Description
Technical field
This utility model relates to a kind of medical diagnosis measurement device, particularly a kind of finger clip type blood oxygen probe.
Background technology
Along with the development of medical industry, the instrument and equipment of the oxygen content of various monitoring and detection people has become more and more general, wherein has a kind of blood oxygen probe, it is enclosed within the finger tips of people, can measure the physiological parameters such as the oxygen content of human body.The main body of this blood oxygen probe is that elastomeric material is made, and main body is pancake hole structure, and the direction in hole is the direction of principal length, and the cross section in hole is for diminish gradually.Less one end, hole is a narrow slit, and narrow slit is more smaller than finger.Finger stretches into from the large end in hole, and by elastomeric elasticity, finger tip is clamped in narrow slit.The both sides of narrow slit are embedded with sensor respectively, the signal of side sensor emission is by form (transparent structural member), through finger tip, receive by opposite side sensor, the signal received is sent in processor through electric wire to be analyzed, by analyzing the signal of contrast transmitting and receiving, the physiological parameters such as the oxygen content of measured just can be known.
This probe requires sensor, electric wire is embedded in interiors of products exactly, to ensure the presentation quality of product.Traditional sensor and electric wire are generally after welding, are encapsulated by pad by heat-shrink tube, or sensor and electric wire are fixed on special pcb board.
After sensor and wire welding, the mode that pad is encapsulated by heat-shrink tube, not only increases human weld's technique, and after pad comes off, not easily discovers.And mode sensor is fixed on special pcb board, need to increase PCB technology, increase structural volume.These two kinds of modes not only manufacturing process loaded down with trivial details, assembling more difficult, and connection welding easily comes off, unsightly.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of finger clip type blood oxygen probe, it makes emission sensor position more accurate, solve traditional finger clip type blood oxygen probe emission sensor and exposed with electric wire connection welding, easily come off, unsightly and not easily assemble, the technical problem such as non-watertight.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
A kind of encapsulating structure of finger clip type blood oxygen probe, the emission sensor comprising main circuit board in the upper finger clamp assembly that is arranged on receiving tube in the lower finger clamp assembly of finger clip type blood oxygen probe and is arranged on finger clip type blood oxygen probe and be electrically connected with main circuit board, described emission sensor is electrically connected with main circuit board by electric wire, electric wire and main circuit board, emission sensor is connected by welding manner, described electric wire, emission sensor and electric wire weld formed solder joint and are packaged into one by a transparent coated housing with emission sensor, electric wire is uniform intervals arrangement in transparent coated housing, the transparent coated housing at the corresponding emission sensor back side is provided with louvre.
This utility model improves further and is: described transparent coated housing is also arranging louvre near solder joint with between the electric wire of emission sensor, and louvre is herein the through hole penetrating transparent coated housing.
Owing to adopting technique scheme, the beneficial effect that this utility model produces is:
The encapsulating structure of a kind of finger clip type blood oxygen probe of the present utility model, by emission sensor and be packaged in the coated housing of transparent plastic cement with electric wire connection welding, single injection-molded, can use always.This embedded encapsulating structure, has not only saved human weld's process procedure, and connection welding difficult drop-off, and appearance looks elegant, easily assemble, and also serves waterproof effect.It makes emission sensor position more accurate, the emission sensor and the electric wire connection welding that solve traditional blood oxygen probe be exposed, easily come off, unsightly and not easily assemble, the technical problem such as non-watertight.Being provided with of louvre is beneficial to the heat radiation of emission sensor and electric wire, solder joint, extends product service life.
