Description

Novel pneumatic type rehabilitation robot glove

Technical Field

The invention relates to a novel pneumatic type rehabilitation robot glove, and belongs to the technical field of rehabilitation robot gloves.

Background

The existing pneumatic rehabilitation robot glove is single in overall shape in the design of an airflow passage, a single thin tube is mostly adopted for leading in, then the pneumatic muscle inflation and deflation operation of each finger is realized through a vertical bifurcation mode, and because an air inlet tube is too thin and adopts the vertical bifurcation mode, the pipeline resistance and the air flow vortex are easily formed, so that the force of the tail end of the glove executing end acting on the finger of a patient is insufficient, and in particular, the relaxation training can not be well carried out aiming at the finger spasm of a patient with moderate muscle tension; secondly, because each air outlet pipe and the air inlet pipe have obvious turning angles and obvious differences, the phenomenon that the pressure which can be accepted by pneumatic muscles on a single finger or a plurality of fingers is insufficient easily occurs, so that the movement angle of the fingers under the assistance of the pneumatic rehabilitation robot gloves is insufficient, and the treatment condition of the fingers is poor.

Disclosure of Invention

The invention aims to provide a novel pneumatic rehabilitation robot glove which can ensure that pneumatic muscles of fingers can obtain enough pressure and avoid uneven stress of the pneumatic muscles of the fingers.

In order to achieve the purpose, the invention is realized by adopting the following technical scheme:

the invention provides a novel pneumatic type rehabilitation robot glove which comprises an input port, five output ports, a cavity and an air outlet pipe, wherein the input port is in a duck tongue shape and has no corner, the input port is connected with the five output ports through the cavity, the upper end of the cavity is in the duck tongue shape and has no corner, the lower end of the cavity is in a round-angle cuboid shape, the five output ports are arranged at the lower end of the cavity at equal intervals and are connected with the lower end of the cavity, the five output ports are respectively connected with pneumatic muscles of a thumb, a forefinger, a middle finger, a ring finger and a little finger through the air outlet pipe, and the pneumatic muscles of the thumb, the forefinger, the middle finger, the ring finger and the little finger respectively receive gas.

Further, the aperture of the input port is larger than the aperture of each output port.

Further, the gloves still include the intake pipe, the input port has the air pump through intake pipe sealing connection, the air pump passes through the intake pipe and transmits gas for the input port.

Furthermore, the cavity is attached with a bottom support, and the lower end of the cavity in the shape of a round-corner cuboid is arranged on the bottom support.

Further, the bottom support is glued on the glove.

Furthermore, the glove is made of plastic.

Compared with the prior art, the invention at least has the following beneficial effects:

the input port is shaped like a duck tongue, so that the gas flow at the input port can be increased, the input port has no corner, the gas flow resistance can be reduced, and the gas flow vortex can be avoided, so that the gas flow received by the pneumatic muscles of all the fingers can be obviously improved, and the pneumatic muscles of all the fingers can obtain enough pressure;

the upper end of the cavity is in a duck tongue shape without a corner, and the lower end of the cavity is in a round-corner cuboid shape, so that the whole cavity has no obvious corner, and gas can quickly flow to pneumatic muscles of all fingers;

five delivery outlets are arranged at the lower end of the cavity at equal intervals and connected with the lower end of the cavity, and each delivery outlet can almost simultaneously receive gas with similar flow, so that pneumatic muscles of each finger can be simultaneously contracted to obtain pressure with similar size to complete treatment of the finger of the patient, and uneven stress of the pneumatic muscles of each finger can be avoided.

Detailed Description

The invention is further described below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

It should be noted that in the description of the present invention, the terms "upper" and "lower" indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and the terms "inner" and "outer" respectively refer to directions toward and away from the geometric center of a specific component, and are only for convenience of description of the present invention and do not require that the present invention must be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

As shown in fig. 1 to 3, the novel pneumatic rehabilitation robot glove provided by the embodiment of the invention comprises an input port, five output ports, a cavity, an air outlet pipe and an air inlet pipe, wherein the input port is hermetically connected with an air pump through the air inlet pipe, the air pump transmits air to the input port through the air inlet pipe, the input port is shaped like a duck tongue without a corner, the flow rate of inlet air can be increased, the airflow resistance is reduced, and the occurrence of air flow vortex is avoided, so that the air flow received by the pneumatic muscles of each finger is remarkably increased, the pneumatic muscles of each finger can obtain enough pressure, and further, effective relaxation training can be performed on finger spasm of a patient with moderate muscle tension.

The input port is connected with five output ports through the cavity, the aperture of the input port is larger than that of each output port, and sufficient gas flow is ensured to flow into each output port; the upper end of the cavity is in a duck tongue shape without corners, and the lower end of the cavity is in a round-corner cuboid shape, so that the whole cavity has no obvious corners, and gas can flow to pneumatic muscles of all fingers quickly.

The five output ports are arranged at the lower end of the cavity at equal intervals and connected with the lower end of the cavity, the five output ports are respectively connected with pneumatic muscles of a thumb, an index finger, a middle finger, a ring finger and a little finger through air outlet pipes, and the pneumatic muscles of the thumb, the index finger, the middle finger, the ring finger and the little finger respectively receive air transmitted by the five output ports through the air outlet pipes, so that the output ports can almost simultaneously receive air with similar flow, the pneumatic muscles of each finger can be simultaneously contracted, the pressure with similar size is obtained to complete the treatment of the finger of a patient, and the uneven stress of the pneumatic muscles of each finger can be avoided.

In this embodiment, the cavity is attached with a bottom support, the lower end of the cavity in the shape of a rounded rectangle is arranged on the bottom support, and the bottom support is glued on the glove; the glove is made of plastic.
