Description

Anesthesia head frame for operation

technical field

The utility model relates to a medical auxiliary device, in particular to an anesthesia head frame.

Background technique

The anesthesia head frame used in the operation is a device that strictly distinguishes the sterile area from the sterile area. It is used to support the sterile area, cover the patient, expose the face, and facilitate the anesthesiologist to observe the patient's respiratory passage.

With the development of medical technology, more requirements are put forward for the use of anesthesia head frame. The anesthesia head frame commonly used in the prior art is a frame body in the shape of a door, which is fixed on the operating bed and plays the role of supporting the sterile surgical dressing. However, since the supporting point is only a rod, the supporting part is too large. Concentrated and single, and the surgical towel is relatively large, so the hem of the towel will stick to or cover the patient's face, which not only affects the normal breathing of the patient, but also makes the patient feel depressed, irritable and poorly ventilated. It is inconvenient for anesthesiologists to assist patients in oxygen inhalation operations and observation of vital signs.

In the process of preparing for anesthesia, many anesthetics and instruments are needed, and the operation rhythm is often very tight, and every second counts. In order to facilitate the operation, sometimes the doctor will spread a sterile towel on the patient, and place the medicine used for anesthesia induction on the tray and Relevant equipment during general anesthesia (such as: tracheal intubation, etc.) is placed on the sterile towel. On the one hand, this operation does not conform to the norms (contrary to the concept of love and injury and the principle of medical aseptic operation), and on the other hand, the tray is not easy to place stably .

Detailed ways

The structure of the traditional anesthesia head frame is simple, it can only support the dressing, and can no longer meet the needs of surgery; especially the problem of placing surgical trays, ventilators, and heat-humidity exchanger pipelines during the operation, it was once difficult for the operation The smooth progress has many effects.

This program proposes a multifunctional surgical anesthesia head frame:

An anesthesia head frame for surgery, comprising a head frame, the head frame includes a symmetrically arranged telescopic rod 12 and a cross bar connecting the telescopic rod 12, a retractable support fan is arranged on the cross bar; There is a universal mechanism 1, and the universal mechanism 1 is connected to the fixed column 10 through a strut 103, and the fixed column 10 is provided with a soft card 9.

The supporting fan is composed of two parts. Its appearance structure is circular, and it can be closed and shrunk like a fan. After shrunk, as shown in Figure 2, it saves space. When the supporting fan is stretched, a storage space is formed on the fan, which can mainly play two roles:

First, the surgical drape needs to be bypassed from the head frame, so when the support fan is stretched, and then the surgical drape is placed, then due to the function of the support fan, it will be under the support fan, that is, the position of the patient's face cloth Open a relatively wide space, so that the patient's face cloth will not be blocked by the edge of the drooping towel, so as to maintain air circulation and smooth breathing, and also facilitate the setting of the ventilator circuit;

Second, after the towel is covered on the support fan, the surgical tray can be placed on it after laying a sterile towel; the setting position of the head frame determines that it is closer to the surgical site, so it is more convenient to operate after placing the surgical tray The process of taking Chinese medicines and equipment.

The structure of the support fan that is stretched out into a circle is based on the consideration that the area of the circle is relatively large, and because its edges are arc-shaped, it is not easy for the operator to collide or be injured.

In this solution, the two support rods of the head frame adopt telescopic rods 12, which can facilitate the adjustment of the height of the head frame, thereby adjusting the height position of the towel and the tray.

The universal mechanism 1 is arranged on the cross bar. Since the ventilator is generally arranged next to the operating bed at the front end of the head frame, it is better to adjust the strut 103 to be located at the front of the head frame. The universal mechanism 1 can effectively fix the fixing rod and the fixing column 10 in a relatively wide range, so that the threaded pipe and other pipelines of the ventilator can be fixed in multiple positions; after the pipeline is fixed, it will no longer Influenced by the hem of the wrap.

The soft clamp 9 is used to clamp the threaded pipe and other pipes. Various structures can be used, such as soft clamps. After the threaded pipe and other pipes are fixed, the pipeline will not be scattered, and it will also restrict the pipeline. Function, when the pipeline is accidentally pulled or dragged, the pipeline will not be easily dislodged, which improves safety.

In order to make this scheme have a better application effect, the following features are further proposed:

The support fan includes a rotating shaft 2 arranged in the middle of the cross bar, on which a plurality of fan blades 3 of the same size are installed, and the two fan blades 3 at the bottom end are fixedly connected with the cross bar, and the rest of the fan blades 3 are closed when they are not opened. Symmetrically arranged on both sides of the rotating shaft 2, the fan blades 3 on both sides of the rotating shaft 2 can be opened along the rotation direction of the rotating shaft 2 to form a half fan, and the two half fans are connected by the fixing card 4 to form a supporting fan.

