is often necessary to use an intestinal fluid reinfusion device to reinfuse intestinal fluid to ensure the normal nutrient absorption of children. The frequency of the first end of the duodenum and the main working area is about 10-12 times / min. While the terminal frequency is 6-9 times / min, the rate of intestinal peristalsis is usually about 0.5-2.0 cm / s. In specific use, when intestinal fluid rei...

Embodiment 2

[0034] The direct-connected intestinal fluid reinfusion device provided in this embodiment includes a reinfusion tube 1 and a magnetic levitation pump 2 located in the middle of the reinfusion tube 1 . The middle part of the reinfusion tube 1 is provided with an accommodation cavity 11 , and the permanent magnet rotor 21 of the magnetic levitation pump 2 Located in the accommodation chamber 11 , the stator core 22 of the magnetic levitation pump 2 is located on the outer wall of the accommodation chamber 11 .

[0035] Such as Figure 4 and Figure 5 As shown, the difference between embodiment two and embodiment one is:

[0036] The proximal plumb head 121 and / or the distal plumb head 131 of the direct-connected intestinal fluid reinfusion device provided in this embodiment are all configured as separate plum blossom heads, and one end of the separate plum blossom head is provided with a connecting tube 4, and each round A fixed cylinder 400 with a through hole is arranged in...

Embodiment 3

[0038] The direct-connected intestinal fluid reinfusion device provided in this embodiment includes a reinfusion tube 1 and a magnetic levitation pump 2 located in the middle of the reinfusion tube 1 . The middle part of the reinfusion tube 1 is provided with an accommodation cavity 11 , and the permanent magnet rotor 21 of the magnetic levitation pump 2 Located in the accommodation chamber 11 , the stator core 22 of the magnetic levitation pump 2 is located on the outer wall of the accommodation chamber 11 .

[0039] Such as Figure 6 and Figure 7 Shown, the difference between embodiment three and embodiment one, embodiment two is:

[0040] The direct-connected intestinal fluid return device provided in this embodiment also includes a rotor cleaner, which is used to clean the permanent magnet rotor 21, and a part of the pipeline of the rotor cleaner is fixed on one side of the stator core 22. When the magnetic levitation pump 2 is cleaned, the proximal intestinal tube 12 i...

Abstract

The invention discloses a direct-connection type intestinal juice back-conveying device, and belongs to the field of intestinal juice recovery devices. The direct-connection type intestinal juice back-conveying device comprises a back-conveying pipe and a magnetic suspension pump located in the middle of the back-conveying pipe, wherein a containing cavity is formed in the middle of the back-conveying pipe, and a rotor of the magnetic suspension pump is located in the containing cavity. The direct-connection type intestinal juice back-conveying device can directly pump back intestinal juice, is simple in structure, can keep good working stability when the human body is in a moving state, and is convenient to carry and easy to use.

Description

technical field [0001] The invention relates to the field of intestinal fluid return transfusion devices, in particular to a direct-connected intestinal fluid return transfusion device. Background technique [0002] The common feature of neonatal enterostomy is that the intestinal tract is pulled out of the abdominal wall, and two stoma openings are routinely formed. Due to the limited digestion and absorption in the proximal intestine, a large amount of intestinal fluid is easily lost, causing a series of pathophysiological changes such as water-electrolyte and acid-base balance system disorders and malnutrition, which seriously affect the growth and quality of life of children. Since the fecal discharge from the proximal stoma in children contains partially digested nutrients, they can be reabsorbed and utilized by the intestinal tract. Therefore, reinfusing the feces discharged by the child through the proximal stoma into the distal intestine through the distal stoma can...
