Problems solved by technology

In recent years, with the gradual maturity of automatic needling robot technology, the accuracy of the needling process has been greatly improved, and the needling time has also been shortened. However, the hemostasis and pressing of the needle hole after the needling still needs to be done manually, relying more on the nurses. Experience and the patient's own cooperation, especially for the elderly or patients with limited mobility, there are often various difficulties in pressing to stop bleeding

Embodiment 1

[0029] Such as Figure 1~3 As shown, this embodiment provides an automatic hemostasis presser, which includes a bracket module 1 , a transmission module 2 , an arm pressing module 3 and an arm support module 4 .

[0030] The support module 1 comprises a base 12 and an annular track frame 11, the annular track frame 11 is vertically arranged on the base 12, and the inside of the annular track frame 11 is a cavity to form a track; the base 12 adopts a hollow triangular shape, and the interior is divided into two In part, while reducing material costs, the load-bearing structure is optimized, and the integrity of the device is also improved, making it more beautiful.

[0031] The arm pressing module 3 and the arm supporting module 4 are respectively arranged on the top and the bottom of the ring-shaped track frame 11 , and both can be stretched up and down in the ring-shaped track frame 11 . Specifically, the arm support module 4 includes an arm support plate 43 , a return sprin...

Embodiment 2

[0035]The basic structure of this embodiment is the same as that of Embodiment 1, the difference is that: the arm pressing module 3 includes a pressing mechanism 32, which is installed on the bottom of the arm pressing module 3, as Figure 5 and Figure 6 shown. The pressing mechanism 32 includes a pressing push rod 321 , a first motor 322 and an ultrasonic sensor. The first motor 322 drives the pressing push rod 321 to move up and down through the gear structure, and the bottom end of the pressing push rod 321 is a suction cup 321a, which adopts an existing vacuum suction cup. The ultrasonic sensor is installed on the limit of pressing push rod 321 and is used for detecting whether the lower arm is within the set distance.

[0036] The working process and principle of this embodiment are as follows: when in use, first suck a hemostatic patch under the suction cup 321a. After the arm pressing module 3 descends, the ultrasonic sensor responds and starts monitoring. When the...

Embodiment 3

[0038] This embodiment is an improved version of Embodiment 2, and the arm pressing module 3 also includes a tourniquet replacement unit 33, such as Figure 7 shown. The tourniquet replacement unit 33 includes a pulley 332 and a second motor 331 . The second motor 331 is connected to the rotating shaft of the pulley 332. The tourniquet 5 is wound on the pulley 332. The tourniquet replacement unit 33 is provided with an outlet slot 333 facing the push rod 321, so that one end of the tourniquet 5 passes through the outlet slot. 333. The tourniquet 5 is formed by connecting hemostatic sheets with a protective film, and the adjacent hemostatic sheets are electrically connected. A knife edge can also be set at the bottom of the outlet groove 333 . After one pressing operation is finished, the second motor 331 can drive the pulley 332 to make the tourniquet 5 protrude from the outlet slot 333 . Press the suction cup 321a of the push rod 321 to start sucking the tourniquet 5, and...

Abstract

The invention relates to an automatic hemostasis presser, comprising a bracket module, a transmission module, an arm pressing module and an arm support module, the bracket module includes a base and a ring track frame, the ring track frame is vertically arranged on the base, and the arm presses The module and the arm support module are arranged on the top and bottom of the ring track frame respectively, and can be stretched up and down in the ring track frame. The transmission module includes two transmission units symmetrically arranged on both sides of the ring track frame. Each transmission unit includes a sliding block, a first connecting rod and a second connecting rod, the sliding block is arranged on the track of the ring-shaped track frame, the two ends of the first connecting rod respectively rotate and connect the sliding block and the arm pressing module, and the second connecting rod The two ends of the bar are respectively connected with the sliding block and the arm support module. Compared with the prior art, the present invention can realize pressing and locking through a purely mechanical structure, and perform hemostatic pressing, and the patient only needs to place the arm, and the operation is quick and convenient.

Description

technical field [0001] The invention relates to medical auxiliary equipment, in particular to an automatic hemostasis presser. Background technique [0002] In medical practice, venous blood drawing is a routine operation in nursing work. After venous blood drawing and needle withdrawal, bleeding at the puncture point and spotting may occur clinically. Negligence, carelessness, and weak sense of responsibility at work cause patients to experience pain and bleeding spots due to improper needle withdrawal, and also cause psychological unhappiness and dissatisfaction with nursing work for patients, which may easily cause disputes and affect the quality of nursing care. Insufficient compression time and incorrect location can cause bleeding. Generally, local pressure is required for 3 to 5 minutes after the needle is pulled out, but after the needle is pulled out, most of the nurses hand over the pressure to the patient or family members, without specifying the time of pressing...