The support fan is divided into two parts, and each part has the same number of fan blades 3 . Among them, the two fan blades 3 closest to the cross bar are symmetrically consolidated on the cross bar, and the remaining fan blades 3 are located above the two fan blades 3; when in use, it is only necessary to place the two stacks of fan blades along the same direction on the circumference. 3. Pull them apart in sequence to form a support fan. The fan blades 3 at the contact part of the two supporting fan surfaces are symmetrically provided with fixing clips 4 to relatively fix the two supporting fan surfaces to form the entire supporting fan surface.

The axial direction of the rotating shaft 2 is parallel to the telescopic direction of the telescopic rod 12 .

The rotating shaft 2 is used as the installation shaft of the fan blade 3, and its axial direction is perpendicular to the supporting fan surface. In order to ensure the stability of the surgical tray during the operation, the support fan should be in a horizontal state; and when fixed, the axial direction of the telescopic rod 12 is generally perpendicular to the horizontal plane, so the axial telescopic rod 12 of the rotating shaft 2 is set to be parallel.

The universal mechanism 1 includes an adjustment cylinder 101, and the adjustment cylinder 101 is provided with an upper chamber 106 and a lower chamber 105 which are not communicated in the axial direction, wherein the upper chamber 106 communicates with the upper end of the adjustment cylinder 101, and the upper chamber 106 is used for and The cross bar is installed in cooperation; the lower cavity 105 is connected with the lower end of the adjustment cylinder 101, and an adjustment ball 102 that can rotate in the cavity is arranged in this cavity. The diameter of the adjustment ball 102 is larger than the diameter of the lower end of the adjustment cylinder 101. Consolidate the support rod 103, the support rod 103 protrudes from the lower cavity 105 and is fixed on the fixed column 10; Bolt 104.

As shown in Fig. 3, a universal mechanism 1 with simple structure and convenient adjustment is provided.

The cross bar is provided with a boss, which can be directly inserted into the upper cavity 106 to complete the installation process; and the lower cavity 105 can adjust the angle of the adjustment ball 102 relative to the adjustment cylinder 101 in a wide range through the setting of the adjustment ball 102. Adjust within. This is a wide-angle adjustment method. The adjustment cylinder 101 is fixed on the cross bar, and the adjustment ball 102 drives the pole 103 to change its position, which adjusts the position of the fixed column 10 . The position of the fixing post 10 determines the position of the soft card 9, which facilitates the fixing of the pipeline. After the position is adjusted,

By tightening the fixing bolt 104, the fixing bolt 104 moves along the direction close to the adjusting ball 102, and finally comes into close contact with the adjusting ball 102 to limit the rotation of the adjusting ball 102, and now the universal mechanism 1 is fixed. Since the pipeline is relatively light, this structure can play a good supporting and restricting role.

The soft card 9 is distributed axially along the fixed column 10 on the side of the fixed column 10, and the soft card 9 is an elastic card, and its cross section is a curved shape.

The soft card 9 is an elastic structure, the cross section is a superior arc, that is, C-shaped, and its interior is a circular groove, which can accommodate the threaded pipe or other pipes of the ventilator. The diameter of the circular groove is slightly larger than the threaded pipe or other pipes diameter, but the distance between the opening of the soft card 9 is less than the diameter of the threaded pipe. When the threaded pipe needs to be fixed, it is only necessary to break open the opening of the soft card 9, insert the threaded pipe into the circular groove of the soft card 9, loosen the soft card 9, and the threaded pipe can be well fixed due to its elasticity and limit it. Depending on the situation, a plurality of soft cards 9 can be distributed on a fixed column 10, and other pipelines and lines can also be fixed.

The lower end of the telescopic rod 12 is provided with a bayonet 8, and the bayonet 8 is composed of two horizontal plates arranged in parallel. The distance between the two horizontal plates is greater than the thickness of the edge of the operating bed. When the edge is stuck in the bayonet 8, it is fastened by rotating the fastening knob 7.

The entire head frame is fixed on the operating bed and needs to be firmly fixed, so the structure shown in the figure is adopted. When fixing, the two bayonets 8 are respectively stuck on both ends of the operating bed, and then the fastening button 7 is tightened. 7 When advancing, firmly fix between the edge of the operating table and the horizontal board.

In order to facilitate the installation of the head frame, the telescopic rod 12 should also have a certain degree of elasticity; in addition, the cross rod can also be made into a telescopic and fixed rod to adapt to different operating bed widths.

The telescopic rod 12 is a sleeve rod, on which the height adjustment button 6 is installed. Before use, unscrew the height adjustment button 6, adjust the length of the telescopic rod 12, and then tighten it; 12 is provided with scale 5.

A reflective mirror 11 is arranged on the pole 103, which is connected with a soft rod to facilitate adjustment of its angle and position. After the head frame is set up, the position of the reflective mirror 11 is adjusted to face the patient’s face, so that the doctor only needs to look up during the operation. The present condition of the patient can be learned by seeing the reflector 11.
