[0036] Figure 3A and Figure 3B is a cross-sectional view of a portable fluid infusion device including a transmission according to another embodiment of the present invention, wherein, Figure 3A is a schematic diagram of the inflatable bladder in a compressed state, Figure 3B It is a schematic diagram of the inflatable pouch when it is in an inflated state. Such as Figure 3A and Figure 3B As shown, the structure of the fluid infusion device including the transmission device is substantially the same as that of the fluid infusion device in the first embodiment, except that the telescopic part 22 of the transmission device 2 is an inflatable bladder.

[0037] In this embodiment, for example, the expandable bladder can be made of a flexible waterproof material (so that hydraulic fluid does not enter the space between the bladder and the piston 61), one end is connected to the piston 61, and the other end is connected to the piston 61. It is in fluid communication with ...

[0040] Figure 4 is a cross-sectional view of a portable fluid infusion device including a transmission according to yet another embodiment of the present invention. Such as Figure 4 As shown, the structure of the fluid infusion device including the transmission device is substantially the same as that of the fluid infusion device in the first embodiment, except that the structure of the transmission device 3 is different.

[0041] In this embodiment, the transmission device 3 may include: a force transmission unit 31 connected to the piston 61 and configured to be moved to transmit power to the piston 61 after receiving the power F1; and a guide member 32 connected to the piston 61. The force transmission unit 31 is in contact with each other for guiding the movement of the force transmission unit 31 , and is configured to change the power transmission direction by changing the movement direction of the force transmission unit 31 . The force transmission unit 31 can be sel...

Abstract

The invention provides transmission device-equipped portable fluid infusion equipment for administrating a drug to a patient and a manufacturing method thereof. The portable fluid infusion equipment comprises a shell, a fluid storage chamber, an infusion assembly and the transmission device, wherein the fluid storage chamber is positioned inside the shell and is used for accommodating infused fluid; the fluid storage chamber comprises a near end and a far end; a movable piston is arranged inside the fluid storage chamber; the piston is arranged for transmitting the infused fluid to the patient when the piston moves from the far end to the near end; the infusion assembly is positioned at the near end of the fluid storage chamber, is in fluid communication with the fluid storage chamber, and is used for transmitting the infused fluid in the fluid storage chamber to the patient; the transmission device is connected with the fluid storage chamber through the piston, is arranged for receiving power, changing the direction of the power and exerting the power onto the piston to move the piston so as to transmit the infused fluid to the patient through the infusion assembly. After implementation of the transmission device-equipped portable fluid infusion equipment and the manufacturing method, the size of the infusion equipment can be significantly reduced, and the patient can wear or carry about the infusion equipment more easily.

Description

technical field [0001] The present invention relates to the field of fluid delivery, and more specifically relates to a portable fluid infusion device including a transmission device for administering medicine to patients and a manufacturing method thereof. Background technique [0002] Diabetes is a metabolic disease characterized by high blood sugar. Hyperglycemia is generally due to defective insulin secretion or impaired biological action, or a combination of both. Long-term high blood sugar in diabetic patients will lead to chronic damage and dysfunction of multiple body organs (such as eyes, kidneys, heart, blood vessels, nervous system, etc.). [0003] The clinical diagnosis of diabetes can be divided into type 1 diabetes and type 2 diabetes. Type 1 diabetes, also known as insulin-dependent diabetes, usually occurs in childhood or adolescence, and is a congenital, family-genetic disease. Type 1 diabetes is an autoimmune disease in which the body's immune system att...
